You don't get to hear from Peter Woolcott all that much in public, even though he is a pivotal character in Australia's international climate change negotiations.
Woolcott is Australia's ambassador for the environment and for the past 14 months has led the country's negotiating teams at UN climate talks.
The reason you don't hear from him (and that perhaps you've never heard of him, full stop) is that as a civil servant working in the highly politicised and supercharged issue of climate change, public statements tend to come from politicians.
Requests for statements are routinely batted back to a ministerial office in Canberra, not necessarily because Woolcott doesn't want to answer but because this is simply how it's done.
Woolcott has, in his words, "spent years in the multilateral trenches" and knows that it can be "a slow-moving and frustrating business".
Just two weeks before he heads to the major international talks in Paris, he delivered a rare and so-far-unreported speech where he set out in exhaustive detail what Australia wants from the meeting.
In an hour-long presentation to the Global Change Institute in Brisbane this week the career diplomat gave a fascinating insight into the changing world of the UN framework convention on climate change (UNFCC) – the umbrella agreement under which all the UN climate deals operate.
He explained how the system of multilateral talks was "struggling to cope" with the expectations and demands of a rapidly changing world.
In Paris, he said Australia wanted a deal that would set the world on a pathway to keeping global warming below two degrees. The deal should not be seen as an end point, but as a "waypoint".
In terms of a collective global problem, "issues do not get any bigger" than climate change, he said.
"Left unchecked, it will magnify existing problems and increase pressure on resources including land, water, energy, food and fish stocks. It has the potential to erode development gains, undermine economic growth and compound human security challenges."
Last week's terrorist attacks would, he said, "only strengthen the resolve" of the French government to come out of the talks with an ambitious deal.
He speculated that the success of the Paris agreement could boil down to the willingness of richer countries to commit to financing for developing countries. In exchange for this, developing nations could then sign the deal.
So here's what Woolcott had to say about Paris; about multilateral international talks; about the UN; and about climate change.
It's long, but think of it as a briefing for the Paris talks by the person representing the Australian government's agenda who has been, and will be, in the room. I'll be "outside the room" for the second week of the talks.

Woolcott on shifting powers
"Twenty years ago the US and Europe could often dictate the terms of the debate. If they wanted to push something through strongly enough, they could do so. Now it's different and the game has changed. There are now no longer one or two hegemonic powers and power is shifting to coalitions."
Woolcott said coalitions such as Brics (China, India, Brazil, South Africa and Russia) "occupy critical positions". Other emerging powers such as Indonesia, Turkey, Egypt, Pakistan and Nigeria were "similarly focused on occupying a place at the top table and preserving their political and economic freedom of movement."
"We are also dealing with a much more fluid ideological landscape. A significant number of these emerging powers want the west's material progress but they do not want to sacrifice their own cultural identities and political traditions.
The west's vision of modernity and human rights is under challenge. Nationalism, state sovereignty, state capitalism and religious identity are growing forces and are being used to strike at fundamental concepts such as freedom of expression and responsibility to protect.
Secondly, behind this shift in the power dynamics is the increasing pace of globalisation and the extraordinary wealth transfer from west to east.
Third, not only is there a shift in national power, but there is a shift in the very nature of power. As a result of new communications technologies exemplified by social media, power is moving to coalitions and networks that are able to effectively influence state actions, particularly in liberal democratic societies.
What characterises them is their ability for mass organisation, speed and multiple and diverse actions, and you see this very much in the environmental space. The strength of these networks whether they be civil society, sub-national entities or business groupings, will only grow and increasingly questions will arise as to how they should exercise this power and to who they are accountable.
These factors greatly complicate the decision-making and are putting significant stress on international governance, at a time when we need the system to work effectively."
Woolcott on responding to climate change
"The policy response will require coordinated action in an unprecedented way across economic and ideological divides. The stakes are high and the multilateral institutional tools that are at our disposal are somewhat compromised.
Part of the problem is history. In the multilateral setting, we tend to rely on the outcomes of old battles where they be previously agreed language, or previously agreed processes or the ways of conducting themselves and they tend to dictate or try and dictate the future.
This is Ok if we are content with incremental progress, but we are not and we need to change the very basis in which we address climate change."
He said that the UNFCCC had "set up a divide between the developed world and the developing world" and that it was still struggling to shake this off.

