This guy is the biggest idiot in the world.

Attacking the energy industry by demonizing carbon dioxide via the thermodynamic nonsense of the 'greenhouse effect', won't kill off enough people so we have to attack farming, which is the foundation of civilization. Methane and nitrous oxide absorption bands are nowhere near the 8 to 13 micron infra-red window corresponding to black body temperature in the region of 288K, so even by their crap science this is a storm in a teacup. I strongly advise actually reading some of the climate science literature, you will discover just how shaky the foundations of this anti-science folklore is. Nonsense perpetuated through the process of 'peer review' by other knaves and fools.

He says this, at the same time, he is surrounded by plastics and the products of hydrocarbons! The pot calling the kettle black! Have they changed the definition of hypocrisy?

People who think like this guy, come across as hysterical religious fanatics. They're out of their mind and their emotions and beliefs have overridden all common sense and logic. Half the good farmland on Earth is either paved over with strip malls to sell us crap we don't need and nobody wanted before it was advertised to them, or it's growing corn for ethanol production, or it has giant manicured lawns golf courses or sports fields on it. In the USA, something like half the vegetable food grown is thrown away or just left in the field because it isn't pretty enough. There is more than enough land, even in the suburbs, to raise more livestock and grow food, without impeding on open natural environments any more than they already are. ------ Just the energy put into cryptocurrencies, air travel, and new smartphone/computer/internet human surveillance technology, could desalinate water and put pipelines in to grow crops on most of the open desert land. People like this dude, really need to make use of Canada's new euthanasia rules, because they're terminal.

I am so sick of these liars. When will the madness end?

An perfect example that intelligent people can be extremly stupid. He and his comrades could save the climate by stop eating food and drinking water. But he should not force all us others to do the same. After a while when the alarmist have shown us by being a good example, the climate crisis would disappear, and we could live happily ever after.

He can feel free to come to Canada. He can get a MAID shot to help lower the need for farm land.

It's heartening, at least, to read the replies on RTÉ's twitter feed. Most commenters are calling this jackass out.

Anti-humanism disguised as concern for the planet. He's fooling nobody. If there were no climate crisis panic he would be out of a job. Non-validated models based on bogus science which omit regulation processes which have yet to be stimulated will always predict doom sooner or later, even if it is just instability of the integration algorithm.
