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.

Earth Day and the Importance of Green Energy

Blink Charging

According to Forbes , studies have found that solar and wind power is often cheaper than power from fossil fuels, even without financial assistance, and their daily operations undercut even the most cost-effective coal plants. Solar energy is harnessed using photovoltaic cells that capture sunlight and turn it into electricity.

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.

Because of that, soot’s contribution to global warming has been ignored completely in national and international global warming policy legislation, he said. Black carbon is highly efficient at absorbing solar radiation in the atmosphere, just like a black shirt on a sunny day. Dessler et al., 2008] and methane [Schutz et al.,

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. Click to enlarge.

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. There is an obvious link between environmental impacts estimated by life-cycle impact assessments and water quality problems described at the regional scale. Source: “Assessing Biofuels”.

Climate Expert: Don't Call It Geoengineering

Cars That Think

So, we focus significant energy on solar climate intervention, or sunlight reflection. Wanser: We start from the point of view of public safety, which is a concept in international environmental law and environmental law in the United States. We do some work on carbon removal, but that's pretty big space with a lot of investment.
