Why does the rising of high clouds due to climate change impart positive radiative feedback on radiative forcing?

As seen in the figure below. The larger the temperature difference between surface and cloud, the more positive the radiative forcing is from the cloud. So as the cloud moves up, it supposedly ...

Is global warming occuring only because of humans? [duplicate]

I learned that human activities produce gases that deplete the ozone layer, and create the greenhouse layer, which increases the world's temperature. (And seems real , now in Thailand it's 35 degree ...

How much will sea level rise if all the polar ice melts?

There are many movies about global warming, which say that melting of all polar ice would cause the whole world to suffer a huge flood. According my research (teachers, TV, Internet) people hold one ...

Is it possible to forecast ocean salinity 100 years into the future?

Paleosalinity is measured by chloricity of pore fluids (Adkins 2002). Current data are provided by the CORA dataset. In addition to answers to the main question, there are a few more points I'd like ...

Will tropical cyclones form and be sustained in areas they previously were not due to global climate change?

With global climate change, is it possible that tropical cyclones (as seen in the Atlantic basin for example) are going to form and be sustained in regions where they previously did not, for example ...

How will climate change affect the entropy budget of the atmosphere?

The entropy per unit mass of moist air can be defined as $$s=(1-q_t)(C_{pd} \ln{T}-R_d\ln{p_d})+q_tC_l\ln{T} + \frac{q_vL_v}{T}-q_vR_v\ln{\mathcal{H}}$$ And in statistical equilibrium, the entropy ...
