Key points
  • Hottest winter since records began in 1910
  • Ninth driest winter on record
  • More high pressure systems prevented rain
Winter in Australia this year was hot and dry with the average maximum temperature up nearly 2 degrees Celsius above the long-term trend.
The 2017 winter was the hottest since 1910 when national records began, according to Bureau of Meteorology figures released today.
The average maximum daily temperature recorded across all Australian recording locations for June, July and August 2017 was 23.7C.
That is a whopping 1.9C degrees above the baseline 1961 to 1990 average of 21.8C and smashes the previous record of 23.4C set in 2009.

The warm weather was most pronounced in the north of Australia.
It was the hottest winter on record for Western Australia, Queensland and the Northern Territory, while New South Wales and South Australia made the top three.
Daily minimums were also warmer than average in most of northern Australia but not as far above average as the maximums.
In contrast, inland NSW and northern Victoria had notably cold nights with many areas 1C to 2C below average.

Meanwhile nationally it was the ninth driest winter on record. The only large area to record rainfalls significantly above average was a pocket of central NT as a result of one rain event in mid-July.

Skies stay clear
Andrew Watkins, manager of extended and long-range forecasts at the Bureau of Meteorology, said the real reason for the warmth was the persistent high pressure seen particularly during early winter.
"But you also have to add to that the long-term warming trend," he said.
"The higher than average pressure has kept the skies clear and rain away — meaning more heating of the inland from the sun and less evaporative cooling from ample water on the ground."

Evaporative cooling is the same process that cools you down when you sweat, taking energy from the surrounding air to convert liquid water into gaseous water vapour, leaving the surroundings cooler.
Without a lot of water on the ground this year, large scale evaporative cooling could not happen.
The clear skies also explain the low minimum or overnight temperatures in the southern states.
Without a blanket of clouds, the heat from the day is lost to space, and temperatures drop overnight.

High pressure prevented cold fronts
But that is not all, Dr Watkins said: "We've also seen fewer cold fronts able to penetrate inland due to the slow moving and more southerly highs acting as a barrier to their normal northward progression".
So not only has high-pressure prevented rain in the north but it has also prevented the cold fronts which normally bring rain in the south during winter.
According to the climate scientists at the Bureau of Meteorology, the story behind the heat in northern Australia is more about what has not been happening.
In a standard winter there would be several south-easterly surges, bringing cold air into the tropics.
This year these surges were almost completely missing — blocked by that high pressure — until very late in the season.

So was the hot weather predicted?
The short answer is yes. The Bureau of Meteorology's 2017 winter outlook released in May, showed a high chance of exceeding median maximum temperatures.
Going into winter, high pressure conditions were likely.

"Our reasoning back at the time was that despite neutral ENSO and IOD patterns, the Pacific and Indian oceans were warmer than average, with cooler conditions in the eastern Indian Ocean near WA," Dr Watkins said.
Warm ocean temperatures are an indication of the energy available to the system, while cool temperatures in the eastern Indian Ocean would prevent the lift required to mix up and break down a growing region of high pressure.

What about the long-term warming trend?
Nineteen of the last 20 winters have now had average maximum daily temperatures above the 1961 to 1990 average.
Andrew King, climate extremes research fellow from the University of Melbourne, uses a range of computer climate models created all over the world to tease out the different factors causing extreme weather events.
His analysis of the factors behind this winter's record heat showed that the influence of climate change increased the likelihood of this winter's record warmth by at least sixty-fold.
Dr King said a very clear human influence could be seen in Australia's winter.

Spring outlook
According to BoM's new spring outlook released yesterday, it looks like spring is going to continue to be warmer than average for the north and southeast of the country.
While rainfall will be below average for south-west WA, it will be above average for south-east Queensland and far-east Gippsland.
No matter what comes in spring, winter 2017 is one for the record books.

