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

Scientists have been making projections of future global warming using climate models of increasing complexity for the past four decades

October 5, 2017 — These models, driven by atmospheric physics and biogeochemistry, play an important role in our understanding of the Earth’s climate and how it will likely change in the future. Continue reading Analysis: How well have climate models projected global warming

Explainer: How much did climate change ‘cost’ in the 20th century

From heatwaves to hurricanes, working out the dollar cost of climate change is a tough task. Often used by policymakers to weigh up the costs and benefits of tackling rising emissions, the topic is not without controversy. A recent study suggesting that human-caused climate change brought benefits in the 20th century offers a good starting point to explore a few of the issues that surround this fraught, complex topic.

March 1, 2017 — The research, published in the journal Public Library of Science, claims the world has experienced a “significant drop” in estimated climate impacts “since the late 1990s” and that Continue reading Explainer: How much did climate change ‘cost’ in the 20th century
