How bad could climate become?

[Whereisup]

There is no way to predict for sure, but consider the analogy of heating a pot of water.

At first, there is only a small gentle movement of the water in the pot. However, as the water is heated, the water moves faster and faster.

Similarly, as the atmosphere heats up, air masses will on average move faster. That will produce greater shifts between cold and hot, wet and dry. There will be more flooding, more tornadoes, more hurricanes.

The expense of all that damage caused by the weather will be much greater than the cost would be if we quickly shifted to mostly wind and solar power.

How bad?

Let's see. The Sahara Desert used to be a wooded savannah. The Ice Age killed most of life on earth. The Medieval Warm Period got pretty warm, it enabled exploration to expand. Agriculture started on previously ice bound areas.

None of that had anything to do with polluting the atmosphere and activities of mankind. So, whatever the climate does, it has nothing to do with us.

Dang.....never thought that we might see somebody more naïve than Chris on this forum, but I guess anything is possible.


s0n.....head back over to People.com and blog over there.

Imagine temperature like death valley with 60f dew points over a large part of the southern United states and southern Europe for weeks during the summer.

That's 8c of global warming. Entire parts of the world would become unlivable.

What i get from Obama and his ilk is that the US is the cause of all this and we need to
fix it.

All that extra energy is frightening you? PLEASE don't move South of the Mason Dixon line.. The extra energy in Pensacola is almost unsurvivable.. It's complete climatic demolition in Nicaragua. Weather systems there move SOOOO fast --- you don't even hear death coming..

Imagine 115f with 65f dewpoints in New York?
Imagine 130f+ in Dallas with 55f dewpoints
Imagine Italy, Spain and a larger part of the globe NOT just death valley being a living hell. That's 8-12c of warming.

That's EXACTLY how much we warmed up since 14,000 years ago.

Imagine a Chicago 1995 heat wave occurring every year? But with temperatures of 110f!

2-3 thousand people dying.

That's 8+ more of warming by 2100.

Got a date on that?

This has been one cool July in Chattanooga | timesfreepress.com


Chattanooga is on track to finish its coolest July in 34 years.

That's not just a NEW daily high.. That's an entire MONTH in the MIDDLE of summer..

Stop scaring the kiddies.. Their minds have already been bent by public school pseudo-science..

Earth Could Become Too Hot for Humans

Earth's current warming trend could bring deadly heat for humans.

A new study that looked at reasonable worst-case scenarios for global warming found that if greenhouse gases continue to be emitted at their current rate, temperatures could become deadly in coming centuries.


"We found that a warming of 12 degrees Fahrenheit (roughly 7 degrees Celsius) would cause some areas of the world to surpass the wet-bulb temperature limit, and a 21-degree warming would put half of the world's population in an uninhabitable environment," Huber said.

"Whole countries would intermittently be subject to severe heat stress requiring large-scale adaptation efforts," Huber added. "One can imagine that such efforts, for example the wider adoption of air conditioning, would cause the power requirements to soar, and the affordability of such approaches is in question for much of the Third World that would bear the brunt of these impacts. In addition, the livestock on which we rely would still be exposed, and it would make any form of outside work hazardous."

The results of the study are detailed in the May 6 issue of the journal Proceedings of the National Academy of Sciences.

That just proves how big 6-8c of climate charge is.

An adaptability limit to climate change due to heat stress


Recent studies have highlighted the possibility of large global
warmings in the absence of strong mitigation measures, for
example the possibility of over 7 °C of warming this century alone
(1). Warming will not stop in 2100 if emissions continue. Each
doubling of carbon dioxide is expected to produce 1.9–4.5 °C
of warming at equilibrium, but this is poorly constrained on
the high side (2, 3) and according to one new estimate has a
5% chance of exceeding 7.1 °C per doubling (4).

Because combustion of all available fossil fuels could produce 2.75 doublings
of CO2 by 2300 (5), even a 4.5 °C sensitivity could eventually produce
12 °C of warming

Thus while central estimates of business-asusual
warming by 2100 are 3–4 °C, eventual warmings of 10 °C
are quite feasible and even 20 °C is theoretically possible (9).

Pure catastrophy pandering and hype.. NO ONE and I mean NO ONE is now supporting ANYTHING approaching that sci-fi fantasy...

We are currently on track for a 1.6degC result for current doubling.. From 280 to 560ppm. Might get there BEFORE 2100.. The theoretical warming from CO2 ALONE is 1.1degC.

((And that 1.6degC is DROPPING every year that the temp. increase has stalled))

All of this fragile earth and atmos crap is speculation. 5% chance???

Quit scaring the grade schoolers..

Don't worry.. I think it's still under factory warranty..

There is so much to learn about the PRIMARY driver of the Earth's climate. We need another 20 yrs in space just to understand how much of a "fixer-upper" neighborhood we bought into...

 

[Katzndogz]

It isn't as warm now as it was in the Medieval Warm Period.

Here is what you need to understand.

The earth is living. The sun is living. There will be periods of warmth and periods of cooling. It is entirely possible that we could be boilled alive in a supernova. The sun could dim and we would be buried in feet of ice. A large asteroid could smash earth to bits and turn our orbit into another asteroid belt. It's just not probable. There is nothing we could do about any of it.

Wow, yet another socko. To your point the weather has been worse in the not too distant past and the worst possible thing that could happen would be another Little Ice Age, which would see food stocks vastly diminished, war and famine would follow in its wake.

No thanks. Give me a couple of degrees of warmth any day of the week. And for the record, it is COLD fronts that do the damage...not warm fronts. Take a look at the equatorial weather where it is constant global warming if you would like to see what a warm paradise is like.

And EVEN more would become livable. Look at a globe sometime there Matthew.
