Published in March, the IPPCâs AR6 Synthesis Report on Climate Change updates its predictions of the effects of temperature rises. It starkly concludes that those temperature rises will have a bigger impact at lower temperatures than previously predicted. Charlotte Edmond, writing for the World Economic Forum, picks out five charts from the report to illustrate the point: the range of likely temperature rises; global map of change in temperature, … [Read more...]
IPCCâs latest AR6 synthesis report lacks urgency and realism. Its own numbers say so
Kevin Anderson at the University of Manchester explains his deep disappointment in the recently released and influential IPCC AR6 synthesis report. Even the mainstream media criticised the lack of urgency in the language. Andersonâs objections go further. He says the reportâs own figures show net-zero must be reached by 2040, not the âearly 2050sâ as stated. Anderson goes on to criticise the modelling used as the standard, saying it is formulated … [Read more...]
IPCC Report on Adaptation: a rapidly closing policy window for climate change action
We do not know how successful we will be at cutting emissions. So âadaptationâ is how we change our behaviour, economies, infrastructure and planning to cope with the consequences of climate change. The IPCCâs 6th and latest report looks at the scientific evidence of climate risk and the adaptation solutions being pursued around the world. Alexandre Magnan at IDDRI summarises the findings. It says that by 2100 climate risk will increase two- to … [Read more...]
How multi-scenario âemulatorâ models are improving climate change projections
State-of-the-art Earth System Models (ESMs) simulate the flow of energy, moisture and chemicals through the atmosphere, ocean and land surface in unprecedented detail. But the data processing is so demanding that each scenario takes considerable time and expense to run, needing powerful supercomputers and teams of scientists and programmers to produce the models and analyse the results. âEmulatorsâ are much simpler models that can run on a … [Read more...]
