Study Finds Asian Monsoon Carries Pollution Into the Stratosphere

Green Car Congress

The Asian monsoon circulation provides an effective pathway for pollution from Asia, India, and Indonesia to enter the global stratosphere, according to a new international study led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. NCAR scientist William Randel, the lead author.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet. There were nearly 40 million such flights in 2019.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

Earth Day and the Importance of Green Energy

Blink Charging

In this celebration, we acknowledge the future of green technology is not only healthier for the planet and its residents, but more high-tech than more archaic, higher polluting options. These green tech solutions suitable replacements for pollution-creating solutions. But the sun doesn’t have to be shining to use solar energy.

UC Davis Begins $2.8M Studies on Impacts of Escaped Nitrogen

Green Car Congress

But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters. Nitrogen runoff in bays and coastal areas, where it makes algae numbers spike then crash, drawing oxygen from the water and leading to dead zones—areas that cannot support finfish, shellfish or most other aquatic life.

Study: Urban grime releases NOx when exposed to sunlight

Green Car Congress

When in the air, these compounds may combine with volatile organic compounds to produce ozone, the main component of smog. In a subsequent laboratory comparison, they found that nitrate disappeared from grime 10,000 times faster than from a water-based solution when both were exposed to artificial sunlight. —James Donaldson.

Here’s How We Could Brighten Clouds to Cool the Earth

Cars That Think

Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming. Solar climate intervention is. That's the question the. Marine Cloud Brightening (MCB) Project intends to answer.
