Studies abound linking the increase in extreme weather-related catastrophes in recent decades, like droughts, floods, hurricanes and blizzards, to global climate change.
Some climate experts stress the urgency of addressing the problem now, predicting cascading economic and political, social and environmental upheavals worldwide if action is delayed. Since the dawn of the industrial revolution, the CO2 content of earth’s atmosphere has shot up from 275 ppm to over 400 ppm, already well above the 350 ppm limit some scientists believe is a safe level above which we risk triggering irreversible consequences out of human control.
Most Americans agree with the climatologists who believe that climate change is happening and likely caused by greenhouse gases produced by the burning of carbon-based fossil fuels. Asked if “the federal government should act to limit the amount of greenhouse gases U.S. businesses put out,” 78% said yes in a national poll which appeared January 20 in The New York Times. This reflects 60% of Republicans and 87% of Democrats polled.
