WASHINGTON — In the next five years, the Earth is overwhelmingly likely to surge again and again past the international climate threshold set as safe and shatter its hottest-year record along the way, according to new United Nations climate projections.

The World Meteorological Organization (WMO) also forecasts an overheating Arctic that warms nearly 3 degrees Fahrenheit (1.66 degrees Celsius) between now and 2030 and a dangerous drought with potential wildfires for the Amazon, a crucial part of Earth's natural defenses to lessen human-caused climate change. A hotter globe from the burning of coal, oil and gas means more extreme weather including floods, droughts and heat waves, scientists said.

The projections by the U.N. climate agency and the United Kingdom's Meteorological Office said there's a 75 percent chance that the average global temperature between 2026 and 2030 will exceed 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times. That threshold is the agreed-upon limit of warming — averaged over 20 years — set in 2015 by the Paris climate agreement.

A U.N. science report a few years later detailed how exceeding that 1.5 mark means more likely death, danger and species loss. Even though it's only a few tenths of a degree, some of the planet's ecosystems, such as coral and glaciers, can't handle the strain.

Passing warming limit has consequences, but no cliff

There’s a 91 percent chance that at least one of the next five years will shoot past the 1.5 degree threshold and an 86 percent chance that one of those years will smash the record for Earth’s hottest year set in 2024, the WMO report said. The WMO projects each year between now and 2030 to be between 1.3 degrees Celsius (2.3 degrees Fahrenheit) and 1.9 degrees Celsius (3.4 degrees Fahrenheit) since the late 1800s.

“It’s important to note that (1.5) is not kind of a cliff edge that we’re going to fall off,” said report co-author Melissa Seabrook, a climate scientist at the U.K. Meteorological Office. “Every kind of 0.1 of a degree has more and more severe impact.”
