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 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 UN climate agency and the United Kingdom's Meteorological Office said there's a 75% chance that the average global temperature between 2026 and 2030 will be more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) higher compared to pre-industrial times. That threshold is the agreed-upon limit of warming – averaged over 20 years – set in 2015 by the Paris climate agreement.