Woolcott on what Australia wants in Paris
"What Australia wants in Paris is a strong and effective legal agreement that is applicable to all countries and drives serious reductions in emissions while ensuring economic prosperity.
It has to be an agreement that reflects the real world and the way it has changed and continues to change.
We are however stuck with an outmoded convention that divides the world into the developed and developing country camps – annex 1 and non-annex 1 countries.
It assigns them very different obligations and responsibilities, all based on GDP levels from 1992. China, Singapore and Korea, for example, are all deemed developing countries for the purpose of climate action.
We have little chance of tackling climate change based on these divisions. Let me reinforce this point with a few statistics.
In 1992 only three non-annex 1 countries – or to put it simply developing countries – were among the 12 largest emitters. Today this has risen to seven.
Now non-annex 1 countries represent two-thirds of total emissions and this will be nearly three quarters of total emissions by 2030.
So not only is the engineering obsolete, the decision-making machinery is cumbersome. The 195 parties to the convention must make decisions by consensus.
While it is right that responses to global problems endorsed by most countries have a legitimacy that agreements negotiated amongst smaller groups lack, the reality in UNFCCC is that nothing is agreed until everything is agreed and decisions usually result in lowest common denominator outcomes.
So the UNFCCC reflects the microcosm of problems of the wider UN. We are between multilateral worlds. The old world dominated by the west can no longer dictate – nor finance alone – the solution.
The new world has not yet arrived and the emerging powers are reluctant to take on responsibilities which might compromise their freedom of manoeuvre and their economic developments."

