Even if CO2 emissions slashed, we're still at risk of a 'Hothouse Earth'
by Abi Aldridge
What's Going On Here?
Dubbed ‘Hothouse Earth’ by scientists, new research suggests that a global temperature rise of just 2°C could result in irreversible changes to our climate. This case could leave areas of Earth completely uninhabitable.
What Does This Mean?
Our forests, oceans and land currently store huge amounts of carbon - in sea ice, permafrost, forests and glaciers. These natural feedback systems absorb carbon from the atmosphere which is pretty handy when we’re emitting so much of it!
Worse still, once one of these systems (detailed on the map below) are pushed to tipping point, this could cause a domino effect and take climate change completely out of our hands.
Why Should We Care?
But that doesn’t mean that we should stop our efforts and give up or accept defeat… Hothouse Earth isn’t inevitable and efforts to reduce carbon are already moving us towards a more ‘stable’ Earth. (Scientists behind the study are getting annoyed at defeatist media coverage!).
Hothouse Earth sounds pretty terrifying, but we shouldn’t listen to the defeatist stance taken by much of the media. Let’s take this as the push we need to reduce our carbon emissions.
