As the air’s CO2 content continues to rise, nearly all of Earth’s plants should continue to exhibit increasing rates of photosynthesis and, as a result, increased biomass production. But what about plants that are suffering from various pathogen-induced diseases? Will they be able to reap the benefits of the many positive effects of atmospheric CO2 enrichment? We have previously investigated this possibility with respect to Earth’s trees and legumes. Here we do it for a number of other agricultural plants.

In light of the many recent observations, the prospect of earth’s corals being able to successfully cope with the possibility of further increases in water temperatures, be they anthropogenic-induced or natural, appears more than likely, if not altogether certain. Corals have survived such warmth -- and worse -- many times in the past, including the Medieval Warm Period, Roman Warm Period, Holocene Optimum, as well as throughout numerous similar periods during a number of prior interglacial periods; and there is no reason to believe they cannot do it again, if the need arises.

The EPA is effectively no longer under the control of the US Congress; its allegiance is to the UN and implementation of the policies of Sustainable Development via Agenda 21. It has considerable involvement in the IPCC reports and claims the UN body as a peer reviewed authority, in pursuing ever more rigorous controls of “CO2 pollution”, to bring about the realisation of “environmental governance”.

One of the great horror stories associated with predictions of CO2-induced global warming is that the warming will be so fast and furious that many species of plants will not be able to migrate towards cooler regions -- poleward in latitude, or upward in elevation -- at rates that are rapid enough to avoid extinction. This claim may sound logical (due to its extreme simplicity); but is it true?

Debris flows are a type of mass movement that frequently cause major destruction in alpine areas. Because debris flows are generally the product of heavy precipitation events, and because climate models project a future increase in the frequency and/or intensity of extreme precipitation events in consequence of CO2-induced global warming, many have become alarmed that such disastrous earthen flows will become more commonplace. In the present review, the likelihood of this claim is evaluated from three data-driven studies reported in the peer-reviewed scientific literature.

One of the perceived great tragedies of CO2-induced global warming is that rising temperatures will increase the development, transmission, and survival rates of parasites in general, leading to a perfect storm of biological interactions that will raise the prevalence of parasitic disease among animals in the future. But is this really so?

Global warming has been predicted by the IPCC to release long-sequestered carbon in Earth's peatlands to the atmosphere, possibly freeing enough of it at a sufficiently rapid rate to rival CO2 emissions from anthropogenic sources, with the end result of this scenario being a strong positive feedback to the ongoing rise in the air's CO2 content, which the IPCC contends will lead to further warming of the planet. But is this contention correct?

Dr Kerry Emanuel of MIT caused a storm recently, when he said in a Mother Jones video that, as a Republican scientist, he is almost ashamed to be an American, because not all Republican candidates have embraced Global Warming. An LA Times Op-Ed from January 5th 2012, portrayed him as the conservative scientist out to save the world.
In February last year, Dr Emanuel was playing the same “Republican scientist who believes in global warming” message in a radio interview for NPR. He brought in the usual mantras about the tobacco industry and a campaign of disinformation funded by vested interests, but failed to mention his own vested interest in the disaster insurance business.

Differences in pressure, or pressure gradients, cause wind. So, how does wind respond to rising temperatures? Several studies have addressed different aspects of this question in recent years.
