Climate change is real and it's getting worse. Global temperature averages are creeping upward, seas are warming, rising and becoming more acidic, and extreme weather events such as droughts, wildfires, floods and powerful storms are becoming more common. The threat is so great that humanity must act now to defuse what United Nations scientists call a "climate time bomb" which, if ignored, will yield "untold suffering."
At Live Science, our expert writers and editors cover the impact of global warming, and the measures that scientists, world leaders and innovators are taking to reduce our harmful impact on the planet, with the latest climate change news, features and articles.