Woolcott on success in Paris
"Success at Paris is not a given. As I said, change is hard.
There is a strong sense that the world's largest two emitters are working collaboratively to an agreement in Paris although they have slightly different visions as to what that agreement will look like.
These are all critical differences to what unfolded in Copenhagen. There are others, in particular what is the utilisation of a clever strategy of having states announce their intended nationally determined contributions – that is their post-2020 emissions targets – before Paris. To date 161 countries have announced post-2020 targets, which include all of the G20 countries and covers over 90% of global emissions. This is quite a remarkable statistic.
While they vary in ambition and detail, it is an extraordinary number and will go higher before we reach Paris.
The deal in Paris will be built around these nationally determined targets. I should be clear here. Paris is about negotiating the agreement text. It is not about negotiating the targets.
But in setting targets in this bottom-up way we have recognised the limits of multilateralism in addressing climate change.
We have recognised that the top-down multilateralism – the old way of doing it which imposes emissions targets on countries – doesn't work and that if we are to ensure a global, effective and durable solution then we need to set up a system whereby it might be self-determined, is subject to public and peer pressure, it is subject to review and transparency and cognisant of the science.
We have also learned that a successful climate deal needs participation before ambition. It needs all countries on the same footing for taking action before we ramp up that action. It would be pointless to have a deal on paper if the US or China won't sign up to it.
So the agreement in Paris will be framed by what countries can accept given their national circumstances. For example we expect that only the obligation to have a target, not the target itself, will be legally binding – an approach that gets around the US difficulties of treaty verification.
So how will Paris work out? It is hard to predict, but my sense is that the real danger is not that there will be no agreement but that it will be a minimalist agreement – that Paris will tie a neat bow around the INDCS and that much of what we want in terms of transparency, accountability, durability and review may be lost.
The minister at a negotiating level will be working hard to avoid this and for an ambitious and durable agreement.
Within the UNFCC Australia has developed significant multilateral muscle. We are effective operators and play the honest broker well, especially from our role as chair of the umbrella group – the negotiating group that includes the US, Japan, Russia, Canada, New Zealand and Norway.
The outcome on how emissions targets are captured in the Paris agreement will be due in no small part to the Australia's 2009 idea … of creating a schedule for commitments. We including the French are also engaged in seeking to manage expectations in a realistic way.
Let me repeat, Paris will not put us on track to keep global warming below two degrees. That should not lead to a Copenhagen moment with headlines the morning after saying we have failed. Paris is a waypoint, not the final destination in our efforts to tackle climate change.
What is different about Paris compared to our past efforts is that we are building a wider, silver buckshot approach which better harnesses national, bilateral and non-government efforts and builds into the agreement a dynamic and durable process that puts us all on the same floor and allows us to work within the two-degree goal.
The Paris agreement must reflect and build on the real world action that has already moved well passed old political divisions so rampant in the United Nations and establish partnerships for the future. It is a huge test for the system."
Woolcott on beating 2C
"The international community is guided by the science and is seeking to limit the rise in global temperatures to below two degrees Celsius.
Now there is no expectation that Paris will show that we are on track to meet that two-degree goal … But what we want the agreement to do is to set out an agreement to build global action over time which has all countries similarly engaged and provides us with a pathway to stand the two-degree goal."
Woolcott on what should be in the Paris deal
"Australia has been working for three things in the agreement.
First, to seek that all countries, especially major economies, commit to mitigation efforts that are nationally determined but also meet minimum-quality criteria for mitigation.
Secondly, to ensure accountability and transparency in how states are meeting their commitments. We need this in order to judge how we are tracking collectively against the below-two degree goal, and to see whether our neighbours, trade partners and competitors are doing what they say.
This transparency will build confidence which in turn will build greater ambition.
And thirdly a durable process that will allow us to build action over time to keep within a two-degree guardrail through a regular periodic process that prompts states to revisit and update their national mitigation efforts through five-year cycles.
Developing countries have argued that this agreement must give legal status to adaptation. We understand these concerns and have sought to be constructive in addressing this. The Paris outcome should encourage the mainstreaming of adaptation and promote the sharing of best practice. We need to assist the most vulnerable to manage and adapt to the economic and security implications of climate change and we need to build disaster-response capacities and strengthen economic and governance resilience within countries."
Woolcott on Pacific islands and Australia
"For the small island states, particularly in the Pacific, climate change is an existential challenge.
Our development program in the Pacific is focused on climate resilience and building in disaster-response capacities. Despite the occasional heightened rhetoric from the South Pacific, at the practical level we work closely with them in pursuit of an ambitious Paris agreement.
We also know that Australia needs to prioritise resistance to climate impacts nationally and through international partnerships.
We will produce a national climate resilience and adaptation strategy which Minister Hunt will release at Paris."
Woolcott on Paris sticking points
"There are many contentious issues still to be resolved – things like loss and damage, legal form, transparency and accounting, cycles of compliance, review and long-term goals – but the two biggest issues are finance and differentiation.
These are inextricably linked. Ultimately it may well come down to the ask by the developing world in relation to climate finance in order to secure their participation in a common and legally binding agreement to tackle climate change."
Woolcott said there had already been good progress towards a commitment made in Copenhagen to make US$100bn a year available to poorer countries by 2020.
"The amounts required in the future are enormous both for adaptation and for a low emissions future. A recent Bloomberg energy report has stated that up until 2040 US$12.2tn will be required for power generation and some 78% of this to the developing world. We are dealing with vast sums of money.
Much of this finance will have to come from the private sector. And will also require an expanding country donor base."
Woolcott on the role of civil society groups and business
"Civil society has always played a highly constructive role and will continue to do so. They might be styled as observers but they are in fact often participants and not only pressure governments but are often part of developing countries' negotiating teams.
What is changing dramatically now is the role of business and industry. The private sector and innovation are going to be critical if we are going to tackle climate change. They have viewed the UNFCCC as irrelevant at best ….
One of the things that has changed is that the national determination of targets has created the necessary domestic conversations with stakeholders.
Australia has seen commitments from a host of major companies – the ANZ, the National Bank, BHP Billiton and AGL – in Paris there will be a series of themed action days and non-government meetings involving business, industry, NGOs, cities and other sub-state actors.
The aim is to create a link between the on-ground action by these organisations with the political leadership that multilateral processes provide, as well as governance. The French have been exceptional in driving this change in approach which recognises the private sectors crucial roles in tackling climate change."
He said Bill Gates' announcement to provide $2bn of his money for research and development to tackle climate change "shows how the ground is changing".
"This more expansive approach to engendering climate action beyond just states gets around a core criticism of multilateralism – that once institutional solution is imposed, it cauterises the need to think about the problem any more.
The Paris action days will seek to turn this criticism on its head by using an institutional process to think more deeply and widely about how to act on climate change.
While it is also changing the relationship between civil society and the corporate sector – and this is a very interesting development – there is an increasing understanding that civil society and corporate Australia do not need to be on opposing sides of the divide and they need to work constructively together.
In this context I refer to the statement of principles by the Australian Climate Roundtable which really is an impressive illustration of this collaboration.
These groups have real and growing power in the multilateral system and with power comes both responsibility and accountability.

