Detailed regional data reduce warming-drought link doubts

by Andy Extance in Simple Climate

In Portugal and Spain climate change has already driven over 2°C of warming in summer, and new findings from Sergio Vicente-Serrano from the Pyrenean Institute of Ecology are dispelling uncertainties that the temperatures are making drought more severe and widespread. ... Read more »

Climate sensitivity wrangles don’t change the big picture on emissions

by Andy Extance in Simple Climate

Modelling studies from Joeri Rogelj at the Swiss Federal Institute of Technology, ETH Zurich show we still need to release fewer greenhouse gases even if the world does warm more slowly in response to them than today’s best estimates suggest. ... Read more »

Fairness instinct trumps economic expectations on climate costs

by Andy Extance in Simple Climate

Students taking the role of rich countries in climate negotiation games make generous offers to pay towards the cost of cutting greenhouse gas emissions on fairness grounds, finds Robert Gampfer from ETH Zurich, who suggests that governments doing the same might get popular support. ...

Real-world grounding could cool 21st century outlook

by Andy Extance in Simple Climate

Initialised decadal predictions, the middle ground between weather forecasting and climate modelling, get closer to simulating the current warming slowdown than uninitialised ones do, NCAR climate scientists Jerry Meehl and Haiyan Teng have shown. ... Read more »

Is our weird weather linked to climate change? Oddly, sport can show us the score.

by Andy Extance in Simple Climate

Though extreme events can happen by chance, our emitting CO2 is changing the odds, like match-fixing does in sport – and the climate stakes are too high not to realise this. ... Read more »

Heat drives Pakistani migration

by Andy Extance in Simple Climate

As floods don’t impact farming income like high temperatures does, according to Valerie Mueller from the International Food Policy Research Institute (IFPRI) in Washington DC and her colleagues, perhaps some aid money should go to developing more heat-resistant crops to prepare for further climate change. ...
