My big bugbear on all the climate debate is how certain pieces of information are totally ignored(very UN scientific) and the positives of global warming are never mentioned.
Fluctuations in solar radiation of just 1 % will alter the earth's climate. We are not at present able to measure this .At this stage, there is nothing we can do about this.
The climate doomsayers say Venus is an example of runaway greenhouse. hello, Venus has a particularly thick atmosphere and is much closer to the sun, hence considerably higher solar radiation input over billions of years.
What is the major greenhouse gas?............................... ..........yes, it is water vapour.CO2 is a very minor contributor.
Our planet has had much higher CO2 levels in the past, and no runaway greenhouse.In fact it was a very verdant place, the carboniferous era. Perhaps us humans are on this planet to recycle that carbon buried under the ground as coal to get the CO2 back for the plants.
Many plants use MOST of their water in the transpiration process to extract CO2 from the atmosphere. CO2 is a limiting factor in plant growth. This means higher yields in more arid conditions. Is the general public ever allowed to hear this?
Fossil records, ice core analysis etc show the planet goes through its ups and downs in temperature- before humans were on this planet. How arrogant are we as a species that think we have such control of the climate.More harm is done by our population spread induced habitat destruction than the CO2 release.Perhaps we need to cull the human species, perhaps by 90% to be CO2 neutral?
In the distant past, fossil history has shown many instances of climatic change. A species must adapt or become extinct. As a species, we must adapt or become extinct in a sea of our own foolishness.
The whole climate debate is stewing in its own rhetoric and almost religous fervor.

As for astronomy, more clouds = less photonic input.