States Leave Federal Government In The Shade When It Comes To Renewables: Report

Fairfax - Peter Hannam

NSW has the most large-scale renewable energy projects under way in Australia, and lifted its share of clean energy markedly in the past year, as states and territories take the lead in decarbonising the electricity sector, a report by the Climate Council has found.
A jump in hydropower helped raise renewable energy share in NSW by 5 percentage points last year to 17 per cent. That was marginally above the national share of 16 per cent, and the second-biggest increase after South Australia.


Which is Australia's most renewable state?
With states taking the lead in the renewable energy push, a report by the Climate Council puts each state's efforts against one another.

The Climate Council, though, rated by the most populous state behind all but Western Australia and the Northern Territory. While NSW has a net-zero economy-wide emissions target for 2050, it has not set a goal for renewables.
By contrast, Victoria gained credit for its efforts to legislate this year a 25 per cent renewable energy share by 2020 and 40 per cent by 2025. Last year, the state's share was 12 per cent, up one percentage point from 2015.

Overall, efforts by states and territories are ahead of the federal government, which continues to dither over whether to set a Clean Energy Target as proposed by Chief Scientist Alan Finkel. The current Renewable Energy Target (RET), to achieve 33,000 gigawatt-hours a year, only runs until 2020.
"Almost all states and territories (except Western Australia) now have higher renewable energy targets or net-zero emissions targets which are stronger than the federal government," according to the council's Renewables Ready: States Leading the Charge report.
The Turnbull government "has not implemented any new policies to support renewable energy investment beyond measures in place before [it] took office" in 2013, it said. The government, though, had taken "some positive steps" to support energy storage schemes, such as the so-called Snowy 2.0 plans to boost capacity of the Snowy Hydro scheme.

Energy issues remain a hot political issue, with Prime Minister Malcolm Turnbull on Wednesday telling the heads of major electricity and gas firms to help consumers cut their soaring power and gas bills by highlighting the best deals on offer.
About 3 gigawatts of new renewable energy will be under construction in Australia this year.
Big electricity retailers pledged to contact at least 1 million customers currently on default offers to explain how they might get lower tariffs. Longer term cost cuts, though, would depend on "policy certainty and new investment in generation", Matthew Warren, chief executive of the Australian Energy Council, said.
New wind and solar farms, underpinned by the RET, and new rooftop solars are almost the only new capacity being added to the grid.
In terms of large-scale projects, NSW will build eight ventures this year with a 1.018 gigawatts of capacity, roughly a third of the national total, the Climate Council report notes. Queensland is next largest, with 784 megawatts and Victoria third with 687 megawatts.
By comparison, Australia added 265 megawatts of large-scale capacity in 2016 as the sector began its recovery from an investment drought during the Abbott government years.
Among the states, Tasmania last year generated 92 per cent of its electricity from renewables – down from 99 per cent in 2015. South Australia last year lifted its renewable energy share by 7 percentage points to 47 per cent, a ratio lifted in part by the closure of an ageing coal-fired power station.
Rooftop solar, meanwhile, has now reached about 21 per cent of households, or 1.7 million homes, the council's report said.
Queensland appears to be living up to its one-time moniker as the sunshine state, with 31.6 per cent of homes having solar photovoltaics as of April. South Australia trails with 30.5 per cent, and WA 25.4 per cent.
NSW has the second-most installed rooftop panel capacity, at 1.413 gigawatts, behind Queensland's 1.727 gigawatts. Victoria has the third largest capacity at 1.048 gigawatts, the reports said.

Coalition Watering Down Finkel Review Climate Ambitions

The Guardian

Exclusive: Draft implementation plan lacks electricity emissions trajectory, Paris agreement alignment and low-income subsidies

