WASHINGTON (AP) -- 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.