We Can't Beat the Tide of Climate Change if We Don’t Stop Relying on Coal

It is always a pleasure to be in Australia, a neighbour and a strong supporter of our young nation of Kiribati throughout its nation-building journey. The relationship between Kiribati and Australia has endured over generations and has grown from strength to strength. The relationship is predicated on shared mutual interests and being part of one region and one ocean. Even more important are the personal links that our people have nurtured and respected throughout the years and which I am confident will last.
Indeed our mutual respect for each other remains the basis for our shared interest in ensuring the preservation of this planet our one and only home. It is my very strong belief that our two nations will endeavour to do all we can to reduce greenhouse gas emissions.  It is in this context that on behalf of my people, we are seeking commitments from the world's governments for a moratorium on new coal mines.
Anote Tong, President of Kiribati
The scientific evidence is clear; we need to produce and burn less coal. Furthermore, the age of coal and steam is coming to an end with the world acknowledging that there should be a transition towards cleaner and renewable energy. The moratorium on new coal mines is but the first step towards a world that is less dependent on fossil fuel. Indeed, there is simply no plausible scenario in which a world that is tackling climate change needs enormous new coal mines.
Since calling for a halt to the construction of new coal mines in August, the voices of the Kiribati people have already been joined by those of 11 other Pacific islands. Globally our call has been supported by voices as diverse as Sir Nicholas Stern and Naomi Klein. Recently in Australia, 61 eminent scientists, economists, sports people and church leaders supported our call. I take this opportunity to convey my appreciation to all of them for their support and sincerely hope that many more will be able to join this call.
We have not asked the world to cease coal production immediately. We are simply asking that the world stop building new mines. Science has confirmed that the production and use of coal is and will contribute to increasing global emissions. For my people who are at the front line of climate change, any concrete action towards the reduction of global emissions is ensuring their survival as a nation, as a culture and as a people.
It is against this background that it is disheartening to note the decision of the government of Australia to approve the Carmichael mine in Queensland. In doing so, it is basically forfeiting those of us who have the greatest to lose from the impacts of climate change, in support of relatively small and wealthy interest groups such as the coal industry.
As the Paris climate talks get closer, leaders from around the world are preparing to take part in a process which is designed to allow each of them to achieve more by working together than they could possibly achieve on their own. We can no longer act as individual nations in isolation of the rest of the world.
I am very optimistic that we as leaders will be able to act together to preserve this planet by taking positive steps towards cleaner and renewable energy. I am very confident that the world as a whole will understand that renewable energy is the only option and one that makes economic and financial sense.
Indeed, Australia is one of the leading nations in terms of technological innovation for renewable energy. Furthermore, the growing support for a moratorium on coal by the Australian public and around the world is acknowledgement that to ensure the preservation of this planet our one and only home, renewable and clean energy is the only way forward.
For the sake of our children and our grandchildren, let us do what is right for them.

A Breathing Planet, Off Balance

NASA



Earth's oceans and land cover are doing us a favor. As people burn fossil fuels and clear forests, only
half of the carbon dioxide released stays in the atmosphere, warming and altering Earth's climate. The other half is removed from the air by the planet's vegetation ecosystems and oceans.
As carbon dioxide levels in the atmosphere continue their rapid, man-made rise past levels not seen for hundreds of thousands of years, NASA scientists and others are confronted with an important question for the future of our planet: How long can this balancing act continue? And if forests, other vegetation and the ocean cannot continue to absorb as much or more of our carbon emissions, what does that mean for the pace of climate change in the coming century?
These questions are a major priority for NASA's Earth science research program, and the agency is preparing to ramp up its field studies, satellite monitoring and computer modeling to help answer them. Carbon is a fundamental element of life on Earth, but the increasing amount of carbon in the atmosphere — in the form of carbon dioxide and methane molecules — is also the primary element driving our warming climate. Scientists are studying how carbon moves through Earth's atmosphere, land and ocean with an array of tools, including a new dataset of the ebbs and flows of carbon in the air.
"Today and for the past 50 to 100 years, the oceans and land biosphere have consistently taken up about half of human emissions," said Dave Schimel of NASA's Jet Propulsion Laboratory, Pasadena, California. "If that were to change, the effect of fossil emissions on climate would also change. We don't understand that number, and we don't know how it will change in the future."

