Environmental activists have relied heavily on computer models to predict climate patterns confirming their notion that mankind is toxic.
However, recent studies have shown models have failed to consider real world conditions in their calculations.
Exhibit 1 – Sea ice is more resilient to melting than thought:
Using new satellite data, researchers at University College London reported in Nature Geoscience on Monday that the total volume of sea ice in the Northern Hemisphere was well above average in the autumn of 2013, traditionally the end of the annual melt season, after an unusually cool summer when temperatures dropped to levels not seen since the 1990s.
“We now know it can recover by a significant amount if the melting season is cut short,” said the study’s lead author Rachel Tilling, a researcher who studies satellite observations of the Arctic. “The sea ice might be a little more resilient than we thought.”
Exhibit 2 – The effects of the vast deserts of the Earth have not been considered, and it appears that a good portion of emitted carbon dioxide is disappearing within them.
About 40 percent of this carbon stays in the atmosphere and roughly 30 percent enters the ocean, according to the University Corporation for Atmospheric Research. Scientists thought the remaining carbon was taken up by plants on land, but measurements show plants don’t absorb all of the leftover carbon. Scientists have been searching for a place on land where the additional carbon is being stored – the so-called “missing carbon sink.”
The new study suggests some of this carbon may be disappearing underneath the world’s deserts – a process exacerbated by irrigation. Scientists examining the flow of water through a Chinese desert found that carbon from the atmosphere is being absorbed by crops, released into the soil and transported underground in groundwater – a process that picked up when farming entered the region 2,000 years ago.
Underground aquifers store the dissolved carbon deep below the desert where it can’t escape back to the atmosphere, according to the new study.
The new desert study concludes that more study is needed… of course.
Many of the comments in the desert piece focus on the replacement of the technical name “carbon dioxide” with the word “carbon”. This switch is misleading, as the former co-founder of Greenpeace and climate scare-science skeptic, Dr. Patrick Moore, discusses in the following Prager University video:
Moore derides climate models in an wonderful article for Heartland, and he asserts that human emissions have been beneficial:
…My skepticism begins with the believers’ certainty they can predict the global climate with a computer model. The entire basis for the doomsday climate change scenario is the hypothesis increased atmospheric carbon dioxide due to fossil fuel emissions will heat the Earth to unlivable temperatures.
In fact, the Earth has been warming very gradually for 300 years, since the Little Ice Age ended, long before heavy use of fossil fuels. Prior to the Little Ice Age, during the Medieval Warm Period, Vikings colonized Greenland and Newfoundland, when it was warmer there than today. And during Roman times, it was warmer, long before fossil fuels revolutionized civilization.
The idea it would be catastrophic if carbon dioxide were to increase and average global temperature were to rise a few degrees is preposterous.
…Over the past 150 million years, carbon dioxide had been drawn down steadily (by plants) from about 3,000 parts per million to about 280 parts per million before the Industrial Revolution. If this trend continued, the carbon dioxide level would have become too low to support life on Earth. Human fossil fuel use and clearing land for crops have boosted carbon dioxide from its lowest level in the history of the Earth back to 400 parts per million today.
At 400 parts per million, all our food crops, forests, and natural ecosystems are still on a starvation diet for carbon dioxide. The optimum level of carbon dioxide for plant growth, given enough water and nutrients, is about 1,500 parts per million, nearly four times higher than today. Greenhouse growers inject carbon-dioxide to increase yields. Farms and forests will produce more if carbon-dioxide keeps rising.
Since Moore has become an environmental-activism apostate, Greenpeace has worked hard to demean his professionalism and undermine his work. Supporting better climate science would also get in the way of their anti-business protests featuring kayakers blocking ice-breakers on the way to assist Arctic oil drilling operations, which would then cut down on both drama and donations.
In conclusion, reliance on crazy climate models has lead to even crazier behavior.
