A paper titled "Global Warming: A Geological Perspective" published in Environmental Geosciences, and summarized below in Arizona Geology, should be required reading for all climate scientists. The paper notes that if "the temperature increase during the past 130 years reflects recovery from the Little Ice Age, it is not unreasonable to expect the temperature to rise another 2 to 2.5 degrees Celsius to a level comparable to that of the Medieval Warm Period about 800 years ago".
New paper confirms findings of Lindzen & Spencer of very low climate sensitivity to CO2 A paper under review for Earth System Dynamics uses a novel technique based on satellite data and surface air temperatures to find that global warming due to increased CO2 is much less than claimed by the IPCC. According to the author, the findings confirm those of Spencer & Braswell and Lindzen & Choi that a doubling of CO2 levels would only lead to an increase in top of the atmosphere temperature of 0.67°C, or global surface temperature of about 0.18°C, instead of the alleged 3°C claimed by IPCC computer models.
Paper finds the Sun controls climate & 'gives no support to theory of anthropogenic climate change'
A paper published in the Journal of Geophysical Research finds temperatures in the troposphere behave similarly to changes in solar activity over short timescales and a "cumulative negative [not positive as claimed by climate alarmists] feedback in the Earth climate system governing the tropospheric variability during the last 22 years." According to the paper, "The result emphasizes a dominating role of the solar irradiance variability in variations of the tropospheric temperature and gives no support to the theory of anthropogenic climate change," and "Increasing concentration of greenhouse gases in the Earth atmosphere appeared to produce too weak forcing in order to dominate in the Earth climate system."
