WHAT'S ALARMING

“Global average temperature has increased by about 1.8°F from 1901 to 2016, and observational evidence does not support any credible natural explanations for this amount of warming; instead, the evidence consistently points to human activities, especially emissions of greenhouse or heat-trapping gases, as the dominant cause…Earth’s climate will continue to change over this century and beyond. Past mid-century, how much the climate changes will depend primarily on global emisisons of greenhouse gases and on the response of Earth’s climate system to human-induced warming. With significant reductions in emissions, global temperature increase could be limited to 3.6°F(2°C) or less compared to preindustrial temperatures. Without significant reductions, annual average global temperatures could increase by 9°F(5°C) or more by the end of this century compare to preindustrial temperatures.”*
