The United Nations has warned that Earth’s climate is now in a “state of emergency” as global warming speeds up and its effects grow stronger.
A new report from the World Meteorological Organisation said the past 11 years have been the hottest ever recorded, mainly because human activities are adding greenhouse gases to the atmosphere. The report found that last year was the second or third hottest year on record, with the world about 1.43C warmer than it was before large-scale industrial activity began. UN Secretary-General António Guterres said every major climate sign is “flashing red” and called for urgent action.
The report explained that extra heat is building up in the atmosphere and oceans while ice continues to melt. More than 90% of this extra heat is being absorbed by the oceans, which are warming faster and helping to push sea levels higher. Sea level rise is now close to five millimetres each year around the world. Scientists said this can increase the risk of flooding in coastal areas and make storms more dangerous.
Dr Lauren Vargo from Te Herenga Waka Victoria University of Wellington said the findings matched decades of scientific warnings. She said that although slightly warmer weather might sound pleasant to some people in New Zealand, the risks and costs are far greater than any small benefits. She warned that floods, heatwaves and wildfires are becoming more frequent and more intense. These events can damage homes, roads, nature and people’s health.
