The sun is the only reason we can exist, the earth would not be even there as an accretion of materials, without a central gravitaional force.
Simply, we could not live without the sun, but it certainly is also reponsible for all kind of climate changes through the ages.
There are certainly also asteroids posing a threat to climate changes and real destruction, but in normal times, apart from direct radiation, the electric-magnetic field is being influenced by the sun, and thus temperature and the weather.
All the hype of this rising CO2 levels are not the cause, but the result of a global warming, which has happened before numerous times. We can probe CO and temperature levels going back much longer that 1500 years, but astonishingly in our climate models, most scientists only look at those last 1500, and we even disregard short warm-times, and colder times, only existing for 50 year-intervals within those 1500 years.
Apart from political agendas and the urge for feeling bad, mankind has not had much influence on global warming.
Dangerous litter plastic emmollient/plasticizer and poisoneous waste is another thing, but it only promotes cancer and contamination, not the climate.
But they are "working", on the latter.
