“In the past two centuries, many people have hypothesized that the solar irradiance at the top of the Earth’s atmosphere varies. Recent satellite measurements confirm that such variations exist.” – Hoyt and Schatten, NASA Goddard
Their conclusion is that 71% of current climate change can be modeled from just 50% of the solar irradiation changes over the last three centuries. Just half.
“Over a time span of 1,000 years, we found that volcanic eruptions generally correspond with enhanced ice sheet melting within a year or so. . . present day ice sheets are potentially very vulnerable to volcanic eruptions.” – Columbia University’s Lamont-Doherty Earth Observatory
Their conclusion is that the frequent and intense eruptions in the 1990s and into this millennium could be sufficient to melt the arctic ice sheet.
Both articles go on to speculate how anthropogenic causes could affect these natural phenomena. Why would they need to add “man made” to the entirely sufficient organic mix? Because funding is consistently only paid for, and publication only available to, bad news due to man. It really is that simple.
The NASA publication asserts their data has a “95% confidence level. To understand our present climate variations, we must place the anthropogenic variations in the context of natural variability from solar, volcanic, oceanic, and other sources.”
The Columbia paper, in turn, speculates that “some might suggest” diminishing ice could cause this increased vulcanism due to loss of weight on the landmass. Of course some might.
Many journalists stay up nights thinking of creative ways to force research into condemning and terrifying continuations of the terror. I found this one: “New NASA research has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover.” What? Does this mean sea ice is returning? I do believe it does, and so the record shows.
To really understand this, recognize that 70% of sea ice is seasonal. There has indeed been a series of “big thaws,” but those are offset by a series of “big chills” that “could slow down the extinction of sea ice for decades, or even centuries.” Could, yes. It could mean we’ll all die this summer when the average global temperature climbs to 90° Celsius.
You can report that I said that.
