It may be fine for the Earth as a whole. It's not doing anything good for the human population, which depends for its food on an agricultural system that is finely tuned to an atmospheric CO2 concentration of 270ppm.
There are other potential problems, but John Larkin absorbs only denialist propaganda pushed out by the fossil carbon extraction industry, so there is little point in explaining them to him.
Not the news sources I read, but they also include stuff about Donald Trump acting like a petulant twit, which don't seem to show up in the branches of the popular media that John Larkin patronises.
In fact the relationship between rising CO2 level and rising temperature is perfectly obvious, but John Larkin doesn't know enough science to follow t he arguments, and is gullible enough to trust denialist websites on the sub ject.
It may not be bad for the planet but it isn't good for human society, which isn't quite the same thing.
And a few well-heeled people in the fossil carbon extraction industry don't want people to recognise the fact for the very obvious reason that it woul d impact the fossil carbon extraction industry's cash flow, so they spend a lot on climate changer denial propaganda, which gullible people like John Larkin lap up.

But is the extra vegetation the kind we can eat, or the weeds that compete with the plants we eat?
Never heard of him. The denialist propaganda machine has a nasty habit of r ecruiting "scientists" who don't know much about climate science to endorse denialist propaganda. He's a lecturer at Duke University, so "leading phys icist" would be a stretch. Anthony Watts likes him, which does suggest that he's another liar for hire.
In fact it is.
Mann's hockey stick reconstruction was the first of about a dozen now (all based on different proxies for historlical temperatures) which all tell muc h the same story, so Brown is wrong there too.
This has been true for the past five million years, but - geologically spea king - it hasn't happened often in the last 500 million years. Once the con tinents move around a bit more the climate will stop being bistable.
The little ice age was essentially a north Atlantic centred event, and the Maunder minimum doesn't seem to have been relevant.

The Paleocene-Eocene Tharmal Maximum may not have represented any kind of " first order phase transition" since it seems to reflect a massive release o f methane into the atmosphere over a few thousand years, probably from meth ane ice clathrates that got warm enough to release the methane, which produ ced more warming which destablished more clathrates.
This is an obvious misuse of a technical phrase to imply an equally obvious ly non-existent expertise.
We do now know how these transitions work - even if Robert Brown doesn't - and 400ppm CO2 in the atmosphere guarantees that we won't get the kind of p ermament snow fields bulding up at lower latitudes that drive the transitio n from an interglacial to an ice age.
As they are likely to do if the temperate bread-basket gets more tropical o r drought-ridden. The man doesn't know what he is talking about.
A north atlantic phenomenon - ocean currents move around and some parts of the earth get warmer and others colder.
Another north atlantic local effect.

John Larkin might need to recall that not all "grains" are harvestable.

makes the point that only few plants are suitable for cultivation as crops, and the plants that we have fixed on have been vigorously selected for thousands of years to suit our needs a whole better than their ancestors did.
The grains that might do better from a warmer climate are all going to be weeds, not crops.
Whereas climate change already harms the sceptic and the non-sceptic alike.
The serious damage at the moment is largely confined to people who live in the paths of tropical cyclones and typhoons (which have become more intense as the ocean has warmed up), but more warming will produce more victims.
Antifa seems to be an invention of the right-wing press. It's easy enough to buy actor-time and get them to do stuff on camera that fits the expectations of right-wing readers.
The last left-wing demonstration that I took part in - against the the Vietnam war, so quite a while ago - had bunch of left-wing monitors watching out for hot-headed kids who might do things that wouldn't look good if reporters managed to photograph them.

From what I can see Antifa is real. They have their own organization and a ctivities although they are not terribly active. It's funny that while ver y real, the extreme right wing groups seem to have little actual support. Many of the protesters who joined them in Charlottesville were just doing i t as a lark. They had never been in any right wing action before.
Both groups are reprehensible.

like you have collected some data when you have none. CO2 started increas ing with the industrial revolution. The rise in CO2 since then maps pretty well to the rise in temperature. That alone is more evidence than crying "rain forest".
self interest is more credible. Climate 'scientists' can be on the front bu rner or the back - naturally they make more money at the front of public aw areness.

Actually, they don't.
The self-interest that drives climate change denial is much more obvious - a small but remarkably wealthly bunch of people make money out of digging u p fossil carbon and selling it as fuel.
Any effective action to slow down climate change is going to reduce the vol ume of fossil carbon they can sell, and diminish their cash flow.
They've got quite enough money to buy loads of denialist propaganda from th e organisations that were orginally set up to tell that smoking didn't seri ously damage your health.

NT is the kind of half-wit that thinks that the amount of extra money an ac ademic can make by getting newspaper column inches is going to be big enoug h to persuade them to risk their academic careers by publishing nonsense.
There's a lot more money to be had by publishing nonsense that denies anthr opogenic climate change - which does wreck your academic crediblity, but if you didn't have much to start with this isn't quite so important.
Cursitor Doom recently posted a pile of steaming twaddle from a lecturer in physics at Duke Univeristy - a Roger Brown - which is a representative sam ple.
Cursitor Doom told us that he was a "leading physicist" - which would perha ps be an abbreviated form of "leading people up the garden path physicist" or perhaps merely the truncated version of "misleading physicist".
Google suggests that the only public attention that he has got has been fro m the denialist propaganda machine.
Happily Australia has a lower population density than even the US, so my brain was less damaged than John Larkin's (at least when I was growing up in rural Tasmania. NT would have been even worse off than John Larkin.
Now that gasoline is unleaded there are fewer of them.
But there's also no shortage of ill-informed geriatic cases who suffer from exactly the same delusion, and NT is a remarkably ill-informed sample of the breed.
He seems to be as vain as John Larkin, so he really isn't likely to admit this to himself or anybody else.

The sentence was too long for NT's limited processing skills to handle. Pity about that. If I were writing for NT's benefit I'd keep the sentences shorter and simpler, but who'd waste the time on tyring to inform him?

Roughly my reading of the situation, but I suspect that here it is the lead ing role of right-wing money, rather than the leading role of the communist party, which is falsifying the label they've chosen to present to the worl d.
Cursitor Doom sees stuff on the media he choses to pay attention to, which are all obviously designed to give right-wing nitwits a picture of the worl d which fits their prejudices.
And of course the US is rapidly becoming a 3rd world shit-hole country for everybody but the top 1% of the income distribution. Check out their health

Reagan started the process, and Trump is prosecuting it with enthusiasm, if not all that effectively.
Antifa showed up at Charlottesville like they were going to open up with a flamethrower on those polo-shirt wearing tiki-torch carrying bumpkins marching around under the Nazi flag and vaporize like 500 of 'em and then they didn't do that. so not terribly effective at the whole "anti-fascist" game relatively speaking.
