Are the glaciers in Glacier National Park growing? Lysander Spooner University investigates climate claims

by Lysander Spooner University, September 2017


(…) Upon our return to the Hotel after visiting the Glacier, we noticed that our brand-new photos appear to show that the Grinnell Glacier has grown slightly from the 2008 images that are displayed on the Hotel walls. There has been no reporting of this in any newspaper or broadcast that we know of. (In fact, all news coverage reports the precise opposite.) The smaller Gem Glacier—which is visible from the valley miles below—also appears to be slightly larger than it is shown in 2008 pictures on display.

Texas Major Hurricane Intensity Not Related to Gulf Water Temperatures

by Ph.D.  Roy Spencer, August 29th, 2017 in GlobalWarming


As the Houston flood disaster is unfolding, there is considerable debate about whether Hurricane Harvey was influenced by “global warming”. While such an issue matters little to the people of Houston, it does matter for our future infrastructure planning and energy policy.

Let’s review the two basic reasons why the Houston area is experiencing what now looks like a new record amount of total rainfall, at least for a 2-3 day period over an area of tens of thousands of square miles.

Natural Gas Looks Hurricane-Proof, for Now

by Nathaniel Bullard, September 1, 2017 in BloombergView


Since 2005, the U.S. has added more than 120,000 gas wells, mainly in Texas, Pennsylvania, Oklahoma and Colorado. In 2015, there were 555,000 in total.

Those onshore wells have not just made up for declining offshore production, they have handily exceeded it. Offshore gas is now only 4 percent of total U.S. withdrawals. Texas, Pennsylvania, Oklahoma and Colorado are 53 percent of all production.

Water Intrusion in the Chesapeake Bay Region: Is It Caused by Climate-Induced Sea Level Rise?

by Roger H. Bezdek, August 2017 in SciRes


Our findings indicate that the water intrusion problems in the region are due not to “sea level rise”, but primarily to land subsidence due to groundwater depletion and, to a lesser extent, subsidence from glacial isostatic adjustment. We conclude that water intrusion will thus continue even if sea levels decline. These findings are critical because the water intrusion problems in the Chesapeake Bay—and elsewhere—cannot be successfully solved unless their causes are correctly identified and appropriate remedies are devised.

Quantifying the causes of the recent decrease in US CO2 emissions

by Roger Andrews, August 23, 2017 in Energy Matters (blog)


Between 2007 and 2015 total annual US CO2 emissions decreased by 740 million tons (12%). An updated analysis shows that 35% of this decrease was caused by natural gas replacing coal in electricity generation, 30% by lower fuel consumption in the transportation sector, 28% by renewables replacing
