The global warming limit set at the 2015 Paris Climate Summit is still possible, say scientists, but we need to redouble our efforts if the Earth’s atmosphere is to limbo under the ambitious boundary. In an article published today in Nature Geoscience an international team of climate scientists reports a re-assessment of complex Earth System Models. Crunching the numbers in light of new … Read More

James Dyke, University of Southampton By continuing to delay significant reductions in greenhouse gas emissions, we risk handing young people alive today a bill of up to US$535 trillion. This would be the cost of the “negative emissions” technologies required to remove CO₂ from the air in order to avoid dangerous climate change. These are the main findings … Read More

By Dr George Preddey In my 17th submission to all MPs and other worthies on Budget Day, 20 May 2015 (Budget Day), I suggested alternative proposals for New Zealand’s climate change INDCs (intended nationally determined contributions). These proposals dispensed with the pseudo-econometrics that characterised much of the discussion document and worked backwards from an essential goal of net carbon … Read More

I hadn’t quite understood New Zealand’s carbon emissions trading scheme before I moved to Wellington. The thing seemed a little dodgy with a fair bit of reliance on dubious foreign credits. But then the genius of the thing was explained to me. I’ve not looked at it properly myself, but the story is interesting, and seems plausible. It goes something … Read More

Steffen Böhm, University of Essex The Paris Agreement has mostly been greeted with enthusiasm though it contains at least one obvious flaw. Few seem to have noticed that the main tool mooted for keeping us within the 2℃ global warming target is a massive expansion of carbon trading, including offsetting, which allows the market exchange of credits between … Read More

Simon Lewis, UCL The UN climate talks in Paris have ended with an agreement between 195 countries to tackle global warming. The climate deal is at once both historic, important – and inadequate. From whether it is enough to avoid dangerous climate change to unexpected wins for vulnerable nations, here are five things to help understand … Read More

Andrew Glikson, Australian National University 2015 will likely be the hottest year on record, beating the previous record set only in 2014. It is also likely to be the first year the global average temperature reaches 1℃ above pre-industrial temperatures (measured from 1880 – 1899). Global warming is raising temperatures, and this year’s El Niño … Read More

I’ve been in Paris for over a week now, and the speed at which everything goes past, including time, is frightening. I think the 40,000 expected have now all arrived. I’m getting worried the only Eiffel Tower I’ll see is the one made of red folding chairs at the end of the “Champs Elysee” at the meeting. We began last … Read More

Paul N Edwards, University of Michigan The world’s nations are convening in traumatized Paris to hammer out commitments to slow down global climate change. Any long-term solution will require “decarbonizing” the world energy economy – that is, shifting to power sources that use little or no fossil fuel. How fast can this happen, and what could we do to … Read More
