Yet another study showing how much hotter the Earth could get has emerged.
Scientists took dozens of rock samples from deep beneath the ocean to look at levels of carbon dioxide in the atmosphere in the past. They combined this with data from climate models to estimate the effect on surface temperatures up to 2 million years ago. The results suggest that we may be underestimating the current rise in global temperature.
I hope this acts as another serious reminder of the huge challenge we are facing with climate change. How many more studies are needed until we start to act and minimise the potential damage?
