Climate Change Authority's Move To Canberra Raises Independence Concerns

The Climate Change Authority will be moved from Melbourne to Canberra within the next fortnight, putting its independence from government under the spotlight.
A spokesperson for the Department of Environment has confirmed the move in "mid-September" to Guardian Australia, and said it was being done "in order to improve its operating efficiency".
Guardian Australia understands none of the authority's staff, besides the chief executive, will stay with it after the move, which has been known about in relevant circles for some time.
The move has raised concerns it will bring the authority, which was set up in 2011 in Melbourne as an independent statutory agency, closer to government and limit its independence.
The Department of Environment spokesperson said the authority would continue to have "its own staff". But whether those staff would be on secondment from the department is not yet known.
Several people close to the authority warned that since the expert staff of the authority did much of the agency's work – including writing the reports that are directed and signed off by the board members – how close they were to government could affect the degree of independence it maintained.
Bernie Fraser, former chair of the Climate Change Authority and former chair of the Reserve Bank of Australia, told Guardian Australia that "the independence is one of the great features of bodies like the Climate Change Authority".
Fraser said the personnel – both the staff and the board – need to work to uphold the independence of the authority. He said when he was head of the authority, the staff were "tremendously impressive".
"Unfortunately that started to erode, after the change of government, and the talk of abolishing the authority – those good people thought the government isn't going to listen and is going to get rid of the authority at the first opportunity," Fraser said.
He said there was "something to" the concerns about independence if it was moved to Canberra, and particularly if the staffing turned out to be seconded from the department rather than hired independently.
Ian Chubb, a former member of the authority and the former chief scientist of Australia, said if the board was expert enough, then the independence of the staff shouldn't impact the independence of the authority itself.
"I don't think moving the secretariat to Canberra is moving the authority closer to government, other than literally," he told Guardian Australia. "There are lots of organisations in Canberra at arm's length from government. The independent board ought to have enough knowledge collectively not to let the wool get pulled over their eyes."
The Coalition attempted to abolish the Climate Change Authority in its last term in government but failed to get the legislation through the Senate, and continues to maintain its policy that it should be abolished.
In the Coalition's 2016-17 budget, the Climate Change Authority was provided with an operating budget from existing Department of Environment funds until the end of 2016 only.
The move follows a dispute between members of the authority over a report on whether Australia should have an emissions trading scheme, leading to two members releasing a "minority report" and receiving a sharp rebuke from the authority's chair, Wendy Craik.
Craik released a statement saying their report was "misleading". She said while it "purports to be a minority report to the authority's third and final report of its special review", it "was not released or endorsed by the authority, and has no status as an authority report".
Asked about whether the two dissenting members would continue on the board of the authority, a spokeswoman for the Climate Change Authority told Guardian Australia: "Whether the two members who wrote the dissenting report continue as members of the authority is a matter for them."
Both dissenting members, the economist Clive Hamilton and the climate scientist David Karoly, said they would not resign over the matter, and they didn't believe there were any grounds for them to be dismissed.
Fraser said he had read both the majority report and the minority report. "I thought the points in the minority point were very well made and deserve serious consideration, he told Guardian Australia.
Asked about the dispute and the future of the organisation, the environment and energy minister, Josh Frydenberg, said the disagreement was a matter for the authority but the government had no plans to commission any further reports from it.
The authority is still required to complete two more reports: a review of the carbon farming initiative legislation and a review of the national greenhouse and energy reporting legislation.

Future Fisheries Can Expect $10-Billion Revenue Loss Due To Climate Change

Lab Manager - University of British Columbia

Climate change impacts such as rising temperatures and changes in ocean salinity, acidity, and oxygen levels are expected to result in decreased catches

