Since Earth acquired an atmosphere, climate has never been a constant. It is, by default, a variable. Humankind cannot stop it; our species must instead adapt to it, as we have throughout our existence.
Over the last 20,000 years, global sea level has risen by 400ft. Just 5 - 8 inches of that has occurred since 1900, which encompasses the vast majority of anthropogenic influence on the total.
20,000 years ago, (what we now call) England was connected to continental Europe from Norfolk to Cornwall. The last vestiges of the landbridge became submerged around 8,200 years ago.
7,000 years ago, Mega Lake Chad was believed to be the largest freshwater lake on the planet at 131,400 square miles and upto 520 feet in depth. Today we call this area "The Sahara Desert." Did humankind cause this change?
Just note how short these timescales are. We're not talking anything close to the 65 million years since the great dinosaur extinction. 7,000 years is around 150 human lifespans, given an average age of 47 years.
Whilst those who are fully committed to the secular-religious cult which now promotes so-called "climate emergency" will never admit it, human contribution to climate variation is extremely marginal. Whatever we do, how ever much we spend, humankind CANNOT meaningfully influence the natural and enduring processes of climate. We are King Knut, shouting at the tide to turn back. What we can do is adapt to those new conditions presented by natural change. And don't forget, not all consequences of climate change are bad - there are advantages and disadvantages - though some would have us forbidden to utter that truth. I strongly endorse the proposals of Bjorn Lomborg to mitigate (not prevent - we can't do that) the effects of climate change in a practical and constructive way. We should be motivated to tackle pollution, but not through fantasy and threat.
I have long advocated for leading figures in the aviation industry (and others) to call out the absolute fear-porn climate BS promoted by extremist interests. Why are we allowing our industries and way of life be persecuted by climate zealots who cherry-pick favourable data and ostracise expert academics who speak the truth? Farmers on the continent are finally showing the red card to their crackpot politicians. Good on them. The sooner the airline industry has the b***s to speak afew home truths as well, the better. Surely we have some well-respected execs who dare speak up for common sense?
Stand up for the GOOD that international travel brings! Support the environment through scientific advance, not luddite bans. The movement cap currently enforced at DUB and the recently-attempted version at AMS are lunacy. The zealots backing these will never be satisfied ... they always want more. Flight-shaming and random flying bans will proliferate if not opposed. We in the industry MUST stand up for common sense.
Sorry that this post is less than Manchester-specific, but this airport is in the firing line as much as any other.
