I do not believe that the current warming trend is due to AGW.
The big issue on AGW, speaking for myself, is that it has become to sensational, examples:
-to hot global warming
-to cold global warming
-no rain global warming
-to much rain global warming
-above average hurricane season global warming
-average hurricane season global warming
-flooding global warming
-no flooding global warming
-good fishing season global warming
-poor fishing season global warming
I could go on for an hour, but I think you get my point.
Yeah, they seem to be talking points from Fox or talk radio. Let's address each of them briefly and have an actual conversation about them.
- Yes, global warming is causing and increase in overall temperature including heat waves.
- No, global warming does not cause cold snaps or winter weather, but it causes disruptions to weather patterns which can allow for regional cold snaps and winter weather. The severer winters that parts of the mid-West have been suffering through lately are not directly from global warming, but because the Polar Vortex is slipping out of it's normal location in the arctic. Meanwhile it's positively tepid in Alaska.
- Droughts can result from global warming, but droughts are more effected by regional weather patterns and geography. The Atacama desert in Peru has not been rained on in 20,000,000 years and most of that time was during an ice age.
- Increases in rain and snowfall on the other hand are more closely related to global warming because the warmer earth means the oceans are warmer and evaporate faster allowing more water vapor to cycle up to the atmosphere and out as snow and rain.
- No one claims that an average or less than average hurricane season is an indicator for global warming, and many Americans think that the Atlantic hurricane season is the entirety of tropical cyclonic activity in the world. There are four other seasons, east and west northern Pacific, southeastern Pacific and Indian Ocean.
Well for most of decade of the 70's science predicted another ice age, didn't happen. Scientist who supported the introduction of the metric system predicted the fall of the United States, and it would return the nation to the middle ages if we didn't do it.
Neither of those things ever happened. As far as the 70s ice age myth, that was a pop culture phenomenon based largely on a few newsmagazine stories and an In Search Of episode. An analysis of the climate research journal articles of the time shows a majority of them predicted warming.