Global fisheries stand to lose approximately $10 billion of their annual revenue by 2050 if climate change continues unchecked, and countries that are most dependent on fisheries for food will be the hardest hit, finds new University of British Columbia research.
Climate change impacts such as rising temperatures and changes in ocean salinity, acidity, and oxygen levels are expected to result in decreased catches, as previous research from UBC's Institute for the Oceans and Fisheries has found. In this study, the authors examined the financial impact of these projected losses for all fishing countries in 2050, compared to 2000.
"Developing countries most dependent on fisheries for food and revenue will be hardest hit," said Vicky Lam, a postdoctoral fellow at UBC's Institute for the Oceans and Fisheries, and the study's lead author. "It is necessary to implement better marine resource management plans to increase stock resilience to climate change."
While many communities are considering aquaculture, also known as fish farming, as a solution to ease the financial burden of fishing losses and improve food security under climate change, when researchers examined the growing industry, they found it may exacerbate the negative impact on revenues
"Climate adaptation programs such as aquaculture development may be seen as a solution," said William Cheung, associate professor at UBC's Institute for the Oceans and Fisheries and a study co-author. "However, rather than easing the financial burden of fishing losses and improving food security, it may drive down the price of seafood, leading to further decreases in fisheries revenues."
The researchers used climate models from the Intergovernmental Panel on Climate Change to examine the economic impact of climate change on fish stocks and fisheries revenues under two emission scenarios. In a high emission scenario, the rates continue to rise unchecked, while a low emission scenario meant ocean warming is kept under two degrees Celsius.
"Global fisheries revenues amount to about $100 billion every year," said co-author, Rashid Sumaila, professor at UBC's Institute for the Oceans and Fisheries and Liu Institute for Global Studies. "Our modeling shows that a high emissions scenario could reduce global fishing revenue by an average of 10 per cent, while a low emissions scenario could reduce revenues by 7 per cent."
The researchers found the countries that rely highly on fish are the most vulnerable, including island countries like Tokelau, Cayman Islands, and Tuvalu. Meanwhile, many developed countries, such as Greenland and Iceland, could see revenue increases as fish move into cooler waters.
The study was published Sept. 7 in Scientific Reports.

Solar Power Sector Handed Huge Boost By ARENA Funding

Fairfax - Peter Hannam

Australia is set to triple its large-scale solar energy capacity after funding from a threatened federal agency helped drive down costs almost to those of wind farms.
The Australian Renewable Energy Agency (ARENA) announced the 12 projects that will share part of its latest funding round of $92 million on Thursday.

UNSW researchers break world record for solar cell efficiency. Australian researchers find a way to hugely increase the efficiency of solar panels.

Queensland was a big winner, landing six of the projects, while NSW won five and WA the other one. (See map below.)

The plants will generate about one-tenth of the power needed to meet Australia's 2020 Renewable Energy Target, supply enough electricity for 150,000 average homes and create 2,300 direct jobs alone, ARENA said.
The agency's chief executive, Ivor Frischknecht, said that when announced last September the funds had been expected to enable 200 megawatts of new solar capacity, compared with the 240 megawatts already in place.
Instead, the dozen ventures will deliver an extra 480 megawatts if all proceed, and drive $1 billion of investment in regional Australia.
The level of grant funding needed to make the large-scale solar photovoltaic projects had dropped from about half the cost to just 10 per cent in three years, Mr Frischknecht said.

"It's a phenomenal change from the Moree solar farm and AGL's [two plants in NSW], where it was a little less than one commercial dollar for every subsidy dollar," he told Fairfax Media.
The success of ARENA's solar support comes at a critical time for the program's future. The Turnbull government wants to end all grant funding by the agency and strip $1.3 billion from its budget.
Labor, which went to the July election quarantining $300 million of those cuts, may decide as soon as Tuesday's caucus meeting whether it will back the government's omnibus funding through Parliament.
Opponents of the grant cuts say the move would trigger the loss of possibly hundreds of research positions at universities, the CSIRO and elsewhere, and slow advances in renewable energy at a time when Australia has to shift to a low-carbon future.
While large-scale solar costs are about 10 per cent more than wind farms, many other technologies require support to make them less expensive, Mr Frischknecht said. These include large-scale batteries and so-called dispatchable renewables such as solar thermal and bio power that can be switched on and off as needed.
Josh Frydenberg, minister for environment and energy, said the latest round brought federal investment through ARENA to $1.2 billion for around 250 projects, drawing a further $1.6 billion from the private sector.
"ARENA will continue to be a major supporter of renewable energy through the $1 billion Clean Energy Innovation Fund [for concessional loans] which will see new jobs and investment in the sector," Mr Frydenberg said.

