There has been renewed talk in recent weeks about whether this summer’s scattering of extreme weather events is linked to anthropogenic climate change.
True, humans have altered the radiatively active portions of the atmosphere by adding greenhouse gases and aerosols. We’ve also altered the planetary landscape. These alterations are now part of the integrated global climate system that produces daily weather events—both extreme and benign.
So can our influence change the intensity of weather events? Yes.
Can it cause an event to happen that otherwise wouldn’t have? Conceivably.
Does it always act to make the weather more severe? No.
Are the changes detectable? Hmmm.
It seems that it is this issue of detectability that we often get hung up on. Otherwise, how do we know that human changes are having any impact?…
Robert Bryce continues to bear down on the failure of wind as a useful and beneficial source of utility-scale electricity, as shown in his recent Wall Street Journal article. (The full text is available on Bryce’s website and is provided below for convenience.)
In his latest book, Power Hungry; The Myths of ‘Green’ Energy and the Real Fuels of the Future, Bryce detailed the rationale underlying the inadequacies of renewables, especially wind, and their inability to make any worthwhile contribution to inexpensive, reliable electricity supply or “save the planet.”
Research into this topic is expanding (see this review of 2010 study by Peter Lang) beyond existing vague, high-level, general analyses that do not account for all the factors at play in integrating intermittent and volatile wind into an electricity grid.…
“I am not afraid about the climate.”
- Judith Curry, quoted in Alexandre Mansur, “American Researcher Says That There Is Still a lot of Uncertainty About Global Warming, Época, May 1, 2010.
“Real Climate, I think they’ve damaged their brand. They started out doing something that people liked, but they’ve been too partisan in a scientific way.”
- Judith Curry, quoted in Eric Berger, “Judith Curry: On Antarctic sea ice, Climategate and skeptics.” August 18, 2010.
There is solid middle ground in the ever-contentious climate-change debate. And now is the time to welcome it, given that politics is not going to reverse in any detectable amount the human influence on climate.
And the shame of the post-Climategate era is that other scientists like Curry did not join her to right the wrongs of a profession that has become politicized, agendacized, and Malthusiancized.…
