Polar bears are the perfect symbol of global warming, with some experts predicting their extinction in the wild by 2050.
The evidence that human activities are responsible for global warming is stronger than ever, according to a review of 110 research papers on climate change by the U.K. Met Office, Britain’s national weather service.

A review from the UK Met Office says it is becoming clearer that human activities are causing climate change.
It says the evidence is stronger now than when the Intergovernmental Panel on Climate Change carried out its last assessment in 2007.
The analysis, published in the Wiley Interdisciplinary Reviews Climate Change Journal, has assessed 110 research papers on the subject.
It says the Earth is changing rapidly, probably because of greenhouse gases.