Biggest plant
The winners include what will become the country's largest solar farm, with ARENA chipping in $20 million towards the $216.7 million needed to build the 110 MW plant.
That project, to be owned by Origin Energy, will be on Queensland's Darling Downs. (See list of winning projects below.)
The title of largest plant, though, may be up for grabs. Genex's 50 MW Kidston Solar Plant, which has a 20-year supply deal with the Queensland government, has plans to extend to 150 MW.
For NSW, the ARENA-funded projects will support as many as 800 jobs during construction and, when fully operational, will provide enough electricity to power about 62,000 homes or 2,800 schools.
"These five new solar facilities save about 350,000 tonnes of greenhouse gas emissions per year, the equivalent of taking 78,000 cars off the road," Mark Speakman, the state's environment minister, said.

Falling costs
The recent steep drop in large-scale solar costs is mostly from domestic gains, ARENA said.
A falling Australian dollar had largely nullified the drop in global price of imported panels, inverters and other equipment, which typically make up 40 to 50 per cent of total costs, Mr Frischknecht said.
Banks were becoming more comfortable supporting large-scale solar, resulting in cheaper finance, he said, while expanded scale and improved construction process through experience also helped make plants more competitive.
Kellie Caught, a spokeswoman for WWF Australia, said the winning bids amounted to "one billion reasons" for the government to maintain full grant funding.
"ARENA plays a critically important role in building new technologies, reducing the cost of renewable energy, increasing renewable energy supply and diversity in Australia, improving grid stability and reliability, building industry skills, developing export capabilities and creating thousands of jobs," she said.

Open letter
Details of solar's advance came as 11 major energy companies issued an open letter to federal politicians calling on them to protect ARENA's funding.
The companies – which include AGL, General Electric, First Solar, wind turbine maker Vestas, electric car and battery maker Tesla and wind farm operator Infigen Energy – said investment confidence would be undermined in the sector if one of the new Parliament's first moves was to cut ARENA's support.
"The grants provided by the agency are modest investments that will lead to the jobs and investment of the future," Kane Thornton, chief executive of the Clean Energy Council, said.
"Hundreds of projects have been funded to date, and hundreds more are needed if we are to transform Australia's energy system at the lowest possible cost to consumers."
Queensland's Energy Minister, Mark Bailey, said additional support from the Palaszczuk government had helped boost the "competitiveness of so many Queensland projects in the ARENA process".
The backing is in the form of long-term revenue contracts to aid investor confidence.
Mr Frischknecht said the current funding round would be "a litmus test" to determine whether additional rounds would be needed in the future for large-scale solar PV – an outcome that could be known within six to 12 months.

A New Type Of Politics Could Help Prevent Climate Disaster

The Guardian - Andrew Simms
A UK cross-party initiative addresses the appetite and mechanics for the cooperation needed to help us live within Earth's limits

Four months and counting
China and the US's announcement that they will join the Paris climate accord comes at a time when the UK's own climate and energy policies appear at best in disarray, and worst at odds.
Imagine you're stuck in a burning building. Stay and you perish, but the complexity of the building means that to physically escape you have to work with the others also trapped. If everyone does their own thing, many valiant efforts will be made, but ultimately you'll all be doomed.
Tackling climate change is fundamentally a challenge of first accepting that action sufficient to prevent irreversible warming is non-negotiable – you need to get out of the burning building – and then of solidarity and cooperation, you need to make the escape plan happen together.
In the UK only the Green party has climate targets roughly in line with what climate science says is needed. Meanwhile, solidarity and cooperation within parties is proving hard enough to achieve after the vote for the UK to leave the EU, let alone presenting the electorate with an undivided progressive choice in elections.
Post-Brexit we can expect little of the UK government on sufficient and clear climate action. The great irony of the lobby to leave, which railed against the "red tape" of Brussels, is that it has triggered probably Britain's biggest ever open-ended, bureaucratic exercise. Forty years' worth of legislation and cross-border agreements need rewriting in a more complicated, multipolar world. Not only will this distract, decisively, from achieving much else, but international treaty negotiation will be dictated by the old economics of competition and division.
Fortunately, new alliances in the UK are being explored to reverse inequality and live within the Earth's limits.
Caroline Lucas has joined with Lisa Nandy, Labour's former shadow spokesperson on energy and climate change, and Liberal Democrats including the current leader, Tim Farron, to launch an initiative for greater direct political cooperation, called for in a new book, The Alternative: Towards a New Progressive Politics. The title echoes the name of the mould breaking new political party in Denmark of the same name, The Alternative, set up in 2013 to be a fresh, collaborative and progressive voice and change the divisive tone of domestic politics.
Writing in the book, Uffe Elbæk, its party leader, compares the emergence of The Alternative to Syriza and Podemos as a reaction to a failure of the political system so serious that it leaves democracy itself under threat. But, far from strident, their response is to advocate for new, shared values that are the inverse of the emergent chest-beating and fearful nationalism threatening international cooperation on everything, including climate change. They speak instead of political mobilisation based on humility, empathy, courage, generosity and even humour.
The scope and ambition of contributors to the UK initiative addresses the appetite and mechanics for cooperation.
In a chapter on re-imagining Britain's approach to the environment, I argue in the book that from government to anti-austerity groups in opposition, there is a kind of denial about the full economic implications of preventing irreversible climatic upheaval. The clamour for a return to growth inevitably results in a kind of business as usual consumerism.
In terms of alternative economic visions among progressive circles, if any are discernible they tend toward the vague promise of "fully automated luxury communism" - a world in which technology and redistribution deliver lives of leisure and plenty.
But not only does this founder on broken planetary, environmental boundaries, it also contains a kind of impoverished digital disengagement with the real, material world. The alternative is a green, circular and genuinely shared economy of "better not more". In this, reskilled and reconnected, rather than passive, disposable consumerism, we take back more control of our lives making, mending, re-using and sharing more of the things we need.
Not only does this bring greater independence, wellbeing, cost and resource savings, but it draws on long-standing working class traditions of self and mutual help that let people and communities flourish in tough economic times. The cultivation of new skills and craft also counter the alienation of much modern work.
A new more plural, progressive politics, capable of supporting the changes needed to prevent climate disaster, itself needs a new economic model, judged not by how quickly it grows, but by how well it allows us all to thrive within planetary environmental boundaries.

