'You have stolen my dreams and my childhood with your empty words,' climate activist Greta Thunberg has told world leaders at the 2019 UN climate action summit in New York. In an emotionally charged speech, she accused them of ignoring the science behind the climate crisis, saying: 'We are in the beginning of a mass extinction and all you can talk about is money and fairy tales of eternal economic growth - how dare you!'
Spot on Miss Thunberg. Her generation will probably end up having to try to sort this mess out aided by a few others who do actually care about the outcome. I hope its not too late for them. I am intrigued how this is gonna pan out and realise I probably will never find out yet wish at least i could see the beginnings of a happy ending. With what I know about how the world operates I have no confidence that it will.
The science says that the carbon dioxide particles in the air reflect radiated heat from Earth's surface back into the Earth's atmosphere (the greenhouse effect). This simple theory ignores the fact that each molecule of carbon dioxide reflects back into space an equal and opposite amount of radiated heat from the sun - the real source of global warming.
The number of carbon dioxide particles in the air is miniscule compared to the number of atoms of oxygen and nitrogen and molecules of water vapour which make up the vast majority of the content of the atmosphere.
The real 'greenhouse gas' component in the air is water vapour. I remember our geography teacher Fred Kemp describing it as like a blanket when you are in bed. He was talking about water vapour in its natural form of clouds.
Of course, that is how it works at night, but in daytime the clouds reflect back into the atmosphere far more heat from the sun than they reflect back to the Earth's surface. But think about how much water vapour is in the atmosphere compared with carbon dioxide.
Plants need carbon dioxide to grow. Cutting back the carbon dioxide in the atmosphere will reduce crop yields at a time when we need to increase yields to feed the growing human population every one of whom exhales a considerable amount of carbon dioxide every year. I can see the answer formulating in some people's minds!

Who else is highlighting the problem though Grist? It's her and her generation's'future so she has a right to moan about it.
I'm no scientist Much but isn't methane a large contributor to global warming and while accepting your arguments about growing more plants don't rotting plants give off more methane emissions?
Whilst not always seeing eye to eye with Mr Kerr, i think he has a valid point about meat production and particularly cattle which contribute a lot to the amount of greenhouse gas we have.
With regard to fossil fuel i believe we need to help developing countries with cleaner technology to help combat emissions.

Does it need highlighting?
It’s been a known issue for decades. Friends of the Earth founded in 1969, Greenpeace in 1971.
It’s a serious problem that’s bigger than Ms Thunbergs Facebook likes tally, to me her antics and scowling face just trivialise the message.
On the subject of empty words we have Harry and Meghan building up their “likes” banging on about global warming but still find it ok to run up a huge carbon footprint by wombling around South Africa
Science can save us, posturing media “personalities” can’t
I don't know how much methane contributes to global warming, I suspect it is not a great deal. Those who argue that we should cull our herds and flocks forget that is their excrement that is used to fertilise the crops we are expected to eat instead. It is one of those cases where you can't have one without the other
No agree Grist a reasonable point about hypocritical Royals. Yes it has been highlighted by the groups you mention but this subject needs to be nagged at us till something is seriously done about it.
Yes methane does have a serious global warming potential, but so does butane and propane, but it doesn't stop us squirting millions of litres into the atmosphere every year via propellants in body sprays, hairsprays, spray paints, and other similar aerosol containers.