The climate ambitions of the Finkel review appear to be being watered down by the government as it is implemented, according to a draft Coag Energy Council implementation strategy obtained by the Guardian.
The draft implementation plan removes a key recommendation for an agreed emissions trajectory for the electricity system, alignment with the Paris agreement and subsidised solar and batteries for low-income houses.
Sources tell the Guardian the document was prepared by the federal government and distributed to state and territory representatives on the morning of the meeting, leaving little time for state representatives to analyse it.
A final version of the document is expected to be delivered to Coag today.
The federal environment and energy minister, Josh Frydenberg, declined to comment on the document, saying: “It is not appropriate for any government to comment on draft documents of the Council of Australian Governments.”
Described by the prime minister, Malcolm Turnbull, as a “blueprint for the once-in-a-century transformation currently taking placing in Australia’s energy system”, the Finkel review presented 50 recommendations to the Council of Australian Governments (Coag).
Those recommendations were intended to solve the energy “trilemma” – delivering affordable and reliable electricity, while lowering emissions.
The review itself was widely criticised for lacking in ambition when it came to action on climate change, and failing to align with Australia’s commitments made in the Paris climate agreement.
The key recommendation of the review was a clean energy target, which Frydenberg has so far failed to get approved by the joint Coalition party room, which includes a number of climate change deniers.
But the party room agreed to the other 49 recommendations, which the Coag Energy Council is now advising heads of government on how to implement.
At a teleconference on Friday last week, state and territory energy ministers were presented with a draft implementation plan for discussion.
That document, obtained by the Guardian, appears to water down those recommendations in relation to climate change, and removes some altogether.
One key recommendation in the Finkel review that has been severely weakened in the draft implementation document is a change that would force the electricity market to align efforts to meet government emissions reduction commitments made as part of the Paris agreement.
Finkel’s recommendation said Coag leaders should agree to a new Australian Energy Market Agreement, which commits all parties to “a nationally consistent approach to energy policy that recognises Australia’s commitment in Paris to reduce emissions and governments’ commitment to align efforts to meet this target with energy market frameworks.”
But the draft implementation document removes the reference to international emissions reduction commitments, instead saying merely that the agreement will “reaffirm Australian governments’ commitment to the [national electricity market] and a national, integrated approach to energy and emissions reduction policy”.
Among Finkel’s key recommendation for an “orderly transition”, he called for three things: the clean energy target; a three-year notice of closure for existing large generators; and “an agreed emissions reduction trajectory”. All three moves were part of one recommendation, numbered 3.2.
The Coalition has not agreed to adopt the clean energy target but it has agreed to the three-year notice-of-closure rule, which appears in the implementation plan. However, the plan does not contain any mention of an agreed emissions reduction trajectory.
Frydenberg told the Guardian his view is that the Coag Energy Council did not agree to the emissions reduction trajectory because it is part of the clean energy target.
“The Coag Energy Council has agreed to implement the recommendations of the Finkel review except for the clean energy target, which includes the national electricity market emissions trajectory which the federal government is currently considering.”
It is unclear why the emissions trajectory is considered part of the clean energy target, since the Finkel review makes clear that there are a number of mechanisms that could achieve such a trajectory. Finkel modelled several such mechanisms, including an emissions intensity scheme.
Another Finkel recommendation calls for low-income households to be given subsidised access to “energy efficient appliances, rooftop solar photovoltaic and battery storage systems”.
Explicit references to renewable energy has been removed in the draft implementation plan and replaced with “energy efficiency and demand management technologies”.
Sources say representatives of the ACT raised the question of the trajectory being removed, and asked for it to be included. Representatives of Queensland and Victoria also apparently raised concerns about some of the other changes.
Sources said the document, which was prepared by the federal government, was circulated to state energy ministers only hours before the meeting was held, leaving little time for proper scrutiny.
The document is expected to be finalised and sent to heads of government today.

Arctic Sea Ice Outlook At Worst Point In 125,000 Years

CosmosAndrew Masterson

Though temperatures were warmer during the last interglacial period, the greenhouse effect of atmospheric C02 is now melting more Arctic sea ice.

