The overall impact of clouds on global climate depends on factors such as cloud type, altitude, thickness, and the amount of water or ice they contain. Thin, high-altitude cirrus clouds tend to have a net warming effect, since they allow incoming solar radiation to pass through while trapping heat radiating from the Earth's surface.
If climate change causes low-level cloud cover to become more widespread, then these clouds will increase planetary albedo and contribute to cooling, making the overall cloud feedback negative (one that slows down the warming). But if clouds become higher and thinner due to climate change, then the net cloud feedback will be positive and ...
Scientists subsequently tested the hypothesis. Some concluded that there was no evidence supporting the hypothesis. [3] Others found evidence suggesting that increased sea surface temperature (SST) in the tropics did indeed reduce cirrus clouds but found that the effect was nonetheless a positive climate feedback rather than the negative feedback that Lindzen had hypothesized.

In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes.

This is a list of climate change initiatives of international, national, regional, and local political initiatives to take action on climate change (global warming). A Climate Action Plan (CAP) is a set of strategies intended to guide efforts for climate change mitigation. [1]
Cloud seeding can be done by ground generators (left) or planes. Cloud seeding is a common technique to enhance precipitation. Cloud seeding entails spraying small particles, such as silver iodide, onto clouds to attempt to affect their development, usually with the goal of increasing precipitation. Cloud seeding only works to the extent that ...