Prime Minister Malcolm Turnbull Tackles Climate Change, Disaster Mitigation At ASEAN Summit

NEWS.com.au - Tory Shepherd

THERE is “no more pressing need” in the region than climate change, Prime Minister Malcolm Turnbull has told Pacific leaders in Micronesia.
Mr Turnbull announced $300 million to help the Pacific “manage climate change and improve disaster resilience”.
The Prime Minister landed in Pohnpei on Friday for his third round of regional talks — having visited Hangzhou in China for the G20 and Vientiane in Laos for the Association of Southeast Asian Nations (ASEAN) summit.
“Over the next four years we’ll provide $300 million to Pacific island countries including $75 million for disaster preparedness. This is an additional $80 million on the current levels,” he said.
Mr Turnbull also said Australia would ratify the Paris climate change agreement this year or early next year.
“We will ratify it as soon as parliamentary processes allow ... Its ratification is not controversial,” he told the Pacific Island Forum in Pohnpei.
Earlier Mr Turnbull met with Federated States of Micronesia Peter Christian; Mr Christian said he was ashamed Micronesia did not have an embassy in Australia and that he would like to find “a little building somewhere in Canberra”.
The two also discussed the Pacific patrol vessels Australia will build, which will replace the existing boats used to stop illegal fishing in the area, for search and rescue, and for national security.
Held in the backdrop of green hills, blue water and palm trees, Mr Turnbull looked decidedly relaxed as he sported a green and blue leaf motif shirt at the 47th Pacific Islands Forum — themed ‘Small and Far: Challenge for Growth”.
Speaking in the lead-up to the forum, FSM Vice President Yosiwo George said due to the distance and smallness of forum countries they face transportation, economic growth and development and foreign investment barriers. “Many of our economies have the same characteristics: low productivity, low growth, and an inefficient public sector involvement in job creation,” he said.
How to solve these issues as well as grappling with the increasing threat of climate change and disaster mitigation will top the forum’s agenda.
According to the World Bank, FSM already incurs, on average, $US8.8 million ($A11.5 million) per year (about 3.1 per of GDP) in losses due to typhoons, earthquakes and tsunamis.
Climate change will only increase this vulnerability — resulting in more intense typhoons, sea level rises storm surges, floods and droughts — adversely impacting agriculture, fisheries, coastal zones and water resources.

