Like jt- not important.
Any rebuttal on the Grace sat error bars?
Guest post by Thomas Fuller
It is hard to understand many of those who are convinced that climate change will destroy civilization. Previous ideas about massive sea level rise or tipping points leading to unending temperature increases have been debunked. Conventional theory on climate change points to moderate temperature and sea level rises that can be dealt with using existing technology, although the sooner we start the easier it will be.
But for some, the need to believe (and to preach) about a coming catastrophe is so strong that they are willing to overturn their own theories to take temporary advantage of ephemeral observations that will support their apocalyptic vision of the future.
The Gravity Recovery and Climate Experiment has been an operational satellite mission since 2002, measuring differences in the Earth’s gravity. Pictures of our planet using GRACE look more like a partially deflated soccer ball than the pristine globe we’re more accustomed to seeing.
And according to some scientists working with GRACE measurements, Antarctica is losing ice. Not just the Western Antarctic Ice Sheet, which has been predicted to melt and succumb to mechanical pressure since the 1930s, but also the vastly larger ice sheet covering East Antarctica.
And sure enough, the ‘apocaholics’ are all over this, using it to reinforce their unrelenting drumbeat of doom-laden predictions of disastrous sea level rises.
But this is actually quite strange. According to climate change theory, ice should be increasing in Antarctica–the (very slight) increase in temperatures and the natural increase in precipitation should result in more snow over Antarctica which gets compressed into higher levels of ice. The same phenomenon is both predicted and observed in Greenland, by the way.
Instead of using this as proof of global warming, these people should be either wondering about the measurements or re-examining their theories. Because this is observed data working against the principles of their theory… But they cannot pass up the chance for a quick and easy headline that reinforces the ‘all disaster, only disaster, 24 hours a day’ routine.