The prognosis for summer Arctic sea-ice loss over the next few decades is worse than it was 125,000 years ago during the last interglacial period, despite the fact temperatures were higher then.
That is the sobering conclusion reached by researchers at the Alfred-Wegener Institute in Germany. Their findings are published in the journal Nature Communications.
A team led by paleoclimatologist Rüdiger Stein combined sediment core data and climate models to estimate historical ice levels in the Arctic Ocean, in light of evidence-weighted predictions that such ice may disappear during the northern summer in the next 50 to 100 years.
Even though “the high latitudes were significantly warmer than today” during the interglacial period, the scientists state, “sea ice existed in the central Arctic Ocean during summer”.
The key climatic difference between then and now, they found, was the amount of carbon dioxide in the atmosphere. Sediment cores revealed that during the interglacial period, atmospheric CO2 levels were about 290 parts per million (ppm). Now the level is about 400 ppm.
Modelling used by the Intergovernmental Panel on Climate Change predicts CO2 levels will increase to 500 ppm over the next few decades. Plugging these values into their models, Stein and colleagues predict sea ice in the central zone of the Arctic Ocean will decline rapidly over the next several decades and disappear completely in about 250 years.
Rising CO2 levels add layers of complexity to Arctic climate models because it alters the feedback mechanisms that operate between ice, sunlight and seawater.
Wide, thick ice sheets reduce the biological fecundity of the waters beneath them but also have a strong albedo effect – reflecting sunlight back into atmosphere and thus limiting the energy absorbed by the ocean.
As CO2 levels increase, the ice sheets become less robust, shrinking and thinning. The albedo effect is proportionately reduced, potentially boosting ocean biomass through increasing light and heat.
The researchers write that sea ice, because it is involved in several key climate feedbacks including ice-albedo feedback and cloud-radiation feedback, “plays a substantial role in the global climate system variability, known as polar amplification”.
To assess sea-ice thickness more than 100,000 years ago, Stein and his team used biomarkers – specifically, signatures of a species of algae that exists beneath moderate sea ice sheets.
The absence of algal traces at points in the sediment cores is clear evidence of periods when the ice sheet was too thick for the species to inhabit the location.
The researchers concede their modeling and the ice core evidence contain inconsistencies that limit the predictive power of their findings. However, they term the paper an “important groundtruthing” exercise. They call for more detailed data and more sophisticated models that examine, in particular, “external forcings and related internal feedback mechanisms” to further improve results.

We Can No Longer Tolerate Climate Change Denial

Sydney Morning Herald -  Editorial

The United States Weather Service, normally not an agency prone to colourful language, issued an extraordinary statement on Sunday regarding hurricane Harvey, saying, "This event is unprecedented and all impacts are unknown beyond anything experienced".
It is now predicted the storm could eventually drop over 150 centimetres of rain in some areas, more than any other in the region's history.
Far from over, it is already clear that Harvey's impact is catastrophic. Six people are confirmed dead and that number is expected to increase. Cost estimates range up to $US100 billion.
America's efforts to combat climate change have been battered by President Donald Trump. Photo: AP
Meanwhile flooding in Bangladesh, India and Nepal during the region's worst monsoon season in a decade has killed an estimated 1200 people.
Climate scientists are reluctant to attribute any particular weather event to global warming, though in this case the signs are that human behaviour contributed to the formation and severity of the storm and its impact.
As tropical storm Harvey moved towards the Texas coast last week, few models predicted it would intensify into such a damaging weather system. It then hit an ocean patch in the Gulf of Mexico that remained so hot over the northern winter that it broke temperature records on one in four days according to Houston meteorologist Matt Lanza.
On the day Harvey hit, the area was around 2.2 degrees hotter than normal. Fuelled by the aberrant water temperature Harvey grew rapidly into a category-four cyclone as it hit the coast. It is now trapped in place over Houston, constantly siphoning energy and moisture from an ocean that scientists agree is likely to have been warmed by climate change.
The flooding across America's fourth-largest city was predicted last year in a joint investigation by the Texas Tribune and the non-profit investigative journalism organisation ProPublica.
"As millions have flocked to the metropolitan area in recent decades, local officials have largely rejected stricter building regulations, allowing developers to pave over acres of prairie land that once absorbed large amounts of rainwater. In the decade after Tropical Storm Allison [in 2001], about 167,000 acres were developed in Harris County, home to Houston," ProPublica wrote last week when it revisited its earlier investigation.
America's efforts to combat climate change and set policy to live with its impact have been battered by President Donald Trump, who formally notified the United Nations of his decision to withdraw from the Paris climate agreement earlier this month.
Last month Mr Trump rescinded Obama-era regulations that would have made urban development and infrastructure more flood resilient in future.
Mr Trump's Environmental Protection Agency director, Scott Pruitt, has made the dismantling of his agency's effort to combat climate change the central goal of his tenure, and in April the EPA scrapped its climate website entirely.
Australia risks following America's lead on climate change.
Efforts to craft national energy policy that reflect the realities of climate change and rapidly advancing renewable energy technology are blocked by a hardline faction of the coalition partyroom led by former prime minister, Tony Abbott.
In February last year CSIRO announced massive funding cuts to its climate change research division, only to partially overturn the decision in the face of sustained national and international criticism. This year the government ended all funding for the National Climate Change Adaptation Research Facility.
As with America's, Australia's ongoing failure to deal with climate change carries practical and moral consequence. We cannot significantly cut our greenhouse gas emissions without determined national effort and we cannot engage our diplomatic expertise and might to contribute more to an international solution until we cut our emissions.
We cannot any longer afford to tolerate the scientific myopia exemplified by Mr Trump and Mr Abbott.

