IPCC says ‘rapid and far-reaching’ measures required to combat climate change

June 15, 2018 — The world is on track to exceed 1.5°C of warming unless countries rapidly implement “far-reaching” actions to reduce carbon emissions, according to a draft UN report leaked to Reuters. Continue reading Leaked UN draft report warns of urgent need to cut global warming

Findings should not be seen as taking pressure off need to tackle climate change, authors warn

January 18, 2018 — Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study which, if correct, voids worst-case UN climate change predictions. Continue reading Climate sensitivity study suggests narrower range of potential outcomes

Scientists have presented a new, narrower estimate of the “climate sensitivity” – a measure of how much the climate could warm in response to the release of greenhouse gases

January 17, 2018 — The latest assessment report from the Intergovernmental Panel on Climate Change (IPCC) estimates that climate sensitivity is close to 3°C, with a “likely” range of 1.5 to 4.5°C. Continue reading New study ‘reduces uncertainty’ for climate sensitivity

Climate change was again placed at the centre of global diplomacy over the past two weeks as diplomats and ministers gathered in Bonn, Germany, for the latest annual round of United Nations climate talks

November 19, 2017 — COP23, the second “conference of the parties” since the Paris Agreement was struck in 2015, promised to be a somewhat technical affair as countries continued to negotiate the finer details of how the agreement will work from 2020 onwards.