Earth's land and ocean currently absorb about half of all carbon dioxide emissions from the burning of fossil fuels, but it's uncertain whether the planet can keep this up in the future. NASA's Earth science program works to improve our understanding of how carbon absorption and emission processes work in nature and how they could change in a warming world with increasing levels of emissions from human activities.

So researchers at NASA are tackling the questions from a number of angles. They're monitoring land, atmosphere and oceans with airborne and satellite sensors and digging into the first results from a new satellite observatory measuring carbon dioxide. And they're pulling all the information we have into supercomputer simulations to understand how our Earth responds to changes in carbon emissions.
"There are all these amazing data sets, but none of them quite give us the entire carbon story," said Lesley Ott, an atmospheric scientist with the Global Modeling and Assimilation Office at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "The models help us tie all the observations together to get at how atmospheric carbon is varying and changing, but we still have a lot of work left to do to understand how carbon moves among the land, oceans and atmosphere."

Carbon on the move
Carbon naturally cycles through Earth's environments. Trees and other plants take up carbon dioxide and turn it into the building blocks of roots, stems and leaves. Some of that carbon stays in the soil as the vegetation dies and gets buried. Some is released back into the atmosphere as carbon dioxide through plant respiration, and both carbon dioxide and methane — another potent, carbon-based greenhouse gas — can be released through decomposition, land clearing and wildfire. The ocean absorbs carbon dioxide from the atmosphere, and the tiny water-dwelling plants called phytoplankton take up the gas as well. Over many millennia, the pace of carbon cycling is governed by volcanic emissions and weathering of rocks.
For most of human history, carbon has been in a more-or-less steady cycle. This cycle has been thrown off balance as people burn fossil fuels — carbon that has been long buried underground as oil, gas and coal — and as forests are cleared and soils are turned for agriculture. All of these contribute to increasing carbon emissions. While the amount of carbon dioxide emissions that ecosystems absorb from the atmosphere each year varies quite a bit, the fraction in the long run has averaged out to about half.
More carbon dioxide and methane in the air means warmer global temperatures. Warmer temperatures can disrupt some ecosystems and impact their ability to absorb more and more carbon. An even more imbalanced carbon cycle will cause greater variability and consequences that are not yet fully understood.
NASA's newest tool in tackling the complex question of carbon ebbs and flows is the Orbiting Carbon Observatory-2, or OCO-2. Launched in July 2014, the mission measures how much carbon dioxide is in the atmosphere near the planet's surface. With that dataset, researchers can better begin to characterize where carbon is being emitted and absorbed and over what timescales. Mission scientists recently analyzed OCO-2's first year of data, and saw the expected decreases in atmospheric carbon dioxide in the Northern Hemisphere's summer, as plants undergo photosynthesis. They saw upticks in the greenhouse gas over power plants and megacities, and over areas where people clear forests for agricultural use.
"The new, exciting thing from my perspective is we have more than 100,000 measurements each day of carbon dioxide in the atmosphere," said Annmarie Eldering, OCO-2 deputy project scientist at JPL. "Not only do we have a lot of measurements, but they tell us a lot. We can see a change [in atmospheric carbon] of one-quarter of 1 percent from space. Armed now with this pile of data, we can start to investigate more fully this question of sources and sinks and how different parts of the world contribute to these processes."

Plants and ocean lend a hand
Terrestrial plants — from towering Douglas firs to moss growing on rocks — take up carbon dioxide from the atmosphere during photosynthesis, processing it into carbon-containing leaves, stems, branches and more.
"The land helps to mitigate something like a quarter of the carbon dioxide emissions," said Jeffrey Masek, chief of the biospheric sciences laboratory at NASA Goddard. "The question is: What will happen in the future? Can we count on this to continue? Or are land processes going to saturate, in which case we'd see our atmospheric carbon dioxide concentration start to increase much more rapidly."
Monitoring photosynthesis is one way for scientists to study vegetation health and growth in an atmosphere with increasing carbon dioxide. Even though photosynthesis is a process occurring at the microscopic scale on the land and in the ocean, scientists have found the best way to monitor it globally is by satellite.
"If it weren't for satellites, we would have very little understanding of the biological activity of the entire Earth," said Josh Fisher, a climate scientist at JPL. "We know from our field studies about how different ecosystems [vary], but we don't know how robust or representative our studies are at the global scale."
The Landsat missions and the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on the Terra and Aqua spacecraft allow researchers to study the greenness of vegetation as a proxy for photosynthesis, and therefore carbon dioxide uptake, across the globe. Scientists are also using OCO-2 to take a big-picture look at these small-scale processes, capturing the faint fluorescence given off by terrestrial plants during photosynthesis, Eldering said. With fluorescence, scientists have a new way to observe how active – or not – these green ecosystems are.

