Great Intro To Ice Ages and Global Warming « Musings from the Chiefio

The case is made, and rightly so, that the only ‘tipping point’ is to the downside, back into a glacial period. The only looming catastrophe is death by ice. And there is bugger-all we can do to stop it. (Though the good part is that we probably have a couple of more thousand years of the present regime before things get bad, so plenty of time to contemplate it.)

Climate change complicates plant diseases of the future

Human-driven changes in the earth's atmospheric composition are likely to alter plant diseases of the future. Researchers predict carbon dioxide will reach levels double those of the preindustrial era by the year 2050, complicating agriculture's need to produce enough food for a rapidly growing population.

"Plants growing in a high carbon dioxide environment tend to grow faster and larger, and they have denser canopies," Eastburn said. "These dense plant canopies favor the development of some diseases because the low light levels and reduced air circulation allow higher relative humidity levels to develop, and this promotes the growth and sporulation of many plant pathogens."
