Growing glaciers, missing heat and ethanol

15 July 2011
Climate change

At www.physorg.com/print229770933.html we have a new study in Environmental Research Letters July 5th that claims it will get hotter even than the extravagant claims made by the IPCC – all down to modelling efficiencey. At http://wattsupwiththat.com/2011/07/12/the-grass-is-greener-on-the-ethano…  … another story common to a lot of sites (such as www.physorg.com/print229685676.html) and concerns agriculture's contribution to AGW. The Midwest has been a source of greenhouse gases for years, we are informed, and it is recommended that perennial grasses replace corn as used in ethanol production. The study of course used a computer simulation and was published in Frontiers in Ecology and the Environment and was conducted without consulting anybody living in the real world, such as farmers, and completely ignored the fact that ethanol crops had replaced the growing of food crops which might just cause shortages. Even greenies have to eat. 

Meanwhile, at www.physorg.com/print229870401.html we learn that although glaciers can shrink in response to global warming they can also grow at a remarkable rae during cooling events – such as the late 18th century. This is of course stale news – HH Lamb was saying the same thing 50 years ago. However, this study has gone further in that scientists have actually measured the shrinkage and growth rates – on the ground.