Harvey Didn’t Come Out Of The Blue. Now Is The Time To Talk About Climate Change.

The Intercept

Evacuees wade down a flooded section of Interstate 610 as floodwaters from Tropical Storm Harvey rise in Houston on Sunday, Aug. 27, 2017.
Now is exactly the time to talk about climate change, and all the other systemic injustices — from racial profiling to economic austerity — that turn disasters like Harvey into human catastrophes.
Turn on the coverage of the Hurricane Harvey and the Houston flooding and you’ll hear lots of talk about how unprecedented this kind of rainfall is. How no one saw it coming, so no one could adequately prepare.
What you will hear very little about is why these kind of unprecedented, record-breaking weather events are happening with such regularity that “record-breaking” has become a meteorological cliche. In other words, you won’t hear much, if any, talk about climate change.
This, we are told, is out of a desire not to “politicize” a still unfolding human tragedy, which is an understandable impulse. But here’s the thing: every time we act as if an unprecedented weather event is hitting us out of the blue, as some sort of Act of God that no one foresaw, reporters are making a highly political decision. It’s a decision to spare feelings and avoid controversy at the expense of telling the truth, however difficult. Because the truth is that these events have long been predicted by climate scientists. Warmer oceans throw up more powerful storms. Higher sea levels mean those storms surge into places they never reached before. Hotter weather leads to extremes of precipitation: long dry periods interrupted by massive snow or rain dumps, rather than the steadier predictable patterns most of us grew up with.
The records being broken year after year — whether for drought, storm surges, wildfires, or just heat — are happening because the planet is markedly warmer than it has been since record-keeping began. Covering events like Harvey while ignoring those facts, failing to provide a platform to climate scientists who can make them plain, all while never mentioning President Donald Trump’s decision to withdraw from the Paris climate accords, fails in the most basic duty of journalism: to provide important facts and relevant context. It leaves the public with the false impression that these are disasters without root causes, which also means that nothing could have been done to prevent them (and that nothing can be done now to prevent them from getting much worse in the future).
It’s also worth noting that the Harvey coverage has been highly political since well before the storm made landfall. There has been endless talk about whether Trump was taking the storm seriously enough, endless speculation about whether this hurricane will be his “Katrina moment” and a great deal of (fair) point-scoring about how many Republicans voted against Sandy relief but have their hands out for Texas now. That’s politics being made out of a disaster — it’s just the kind of partisan politics that is fully inside the comfort zone of conventional media, politics that conveniently skirts the reality that placing the interests of fossil fuel companies ahead of the need for decisive pollution control has been a deeply bipartisan affair.
In an ideal world, we’d all be able to put politics on hold until the immediate emergency has passed. Then, when everyone was safe, we’d have a long, thoughtful, informed public debate about the policy implications of the crisis we had all just witnessed. What should it mean for the kind of infrastructure we build? What should it mean for the kind of energy we rely upon? (A question with jarring implications for the dominant industry in the region being hit hardest: oil and gas). And what does the hyper-vulnerability to the storm of the sick, poor, and elderly tell us about the kind of safety nets we need to weave, given the rocky future we have already locked in?

