The Intergovernmental Panel On Climate Change (IPCC) was established in 1988 by the World Meteorological Organization and was sanctioned by the United Nations Environmental Programme’s governing council. For the past twenty years this consortium of the planet’s experts in climatology, meteorology and related disciplines has studied the world’s climate and the factors that contribute to its change.
The IPCC has released four “assessments” from 1990 to the most recent in February 2007. Each one is the result of study and review by world experts that passes any test of scientific authenticity and objectivity. The most recent finding, for which the IPCC was awarded a Nobel Prize, states, “Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level”
The opening section {1.1} of the summary report says,”Eleven of the last twelve years (1995-2006) rank among the twelve warmest years in the instrumental record of global surface temperature (since 1850). The 100-year linear trend (1906-2005) of 0.74 [0.56 to 0.92]°C is larger than the corresponding trend of 0.6 [0.4 to 0.8]°C (1901-2000) given in the Third Assessment Report. The temperature increase is widespread over the globe and is greater at higher northern latitudes. Land regions have warmed faster than the oceans”
BUT in an August 2nd letter to the editor of The New Haven Register Mark Schuler of Hamden, CT says, “I am becoming increasingly tired of the environmentalists’ agenda and alarmists’ screeds on global warming. There is no global warming.”
He adds with equal confidence that, “The average temperature of the planet has decreased over the last 10 years. There is more Arctic ice than at any point in the last 10 years. Any past or future warming cannot be proven to be caused by humans.”
The IPCC assessment continues, “There is very high confidence that the net effect of human activities since 1750 has been one of warming.
“Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG (human generated greenhouse gas) concentrations.
“It is likely that there has been significant anthropogenic warming over the past 50 years averaged over each continent (except Antarctica)
“During the past 50 years, the sum of solar and volcanic forcings would likely have produced cooling. Observed patterns of warming and their changes are simulated only by models that include anthropogenic forcings.”
Mark Schuler has a right to hold his uninformed and totally incorrect opinion on global warming. The Register has the right to publish that opinion. And since crazies generate more response than reasoned arguments it gets more people to read the paper. However, the bloviating of people with either elevated blood alcohol levels or onset of inflamed hemorrhoids shows a type of willful ignorance that is harmful to the efforts to make a better and safer environment for ourselves and our children and grandchildren. It is sad evidence that political entities with a ‘them vs us’ agenda can get individuals to act like intolerant idiots who think they are being noble in opposing the common good.