Forests are one of the major carbon sinks, which are areas that absorb large amounts of carbon dioxide from the atmosphere, storing it for decades in trunks and roots. Satellite observations have illustrated how green plants have expanded their territory in North America, as warmer temperatures allow them to grow farther north. Height-measuring instruments, like radars and lidars, add a third dimension to the land cover information, allowing researchers to estimate how much material — and therefore how much carbon — is stored in a forest. NASA has plans to launch satellites as well as put a sensor on the International Space Station (ISS) to measure this third dimension of forest structure and improve estimates of how much carbon is stored in large forests.
NASA has targeted a variety of future field campaigns, satellites and ISS sensors to improve our understanding of how much carbon is being stored in terrestrial ecosystems and how this could change as patterns of drought, fire and forest structure itself shift in a changing climate.
More carbon in the atmosphere can act as a fertilizer and give vegetation a boost, increasing the storage of the greenhouse gas at least temporarily. But any increased plant growth due to more carbon dioxide in the air can't continue forever, researchers say. Eventually, the vegetation will run out of water or other nutrients necessary for enhanced growth, while changes in temperature and rainfall could also alter growing conditions. Without these essentials, vegetation can't keep taking up increasing amounts of greenhouse gases from human-caused emissions.
NASA scientists are working to understand if our land and ocean can continue to absorb carbon dioxide at the current rate – and for how long. Available to download, this infographic covers the science behind Earth's carbon cycle, what's changing and how NASA is studying the rise of carbon dioxide.

In some regions, forests are releasing more carbon than they're storing. Satellite images have also documented the transition of green, healthy forests through land clearing and events like wildfires and insect infestations, which are increasing in drought-stressed environments. Droughts themselves slow down the growth of vegetation, slowing down the uptake of carbon in regions such as the Amazon. This can flip the balance for forests and other ecosystems – from an overall absorber of carbon to an overall emitter of the greenhouse gas. While natural climate variability may cause such year-to-year changes, scientists are concerned that climate change could turn forests into sources of carbon on a regular or even annual basis.
Ocean scientists are facing similar questions about carbon. The ocean water itself absorbs carbon dioxide from fossil fuel emissions. Doing so, however, changes the chemistry of seawater. As surface water in the ocean continues to warm, uptake of carbon dioxide will slow down.
Oceans also contain carbon in the form of plants and animals, including phytoplankton — microscopic plants that take up carbon dioxide through photosynthesis, just like their larger, land-based cousins. Phytoplankton form the base of the ocean food web, and those that survive being eaten by zooplankton will die, sinking to the bottom of the ocean — taking their carbon stores with them to be decomposed. Changes to ocean chemistry and circulation due to climate change may alter this biological carbon pump, potentially triggering a release of the carbon stored deep in ocean sediments.
In the North Atlantic the distribution of phytoplankton species is changing due to warming waters, notes Carlos Del Castillo, ocean ecology laboratory chief at Goddard. A different mix of phytoplankton species will take up different amounts of carbon dioxide — which could result in even further changes to the ocean's carbon cycle. "It's a cycle, which we hope is not a vicious one," Del Castillo said.

Getting a global view
To get a more complete picture of this global carbon cycle, NASA scientists are combining many different approaches to studying the land, ocean and atmosphere. They use NASA's wealth of data on carbon dioxide in the atmosphere with weather and climate models to monitor every response of Earth processes to the increasing burden of carbon dioxide.

