EU wants Paris climate deal to cut carbon emissions 60% by 2050 
The world's states should commit to a legally binding emissions cut of 60% by 2050, with five-yearly reviews, at the Paris climate summit in December, according to a leaked EU document. The EU's "Road to Paris 2015" communication, which is due to be formally published tomorrow, says "major economies, in particular the EU, China and the US, should show political leadership by joining the Protocol as early as possible". Environmentalists were disappointed by the document's lack of ambition, according to the Guardian. RTCC summarises the key points from the document and notes: "The EU lays out its Intended Nationally Determined Contribution (INDC) for its 28 member states in a table, setting a model for other countries to follow when they release their own [INDCs] later this year." The Guardian 

Sen. Markey to investigate industry funding of climate studies 
Senator Ed Markey, a Democrat, wants oil and coal companies to reveal the extent to which they have funded research questioning the causes of climate change. Following the weekend revelations about the climate sceptic scientist Wille Soon not fully declaring his funding from fossil fuel interests, Markey said he will soon write to various fossil fuel companies in an attempt to find whether they are paying for climate sceptic research. Meanwhile, the Smithsonian Institute, where Soon works, has asked its inspector general to review the Soon allegations. The Hill 

Global call for EU biofuels reform ahead of key vote 
Almost 200 organisations from across Asia, Africa and Latin America have written to EU parliamentarians expressing their concern at the "devastating impact" Europe's demand for biofuels is having on forests in their regions and its "significant" contribution to rising greenhouse gas emissions. Under the 2009 Renewable Energy Directive, 10 per cent of energy used in the EU's transport sector must come from renewable energy sources, a target that is likely to be met almost entirely through biofuels, the majority of which are grown in developing countries. MEPs vote today on whether to introduce a cap on the use of crop-based biofuels at seven per cent within the 10 per cent target. BusinessGreen 

Shellfish face high risk from ocean acidification, new study finds 
As oceans become more acidic, the US shellfish business is facing "high economic risk" in 15 out of 23 coastal states, according to a study published in Nature Climate Change. Massachusetts tops the list of states facing the highest risk, the study concludes. Shelled mollusks such as oysters, clams and scallops are extremely sensitive to ocean acidification, according to the paper. The US shellfish industry brings in $1bn annually, according to the report. Guardian Sustainable Business Blog 

Burst of warming may end lull in rising temperatures 
Met Office scientists have found that there is a 60 per cent chance the global surface temperature "hiatus" will be followed by a five-year period of rapid warming at twice the usual background rate of around 0.2°C per decade. The models also suggest there is a 15 per cent chance the hiatus will continue for five more years. Carbon Brief also reports the study's findings. New Scientist

Surface warming 'hiatus' could stick around another five years, say scientists

  • 23 Feb 2015, 16:30
  • Roz Pidcock

Don't be surprised if the slower pace of warming we're seeing at the Earth's surface lasts for another five years, scientists say.

new paper out today puts the chances of the so-called "hiatus" staying until the end of the decade at about 15 per cent, or one in six.

But the heat hasn't gone away. The scientists say most of it is lurking in the deep ocean and we can expect the pace of warming to pick up when this heat gets released again.

Slower surface warming

Since 2000, the temperature at the Earth's surface  hasn't warmed as quickly as it has in previous decades, despite greenhouse gas emissions rising  faster than they were before.

A growing body of evidence is  homing in on the  Pacific Ocean as the main culprit for why we're seeing "unexpectedly modest" warming, as the Nature Climate Change paper puts it.

Scientists think a natural fluctuation is causing heat to find its way to the deep ocean in the Pacific, where it doesn't warm the atmosphere as much it would if it stayed at the surface.

A number of recent studies have found that periods of faster and slower warming  aren't unusual in Earth's temperature record. It's what scientists expect as these natural cycles flip-flop between their  different phases, superimposed on top of greenhouse gas warming.

But what are the chances of natural variability being strong enough to offset some, or even all of the warming expected from greenhouse gases?

The new paper by Dr Chris Roberts, an ocean and climate specialist at the Met Office Hadley Centre, and colleagues at the University of Exeter sheds some new light on this question.

Odds of a 'hiatus'

The new paper uses a suite of climate models to examine past temperatures with and without greenhouse gas forcing. The authors find there's a 28 per cent chance natural variability could cause a five-year long 'hiatus'.

The scientists define 'hiatus' as a period during which the observed temperature rise is less than the warming expected from greenhouse gases of 0.2 degrees Celsius per decade.

