Richard Rothschild has just delivered a two part attack on climate change that seriously misrepresents the science and then claims that it's a communist plot to destroy capitalism. Really. You can't make this stuff up.
Mr. Rothschild claims that the belief in climate science is based on anecdotal assertions. There are scores of scientific agencies that claim that climate change is happening, man made and potentially destructive. Among them are the National Aeronautics and Aerospace Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), the National Climatic Data Center (NCDC) and the Intergovernmental Panel on Climate Change (IPCC). These are the most respected agencies in the field of climate science, hardly groups that would base their findings on anecdotal assertions.
Is current climate change man made or a natural occurrence? Studies show that the greenhouse gas CO2 is increasing at a rate never before seen in nature. Similarly, ocean temperature is increasing faster than ever recorded. The climate deniers thought they'd scored some points, claiming that the increase in air temperature was slowing. Science has two responses to this. First, NASA says the hottest years on record, going back to the 1880s, are 2014, 2010, 1998, 2013, 2007, 2009, 2002, 2003, 2006 and 2011. Second, it was not realized until recently that, to quote an IPCC report "Most of the additional energy stored in the climatic system since 1970 has gone into ocean warming. The remainder has melted ice and gone into the atmosphere."
Mr. Rothschild claims that there is no conclusive evidence. Air temperature and water temperature are going up, CO2 levels are going up, glaciers are melting, but conclusive evidence in a world full of variables may not yet be possible for the relatively new field of climate science. But I don't think that scientists should stay silent, given what they know and the trends they can measure.
As to political overtones, what I see is a bunch of people stating the obvious. There is so much money being made by the fossil fuel industry, they're going to fight like junkyard dogs to hang onto it. This isn't the commies trying to topple the free market; this is humans trying to survive.