With thousands displaced from their homes, we might even discuss the undeniable links between climate disruption and migration — from the Sahel to Mexico — and use the opportunity to debate the need for an immigration policy that starts from the premise that the U.S. shares a great deal of responsibility for the key forces driving millions from their homes.
But we don’t live in a world that allows for that kind of serious, measured debate. We live in a world in which the governing powers have shown themselves all too willing to exploit the diversion of a large-scale crisis, and the very fact that so many are focused on life-and-death emergencies, to ram through their most regressive policies, policies that push us further along a road that is rightly understood as a form of “climate apartheid.” We saw it after Hurricane Katrina, when Republicans wasted no time pushing for a fully privatized school system, weakening labor and tax law, increasing oil and gas drilling and refining, and flinging the door open to mercenary companies like Blackwater. Mike Pence was a key architect of that highly cynical project — and we should expect nothing less in Harvey’s wake, now that he and Trump are at the wheel.
We are already seeing Trump using the cover of Hurricane Harvey to push through the hugely controversial pardoning of Joe Arpaio, as well as the further militarization of U.S. police forces. These are particularly ominous moves in the context of news that immigration checkpoints are continuing to operate wherever highways are not flooded (a serious disincentive for migrants to evacuate), as well as in the context of municipal officials tough-talking about maximum penalties for any “looters” (it’s well worth remembering that after Katrina, several African-American residents of New Orleans were shot by police amid this kind of rhetoric.)
In short, the right will waste no time exploiting Harvey, and any other disaster like it, to peddle ruinous false solutions, such as militarized police, more oil and gas infrastructure, and privatized services. Which means there is a moral imperative for informed, caring people to name the real root causes behind this crisis — connecting the dots between climate pollution, systemic racism, underfunding of social services, and overfunding of police. We also need to seize the moment to lay out intersectional solutions, ones that dramatically lower emissions while battling all forms of inequality and injustice (something we have tried to lay out at The Leap and which groups, such as the Climate Justice Alliance, have been advancing for a long time.)
And it has to happen right now – precisely when the enormous human and economic costs of inaction are on full public display. If we fail, if we hesitate out of some misguided idea of what is and is not appropriate during a crisis, it leaves the door wide open for ruthless actors to exploit this disaster for predictable and nefarious ends.
It’s also a hard truth that the window for having these debates is vanishingly small. We won’t be having any kind of public policy debate after this emergency subsides; the media will be back to obsessively covering Trump’s tweets and other palace intrigues. So while it may feel unseemly to be talking about root causes while people are still trapped in their homes, this is realistically the only time there is any sustained media interest whatsoever in talking about climate change. It’s worth recalling that Trump’s decision to withdraw from the Paris climate accord — an event that will reverberate globally for decades to come — received roughly two days of decent coverage. Then it was back to Russia round-the-clock.
A little more than a year ago, Fort McMurray, the town at the heart of the Alberta boom in tar sands oil, nearly burned to the ground. For a time, the world was transfixed by the images of vehicles lined up on a single highway, with flames closing in on either side. At the time, we were told that it was insensitive and victim-blaming to talk about how climate change was exacerbating wildfires like this one. Most taboo was making any connection between our warming world and the industry that powers Fort McMurray and employed the majority of the evacuees, which is a particularly high-carbon form of oil. The time wasn’t right; it was a moment for sympathy, aid, and no hard questions.
But of course by the time it was deemed appropriate to raise those issues, the media spotlight had long since moved on. And today, as Alberta pushes for at least three new oil pipelines to accommodate its plans to greatly increase tar sands production, that horrific fire and the lessons it could have carried almost never come up.
There is a lesson in that for Houston. The window for providing meaningful context and drawing important conclusions is short. We can’t afford to blow it.
Talking honestly about what is fueling this era of serial disasters — even while they’re playing out in real time — isn’t disrespectful to the people on the front lines. In fact, it is the only way to truly honor their losses, and our last hope for preventing a future littered with countless more victims.