On  the opening day of the forum on Thursday, Papua New Guinea Prime Minister Peter O’Neill heralded the recent commitment by the United States and China to ratify the Paris Agreement — something Australia aims to do by the end of the year.
“We must continue to show leadership and encourage all countries to ratify the agreement,” Mr O’Neill added.
In a report released earlier this week, Oxfam Australia said Australia was not doing enough in the Pacific to help them battle the effects of climate change and called on the government to commit $A3.2 billion by 2020.
Mr Turnbull has already flagged that he will be announcing a “substantial” assistance package at the forum, but details are yet to be released. Australia will also be giving up to 21 patrol boats to Pacific Island countries to promote air surveillance to monitor illegal maritime activities.
On Thursday Mr Turnbull’s invitation to South-East Asian leaders to attend a special meeting in Australia has been enthusiastically received.
Mr Turnbull invited leaders to a special Australia-ASEAN summit in 2018.
“That invitation has been received with great enthusiasm and we look forward to that as another building block in this already very strong relationship,” he told reporters in Vientiane on Thursday.

Morale Falling, Staff Optimism About CSIRO Future Low, Survey Shows

ABC News - Jake Sturmer

Morale is falling among CSIRO workers and staff optimism about the future of the research organisation is low, according to a staff survey.
The survey commissioned by the organisation also reveals a massive disconnect between the organisation's management and its staff overall.
It comes as the organisation prepares to axe hundreds of jobs, largely in the oceans, atmosphere, land and water climate science teams.
The survey found 97 per cent of the leadership team believed in the next year CSIRO would change for the better — compared to just 21 per cent of staff who shared that view.
Staff at CSIRO are half as optimistic for the future compared to other organisations in Australia and similar research institutions around the world.
More than 3400, or around 64 per cent of staff, participated in the survey in July this year.
It sets out the scale of the task at hand for chief executive Larry Marshall, who has just had his contract renewed by the board until the end of the decade.
"Dr Marshall has our support to continue to implement [the] Strategy 2020," CSIRO chairman David Thodey said in an email to staff.
Optimism at the CSIRO is low compared to similar organisations around the world. (CSIRO)
In another report released today, a review of the decision-making processes that led to the controversial job cuts by consultants Ernst and Young found oversights in governance and risk management.
It found consistent problems in the way management handled the cuts, known internally as the Science Prioritisation and Implementation (SPI) process.
The review recommends CSIRO "reassess the existing organisational structure and practices … to provide appropriate management and coordination to all phases of the SPI process".
"The lack of proper planning and assignment of responsibility of each phase of the SPI process … led to perceived levels of inadequacy in rigour and consistency of Executive Team decisions," the consultant's report found.
"There was also limited documentation of the role each of these key stakeholders had to play; when they should be involved; or how they should coordinate activity.
"There was found to be a lack of rigour and protocols regarding the documentation of key meetings and decisions."
CSIRO said in its initial response to the review that by the end of the year, the chief executive would "continue to assess the appropriateness of the current organisation structure and practices and implement changes accordingly".

Obama On Climate Change: The Trends Are ‘Terrifying’

New York Times - Julie Hirschfeld Davis | Mark Landler | Coral Davenport

MIDWAY ATOLL — Seventy-four years ago, a naval battle off this remote spit of land in the middle of the Pacific Ocean changed the course of World War II. Last week, President Obama flew here to swim with Hawaiian monk seals and draw attention to a quieter war — one he has waged against rising seas, freakish storms, deadly droughts and other symptoms of a planet choking on its own fumes.
Bombs may not be falling. The sound of gunfire does not concentrate the mind. What Mr. Obama has seen instead are the charts and graphs of a warming planet. "And they're terrifying," he said in a recent interview in Honolulu.
"What makes climate change difficult is that it is not an instantaneous catastrophic event," he said. "It's a slow-moving issue that, on a day-to-day basis, people don't experience and don't see."

In an exclusive interview on his legacy, President Obama speaks to The Times's Mark Landler and Coral Davenport on climate change while visiting Marine Corps Base Hawaii. Photo by A.J. Chavar/The New York Times.

Climate change, Mr. Obama often says, is the greatest long-term threat facing the world, as well as a danger already manifesting itself as droughts, storms, heat waves and flooding. More than health care, more than righting a sinking economic ship, more than the historic first of an African-American president, he believes that his efforts to slow the warming of the planet will be the most consequential legacy of his presidency.
During his seven and a half years in office, Mr. Obama said, a majority of Americans have come to believe "that climate change is real, that it's important and we should do something about it." He enacted rules to cut planet-heating emissions across much of the United States economy, from cars to coal plants. He was a central broker of the Paris climate agreement, the first accord committing nearly every country to reducing greenhouse gas emissions.

