Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Green Car Congress

Decadal warming rates arising from (i) greenhouse gases and aerosols alone (black); (ii) that obtained including the stratospheric water decline after 2000 (red); and (iii) including both the stratospheric water vapor decline after 2000 and the increase in the 1980s and 1990s (cyan). Stratospheric water vapor and radiative processes.

The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Depletion of fresh water reserves [m 3 ]. The top sample above shows climate change impact; the subsequent chart shows human toxicity. Sample results from Carculator.

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

To analyze this, Wang headed to Switzerland as a member of the CLOUD collaboration to test his experiment at the European Council for Research Nuclear (CERN). All of the scientific uncertainty around climate change relates to clouds in one way or another, said Wang’s advisor and co-author Neil Donahue, professor in chemistry.

A Roomba for Rivers

Cars That Think

Humankind is enamored with water. The machine, which can run autonomously or at the direction of a remote operator, goes around collecting the junk and gunk (like plastic bottles, oil spills, and algae) that float on the water, as well as detritus located up to 10 meters below the surface. Roomba for Rivers.

IEEE Discusses 6 Simple Solutions to Climate Change at COP27

Cars That Think

Simple, effective solutions that can help lessen the impact of climate change already exist. Rahman, a power expert and professor of electrical and computer engineering at Virginia Tech , is the former chair of the IEEE ad hoc committee on climate change. France sells energy to Italy, Spain, and Switzerland,” Rahman said.

Study Finds Unexpected Decadal Decline in Global Evapotranspiration, Links It to Moisture Limitation in Southern Hemisphere

Green Car Congress

Most climate models have suggested that evapotranspiration, which is the movement of water from the land to the atmosphere, would increase with global warming because of increased evaporation of water from the ocean and more precipitation overall. Data indeed show that some areas are wetter than they used to be. Jung et al.
