Time for change. Migrating to a new site. (If only our forests had somewhere to migrate with a hospitable climate.) Back soon, sorry for the inconvenience. The Management

Dramatic Increase in Extreme Rainfall Events


Already, with just a single degree Fahrenheit of warming, the most extreme rain events have increased 40 percent across the Central U.S. including Texas. It’s not just our imaginations; it’s not natural cycles. Interestingly, some of it may be caused, or enhanced by, agricultural practices. Groisman et al. emphasizes that their work did not evaluate Read More →

PMP: Possible Maximum Precipitation – Climate Headroom


A 500-year storm today is the same as a 500-year storm in the past. It rains 8 inches in 6 hours. In our old climate, every year there is a 0.2 percent chance of a 500-year storm occurring. For a betting person the odds are 1:500. Projections are that by mid century 100-year events will Read More →

Merchants of Doubt Premieres in Austin: Melton to talk about $900 million annual climate change counter-movement

(See more on the Drexel/Stanford research on the climate change counter-movement here.) Merchants of Doubt, A film by Sony Pictures and Robert KennerAustin Premiere and Lecture by Bruce Melton PE Inspired by the acclaimed book by Naomi Oreskes and Erik Conway, MERCHANTS OF DOUBT takes audiences on a satirically comedic, yet illuminating ride into the Read More →

Temperature Pause 7: Unprecedented North Pacific Warming Ends Cool Phase


Whatever it has been that has kept the average global temperature from skyrocketing along with greenhouse gas concentrations is likely being overwhelmed. Of most significance is an unprecedented hot spot in the North Pacific that has probably signaled an end to the current cool phase of the Pacific Decadal Oscillation. Last summer’s global sea surface Read More →

Arctic Sea Ice Sets Lowest Winter Record


The National Snow and Ice Data Center (NSIDC) report on March 19, 2015 shows Arctic sea ice has reached its lowest winter minimum on record. The record only goes back to 1979, but conclusions can be drawn from the record and global temperature that show global warming at work. This interactive chart is the NSIDC Read More →

Unprecedented Drought Projections: Significantly Worse Than in the Last 1,000 Years in the American Southwest and Central Plains


The American Association for the Advancement of Science (AAAS), the world’s largest general scientific organization that produces the academic journal Science, has just begun a new open publishing journal; Science Advances (no paywall!). Their first issue includes a paper titled: Unprecedented 21st century drought risk in the American Southwest and Central Plains. Produced by researchers Read More →

Catching up


I will be posting several dozen reports over the next several weeks, back dated from recently to about last May when I became too busy to keep up. The priority of these posts has now reached a level that is above my other priorities, so here they come. For those of you who are subscribers, Read More →

Polar Vortex: February 2015 Temperature Departure


From the National Snow and Ice Data Center Website for March 4, 2015. There were four warm temperature state records set in February but surprisingly, no record cold state temperature records were set. There were 13 near-record cold state temperatures (2nd through 5th coldest) and three near-record warm state records (2nd and 3rd warmest). Read More →

Methane Eruption Craters: Lots of Them


Last summer the first of these appeared in the “formerly” frozen tundra of Siberia. When permafrost melts, methane can build up beneath impermeable soils and suddenly erupt. These holes are up to 100 feet wide and seven of them have been identified with many more smaller ones. Four of them have been located and three Read More →

Ice Lakes Advance on the Greenland Ice Sheet


Work from Leeds, Durham University, the Byrd Polar Research Center and University of California, Irvine, have taken a deeper look into melt lakes forming on the Greenland Ice Sheet. There modeling was for melt lake formation in the melt zone. The “melt zone” is that area around the edge of the ice sheet that melts Read More →

Hyperbole in Climate Activism: Beyond the Evolution of Mankind’s Civilization


I recently had the privilege of being the second reader on a thesis titled: Climate Change Virtue Ethics and Ecocriticism in Undergraduate Education, Barbara Krueger. Basically, this work evaluated the role of ethics and virtues in climate change education. To put the topic in my own words, to convey a chapter of climate change ethics Read More →

IPCC Underestimates Greenland Ice Loss


Greenland’s ice mass loss appears to be 22 percent more than 2013 IPCC suggests. The IPCC uses four major outlet glaciers to define Greenland ice mass loss. The most recent evaluation uses 130 glaciers and nearly 100,000 satellite laser altimetry points across Greenland. This work was published in the Proceedings of the National Academy of Read More →

Climate Change Outreach: Sensible and Logical

(Author’s note: Although this report focuses on the 18 to 25 year age bracket, these things appear to include communications techniques that are ageless.) From the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science we have a new detailed look at young people and climate Read More →

Maximizing Climate Change Outreach Post Extreme Weather


This study uses 1,008 survey participants to evaluate where extra effort should be applied to leverage  increasing awareness in climate issues after extreme weather events. Extreme weather has already increased because of warming in some circumstances (including cold weather extremes) and experiencing extreme weather increases climate change awareness of individuals. This work suggest using extreme Read More →

Greenland Ice Sheet Surge Movement and Melt Connection


This research, funded by the Swiss and U.S. National Science foundations, looked at Greenland Ice Sheet movement in the melt zone that extends inland 50 to 100 miles from the edge of the ice sheet. This is where melt water moves through the crevasses in the ice sheet, then flows down to bedrock and lubricates Read More →

Temperature Pause Part VI, Ocean Warming Underestimated


This installment discusses challenges with our ability to collect valid ocean warming data and how these challenges have systematically underestimated the role that our oceans have played in keeping our atmosphere cooler than the models say it should be. One thing that the climate deniers get right, maybe the only thing, is that we still Read More →

With This Decade’s Climate Policy, Expect More Warming Than if Nothing Was Done at All, by Bruce Melton


First Published on Truthout, August 27, 2014 (link) The fundamental climate change policy question today is not how much we should reduce carbon dioxide emissions by when, but what will currently proposed carbon dioxide emissions reductions do to our climate in the near-term? In addition, what are the ramifications of short-lived climate pollutants that are Read More →

Arctic Amplification Hits Greenland and US Northeast Hardest


The Arctic is warming more than twice as fast as the global average, Arctic sea ice and Northern Hemisphere snow cover are decreasing faster than the models project, more frequent extreme weather events are occurring and more frequent severe winters are occurring too. Three potential drivers  of these events are: changes in storm tracks, the Read More →
