Study finds climate impact of hydropower varies widely

Green Car Congress

earlier post ), a new study by a team at Environmental Defense Fund finds that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels. They also estimated emissions caused by flooding the reservoir.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,

Study Finds Indian Ocean Sea-Level Rise Threatens Coastal Areas; Climate Change Partly Responsible

Green Car Congress

finds that the sea-level rise is at least partly a result of climate change. The rise—which may aggravate monsoon flooding in Bangladesh and India—could have future impacts on both regional and global climate. In addition, the team used a wind-driven, linear ocean model for the study. The Indo-Pacific warm pool.

BloombergNEF: clean energy investment in developing nations slumps as financing in China slows; coal burn surges to record high

Green Car Congress

New investment in wind, solar, and other clean energy projects in developing nations dropped sharply in 2018, largely due to a slowdown in China. This is due to wind and solar projects generating only when natural resources are available while oil, coal, and gas plants can potentially produce around the clock.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

The result implies that globally, cloud changes caused by particles from all forms of industrial pollution block 1 Watt of solar energy per square meter of Earth’s surface, masking almost a third of the present-day warming from greenhouse gases. The results also have implications for one possible mechanism of deliberate climate intervention.
