An introduction to global warming impacts

reply to post by dodadoom


As someone else has stated, the Southwest has always been fairly arid, recent La Nina's havent' helped. Add on top of that entirely too many people living there and way too much water diversion by man and you have a recipe for dwindling water. The mighty Colorado River has been reduced to a mere stream with man's damming of it. Yes I agree mankind is responsible for the lack of water in the Southwest but Global warming is not the main cause of that.

You are correct!! I would have to say it is mostly mans inabilty to
develop a sustainable future for himself and his progeny!
Only by extreme manipulation have we been able to get this water
in the first place! Either way, we are digging our own hole.

Or maybe its just a lack of understanding of reality!
After all it IS and HAS BEEN a desert! Good point!
We are bound and determined to conquer mother nature though!
Guess I should have clarified that better. For heavens sake do not take
my word for it without doing your own research. I appologize if
I make an inaccurate statement here. I try to let the reader decide.
I merely said there are indicators these changes are happening!
Thanks for the post!

If anyone dares to keep going, there plenty more.
I know its a problem of unfathomable porportions and
just seems dang overwhelming to even thing about but it seems like
it will become a "big time" problem if we dont do something!
I farm and raise a garden and I can tell ya from first hand experience,
it is getting harder and harder just dealing with the crazy weather!
We do not even agree on this, let alone have the guts to come up with a
plan to wean ourselves off of foreign oil for starters!
Do we really want to live that recklessly?
No fuel, no food! Do we always have to rely on oil in some form? Yes.
Is there a chance with massive efficency changes we could ever use
bio fuels, etc to replace fossil fuels? What about coal? Are we stuck in that hole forever? Since not many seem to give a hoot about the next generations world or the health and sustainability of the planet we live on,
I guess I throw this up just in case we ever do!
Thanks everyone for your posts, stars and flags!

Definately there's more here, for those open enough to even look!
While I realize this will probably not get read, at least I put it out there!
I agree it is far easier to doubt, criticize and disbelieve, than do the research.

Skeptics vigorously criticise any evidence that supports anthropogenic global warming and yet eagerly, even blindly embrace any argument, op-ed piece, blog or study that refutes global warming.

www.skepticalscience.com...

The study uses the MIT Integrated Global Systems Model, a detailed computer simulation of global economic activity and climate processes that has been developed and refined by the Joint Program on the Science and Policy of Global Change since the early 1990s...The new projections, published this month in the American Meteorological Society's Journal of Climate, indicate a median probability of surface warming of 5.2 degrees Celsius by 2100, with a 90% probability range of 3.5 to 7.4 degrees.

Ya' all really need to take a gander at this:

Pollution that we have caused in one century is thus comparable to natural variations that have taken thousands of years.3...The return period and severity of floods, droughts, heatwaves, and storms will worsen.

This doesn't look too good either:

Food is grown in an increasingly smaller area all the time,
due to many factors! Climate change being only one.

Growing crops is getting harder all the time, just due to the crazy weather!

We are using up millions of years of energy in a geologic blink of an eye.

The desert southwest is in a La Nina because the waters of the eastern pacific are colder then normal.
When you get a El Nino condition in the eastern pacific its because the waters get hotter then normal in the eastern pacific.

If global warming is real then the desert southwest will become a lot wetter then they are now.

In fact if the temperatures warm to 5 to 10 degrees hotter then now the desert southwest will become a rain forest because of all the extra rain and flooding they will get.
And the El Nino will become permanent because the eastern pacific will stay hot.

This is scientific fact that the global warmers have conveniently overlooked.

the other fact is when you have a El Nino you have very few hurricanes in the alantic ocean

Oh yeah, "climate change", sorry!
True there are many more variables here than we realize,
methane being released from melting permafrost for instance.
The "global warmers" are very aware of ALL of these changes!
Changing the name of the problem probably isn't going to help much.
We need to learn to adapt and conserve, regardless....