But while climate change has played to Mr. Obama's highest ideals — critics would call them messianic impulses — it has also exposed his weaknesses, namely an inability to forge consensus, even within his own party, on a problem that demands a bipartisan response.
He acknowledged that his rallying cry to save the planet had not galvanized Americans. He has been harshly criticized for policies that objectors see as abuses of executive power and far too burdensome for the economy.
That has made Mr. Obama's record on climate curiously contradictory, marked by historic achievements abroad and frustrating setbacks at home. The threat of global warming inspired Mr. Obama to conduct some of the most masterful diplomacy of his presidency, which has bound the United States into a web of agreements and obligations overseas. Yet his determination to act alone inflamed his opponents, helped polarize the debate on climate change and will carry a significant economic cost.
Mr. Obama chalks up the contradictions both to politics and to the amorphous, unseen nature of the threat.
"It feels like, 'Meh, we can put this off a little bit,'" he said.
The president spoke in a cottage on a Marine base that overlooks Kaneohe Bay in his home state, Hawaii. Angry waves crashed on the rocks below the house, the sea churned by one of two hurricanes spinning close to the island. Hawaii, as one of Mr. Obama's climate advisers pointed out, normally does not get back-to-back hurricanes.
"When you see severe environmental strains of one sort or another on cultures, on civilizations, on nations, the byproducts of that are unpredictable and can be very dangerous," Mr. Obama said. "If the current projections, the current trend lines on a warming planet continue, it is certainly going to be enormously disruptive worldwide."

'All Bets Are Off'
Eight years ago, when Mr. Obama ran for president against Senator John McCain of Arizona, both men had essentially the same position on global warming: It is caused by humans, and Congress should enact legislation to cap greenhouse gas emissions and force polluters to buy and trade permits that would slowly lower overall emissions of climate-warming gases.
But in the summer of 2010, a cap-and-trade bill Mr. Obama had tried to push through Congress failed, blocked by senators from both parties.
"One would have hoped for transformational leadership, in the way J.F.K. would have done it," said Hans Joachim Schellnhuber, the director of the Potsdam Institute for Climate Impact Research in Germany.

That domestic defeat was compounded by failure on the world stage after efforts to enact a highly anticipated United Nations climate change treaty in Copenhagen fell apart in 2009.
By the fall of 2010, Tea Party "super PACs" supported by the billionaire brothers Charles G. and David H. Koch had seized on cap-and-trade as a political weapon, with attacks that helped Republicans take control of the House.
Polls showed that few Americans thought of climate change as a high public policy priority, and the percentage of voters who accepted the reality that it was caused by humans had tumbled.
"There is the notion that there's something I might have done that would prevent Republicans to deny climate change," Mr. Obama said. "I guess hypothetically, maybe there was some trick up my sleeve that would have cast a spell on the Republican caucus and changed their minds."
In fact, some Republicans, including Senator Lamar Alexander of Tennessee, were willing to go forward with a more limited climate bill that would have restricted emissions only from power plants. But the president's own party would not unify even around that, with Democrats from industrial and coal states digging in against him. Ironically, Mr. Obama would end up with regulations that narrowly target power plant emissions.
"The White House wanted 60 votes on climate, and they weren't interested in Republican votes," Mr. Alexander said in an interview. "Now it's back to power plant only. The lesson here is that if people who want a result would be a little bit more flexible, they might actually get one."
In defeat, the president appeared cowed. Campaigning against Mitt Romney in 2012, he barely mentioned climate change.
But soon after Election Day, Mr. Obama interrupted a broad discussion with historians about the country's challenges with a surprising assertion. Douglas Brinkley, a historian who attended the session, recalled, "Out of nowhere, he said, 'If we don't do anything on the climate issue, all bets are off.'"
Mr. Obama, who understood that a legislative push would be fruitless, told his advisers to figure out how to enact deep emissions cuts without Congress. They found a way through the Clean Air Act of 1970, which gives the Environmental Protection Agency the authority to issue regulations on dangerous pollutants.
In 2014, Mr. Obama unveiled the first draft of what would become the Clean Power Plan: a set of Clean Air Act rules that could lead to the closing of hundreds of coal-fired power plants.
The move enraged critics, including Senator Mitch McConnell of Kentucky, the majority leader, whose state relies heavily on coal.
Another critic, Laurence H. Tribe, likened the rules to "burning the Constitution" — a charge that might have stung, since Mr. Tribe, a liberal constitutional scholar, was a mentor to Mr. Obama at Harvard Law School.
Mr. Obama dismissed the criticism as the voice of Mr. Tribe's client, Peabody Energy, the nation's largest coal company, which filed for bankruptcy protection in April. "You know, I love Larry," he said, but "when it comes to energy issues, Larry has a history of representing fossil fuel industries in big litigation cases."
The legality of the climate rules is likely to be decided by the Supreme Court, the composition of which depends on the outcome of the presidential election. Deep-pocketed corporations will not give up the legal fight easily, even after a Supreme Court decision, and Republicans in Congress will continue their legislative attacks. If the rules survive, they will almost certainly cost the coal industry thousands of jobs.
"What we owe the remaining people who are making a living mining coal is to be honest with them," Mr. Obama said, "and to say that, look, the economy is shifting. How we use energy is shifting. That's going to be true here, but it's also going to be true internationally."

