Science denial is still an issue ahead of COP28

Real Climate

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. And yes, also the increase in back-radiation towards the Earth surface from the CO2 greenhouse effect is a measured fact. It’s not hard to understand.

A Total Eclipse of the Heat

Legal Planet

Read out of context, that description fits climate change too, of course. Millions of us hopped planes, booked expensive AirBnBs, and made all sorts of detailed plans to be in exactly the place that scientists told them to be months ago. β€œ So why do so many ignore scientists’ predictions about climate change?!!”

Why Climate Scientists Are Sounding the Alarm on the Ocean Circulation System AMOC

Union of Concerned Scientists

Last month, 44 climate scientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. But what exactly would cause the AMOC to collapse?

Using Clouds to Fight Climate Change

But this simplified pathway misses a key step in cloud formation–and one that could help us combat climate change. Altering cloud properties influences Earth’s climate On sunny days, it’s clear that clouds leave shadows on the landscape. C above pre-industrial levels by 2100 to avoid the most severe impacts of climate change.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Solar activity provides no alternative explanation for today’s climate change Dagsvik and Moen claim that recent research indicates that variations in the sun’s magnetic field are of great importance for long-term fluctuations in solar activity. Our job is to be thorough and verify questionable results. It has taken time.

New Climate Research From a Year-Long Arctic Expedition Raises an Ozone Alarm in the High North

Inside Climate News

Warming of the surface of the Arctic is matched by a colder polar vortex high in the atmosphere, which is speeding the breakdown of the Earth’s shield against ultraviolet rays.

As climate scientists we tend to look at the IPCC reports a little differently than the general public might. Here are a few things that mark this report out from previous versions that relate to issues we’ve discussed here before: Extreme events are increasingly connected to climate (duh!) 1981) which can be seen here.
