Britain’s children face life-threatening heatwaves that could leave thousands dead by the close of the century, the Royal Society has warned. If governments fail to tackle climate change by the year 2100, Britain’s heatwaves will increase three-fold. At present, approximately 2,000 people perish annually in the UK as a result of high temperatures, with the nation’s elderly population most at risk.
A sea level rise of 30cm by 2050 in New Zealand is "inevitable" and the country needs to prepare for it, the Parliamentary Commissioner for the Environment says. In the first of two reports on the impact of climate change, Dr Jan Wright issues a grim warning about the rising sea levels.
Meteorologists at the National Oceanic and Atmospheric Administration (NOAA) say the unusually high temperatures in the month of October have set new heat records, and it might just be the hottest October on record- beating previous heat records of October 2003. They say despite a bitter cold snap in America, this might be the hottest year ever on our planet. The weather agency in Japan also seemed to agree with this.

The complete melt of the Greenland ice sheet could occur at lower global temperatures than previously thought, a study in the journal Nature Climate Change showed on Sunday, increasing the threat and severity of a rise in sea level. Substantial melting of land ice could contribute to long-term sea level rise of several meters, potentially threatening the lives of millions of people.
“Our study shows that a temperature threshold for melting the (ice sheet) exists and that this threshold has been overestimated until now,” said scientists at the Potsdam Institute for Climate Impact Research and the Universidad Complutense de Madrid, who used computer simulations of the ice sheet's evolution to predict its future behaviour. A complete ice sheet melt could happen if global temperatures rose between 0.8 and 3.2 degrees Celsius above pre-industrial levels, with a best estimate of 1.6 degrees, the scientists said. Previous research has suggested the ice sheet could melt in a range of a 1.9 to 5.1 degree temperature rise, with a best estimate of 3.1 degrees.

One-twentieth of the world's ice is in Greenland, which is about a quarter of the size of the United States and about 80 percent of it is covered by the ice sheet. If it all melted it would be equivalent to a 6.4 meter global sea level rise, previous research has shown. "If the global temperature significantly overshoots the threshold for a long time, the ice will continue melting and not regrow - even if the climate would, after many thousand years, return to its pre-industrial state,” said team leader Andrey Ganopolski at the Potsdam Institute for Climate Impact Research. Today, global warming of 0.8 degrees has already been recorded.

“The more we exceed the threshold, the faster it melts,” said Alexander Robinson, lead-author of the study. If the world takes no action to limit greenhouse gas emissions, the earth could warm by 8 degrees Celsius. “This would result in one fifth of the ice sheet melting within 500 years and a complete loss in 2,000 years,” he said. “This is not what one would call a rapid collapse. However, compared to what has happened in our planet's history, it is fast. And we might already be approaching the critical threshold. If temperature rise is limited to 2 degrees Celsius, a complete melt of the ice sheet could happen in 50,000 years, the study found.
