Climate Change Science Essay

Technical Rating: star
A Comprehensive Essay on Climate Change Science. This is a graphically intensive essay on most aspects of climate change with links to supporting data. Compiled by Ken Gregory. The sun is the main driver of climate change. Water vapor and clouds reduce the initial warming effect of CO2 missions.



NIPCC: Climate Change Reconsidered II - 2013-2014

Technical Rating: star
The reports by the Nongovernmental International Panel on Climate Change (NIPCC) provides the scientific balance that is missing from the overly alarmists reports of the United Nations' Intergovernmental Panel on Climate Change (IPCC), which are highly selective in their review of climate science. The report "Physical Science" shows that the warming due to CO2 emission will be modest and cause no net harm to the global environment or to human well-being. Negative feedbacks in the climate system reduce the model derived temperature sensitivity to values an order of magnitude smaller. Earth's surface temperature are largely driven by variations in solar activity, which may have contributed as much as 66% of the observed 20th century warming. - The report "Biological Impacts" shows that higher CO2 levels and warming enhances crop yields and has resulted in the greening of the earth.



Modulation of Ice Ages via Precession and Dust-Albedo Feedbacks

The slow wobble, or precession, of the axis of the Earth causes the "Great Year" because it gives warm and cool seasons over its approximate 23,000-year cycle. The advancing ice sheets during a "Great Winter" increases the Earth's albedo, reflecting sunlight and resisting the warming effect of the next "Great Summer". As the ice sheets grow and the seas cool, CO2 also reduces as it is absorbed by the oceans. Most plants suffer severe stress at 190 ppm CO2 and die at 150 ppm, because CO2 is a primary plant-food. The concentration finally reaches the critical 190 ppm level where world flora begins to die and the Gobi steppe-lands turn into a true sand desert. The ensuing dust storms dump thousands of tonnes of dust onto the northern ice sheets each year. The interglacial periods occur only every fourth or fifth Great Year. Ice core data shows that every interglacial warming period is preceded by about 10,000 years of intense dust storms. When the next Great Summer comes along, the dusty polar ice sheets can warm and melt and the next interglacial is born. Low concentrations of CO2 near the end of an ice age causes a die-off of plants leading to dust storms, reducing the ice sheet albedo, resulting in warming and the interglacial periods.



Editorial from Energy & Environment - July 2013

Technical Rating: star
This editorial from Dr. Arthur Rorsch and Dr. Peter Ziegler introduces the Special Issue of Energy & Environment which challenges the Anthropogenic Global Warming hypothesis and the projections of the IPCC. The set papers show that climate models fail to replicate past climate variations and "the frequency of extreme weather events has not increased during the last few decades." The authors write "the effect of variations in solar activity has been seriously underestimated by the IPCC."



Climate Change on a Watery Planet

Technical Rating: star star
This review of climate science by three Dutch scientists compares the hypothesis that anthropogenic emissions of greenhouse gases is the main cause of recent climate change to the hypothesis that the sun is the main driver of climate change. The paper shows that water plays an important role in stabilizing the climate through evaporation and changing cloud cover. The paper lists numerous discrepancies between the AGW predictions and observations. Changing solar ultraviolet radiation, and the flow of charged particles have a significant effect on atmospheric circulation and clouds.
