It is just like some colossally awful house-bidding process. Only here it is not just an attractive three-bed semi-detached residence that is at stake. In the run up to the United Nations Framework Convention on Climate Change (UNFCCC) Conference in Paris in December, each country is submitting its bargaining chip, a so-called Intended Nationally Determined Contribution (INDC).
The levels that countries put forward is part of the complex international climate negotiations – countries are keen to show genuine commitments to climate change action, but very few are willing to rush ahead of other nations.

Today the Lancet Commission on Health and Climate announced the release of their new report “2015 Lancet Commission on Health and Climate Change: Policy Responses to Protect Public Health”.
Following a first report released in 2009, which concluded that “Climate change is the biggest global health threat of the 21st century”, today’s report has a proactive, positive take-home: “tackling climate change could be the greatest global health opportunity of the 21st century.”
Strategically released following the 68th World Health Assembly held last month and in the lead up to the UNFCCC’s COP21, to be held in Paris later this year, the report is the culmination of a second international (predominantly Chinese-European) working group assembled to assess the health impacts of climate change and to identify and accelerate effective mitigation and adaptation policies over the next 5 years.

The term ‘sustainable development’ was first coined in 1987 in the UN’s World Commission on Environment and Development report, Our Common Future. Almost 30 years later, the concept of sustainable development is more relevant than ever.
The definition given in the report is, to this date, the most widely accepted modern definition of the term: ‘Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.’ Climate and society, energy, water, ecosystem health and monitoring, global health, poverty, urbanization, natural disasters, food, ecology and nutrition – these are some of the main problems that need to be tackled when discussing the possibility of sustainable development.
Professor Jo Haigh, Co-director of the Grantham Institute reports back from the Climate Parliament meeting in Lucerne, 12 June 2015.
I have just found a seat on the train from Lucerne to Zurich airport. It is absolutely packed, I suppose, with people going away for the weekend. Staring through the window at the snow-capped mountains, and having spent the day at an inspirational conference set by the beautiful lake, I am wondering quite why anyone would want to leave.
I have been at a meeting of the Climate Parliament. I only learned of this organisation recently but it is rather splendid – a group of legislators from across the world who are concerned about climate change and looking to influence governments to act.

Although both Labour and the Liberal Democrats have pledged to decarbonise the electricity sector by 2030, climate change is unlikely to be a key issue in the run up to the May general election. This reflects a long term decline in political engagement with the problem since the Copenhagen conference in 2009. Although Copenhagen was held in the immediate wake of the global financial crisis, the ongoing recession and drop in living standards have shifted priorities away from tackling climate change. The increasing cost of energy might also have hardened attitudes towards green policies.

China’s Energy Research Institute (ERI) releases an interesting analysis of the prospects for China’s energy production and consumption and CO2 emissions to 2050
Last November’s joint announcement of national climate targets by President Barack Obama and President of China Xi Jinping has framed the preparations for this December’s crucial Paris summit. The US is aiming to reduce its emissions by 26-28% below the 2005 level in 2025. China intends that its CO2 emissions will peak around 2030 and will use best efforts to bring that date forward.

This blog post by Samantha Buzzard, a NERC student at the University of Reading, is part of a series on Responding to Environmental Change, an event organised by the Natural Environment Research Council (NERC) funded Doctoral Training Partnerships at Imperial (SSCP), and the University of Reading and the University of Surrey (SCENARIO).
See the full list of blogs in this series here.
To conclude the Responding to Environmental Change meeting Matthew Bell, Chief Executive of the Committee on Climate Change, outlined the position of the UK in relation to climate change and the issues that could be faced at the Paris Climate Conference (COP 21) at the end of this year.

This week, the next round of UN negotiations on the Sustainable Development Goals (SDGs) are under way in New York. The SDGs aim to coordinate and promote development across the world in critical areas, including health, education, governance, and environment amongst others. Imperial College PhDs (myself included) recently exchanged ideas with David Hallam from the Department for International Development about his current work on the SDGs to be agreed later this year. The talk centred on how this ambitious global development effort could be successful and, very broadly, what role science and the environmental research being conducted at Imperial can play.

An agreement produced by the 20th Conference of the Parties in Lima, Peru, noted ‘with grave concern’ that countries’ current pledges on emissions reductions are insufficient to keep global temperature rise within either 2°C or 1.5°C of pre-industrial levels. This is indeed a serious concern because temperature changes of just a few degrees are enough to change the climate significantly. Rising sea levels, melting mountain glaciers and polar ice caps and increases in extreme precipitation have already been observed. These trends will continue with ongoing greenhouse gas emissions, and it is expected that we will continue to see an increase in extreme high sea levels, an increase in the intensity of the heaviest rain, and changes in the global distribution of rainfall.

This blog forms part of a series addressing some of the criticisms often levelled against efforts to mitigate climate change.
The Twentieth Session of the Conference of the Parties (COP 20) – the latest in a series of meetings of the decision making body of the UN Framework Convention on Climate Change –began in Lima this week. Many in the media are quick to point to the difficulty of obtaining international agreement on greenhouse gas emissions reductions, and to denounce COP 15, which took place in Copenhagen in 2009, as a failure.

This blog forms part of a series addressing some of the criticisms often levelled against efforts to mitigate climate change.
It is often claimed that intermittent renewable sources of electricity (mainly wind and solar photovoltaics), are too expensive, inefficient and unreliable and that we shouldn’t subsidise them.
What are the facts?
Last year, governments spent about $550 billion of public money on subsidies for fossil fuels, almost twice as much as in 2009 and about five times as much as they spent subsidising renewables (IEA, World Energy Outlook 2014). This despite a G20 pledge in 2009 to “phase out and rationalize over the medium term inefficient fossil fuel subsidies” that “encourage wasteful consumption, reduce our energy security, impede investment in clean energy sources and undermine efforts to deal with the threat of climate change”.

Owen Paterson’s remarks on the UK response to climate change miss the point. I do not disagree with him that the UK decarbonisation strategy should be improved. In particular, there is a need for a more effective strategy on energy demand. However, my preferred policy and technology mix would be very different to his and include the acceleration and expansion of the CCS commercial demonstration programme in order to reduce the energy penalty and overall costs of CCS. And without CCS, there is no way responsibly to use the shale gas he wants the UK to produce in the coming decades for electricity generation or in industrial processes, or any other fossil fuels.

A commentary published in Nature this week has opened up a discussion about the value of using the goal of keeping global warming to below 2°C.
David Victor and Charles Kennel are concerned that the below 2°C target for global warming is not useful, partly because they consider it is no longer achievable and partly because global mean surface temperature does not present a full picture of climate change. The problem comes, of course, in identifying an alternative approach to establishing what is required from attempts to mitigate global warming.
The 2 degree target is in a sense nominal, in that it there is no precise threshold at which everything goes from bearable to unbearable, but it does have the advantage of being easy to understand, for both policy makers and the wider public .

“Once more unto the breach, dear friends, once more”
Climate change was not, so far as I know, one of the issues that Shakespeare wrote about, despite plays like “The Tempest” or (for the sceptically minded) “Much Ado about Nothing”. But King Henry V’s lines in Act III of the play of that name could have been written for the UN Secretary General to deliver at the Climate Summit in New York on 23 September where, with the help of a VIP cast, he in effect also urged us to “stiffen the sinews” to address one of the defining issues of our age.
