McClatchy reported on a new NOAA sea level rise impact report and made some very good points. But a lot of the true meaning is left out.  “By 2070, the mid-range scenarios call for seas to be anywhere from 8 inches to 5.5 feet higher…

One of the biggest myths about climate change is that emissions reductions cool Earth. This is nowhere close to reality. Even the Paris Commitments of 80 percent emissions reductions by 2050 allow warming to triple by 2050 and quintuple by 2100.  We (the royal we)…

The IPCC changed their fundamental philosophy on how they evaluate scenarios of our future climate in their 2013 reporting, but they have yet to acknowledge the most common and meaningful way our climate usually changes, implying negative consequences for traditional climate reform strategies. Popular science…

Global Warming vs. Abrupt Change — What’s the Difference?

By | Abrupt changes, Antarctica, Arctic, Glaciers, Greenland, Gulf Stream, ice sheets, modeling, Sea Level Rise, West Antarctic Ice Sheet | No Comments

Something that is not clear in the overall climate discussion is that global warming is a radically different beast from abrupt change.  We hear abrupt change bandied about, but often it is not well defined. It appears to many that global warming is abrupt change…

Ice Loss During Antarctic Cold Reversal May Spell Trouble for WAIS Collapse

Fifty-two feet of sea level rise occurred in 400 years, 14,500 years ago with collapse conditions similar to today. We were coming out of the last ice age then, but then, forcing was thousands of times less than today. Our climate’s most meaningful and common…