Scrutinizing the Science
Few people would have described Mr. Obama as a climate evangelist when he ran for the White House in 2008. While he invoked the rising seas and heating planet to thrill his young supporters, he did not have the long record of climate activism of Al Gore or John Kerry, who is now his secretary of state. Like many things with Mr. Obama, his evolution on climate was essentially an intellectual journey.
Mr. Obama immersed himself in the scientific literature, which left little doubt that the planet was warming at an accelerating rate. "My top science adviser, John Holdren, periodically will issue some chart or report or graph in the morning meetings," he said, "and they're terrifying."

The morning Mr. Obama unveiled the final version of the Clean Power Plan last year, he summoned his senior climate adviser, Brian Deese, to the Oval Office. Mr. Deese expected that the president would hand him some last-minute changes to his speech. Instead, he brought up an article in the journal Science on melting permafrost.
The research not only documented faster increases in temperatures, but also drew direct links between fossil fuel emissions and extreme weather.
Mr. Obama scrutinized reports like the 2014 National Climate Assessment, which tied climate change to events like flooding in Miami and longer, hotter heat waves in the Southwest.
"More and more, there are events that are happening that are astoundingly unusual, that knock your socks off, like the flooding in Louisiana," said Michael Oppenheimer, a professor of geosciences and international affairs at Princeton University. "Those are the kinds of events where it's becoming possible to draw attribution."
Benjamin J. Rhodes, one of the president's closest aides, recalled Mr. Obama talking about "Collapse: How Societies Choose to Fail or Succeed," Jared Diamond's 2005 best seller, which explored the environmental changes that wiped out ancient societies like Easter Island and discussed how modern equivalents like climate change and overpopulation could yield the same destruction.
The president's Pacific roots also came into play. In Honolulu last week, he told a meeting of Pacific Island leaders that few people understood the stakes of climate change better than residents of their part of the planet. Crops are withering in the Marshall Islands, he noted. Kiribati is buying property in another country for the day that its own land vanishes beneath the waves. And villagers in Fiji have been forced from their homes by high seas.
Shifting monsoon patterns in South Asia could affect a billion people who depend on low-lying agriculture, Mr. Obama said in his interview.
"If you have even a portion of those billion people displaced," he said, "you now have the sorts of refugee crises and potential conflicts that we haven't seen in our lifetimes."
"That," he added, "promises to make life a lot more difficult for our children and grandchildren."

Joining Forces With China
Mr. Obama and Hillary Clinton never seem to tire of telling the story of Copenhagen: In December 2009, with the climate conference on the verge of failure, the two learned of a meeting of the leaders of Brazil, China, India and South Africa, from which they had been pointedly excluded. Elbowing their way past a Chinese security guard, they crashed the meeting, and over the course of 90 minutes of tense negotiations with the abashed leaders, they extracted an agreement to set goals for lowering emissions.
The Europeans, who had been cut out of the talks, derided the deal as toothless, but Mr. Obama learned from the experience. A global climate accord could not simply be a compact among developed economies, he said. It had to include the major developing economies, even if they resented being held to standards that had never applied to the club of wealthy nations. And any agreement had to be led by the two largest emitters, the United States and China.
Mr. Obama set about persuading President Xi Jinping of China to join the United States in setting ambitious reduction targets for carbon emissions. Tensions were already high over China's hacking of American companies, and the United States was balking at China's slow-motion colonization of the South China Sea. A casual, get-acquainted summit meeting between Mr. Obama and Mr. Xi at the Sunnylands estate in California in June 2013 had failed to break the ice.

