Think climate change is messy? Wait until geoengineering

Environmental News Bits

Someone’s bound to hack the atmosphere to cool the planet. So we urgently need more research on the consequences, says climate scientist Kate Ricke. Read the full story in Wired. Read more →

Science denial is still an issue ahead of COP28

Real Climate

In an unchanging climate, the random fluctuations would lead to warming in some parts of the world and cooling in others. In a world with just random local fluctuations but no climate change, about half the weather stations would show a (more or less significant) warming, the other half a cooling. Image: Prof.

A Nobel pursuit

Real Climate

Last week, the Nobel physics prize was (half) awarded to Suki Manabe and Klaus Hasselmann for their work on climate prediction and the detection and attribution of climate change. This came as quite a surprise to the climate community – though it was welcomed warmly. But let’s go back to the beginning.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

I followed with great interest the launch of the sixth assessment report Working Group 1 (The Physical Science Basis) from the Intergovernmental Panel on Climate Change (IPCC) on August 9th. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

We Crossed 1.5 C. Did We Breach the Paris Agreement?

Legal Planet

If you’re not a climate scientist—and maybe even if you are—reading news headlines this month has been confounding and a little scary. “In Climate Threshold ,” was the version at Forbes. language was added at the insistence of the highly climate-vulnerable small island states, who recognized that the previous target of 2.0

Getting physical with the climate crisis

Physics World

Long term, climate change is a greater threat than the COVID-19 pandemic. As air sunk through the atmosphere, it got squeezed and heated. Without human-induced climate change, that heat would be at least 150 times rarer. Politicians floundered despite half a million protestors marching through the Spanish capital.

Antarctic extreme events: ‘All-time records are being shattered not from decades ago, but from the last few years and months’

Frontiers

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. Prof Martin Siegert is an award-winning Antarctic glaciologist and climate scientist. The world’s largest ever heatwave (38.5C
