The reason the Holocene began about 12000 years ago was because that was when Northern Hemisphere summers were hot but short. Those hot summers started a melting process. Right now, July is when the Earth is furthest from the Sun. This makes Northern Hemisphere summers long but mild. That is one of the key conditions that enables a glaciation to start. In ...

I am doing some calculations on this question myself. The atmospheric lapse rate is about 6.5K/1.000m. The adiabatic lapse rate is 9.8K/1.000 and the dry lapse rate of the naturally unstable atmosphere of Earth should even be 10.8K. So arguably the constant transport of latent heat by vapor from the surface into the atmosphere is reducing the lapse rate by ...

No! There was never a claim that temperatures rose after 9/11. The suggestion was only about an increased temperature spread, which is definitely true. Not that it could be told from post 9/11 observation for sure, but there is more research on the subject which shows contrails reduce the daily temperature spread. As to be expected anyway. However the ...
