Global Warming Is Causing What Now?
What about energy output? Alarmists warned that hurricanes will become more powerful as the Earth warms, but the World Accumulated Cyclone Energy Index reveals the opposite. Worldwide tropical cyclone energy levels are now lower than at any time in the last thirty years. Hurricanes are getting weaker, not stronger. And tornadoes? Decreasing since the 1970s.
We live on a round planet. The sun heats the world unevenly because it is round. The Earth is cold at the top and bottom, hot at the equator. Storms exist to transport heat away from the tropics, keeping global temperature in check. It is the mission of storms to balance the Earth’s temperature, and the strength of storms depends on the magnitude of the temperature difference between the poles and the equator. This difference is greatest in the winter, when the North Pole can be 50 to 60 degrees below zero while the tropics are in the 80s and 90s.
A good way to witness how the atmosphere reacts to this difference in temperature is to watch the speed of the jet streams. These powerful rivers of wind seven miles above the Earth will triple in strength from summer to winter -- from about 60 miles per hour to 200 miles per hour or more. The same is true for winds on the surface. In the summer, the migratory storms move from west to east more slowly, with much less wind.
As temperature differences increase, storms work harder to transport heat around the world.
So, the warmists: they tell us that a warmer world will cause more severe storms, but there is no reason for this to happen. Global warming theory says the temperature changes will be most pronounced at the poles, much less so at the equator. As the temperature difference between the poles and the equator decrease, there will be less need for stronger storms.
We observe this weakening every year as the atmosphere transitions from winter to summer.
But should the small cooling trend we have witnessed since 2001 continue, we could see an increase in weather extremes in the future. A larger temperature gradient between the poles and the equator would mean the atmosphere would have to work harder to balance Earth’s temperature.
On the inside cover of Al Gore’s new book is a photoshopped hurricane off the east coast of Florida. The hurricane is rotating clockwise. This is impossible in the northern hemisphere -- the Coriolis effect makes all large-scale weather systems rotate counterclockwise north of the equator. As with the threats of higher temperatures and more severe storms, Al Gore and the alarmists have it backwards.
