A new study co-authored by Francis Zwiers, the director of UVic's Pacific Climate Impacts Consortium, suggests that human - induced global warming may be responsible for the increases in heavy precipitation that have been observed over much of the Northern Hemisphere including North America and Eurasia over the past several decades.

Emanuel (2005) confirmed that hurricanes have grown stronger over the past several decades, in part due to human - caused global warming.

Internal variability can only account for ~ 0.3 °C change in average global surface air temperature at most over periods of several decades, and scientific studies have consistently shown that it can not account for more than a small fraction of the global warming over the past century.

Rather, it is because the warmth in these different regions was not synchronous, which means that when you average over the whole hemisphere, you get a broad, diffuse bump rather than the more dramatic spike we get over the past several decades when most places have warmed with a large degree of synchronicity.

Such models also indicate that warming would initially cause the Antarctic ice sheet as a whole to gain mass owing to an increased accumulation of snowfall (*; some recent studies find no significant continent - wide trends in accumulation over the past several decades; Lemke et al., 2007 Section 4.6.3.1).

As noted above, the role of carbon dioxide and other greenhouse gases as the primary driver for the warming the Earth has experienced over the past several decades is extremely well established.

According to Stone, cases where the link between human - generated greenhouse gas emissions and local warming trends were weak were often due to the fact that the climate observational record was insufficient in those regions to build a clear picture about what has been happening over the past several decades.

«And since it has long been known that the DTR has declined significantly over many parts of the world as mean global air temperature has risen over the past several decades (Easterling et al., 1997), it can be appreciated that the global warming with which this DTR decrease is associated (which is driven by the fact that global warming is predominantly caused by an increase in daily minimum temperature) has likely helped to significantly reduce the CHD mortality of the world's elderly people.»

There are two prominent and undeniable examples of the models» insufficiencies: 1) climate models overwhelmingly expected much more warming to have taken place over the past several decades than actually occurred; and 2) the sensitivity of the earth's average temperature to increases in atmospheric greenhouse gas concentrations (such as carbon dioxide) averages some 60 percent greater in the IPCC's climate models than it does in reality (according to a large and growing collection of evidence published in the scientific literature).

As the companion article to this one points out, virtually every major prediction of catastrophe that global - warming alarmists have made about the coming state of the environment over the past several decades — from melting sea ice and flooded nations to loss of snowfalls and increased climate refugees — has proven utterly incorrect.
