This is an easy to follow video on why rising greenhouse gases is a problem for the planet. We recently broke a climate record that has likely stood for about three million years. The daily mean of carbon dioxide hit 400 parts per million in early May, as measured by some very smart folks at the U.S. National Oceanic and Atmospheric Administration:
‘Before the Industrial Revolution in the 19th century, global average CO2 was about 280 ppm. During the last 800,000 years, CO2 fluctuated between about 180 ppm during ice ages and 280 ppm during interglacial warm periods. Today’s rate of increase is more than 100 times faster than the increase that occurred when the last ice age ended.’
It’s a big deal because as heat trapping gases rise, we can expect more extreme weather, meaning more dangerous droughts, hurricanes, tornadoes and cyclones.
