I sometimes imagine that the death of Global Warming alarmism is on the horizon. I dream of one day waking up and knowing that I won’t have to sit through another day filled with the terrifying fiction of the devastation that is soon to come because of “man made Climate Change.” Global Warming has now been “paused” for almost 20 years and still we have no relief from these alarmists in sight. Each day more scientists reject the concerns of the alarmists and yet the liberal media continues to pound the podium of irrational climate fear.
One day… one day we’ll live in a world where Global Warming is a thing of the past. Just something whispered in the retelling of not-so-fond memories…
The latest United Nations climate report is sounding the alarm on man-made global warming, saying that fossil fuels needed to be eliminated from the energy supply in the coming decades to avoid catastrophe.
“Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems,” reads the UN Intergovernmental Panel on Climate Change’s latest report.
“Decarbonizing… electricity generation is a key component of cost-effective mitigation strategies in achieving low stabilization levels,” the IPCC noted, adding that green energy needed to make up 80 percent of the world’s energy supply by 2050 and 90 percent by 2100 in order to kep temperatures from rising 2 degrees Celsius above pre-industrial times.
Despite the stark warning from the IPCC, some scientists have said the warning is not dire enough. The Washington Post’s Chris Mooney reported last week about scientists who thought the IPCC’s global warming predictions were too cautious. These scientists argue that the IPCC process can “lead to downplaying the full ranges of future scenarios.”
But while some scientists are saying the IPCC isn’t alarmist enough in its reporting on global warming, others argue that the UN climate bureaucracy is too alarmist in its predictions.
“The IPCC should be lowering their estimates of future impacts, most definitely not raising them,” Cato Institute scientist Chip Knappenberger told The Daily Caller News Foundation. “There is a major flaw in the IPCC [fifth assessment] (and all previous reports as well) in that the climate models that are used to produce all the scary climate projections are very likely, collectively, too sensitive to the buildup of atmospheric carbon dioxide.”
Knappenberger is referring to a measurement called “climate sensitivity” — referring to the estimated temperature rise from a doubling of atmospheric concentrations of carbon dioxide levels. Increasingly, scientists have been lowering their climate sensitivity measures as temperatures refuse to increase in two decades.
“Only desperate climate alarmists would have the gall to suggest the IPCC produces ‘conservative’ estimates of climate change in light of a growing mountain of evidence that the IPCC actually exaggerates potential climate change,” echoed Pat Michaels, director of Cato’s Center for the Study of Science.
Satellite temperature data shows average global temperatures have not displayed a warming trend in more than 18 years. This so-called pause in global warming has baffled scientists, who have offered dozens of explanations for why global temperatures have not trended upwards in nearly two decades.
“Sometimes, the smartest thing a forecaster can do is look out the window,” Michaels said. “Obviously, way too much warming has been and is being predicted.”
The IPCC has actually overestimated warming since 1950, according to Michaels. “It turns out that the average warming trend predicted for every period of record [1950-2013, 1951-2013, 1952 and others] are greater than what has been observed,” he said.
Scientists and environmentalists, however, have fired back at claims that climate models are running too hot by noting that surface temperature records show the last three decades have been hotter than any other on record. In fact, scientists predict 2014 is on track to be the hottest year on record globally.
Knappenberger noted, however, that even if 2014 is the hottest year on record, the observe average global temperature has been well below what climate models predicted.
Knappenberger wrote that “global warming fear-mongers point out that the average global temperature so far this year is a few hundredths of a degree higher than the previous record. Yet they fail to point out that the same temperature is more than two-tenths of a degree (about 10 times as much) below where it was supposed to be based on computer model projections of climate change resulting from the increase in greenhouse gases in the atmosphere.”
“They throw out statistics like ‘the 12 hottest years on record have come in the past 15 years.’ And yet never mention the fact that 15 of the past 15 years are cooler than their (obviously overheated) global warming predictions,” Knappenberger added.
