Natural Climate Change Caused Problems

In a previous post I noted that warmist scientist Kevin Trenberth said Sandy was not proof of man-caused global warming, and a reader noted that Trenberth said that climate change is worsening some recent extreme weather events. Since I am not a natural climate change denier, as are Al Gore and many others, I agree with Trenberth: natural climate change has worsened many extreme weather events over millions of years. The worst drought in the US was in the mid-1930s when 24 of 50 state maximum temperature records were set; only 12 state record maximum temperatures have been set since 1960, and none in the 2000’s.

Other examples abound. Natural warming caused sea level to rise over 420 feet in 10,000 years since the end of the Ice Age, inundating much valuable pre-historical beachfront property. Vineyards in England thrived during the Medieval Warm Period only a thousand years ago, perished during the Little Ice Age (1350-1850 AD), and haven’t recovered since. Thriving Medieval Alpine villages were destroyed by advancing Little Ice Age glaciers, and are only now reclaiming their lost real estate just before the next Ice Age glaciers return.

Only 15,000 years ago Detroit and Chicago were under a mile of ice, making Detroit only slightly more habitable than now. During the much warmer than present Holocene Climate Optimum of 8,000 years ago, sea level was about 10 feet higher, and as the world has slowly cooled since then, the drop in sea level left many bustling ancient ports high and dry.

So yes, Kevin Trenberth, natural climate change has worsened some extreme climate events, and always has.
