"But Global Warming is a HOAX!!!"

[lobosrul5]

Yeah and north of that location it was a high of 54F. And south of there the high was 72.

Yes, one of them because its on the artic coast. Coast is almost always more temperate than inland areas. And there is a cold flow of water up there, that might, slowly be warming. So that could partially go away... I mean the water near the poles is always going to be relatively cold, since they get no sunlight for several months of the year.

The other. A quick glance at the weather map appears to be up in the mountains. I live in a rocky mountain state so I know if I want to beat the heat, I can just go up above 10,000 feet. Theres places in New Mexico that will almost always be colder than Denver CO, or Fargo ND. Problem is, mountains are never going to support the growth of food, not to support billions of people anyways.

I've seen the quip: well if the earth gets 10 degrees hotter we can all just go to Canada or Siberia. Thats not going to work. They will still be brutally cold in the winter anyways. Great now its -30F instead of the usual -45F is not really conducive to large cities in the winter.

My wife's nephew lives in Phoenix, where he works construction. He posted on Facebook yesterday that he picked a good week to take time off. 115F according to his car. 99F record overnight low.

More than 2,000 years ago, the Egyptian and Babylonian and Greek and Persian empires flourished. During this period average Earth temperatures were warmer than today.

More than 2000 years ago the global human population was about 100 million.

Looks to me like they were right around the same as the 1961-1990 average.

We might be 5 degrees C warmer by 2100, thats 9 in Fahrenheit.

Yeah I'm sure if the earth warms up by 5C humanity will make it through... a few percent of us.

Showers.

Now train the cyclists to obey traffic laws.

You know all those youtube clips of dickheads running red lights in CARS and crashing?

Those dickheads ride bicycles too.

They're literally the same people.

I know this because I've been on the boards of a couple of cycling organisations, and found via internal surveys that the cyclists who run red lights etc. behave exactly the same way in their cars.

Also it's extremely rare for an adult cyclist to not also be a driver.

(And the ones that are have often lost their drivers licenses for... you guessed it, traffic violations.)

So the answer is better education for all road users, who'd a thunk it?

 

[Roger Ramjets]

The current Milankovich cycle (interglacial) peaked about 6000 years ago, since then there has been a natural underlying cooling trend of about 0.2C every thousand years. That has been turned into an underlying warming trend of about 0.2C every 15 years by the burning of fossil fuel.

A little bit of increased CO₂ would have been a good thing, but we didn't stop there because it was never part of the plan. The atmosphere is just a convenient sewer for the 40 billion tons of noxious chemicals we dump into it every year.

I'm shocked that a climate change denialist doesn't have a full grasp of the facts.

In the last 2000+ years there has also been significant desertification in Northern Africa and the Middle East which would make it more difficult to maintain such civilisations.

Here is another idea from an email I was sent.
Someone might interpret this?

James Hansen, one of the early voices on climate, says that measures to mitigate the crisis may now, ironically, be contributing to it. He published a working paper this spring suggesting that a reduction in sulfate aerosol particles—or the air pollution associated with burning coal and the global shipping industry—has contributed to warmer temperatures. That’s because these particles cause water droplets to multiply, which brightens clouds and reflects solar heat away from the planet’s surface. Though the paper has not been peer-reviewed, Hansen predicts that environmentally minded policies to reduce these pollutants will likely cause temperatures to rise by 2 degrees Celsius by 2050.

It seems to run counter to his other declarations on the subject:

The world is shifting towards a superheated climate not seen in the past 1m years, prior to human existence, because “we are damned fools” for not acting upon warnings over the climate crisis, according to James Hansen

“There’s a lot more in the pipeline, unless we reduce the greenhouse gas amounts,” Hansen, who is 82, told the Guardian. “These superstorms are a taste of the storms of my grandchildren. We are headed wittingly into the new reality – we knew it was coming.”

Maybe it's a deliberate misunderstanding of something he's published in order to support continued use of fossil fuels ?

And that's really another trick of deniers: Pretend that the claim is that the world will end. The general populace will want to ignore such claims, if they can.

A climate disaster will not end the world, of course. Life on Earth has pulled through much worse. However, human civilization might end, or at least we will suffer very serious and unpleasant push-back.

Even if true it doesn't seem to be helpful in the long run but my mind is not agile enough to figure this.
It seems to say pollute more alongside running carbon through the roof.

Off topic, I’m super curious if there are studies that support this.

There's an easy way to cut through it--cleaner air doesn't escalate. It can have only so much impact, and in the meantime the effect of CO2 reduction will likely counter it well enough if we really do it.

Watch out for people telling you "but we need pollution!". No we don't.

So as the world was getting cooler, the deserts in Africa expanded. Does that mean that as the world gets warmer the deserts will contract?

...James Hansen, one of the early voices on climate, says that measures to mitigate the crisis may now, ironically, be contributing to it...

The reference given for this is not too helpful: an email he was sent, yet it seems to be accurate. Below is a quote from an article on Inside Climate News but it's from Sept. 2021.

James Hansen, a climate scientist who shook Washington when he told Congress 33 years ago that human emissions of greenhouse gases were cooking the planet, is now warning that he expects the rate of global warming to double in the next 20 years. While still warning that it is carbon dioxide and methane that are driving global warming, Hansen said that, in this case...Plunging sulfate aerosol emissions from industrial sources, particularly shipping, could lead global temperatures to surge well beyond the levels prescribed by the Paris Climate Agreement as soon as 2040 “unless appropriate countermeasures are taken,” Hansen wrote, together with Makiko Sato, in a monthly temperature analysis published in August by the Climate Science, Awareness and Solutions center at Columbia University’s Earth Institute. Inside Climate News link

The idea that reducing sulfate aerosol emissions can increase the rate of warming is not new. You can find articles about it in science journals as far back as 2008 or as recent as this year.

You know, if you really wanted to know the answer to such questions - which I don't imagine for a moment you do - you could look them up for yourself.

Huh, maybe warming will be good for North Africa!

"The African Humid Period occurred between 14,800 and 5,500 years ago, and was the last occurrence of a "green Sahara". Conditions in the Sahara during the African Humid Period were dominated by a strong North African Monsoon, resulting in larger annual rainfall totals compared to today's conditions.[17] With the increased rainfall, the vegetation patterns in North Africa were nothing like what we see today. The majority of the Sahara region for instance was characterized by expansive grasslands, also known as steppe. Meanwhile, the Sahel region south of the Sahara was mostly savanna.[18] Today the Sahara region is mostly desert and the Sahel is characterized by savannah grasslands conditions. The African Humid Period was also characterized by a network of vast waterways in the Sahara, consisting of large lakes, rivers, and deltas."

"In the future, the Sahara and Sahelian regions could experience more rainfall than today as a result of climate change. Wetter periods, termed African humid periods, occurred in the past and witnessed a mesic landscape in place of today’s hyperarid and semiarid environment. Such large past changes raise the question of whether the near future might hold in store similar environmental transformations, particularly in view of the growing human-induced climate, land-use, and land-cover changes. In the last decades, geoengineering initiatives (in the form of active re-greening projects of the Sahara and Sahel) have been proposed and could have significant effects on the climate of the region"