Uncertainty behind climate projections could be cut in half by 2030, study shows

Scientists will soon be able to forecast climate change more accurately, according to new research. Projections of future temperature rely on estimates of how sensitive the Earth's climate is to rising emissions, and the uncertainty in those estimates could be halved within 15 years.

More certainty about the climate's sensitivity to emissions means a better assessment of our chances of keeping global temperature rise below the two-degree limit, the researchers say.

Climate sensitivity

Climate sensitivity is the amount of warming we can expect when carbon dioxide in the atmosphere reaches double the level before the industrial revolution. On current emission trends, we're set to reach that point shortly after 2050.

There are two ways to express climate sensitivity. Equilibrium Climate Sensitivity (ECS) refers to the total amount of warming once the Earth has had time to adjust fully to the extra carbon dioxide. ECS allows for 'feedbacks' in the climate system that can amplify or slow the pace of warming, many of which act over decades or even centuries.

An alternative option is the Transient Climate Response (TCR), which is the warming at earth's surface we can expect at the point of doubling. This doesn't take into account long term feedbacks, and so estimates of TCR are lower than for ECS.

In its 2013 report, the IPCC estimates TCR is likely to lie between 1.0 and 2.5 degrees Celsius. The new research, published in Nature Geoscience, suggests scientists will be able to reduce the uncertainty around these estimates by about 50 per cent by 2030.

Bigger proportion

The new paper deals with one way to estimate TCR, which is to compare how much greenhouse gases have risen over the industrial period with observations of how much the temperature has changed in that time.

But factors such as aerosols and other greenhouse gases have contributed to the observed temperature change, making it difficult to calculate TCR from historical observations.

Aerosols are released into the atmosphere when fossil fuels are burned. These tiny particles have a direct effect on temperature by scattering sunlight, and an indirect effect by stimulating cloud formation, preventing sunlight reaching Earth's surface.

Although scientists know that aerosols have an overall cooling effect on the climate, they aren't as certain about the size of the temperature effect as they are for carbon dioxide.

But uncertainty over aerosols is set to be less of a problem in the near future, the study says.

While emissions of carbon dioxide are expected to rise in the next few decades, emissions of aerosols and other greenhouse gases are expected to slow, or fall. This means carbon dioxide will make up a bigger proportion of the human-caused factors affecting the climate.

You can see this in the graph below: the influence of carbon dioxide on the climate (red line) is projected to increase more rapidly than aerosols and other gases over the next 15 years (blue and green lines).

Labour leader Ed Miliband's plan for the Paris climate deal

  • 23 Feb 2015, 15:20
  • Simon Evans

Prospective UK prime minister Ed Miliband has set out his vision for a global climate deal, in an article for the Observer newspaper.

The Labour leader's article says tackling climate change would be one of his highest priorities as prime minister, calling it an "economic necessity" and the "single most important thing we can do for our children and our grandchildren". He says last year's winter floods showed climate change is a security threat to the UK, as well as globally.

Carbon Brief summarises reactions to the piece and looks more closely at Miliband's vision for the Paris climate deal, due to be agreed at the end of this year.

Political reactions

The piece has attracted wide press coverage in the UK because of Miliband's decision to appoint former deputy prime minister John Prescott as a senior climate adviser.

Lord Prescott has a long track record in the international climate arena, as does Miliband, who was energy and climate change secretary when the UK Climate Change Act was passed in 2008. Prescott was the lead EU climate negotiator when the Kyoto Protocol was agreed in 1997.

Miliband says of Prescott: "There is no one better than John at bashing heads together to get a deal." In a column in the Sunday Mirror, Prescott says any head-bashing will be of the intellectual variety and says his brief is to "raise ambition on this crucial issue".

The Guardian says the appointment will give Prescott a "frontline general election role", with the BBC taking the same line. The Daily Mail says the move "will be seen as an attempt to turn the clock back to when Labour used to win elections".

In an article for the Express, Leo McKinstry calls Prescott a "charmless old bruiser" and says Prescott's "two Jags" nickname means he has "zero credibility in peddling the green agenda". The Telegraph calls Prescott "the bulldog who saved Labour", but says the appointment may irk Labour's shadow energy and climate change secretary Caroline Flint.