"You've got all these little individual sources of change — the insects, the fire, agriculture expanding and other land use — all this stuff flickering around on the ground, varying from year to year, over decades. And then you've got these integrated observations of the atmosphere," Masek said. "You need models that incorporate these processes — all of them. And then if that model is reasonable, we should be able to predict what the atmospheric carbon dioxide looks like. It's a tough job."
With the supercomputers at NASA, scientists take in all the information they can — from all the Earth science fields they can. They program computer models to take all these inputs and try to determine whether the land and oceans will keep giving people an assist.
"Ultimately the goal of all of this work is to be able to predict what's going to happen with the carbon cycle," Ott said. "How much carbon is going to be taken up by the land and ocean? We need to know how that's going to change in the future."
By coming at the problem from multiple vantage points, using a range of measurements and tools, scientists are strengthening the models to give us a better picture of what our carbon-directed climate will look like in the coming years and beyond.

The Guardian View on Paris, Terror and Climate Change: Shaping the Future

The Guardian

It is hard for France’s capital to look beyond the terror attack, but the decisions taken at the UN climate change conference may in the end matter more

While Europe is on high alert against another murderous terrorist attack, it will be hard for Paris to look beyond the next 24 hours. But soon delegates start arriving in the French capital for preliminary meetings ahead of COP21, the United Nations climate change summit which will be launched on 30 November with all the grandeur attendant on a gathering of global leaders.
There is a certain symmetry to the two events that goes beyond the nightmare task facing France's overstretched security forces. As the UK foreign secretary Philip Hammond pointed out in an important speech in the US only days before the Paris attacks last Friday: "Unchecked climate change … could have catastrophic consequences – a rise in global temperatures … leading in turn to rising sea levels and huge movements of people fuelling conflict and instability."
There are reasons to be optimistic about a useful outcome from these negotiations, not least the determination of President Barack Obama's team to deliver a deal with some kind of legal force. But any deal will mark the start rather than the end of the process.
The world has learned from previous failures. The innovation of asking every country for its own intended nationally determined contributions in advance of COP21 is that they reduce the wriggle room, at least for the time being.
Wednesday's big speech from the UK energy secretary Amber Rudd, setting a cut-off date of 2025 for coal-fired power stations, will underline that sense of commitment and should help to build some momentum ahead of the talks, even though it is only a small advance on the policies she inherited.
It is also a necessary reaffirmation of the Conservatives' pledge to green the electricity supply which had begun to seem questionable after its widely criticised decision to end subsidies to wind and solar power unexpectedly early.
Ms Rudd said she was resetting UK energy policy and if she didn't quite do that, she did make a more or less coherent pattern from the fragments that have emerged since the election in May. It is a plan. Yet with its contradictions and conditional undertakings, it did not quite add up to a clear path through the so-called energy trilemma: the balance to be struck between security, sustainability and affordability.
Take the commitment to phase out coal over the next 10 years: it came with the caveat that it would not happen unless there was a clear and reliable alternative. Given the continuing uncertainty over new nuclear (which, in the Rudd plan, is what stands between decarbonisation of electricity supply and the lights going off), that means new gas-fired power stations – less dirty than coal, but still a finite fossil fuel.
The plan will also entail exploiting shale gas, which is so far entirely untested in the UK and already politically neuralgic. And if gas is to be the core of energy supply beyond 2030, when electricity is supposed to become carbon free, then serious money needs to go into developing carbon capture and storage. CCS merited just one mention in Ms Rudd's speech.
As for the decision to phase out subsidies for renewables, it was defended as part of a necessary move towards making green energy competitive with other fuels, even though that is something nuclear power will not be for the foreseeable future. However, there was a little good news for renewables: there will be subsidy for new offshore wind, when it can compete with the cost of new nuclear. The bad news is that although off-shore generation costs have fallen by a fifth in two years, there is still a distance to travel.
Decarbonising power supply is proving hard enough. But it poses a lesser challenge than weaning the nation off its gas-fired heating, and luring it out of its diesel- and petrol-powered cars. That puts the greatest burden of reducing carbon emissions on electricity generation.
The cheapest way to get there, the way that would make most difference to consumers and shrink their energy bills by the greatest amount, is to increase energy efficiency. Ms Rudd seems to have left that part of her plan in her pending tray.
Britain does have a positive message to deliver in Paris, and that can only be good news. But the world has not yet come up with a way of holding global warming below the critical 2C. The serious negotiation in Paris will be about monitoring and enforcing compliance and setting a formula to ratchet up commitments into the future.
For the UK, the Rudd plan, heavy on gas and light on efficiency, will make the next step in carbon emission cuts harder than it needs to be.
