While the IPCC and global warming alarmists continue to claim climate change is controlled by atmospheric CO2 levels, most knowledgeable scientists will tell you that climate change is caused by variation in Earth's orbit and orientation. These periodic changes in movement and attitude are called the Milankovitch Cycles. A new paper, to be published in Science, confirms that glacial terminations are caused by Earth's orbital cycles, not carbon dioxide.
In a stunning paper in Science, researchers claim to have reversed the impact of clouds on global climate. It has long been known that low level cloud cover creates a net cooling effect on climate. This new study, which concentrated on a restricted area of the Pacific Ocean, claims that warming oceans reduce low cloud cover letting in more sunlight that further warm the ocean and hence provide a positive feed back that adds to global warming. Based on a warming episode that started in 1978, the article claims that observational analysis showed that clouds act as a positive feedback in this region on decadal time scales. But a cometary on the article in the same issue of Science says that the analysis suggests—but falls short of proving—that clouds are strongly amplifying the warming. If it's true, then almost all climate models have got it wrong.
In a five-part video series featuring Danish scientist Henrik Svensmark, the author of The Chilling Stars talks about his research into the effects that cosmic rays have on cloud formation. His theories contradict the IPCC’s theory of anthropogenic global warming, which basically blames last century's rise in average global temperature on human CO2 emissions. As many good scientists outside of the inbred climate change community have noticed, carbon dioxide just isn't up to the job of causing last century's observed global temperature rise. Instead, Svensmark and his colleagues hypothesize that clouds created by cosmic rays, which are in part controlled by the activity of the sun, regulate Earth's climate. Because this contradicts the IPCC's view of global warming, Svensmark's theory has been ignored by the climate alarmists and Svensmark himself vilified.
For many years the Committee for Skeptical Inquiry (formerly CSICOP) has published the Skeptical Inquirer, a magazine dedicated to rational thought and a scientific view of the world around us. Mostly concerned with debunking pseudoscience and mystical beliefs, its articles mostly concerned UFOs, bigfoot sightings, psychic spoon benders and spirit mediums. Now, unfortunately, it seems they have allied this previously skeptical magazine with one of the biggest scientific scams of our time, anthropogenic global warming.
The formation of low-level clouds—clouds that have a cooling effect on Earth's climate—has vexed climate scientists for years. Current climate models treat cloud cover simplistically and make the assumption that cloud cover decreases as temperatures rise. New data from a cloud sampling experiment indicates that biological material—bacteria, spores and plant material—may account for 1/3 of the airborne material involved in cloud formation. Furthermore, biological material can form clouds at much warmer temperatures than mineral dust. These new discoveries indicate that modelers have the effects of temperature on low cloud cover backwards, placing all model predictions in doubt.
The evidence is in, observations and models show that northern tropical Atlantic surface temperatures are sensitive to dust blowing in from North Africa. Regional changes in stratospheric volcanic and tropospheric mineral aerosols (i.e. dust) are responsible for 69% of the upward trend in temperatures over the last 30 years. Once again a new factor has been discovered that is not accounted for in general circulation models (GCM) used to predict global warming—and once again the importance of CO2 is diminished.
Two computer modelers from CMU have written a program to simulate the interaction of cosmic rays with Earth's atmosphere. Because the model failed to predict significant increases in cloud cover, global warming activists are claiming the theory linking cosmic rays to climate change has been discredited. Climate models have failed to accurately predict the current downward trend in temperatures and now we are asked to accept a model as proof of how the Universe works. In truth, the paper cited is nothing more than a study of a computer program, and has nothing to do with the physical reality of how Earth's climate functions.
NASA researchers report that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles called aerosols. Though greenhouse gases are invariably blamed for global climate change, and the shrinking Arctic ice cover in particular, this new research indicates that as much as half the warming in the Arctic can be attributed to sort lived particulate pollution—basically soot. Unlike the dreaded gas, CO2, aerosols do not stay in the atmosphere very long, suggesting that the effects of any warming caused by aerosols would quickly be reversed if their emissions ceased.
Most everyone has heard the recent announcement that Global Warming has been put on hold for 20 to 30 years. Earth's variable climate continues to make fools of climate scientists, obstinately refusing to follow the IPCC's climate change script. Why? Because the climate change doomsayers put their faith in computer models, not in hard science.
Eclipsed by the pageantry of the 2008 Beijing Olympics and Russian attempts to start WWIII by invading their former client states, is a noticeable downward trend in global temperatures. Data from the UK Meteorology Office shows that temperatures in the first half of the year have been cooler than any year since 2000. The reason given for the cooler temperatures is the natural cycle of La Nina and El Nino periods, which affect climate world wide.
