Some occasions are so excessive they might haven’t have occurred with out local weather breakdown, in different areas there’s a development of accelerating frequency/severity. These occasions, alongside a lot worse predictions by scientists, must be sufficient to push world leaders into motion on local weather. However at greatest we see solely half-measures and delay. Lower than 100 days stay till the COP26 summit, and the UK authorities is issuing new oil drilling licences whereas ignoring the hole between its emissions targets and a scarcity of insurance policies to fulfill them. We’ve got to talk out and make sure the voices of these on the entrance strains of local weather change are heard.
Heatwaves, drought and hearth
Madagascar

Trigger and impact
The hyperlink between local weather change and heatwaves is clear, however there’s additionally a transparent mechanism linking international warming to excessive rainfall occasions: hotter air can maintain extra moisture.
It was seemingly compulsory to finish experiences on excessive climate disasters with a disclaimer “No single occasion will be stated to be attributable to local weather change.” We’re previous that now. For instance, researchers estimate local weather destabilisation made the North American heatwave 150 times more likely.
The extra excessive it’s, the extra possible it’s {that a} catastrophe would merely not have occurred with out the planetary experiment of altering our environment. For different occasions, they’re inside a ‘regular’ vary, and will have occurred with out local weather change. However with local weather change loading the cube, excessive climate occasions grow to be extra frequent and extreme. A latest research discovered that more than a third of all extreme heat deaths worldwide can be attributed to climate change.
