UN issues dire warning over climate change destruction

The impacts of climate change are “heading into uncharted territories of destruction”, UN secretary-general António Guterres warned this week.

His comments follow the release of a multi-agency scientific report reviewing the latest research on the subject.

The report, led by the World Meteorological Organisation (WMO), warns that the world is “going in the wrong direction” on climate change.

With greenhouse gas concentrations continuing to rise in the atmosphere and world leaders failing to adopt strategies to hold global warming below 1.5 degrees Celsius above pre-industrial temperatures, the earth is inching closer to dangerous climate tipping points, the United in Science report says.

“Heatwaves in Europe. Colossal floods in Pakistan…There is nothing natural about the new scale of these disasters,” Guterres said.

Despite a dip in emissions during coronavirus lockdowns, planet-warming emissions have since soared beyond pre-pandemic levels. Preliminary data reveal that global carbon dioxide emissions in the first half of this year were 1.2% higher than during the same period in 2019, the report finds. Indeed, it says, the past seven years were the warmest on record.

The global average temperature has already warmed 1.1 degrees Celsius above the pre-industrial average. And scientists expect the annual average could be anywhere between 1.1C and 1.7C warmer up to 2026 – meaning there is a chance we could pass the 1.5C warming threshold in the next five years.  

By the end of the century, without aggressive climate action, global warming is estimated to reach 2.8C. 

The ocean current that moves heat from the tropics into the northern hemisphere, for example, is now at its slowest in 1,000 years – jeopardising historic weather patterns, says the report, which includes contributions from the UN Environment Programme and U.N. Office for Disaster Risk Reduction.

It adds that nearly half the world’s population is considered highly vulnerable to the impacts of climate change, including floods, heat, drought, wildfires, and storms. Also, by the 2050s, over 1.6 billion city-dwellers will regularly swelter through three-month average temperatures of at least 35C (95F), it adds.
