NO, GLOBAL WARMING WON’T KILL YOU
Are you terrified by claims that global warming is an “existential threat”? That there will be a “great winnowing” and “mass deaths”? That we face “the collapse of our civilisations”?
Don’t believe those scares.
You are told to believe “the science”. Well, here is some science you should believe – solid scientific facts that tell you that global warming is not as scary as you’ve been told.
Be calm. You are not in danger.

"How Dare You" add facts to the debate.
Have you no shame?
Thank goodness reason prevails
Most if not all, are not clear-cut. As to be expected.
Good on you Andrew. But you have missed the fact that CO2 emits heat when irradiated with IR radiation. Now this is a fundamental fact that is due to its never changing molecular structure. It trumps all the other facts.

We are unable to scientifically calculate the extent of the previous periods of Ice Ages and Global warming of our Earth After all if coal is derived from vegetation ,please tell me how we have coal seams many kilometres below ground level.?? Yes the Earth is in a climate warming period ,and we have absolutely no way of stopping it. Just hang on and enjoy our wonderful world as it is.
Reply to 'Unknown' :- Another fundamental fact regarding CO2 in the atmosphere is that even if it's volume has doubled, the AMOUNT is still infinitesimal! Of the greenhouse gases WATER in all its cyclical forms,properties, and amount, is the greatest regulator.
@Unknown
That is true, but it doesn't change the overall heat of the atmosphere at all. A Co2 molecule absorbs an infra-red photon, and then re-emits it later. Whether the photon was incoming or outgoing, the energy involved remains the same.
@Unknown
Unknown is correct that CO2 absorbs IR and warms, but so does the much more important water vapour.
However, when any gas is warmed - it rises. In the case of water vapour - this is visible as clouds when the water vapour expands as it rises with falling pressure and condenses as it cools.
In the case of CO2 - it simply continues to rise and fall in temperature with expansion.
In each case an equivalent volume of colder air from the upper atmosphere descends to re-establish the previous equilibrium.
Warmer gases rise to radiate heat to the infinite sink of outer space which is at ~ 5ยบ K.
So - yes while there is no debate CO2 absorbs IR - that does not mean it heats the atmosphere.
Very helpful. Thank you so much.
