Apparently a handful or so "clueless geriatric" engineers and astronauts from the Apollo days (not climate scientists) have got together and are publishing some anti-science propaganda about climate. While they generally agree with the fact that humans are causing global warming, they want to delay action. They are merchants of doubt and therefore climate science deniers.
(Putting this into perspective, if this survey is any guide, at least 300,000 or more who worked on the Apollo missions, including thousands of engineers, scientists and astronauts, accept and respect climate science.)
To save you reading their gumf, here's a summary:
Global warming is happening, by the way plants love CO2, and it's caused by burning fossil fuels but it might not be all bad and plants love CO2 and sea levels will rise but there's still time and it might be caused by us old fossils and whatever, but we shouldn't start to do anything about it yet because not 100% of everything is 100% known yet and because we're still alive and we don't like taxes and anyway plants love CO2. Did we say plants love CO2? (mumble mumble.... where did I put my dentures?.... did someone remember to put in the bit about plants loving CO2?...I can say how I hate government now that it pays me a generous superannuation instead of a salary ... mumble mumble)Yeah, right! Plants might love CO2 but they don't like drought or extreme heat waves or floods or shifting seasons or wildfires or losing their bird and insect pollinators or shifting plant zones. Plants can't walk away when conditions get too uncomfortable. They can't move uphill when it gets too hot if they are already at the top of a mountain.
In support of their 'case' to delay responsible action, about the only people these retired engineers seem able to trot out are Richard Lindzen (who has tried but failed to show low climate sensitivity) and Roger "not a climate scientist" Pielke Jr. who agrees that humans are causing global warming but is reluctant to do much about it mainly, as far as I can make out, for unfathomable ideological reasons of his own.
Thousands of climate scientists vs a dozen denying engineersThere's no mention of the fact that 97% of the thousands of climate scientists, and other scientists whose research work relates to climate, agree that humans are causing dangerous climate change by burning fossil fuels and other activities. Or that if we don't start acting now, the consequences will be dire.
Me? I'll go with the 97%. This is the Critical Decade.
Stick with the specialistsThe astronauts are lucky the Apollo missions were managed by specialists in rocket science and space exploration.
Who are you going to call on to find out about climate science? We can thank our lucky stars that climate science is done by climate scientists, not retired engineers and rocket scientists who know nothing about climate.
