As extreme weather marked by tornadoes and flooding continues to sweep across Texas, Gov. Greg Abbott has requested – and President Obama has granted – federal help. I don’t begrudge Texas billions of dollars in disaster relief. After all, we’re all part of America. When some of us are in need, we all have a duty to respond. But the …
Permafrost thaw’s runaway effect on carbon release – Tim Radford
An international team of scientists has settled one puzzle of the Arctic permafrost and confirmed one long-standing fear: the vast amounts of carbon now preserved in the frozen soils could one day all get back into the atmosphere. Since the Arctic is the fastest-warming place on the planet, such a release of greenhouse gas could only accelerate global warming and …
Organic Farming Changes Agriculture from a Huge Carbon Source to a Carbon-DESTROYER
Approximately 35% of global greenhouse gases (GHGs) come from agriculture. Some argues that human can reverse global worming by sequestering several hundred billion tons of excess CO2 through regenerative, organic farming, ranching and land use. Increasing the soil’s organic content will not only fix carbon and reduce emissions, it will also improve the soil’s ability to retain water and nutrients …
Organic farming can reverse the agriculture ecosystem from a carbon source to a carbon sink
Approximately 35% of global greenhouse gases (GHGs) come from agriculture. Some argues that human can reverse global worming by sequestering several hundred billion tons of excess CO2 through regenerative, organic farming, ranching and land use. Increasing the soil’s organic content will not only fix carbon and reduce emissions, it will also improve the soil’s ability to retain water and nutrients …
Scientists show that long-term temperature rise is the inevitable consequence of increasing greenhouse gas emissions from fossil fuels. – Tim Radford
The so-called hiatus in global warming will probably make no difference to the world in the long run, according to Australian scientists. Using computer models to take the planetary temperature in 2100, they found that one set of models incorporated the slowdown, but others did not. In the end, the difference was barely significant: less than 0.1°C. The hiatus is …
Warming Climate May Release Vast Amounts Of Carbon From Long-Frozen Arctic Soils
More carbon is released into the atmosphere would amplify climate warming, and that, in turn, would cause more permafrost to thaw and release more carbon, causing the cycle to continue. Recent research by scientists has confirmed the suspicion scientists were making regarding the Arctic permafrost. Scientists estimate there is more than 10 times the amount of carbon in the Arctic …
Weather Modification: Myths and Facts
It is a safe bet to say that all progressive readers have some familiarity with conspiracy theories about weather modification. These theories, that range from “chemtrails” to the HAARP project, propose that sinister government and corporate forces are altering local weather and the whole globe´s climate with purposes that range from warfare to climate change mitigation. The most extreme version …
Canadian glaciers face drastic demise
By, Thomas Sumner April 6, 2015 Science News The Great White North may lose its glaciers faster than previously thought. A detailed physics simulation of how glaciers melt in a warming world show that Western Canada’s glaciers will shed 70 percent of their ice by 2100 relative to their 2005 volumes, researchers report online April 6 in Nature Geoscience. …
