Runaway climate change could trigger 'Hothouse Earth' with 200ft sea level rises, warn scientists 

Earth may be on a runaway trajectory towards a ‘hothouse’ climate which will see huge swathes of the planet become uninhabitable and 200ft sea level rises, an international team of scientists has warned. A new review found that even if targets to cap global warming at 2C are met, it may already be too late because of a ‘domino effect’ of other factors such as the ongoing reduction in Arctic sea ice and the deforestation of the Amazon rainforest.