But the meeting did produce one headline: an agreement to explore ways to reduce emissions of hydrofluorocarbons, known as HFCs, potent planet-warming chemicals found in refrigerants. In hindsight, it would prove significant. The final international accord on the chemicals is expected to be ratified next month in Rwanda.
"It was a place Obama and Xi found some common ground," said John D. Podesta, a chief of staff to President Bill Clinton whom Mr. Obama recruited to lead his climate efforts in his second term. (Mr. Podesta is now the chairman of Mrs. Clinton's presidential campaign.)
Mr. Podesta and Todd Stern, the State Department's climate envoy, began arduous negotiations with China. They were backed by Mr. Kerry and Mr. Obama, who sent Mr. Xi a letter with a proposal in which the United States would pledge to increase its target for reducing carbon emissions by 2025 if the Chinese pledged to cap and then gradually reduce their emissions.
China had historically resisted such agreements, but the air pollution there had become so bad, Mr. Obama noted, that the most-visited Twitter page in China was the daily air-quality monitor maintained by the United States Embassy in Beijing.
"One of the reasons I think that China was prepared to go further than it had been prepared to go previously," Mr. Obama said, "is that their overriding concern tends to be political stability. Interestingly, one of their greatest political vulnerabilities is the environment. People who go to Beijing know that it can be hard to breathe."
The Chinese were also swayed by Mr. Obama's announcement in 2014 of his regulations to reduce emissions from coal-fired power plants, which gave Mr. Kerry and his team of climate diplomats the leverage they needed in months of meetings with China. On Nov. 11, 2014, after a quiet stroll across a bridge in the Chinese leadership compound beside the Forbidden City, Mr. Xi and Mr. Obama sealed their agreement.
"By locking in China," Mr. Obama said, "it now allowed me to go to India and South Africa and Brazil and others and say to them: 'Look, we don't expect countries with big poverty rates and relatively low per-capita carbon emissions to do exactly the same thing that the United States or Germany or other advanced countries are doing. But you've got to do something.'"
A little more than a year later, in Paris, the United States led negotiations among 195 countries that resulted in the most significant climate change agreement in history. And this past weekend in Hangzhou, China, Mr. Obama and Mr. Xi formally committed their two nations to the Paris accord. For Mr. Obama, it was not just redemption for Copenhagen, but a vindication of his theory of the United States' role in the world.
"There are certain things that the United States can do by itself," Mr. Obama said. "But if we're going to actually solve a problem, then our most important role is as a leader, vision setter and convener."

An Ambitious, Divisive Legacy
To his successor, Mr. Obama leaves an ambitious and divisive legacy: a raft of new emissions rules that promise to transform the United States economy but are likely to draw continuing fire from Republicans, and an aggressive — some say unrealistic — pledge made in Paris to reduce greenhouse gas emissions 80 percent from 2005 levels by 2050.

All of this, he acknowledges, could be undone at the ballot box. "I think it's fair to say that if Donald Trump is elected, for example, you have a pretty big shift now with how the E.P.A. operates," he said.
Mrs. Clinton has embraced Mr. Obama's go-it-alone approach, promising to meet and in some cases exceed his goals without trying to pass cap-and-trade legislation. She is proposing marquee projects like installing 500 million solar panels by 2020 and giving states and cities $60 billion to invest in energy-efficient public transportation and buildings.
"It will be first-order business," Mr. Podesta said.
But Mrs. Clinton will face the same partisan fire Mr. Obama has. He noted that, like him, Mrs. Clinton had been pilloried in coal country for acknowledging that coal mining would have a declining role in a 21st-century economy. Mr. Obama's bet is that as his regulations get woven into the fabric of the economy, they will be harder for anyone to unwind. He says that his successor should promote past victories, including those of Republicans like Richard M. Nixon and George Bush.
For his part, Mr. Obama said he planned to stay active in fighting climate change in his post-presidential life. During his tour of the wildlife on Midway, he paused to make an improbable remark.
"My hope," he said, "is that maybe as ex-president I can have a little more influence on some of my Republican friends, who I think up until now have been resistant to the science."
