How to deal with the impact of climate change is front and centre at international climate talks in Warsaw, with a fund for “losses and damages” caused by climate change to developing nations on the table…
While they’re very pretty to look at, museum collections are also valuable to science. Curious Expeditions

Right at the museum: collections give clues on climate change

We know museums attract visitors who come to view and wonder at their vast array of displays, but they are also used by expert researchers – locally and abroad – who make use of the ever-growing collections…
Using tree measurements by Papua New Guinean villagers such as Daniel and Jackson, scientists can estimate that this tree stores about one tonne of carbon in its trunk and branches. Michelle Venter

How tree huggers can save forests with science

While hugging a tree sounds relaxing, it’s harder than you might think - especially when the tree is 20 storeys high and 3 metres wide, it’s hot as hell, and you’re swatting away swarms of sweat bugs…

Climate change and aerosols: new research

New research published today in Nature gives us a better idea of how much aerosols produced by people are influencing climate change. Aerosols — tiny particles produced naturally and by burning fossil…
What is the relationship between carbon dioxide and temperature rise? Werner Wittersheim

Explainer: what is climate sensitivity?

Humans are emitting CO2 and other greenhouse gases into the atmosphere. As these gases build up they trap extra heat and make the climate warmer. But how much warmer? Scientists have long understood that…
A lot of people have made a lot of promises about reducing emissions, but what do they actually mean? UN Climate Change

Making sense of chaotic emissions reduction pledges

The idiosyncratic nature of pledges by countries to stem their greenhouse gas emissions is an indicator of the chaos that characterises international climate change policy. The countries that have quantified…
