Below is a very brief summary of the conclusions from the climate scientists themselves -- those who believe in man-caused, catastrophic global warming.
- The globe warmed about 0.6o and the oceans rose about six inches in the last hundred years, according to the U.N. IPCC. (I use Celsius throughout unless otherwise noted.)
- We are now in what is called an interglacial period, or the time between ice ages. Previous interglacial peaks were three degrees warmer than now. In Antarctica, these previous peaks were actually six degrees warmer.
- Since the last ice age, the oceans rose about four hundred feet. Most of that occurred before the pyramids were built (and well before modern use of fossil fuels), but the trend for hundreds of years up to the present has been rising sea
- The sea ice of the south polar ice cap has grown in the last thirty years.
- Climate scientists have fairly recently recognized a climate cycle they now call the Atlantic Multidecadal Oscillation. "The cause of the oscillation is not well understood, but the cycle appears to come round about every 60 to 70 years." They think this is why temperatures over the last eight years or so do not show the continued warming their models predicted. This and other cycles (Pacific Decadal Oscillation, El Niño, La Niña) are not included in the IPCC climate models.
- The sun does appear to account for "at least 10 to 30 percent of global warming measured during the past two decades," according to two Duke University physicists. While they were quick to remind us "that their findings do not argue against the basic theory that significant global warming is occurring because of carbon dioxide and other 'greenhouse' gases," they note that IPCC-type climate models do not include any solar influences.
- The "ice caps" on Mars shrank over all three years of initial observation by NASA's Mars Global Surveyor and Odyssey missions, 2005-2007.
- Glaciers in the northern hemisphere generally have been shrinking for about seven hundred years, while those in the southern hemisphere have been shrinking for the last sixty-five hundred years. (You might notice that those times precede the modern use of fossil fuels.)
- Himalayan glaciers, 230 of the largest mid-latitude glaciers in the world, have been growing since at least 1980.
One could go on. Remember, these are the things that climate alarmists generally concede. So far, I see only slight warming and sea-level rise, nothing that looks unprecedented for an interglacial period, and nothing that looks unnatural. Everything is totally consistent with a planet that is near an interglacial peak and following cycles of various periods (from one year to 40,000 years) that are "not well understood."
