Yes, water in the atmosphere is the biggest player in the greenhouse gas game. However, it is very volatile and varies strongly. CO2 is a more "consistent" player in that game, albeit its effect being smaller than water vapor, its effect still being significant. Of course changing average temperatures through CO2 will have an effect on water in the atmosphere.


Nope. There is no such thing as a 'greenhouse' gas. You are again ignoring science. See the 1st and 2nd laws of thermodynamics and the Stefan-Boltzmann law.

Define 'climate change'. A meaningless buzzword is not a scenario at all.

So you now openly deny the 1st and 2nd laws of thermodynamics and the Stefan-Boltzmann law.

No, you can't just discard theories of science, dude.

Water vapor does indeed absorb infrared light just like CO2 does. There is a lot more of it too. However, absorption of surface infrared light does not warm the Earth.

It actually cools the surface.


When are you going to give up passing out stupidities? Not only is there about a world wide average humidity of about 2% all the time but it absorbs almost entirely across the Infrared spectrum whereas CO2 only absorbs in three very narrow bands which are at the very bottom of the Sun's emissions and at the very top of the Earth's emission and hence there is very little energy there.

In case you are unaware of it - the way in which heat is absorbed and moved through either radiation or conduction cools the surfaces from which the heat is extracted.

Is there anything at all that you understand?

Inversion fallacy. I should ask you that question.

No, it does not. Not even close.

Which are different than the narrow bands for water.
Wake wrote:

WRONG. The Sun emits light all the way down into the radio bands.
Wake wrote:

WRONG. Earth emits many different frequencies of infrared light.

Most of the Sun's energy is infrared, Wake.

Try English next time. Absorption is does not cool anything, Wake.

I don't think molecules work like heat sponges. Heat spreads out, dissipates. Where stuff can't move around, everything would eventually reach the same temperature. The gasses can move, and heat rises, surface heat, would be dissipated upward. The only warming could come from an energy source, like the Sun. For water to evaporate, it needs some heat. More heat, more vapor, the estimate is between 0% to 4%, but suspect it can go higher, if there is sufficient heat. Think around 4% is where it's blocking out much of the solar source. How come H2O isn't the bad guy here, if it's wide spectrum, and does the same as man-made CO2, and can be a thousand times more of it. CO2 would be only left with the scraps, of what H2O didn't grab up. And this isn't a science fiction story...

* most of production growth is due to technological advances
* Ukraine is in economical transition, so there is sharp increase in production, while earlier for quite long period production was nearly stalled
* Russia seems to partially transition too to more modern (at least economical) standards, so there is expected increase too
* for small global warming, crop area (corn) increases significantly, but the more north the less light received and lines of constant latitude are shorter so there is smaller area for each shift of agriculture toward poles (further north than half of Canada or 65 deg North you will have significantly smaller land area) of each new shift so further warming is expected to give rapidly diminishing increases of production
* further global warming will soon start to impair significantly any crop production in equatorial zone
* global warming is correlated with increased evaporation and increase of water vapor content in atmosphere (it is btw one of main amplifying mechanism of global warming), increased vapor is correlated with higher altitude of tropopause, higher altitude of tropopause causes more frequent and more severe hailstorms, which are devastating for agriculture
* further global warming starting from current level may cause high increase of frequency and severity of droughts, floods and heatwaves which also are devastating for food production

It seems that we are already at level (or even have passed) when any further global warming will lead to more negative effects for food production than positive, even if some small warming starting from preindustrial level was mostly positive. Looking at Brazil and how quickly they cut out forests to produce more food due to world production not meeting world demand, it seems that we already reached that level few years ago...

Also I wouldn't ignore increased risk (hailstorms, droughts, floods and heatwaves) when it comes to food production. It is different type of risk than economic risk where is possible printing money to bailout economy or energetic risk were is possible to quickly blow out whole mountain to supply additional coal - there is no any emergency solution in case if food production fails in multiple regions of the world at the same time (it isn't possible to quickly print food or dig it from earth if there is shortage).

Good news! The Global Warming problem has been solved and all negative effects that were going to happen have thankfully been averted.

Now we can fix our attention onto other issues. Personally, I'm going to celebrate with some rum&coke first.

Congratulations everyone!

Correction: further from equator than 70 deg (both hemispheres) there is smaller area for each shift of agriculture toward poles.

Currently agriculture seems to end in Canada somewhere at 60 deg North (on south hemisphere there is no land at this latitude), so without correction for atmosphere:
* at 60 deg latitude land receives 50% of sunlight per area due to angle
* at 70 deg latitude land receives 34% of sunlight per area due to angle
with correction for atmospheric absorbtion (aerosols, clouds etc.) it will be even less toward poles since Sun is always low above horizon and light has much longer path through atmosphere before it reaches surface

Is it possible to have a drought and flooding at the same time?

CO2 really is a magic molecule... It warms the earth, but it also makes plants grow faster, strong, healthier.

What hail? It thought CO2 was melting all ice on the planet. Would the hail melt, long before it got close enough to our precious food plants?

Everything depends on plants, one way or another, for food. I wouldn't have ribeye steak, if cattle didn't graze. What do Canadians eat, if they aren't growing crops? Perhaps you aren't familiar with the far north... The grows some of the largest animals up up that way, which don't seem to have much trouble finding food. They main problem, is people, who hate them, save all year, just travel up there and murder a couple. Mostly to take selfie with the corpse.

I really don't get all the hype and urgency. Migration happens, because things change. It's been that way, well likely before man stood and walk on his hind legs. If the land your standing on, doesn't provide what you need to survive, you move on, until you find what you need. The 'tipping point', 'point of no return', is just ten years away. Well, unless they reset the countdown clock again, for the third or fourth time. But the apocalyptic prophecies aren't expected to be fulfilled, for hundreds of years from now, or when ever they stop resetting the clock. Most birds, animals, and other critters, do their seasonal migrations in a month or two. We've got several hundred years to find places that better suit our wants and needs. If you just can't stand the though of giving up you beachfront property, learn swim. If you farm, and one type of crop isn't doing so well, plant something else.
