climate changeA walls and dams will delay major sea level rise for a few centuries and cost 1000 times less

Princeton researchers recommend targeted geoengineering to preserve continental ice sheets. “Geoengineering interventions can be targeted at specific negative consequences of climate change, rather than at the entire planet,” postdoctoral research associate in Atmospheric and Oceanic Sciences Michael Wolovick said. The …

climate changeWas there global warming in the 1880s? Because 25 hurricanes hit the USA in that decade

A total of 293 Atlantic tropical cyclones have produced hurricane-force winds in every state along the Atlantic Ocean and Gulf of Mexico, as well as Pennsylvania. Florida more than any other hurricane. CNN and Jeffrey Sachs are blaming the three …

climate changeModifying natural gas generation to produce lime to reverse climate change

Could we cure climate change? Geoengineering researcher Tim Kruger wants to try. He shares one promising possibility: using natural gas to generate electricity in a way that takes carbon dioxide out of the air. Learn more — both the potential …

climate changeScalable, fast, easy and cheap solutions when we get serious about avoiding climate doomsday

New York Magazine David Wallace-Wells decided to go full doomer with “When the Earth will become uninhabitable”. They got their most read article ever, so they will probably keep it up. The combination of dooms proposed * maximum climate warming …

climate changeCombining geoengineering approaches would keep constant temperatures and overall rainfall

New research from an international team of atmospheric scientists published by Geophysical Research Letters investigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse …

climate changeTests for safe Geoengineering should start now

Technology Review summarizes some of the arguments for and against geoengineering. Alan Robock, a professor of environmental sciences at Rutgers, has published a list of 27 risks and concerns raised by the technology, including its potential to deplete the ozone …

climate“Glassy carbon” electrodes transmit more robust signals to restore motion in people with damaged spinal cords

When people suffer spinal cord injuries and lose mobility in their limbs, it’s a neural signal processing problem. The brain can still send clear electrical impulses and the limbs can still receive them, but the signal gets lost in the …

climateClimate scientists know we cannot prevent 2 degree global change without geoengineering

In 2008 some climate scientiss said that the world had 100 months to enact drastic anti-global warming policies to avoid the environment warming by two degrees celsius compared to pre-industrial times. The 100 months have passed and only modest policies …

climate changeCustomized on demand 3D printed drones produced in less than 24 hours from spec to completion

US Army Research lab has created on demand custom 3d printing of drones. With this concept, once a patrol requires UAV support, Soldiers input all their requirements into mission planning software. The system then knows the optimal configuration for the …

climate changeScale of the threat to US supercarriers from China’s submarines

The Chinese Navy consists of approximately 26 destroyers (21 of which are considered modern), 52 frigates (35 modern), 20 new corvettes, 85 modern missile armed patrol craft, 56 amphibious ships, 42 mine warfare ships (30 modern), more than 50 major …
