Time Is Running Out to Avert a Harrowing Future, Climate Panel Warns

The dangers of climate change are mounting so rapidly that they could soon overwhelm the ability of both nature and humanity to adapt, creating a harrowing future in which floods, fires and famine displace millions, species disappear and the planet is irreversibly damaged, a major new scientific report has concluded.

The report released Monday by the Intergovernmental Panel on Climate Change, a body of experts convened by the United Nations, is the most detailed look yet at the threats posed by global warming. It concludes that nations aren’t doing nearly enough to protect cities, farms and coastlines from the hazards that climate change has already unleashed, such as record droughts and rising seas, let alone from the even greater disasters in store as the planet keeps heating up.

Written by 270 researchers from 67 countries, the report is “an atlas of human suffering and a damning indictment of failed climate leadership,” said António Guterres, the United Nations secretary general. “With fact upon fact, this report reveals how people and the planet are getting clobbered by climate change.”

In the coming decades, as global temperatures continue to rise, hundreds of millions of people could struggle against floods, deadly heat waves and water scarcity from severe drought, the report said. Mosquitoes carrying diseases like dengue and malaria will spread to new parts of the globe. Crop failures could become more widespread, putting families in places like Africa and Asia at far greater risk of hunger and malnutrition. People unable to adapt to the enormous environmental shifts will end up suffering unavoidable loss or fleeing their homes, creating dislocation on a global scale, the authors said.

To avert the most catastrophic impacts, nations need to quickly and sharply reduce emissions of carbon dioxide, methane and other greenhouse gases that are dangerously heating the planet, the report said.
