We’re No. 1: Global warming has surpassed global cycle – Haaretz

In the last 150 years, since the industrial revolution began, anthropogenic heating has increased the global mean temperature by more than 1 degree Celsius. That increase has wiped out the natural cooling trend that began 6,500 years ago, in which…

Ex-Alarmist Disputes So-Called ‘Climate Crisis’ In New Book

Environmentalist Michael Shellenberger got off to a rocky start with his book launch when Forbes deactivated his column apologizing for the “climate scare,” but the magazine may have done him a favor. The backlash prompted a host of feisty contrarian…

Sen. Cruz Signs Pledge To Keep U.S. Dominant Natural Gas Producer

Sen. Ted Cruz is among 141 political leaders in a pledge to keep the United States’ energy industry dominant amid the coronavirus pandemic and the consequential economic downturn. The Texas Republican, as well as seven additional senators, three governors, and…

Global threats: How lessons from COVID-19 can prevent environmental meltdown

(Princeton University, Woodrow Wilson School of Public and International Affairs) COVID-19, climate emergencies, and mass extinction all share striking similarities, especially with regard to their ‘lagged impacts.’ In each, early intervention can prevent further damage.

Learn from the pandemic to prevent environmental catastrophe, scientists argue

(University of Cambridge) COVID-19 is comparable to climate and extinction emergencies. All share features such as lagged impacts, feedback loops, and complex dynamics. Delayed action in the pandemic cost lives and economic growth, just as it will with environmental crises – but on a scale ‘too grave to contemplate’, say scientists from UK and US.

A shake-up in cell culturing: Flame sterilization may affect the culture

(University of Tsukuba) Researchers from the University of Tsukuba have found that flame-sterilizing shake-flasks, to avoid introducing microbial contaminants, considerably increases the carbon dioxide concentration in the flasks. This enhanced carbon dioxide concentration affects the growth of some microbial species, which may affect the quantity of vaccines or other valuable substances produced by the microbes.

Buzzing to rebuild broken bone

Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward, engineers report. Although minor bone breaks usually heal on their own, large fractures with shattered or missing chunks of bone are more difficult to repair. A biocompatible, dissolving polymer device can mimic the body’s natural electrical field and help the cells regenerate.

Major new paleoclimatology study shows global warming has upended 6500 years of cooling – EurekAlert

Geologists identify deep-earth structures that may signal hidden metal lodes

(Earth Institute at Columbia University) In a new study, scientists have discovered previously unrecognized structural lines 100 miles or more down in the earth that appear to signal the locations of giant deposits of copper, lead, zinc and other vital metals lying close enough to the surface to be mined, but too far down to be found using current exploration methods.

Beavers gnawing away at the permafrost

Alaska’s beavers are profiting from climate change, and spreading rapidly. In just a few years’ time, they have not only expanded into many tundra regions where they’d never been seen before; they’re also building more and more dams in their new homes, creating a host of new water bodies.
