UN warns world unprepared for risks from climate change

Members of the UN’s climate panel say it provides overwhelming evidence of the scale of these effects. Natural systems now bear the brunt, but a growing impact on humans is feared. Our health, homes, food and safety are all likely to be threatened by rising temperatures, the summary says.

A United Nations panel on Monday said that the effects of climate change are already being felt across the globe, warning in a major report that they will likely be “severe, pervasive, and irreversible” in the years to come.
