Torrential rains in some regions are causing massive floods while in other locales record droughts are occurring with higher frequency and severity.
Global food production is being hit hard, leading to large price increases and political instability. Areas under drought are experiencing massive forest fires of incredible ferocity. The frequency of extreme weather events has changed for the worse due to changes in the location, speed, and waviness of the jet streams which guide weather patterns and separate cold and dry northern air from warm and moist southern air.
The jet streams have changed because the equator to north-pole temperature difference has decreased due to the huge temperature rise in the Arctic. This temperature rise in the Arctic is due to a decrease in the area of highly reflective snow and ice, which is caused by melting. The melting is from warming due to the increase of greenhouse gases from fossil fuel burning.
The Arctic sea ice and spring snow cover will vanish within a few years and the weather extremes will increase at least 10x. - Paul Beckwith, June 20th, 2013.
What can you do? Talk to your politicians and friends about climate change and the need to slash fossil fuel emissions. Immediately. Cut and paste my comments above and post them on facebook, send them to newspapers, and educate yourself on the science behind global climate change. Leave my name on or take it off and plagiarize all you want, just get this knowledge out ...