If Donald Trump Won't Tackle Climate Change, Then Chicago Will

The Guardian*

Across the US, towns and metropolises like mine are united to meet the Paris climate agreement’s targets and protect our residents and businesses

While the Trump administration is dropping the mantle of leadership on climate change, American cities from coast to coast are picking it up. From small towns to metropolises and from the coasts to the heartland, Republican and Democratic mayors are united in common cause to curb emissions, shrink our carbon footprints and fight for a greener future.
Rather than accepting the White House’s wrongheaded withdrawal from the Paris climate agreement, cities are redoubling our efforts to meeting the landmark accords’ benchmarks. We not only have the power to take action, but unlike Washington we have the will to get the job done.
Just days after Donald Trump’s shortsighted decision, I signed an executive order formalizing Chicago’s commitment to adopting the guidelines of the Paris agreement and reducing greenhouse gas emissions by 26-28% by 2025 (compared with 2005 levels).
Chicago has a head start in this effort. We already cut carbon emissions by 7% from 2010-15, while our economy expanded by 12%.
How did we do it?
First, in 2012 we closed Chicago’s last two remaining coal plants.
Second, we retrofitted over 54m sq ft of buildings to make them more energy efficient, earning Chicago first place in the nation for green building adoption and the distinction as the only large American city to be granted the US Environmental Protection Agency energy tar partner of the year award.
Third, to encourage alternatives to driving, Chicago is in the middle of an unprecedented $8.5bn modernization of our mass transit system. We also created the largest bike-sharing program in North America, adding 108 miles of new protected bike lanes and 47 miles of off-street public bike paths, earning Chicago the accolade of the best city in the country for cyclists from Bicycling Magazine.
Fourth, our Drive Clean Chicago initiative has supported $37m in low and emission zero vehicles, the equivalent of taking 1,700 cars off the road a year. We are now in the process of procuring Chicago’s first fleet of electric buses, charging stations and hybrid police vehicles.
These steps are just a downpayment on the work ahead to meet the benchmarks of the Paris climate agreement. Looking over the horizon, by 2025 Chicago will be the largest city in the country where every public building is powered by 100% renewable energy. Outside our buildings, we are converting all of our city streetlights to LED by 2021.
American cities have the power and the will to take action collectively and in our own communities. We control the levers of planning, land use and development – and we can use these tools to turn promises and commitments into results.
This fall, Chicago will host the first North American Climate Summit, a new forum for leaders from across the US, Canada and Mexico to exchange innovative ideas and strengthen coordination and collaboration in our common fight for a sustainable future.
The summit will build on the strength of successful existing partnerships including the C40 Cities Climate Leadership Group as well as Climate Mayors, a bipartisan coalition of more than 300 municipal leaders from across the US. We are also proud to partner with America’s Pledge, a coalition made up of 227 cities and counties, nine states and more than 1,600 businesses committed to upholding the Paris climate agreement.
In Chicago and cities across America, we are sending a clear signal: we will not be deterred and we will not let the truth about climate change be obscured. When the Trump Environmental Protection Agency took down information on climate science from their website, Chicago put it up on our city website. More than a dozen other American cities followed suit.
Something is wrong when a president will do anything to protect every Confederate statue in every city and town, but not one thing to protect those cities and towns from rising sea levels, severe storms and other climate change impacts that threaten municipalities’ very existence.
We hope that Washington finds the courage to lead, but in the meantime we are going to keep pushing forward by cutting emissions, reducing our reliance on coal and adopting the Paris climate agreement locally. Our residents and businesses demand nothing less.