Green energy project stuck on amber 
Conversion of the Lynemouth coal-fired power plant in Northumberland to burn biomass has been delayed after the European Commission said householders facing subsidies to pay for the scheme risk being overcharged. The power plant was one of eight renewable projects to get a new type of subsidy last April, paid for via levies on consumer energy bills. The Department of Energy and Climate Change has said the government would work to resolve the Commission's concerns. BusinessGreen has more on the story.     The Times

British Gas owner Centrica sees profits fall steeply 
Shares in British Gas owner Centrica plunged more than nine per cent yesterday as the company cut its dividend for the first time since it was created in 1997. The response was an "urgent" step to protect its credit rating as warmer weather and falling oil and gas prices led to a 35 per cent drop in annual profits, says the Financial Times. Two of Centrica's 20-year old gas-fired power stations, Killingholme and Brigg, are to close as they are losing money. While most of the blow to profits was down to low oil and gas prices, perhaps a fifth was self-inflicted, caused by errors or poor decisions, says Allister Heath in The Telegraph.     BBC News 

UN climate chief Rajendra Pachauri investigated about sexual harassment 
Police in Delhi are investigating claims of sexual harassment against Rajendra Pachauri, made by a staff member at The Energy and Resources Institute.

Five charts showing how BP's vision differs from a climate-friendly future

  • 19 Feb 2015, 15:00
  • Simon Evans

Oil firm BP says the world is still failing to do enough to tackle climate change, despite major policy announcements over the past year from the US, EU and China.

The latest annual Energy Outlook shows how BP sees the world changing in terms of economic growth, energy use and emissions. While BP expects countries to meet current climate pledges, it does not think they will be enough to avoid dangerous climate change.

Carbon Brief takes a look at how the media reported the Energy Outlook and how BP's vision differs from a climate-friendly future.

Rising energy use and emissions

The BP outlook predicts energy demand will grow by 37 per cent between 2013 and 2035, reports the Guardian. This is "at odds with the fight against climate change", the paper says.

A more climate-friendly future is set out in the International Energy Agency (IEA) two degrees scenario. This shows how energy efficiency must play a large part in limiting emissions.

Global energy demand increases by just 14 per cent between 2012 and 2035 in the IEA two degrees scenario, slower than over the past two decades (blue line, below). In contrast, BP expects the recent rapid growth in energy demand to continue (green line).

BP's outlook expects two thirds of the increase in energy demand to be met by fossil fuels, reports RTCC. Gas would overtake coal as the number one energy source, reports City AM.

The Financial Times reports BP saying that oil producers' cartel Opec will make a comeback while the Times and Independent focus on low expectations for the UK shale gas industry.

The Carbon Brief Interview: Lord Deben, part 1

  • 18 Feb 2015, 11:00
  • Leo Hickman

Lord Deben, or the Rt Hon John Selwyn Gummer, is the current chair of the Committee on Climate Change (CCC). He is also chair of the sustainability consultancy Sancroft International, honorary president of the Global Legislators Organisation (GLOBE International) and a non-executive director of the Catholic Herald newspaper. Gummer was a Conservative MP from 1970-1974 and from 1979-2010. From 1993-1997, he served as the Secretary of State for the Environment.

In Part 1, Lord Deben discusses the Conservative party's attitude to climate change, the forthcoming UK general election, "green crap", the fifth carbon budget and fracking...

CB: As a Conservative peer and former minister, please can you explain the various dynamics and tensions at play within your own party when it comes to tackling climate change? You have the Lawsons and the Ridleys on the one side, and the Barkers and Rudds on the other. Why has it become such a problematic issue for certain sections of your party?

LD: I'm not sure that it has really in that sort of way. I mean, the truth is that the problem with climate change is that it demands a long-term solution, which is also a consistent solution. We're talking about cutting our emissions by 80 per cent by 2050. Now, for those for whom planning is a dangerous word because you want the market to work effectively and that what planning often does is to second guess the market and then find itself wrong. This concept of having to deal in the long term is simply very difficult to grasp and, of course, the considerable efforts of those who don't believe in climate change and to try to undermine the basic science has had its effect. It's becoming less and less, but it isn't instinctively something which people on the very extreme right find easy to accept.

In Part 2, Lord Deben discusses the UK's preparedness for climate change, the international climate talks, the need for a carbon intensity target, the Pope's encyclical on climate change and his use of Twitter...

CB: Is the UK prepared enough for the impacts of climate change in the years and decades ahead?

LD: No. No, not at all. It's a real issue, and it's not just the UK, it's throughout the world. There has been a dangerous dysfunction between adaptation and mitigation. The people for whom climate change is - as it is for me - the most material threat facing mankind, we have tended to focus on mitigation, because we can't see how we can achieve these ends without dealing with that. Some of those who are much less convinced, and some of those who are outright deniers, um, have been saying that you can do it all through adaptation. So they've almost tried to make a competitiveness between these two. And, oddly enough, our Climate Change Committee structure has made the links more difficult because, first of all, there is a separate chairman, perfectly rightly, of the adaptation committee, from the overall committee.
