What do you think about Global Warming?

Question

Do you get scared?

Answer 1

Global warming as a stand alone theory was first modeled by Southampton University back in 1980. Whilst lots of the warming the model suggested worked there were too many areas that were cooling.

Most scientists now use the term "Climate Change" as this far more accurately covers what is going on.

The same amount of rain is falling but just in different places causing floods in one area and droughts in another.
The thermohaline ocean current has slowed and changed, The Southern Hemisphere westerly winds have moved southward in the last 30 years
Much of the continental United States has actually grown slightly colder. The trend toward cooler temperatures in the central and eastern United States is due to warmer ocean temperatures.
The main cause of the melting of ice sheets has been a strengthening in warm westerly winds blowing on to the peninsula. This melts surface ice which seeps through cracks thereby forming blocks. There is natural water under the ice which acts as a lubricant when the block is released to allow it to slide away.

But whilst one area warms another cools and this has been shown to have happened many times in Earths history.

Whilst "Global Warming" is a term that can be used within climate change it is entirely misleading and counterproductive to try and use it as a stand alone term.

It is a rallying cry for ecowarriors with closed minds bent on proving man is destroying the planet whilst they refuse to debate the truth. No wonder the United States politicians refuse to believe it! And the US remains the highest polluter with 5% of the world population contributing 25% of the pollution! It is probably poetic justice that the US has suffered the most from weather changes.

We really would be better off if we could dump the term completely and refer instead to the warming effects associated with Climate Change.

Scared? Only that the ecowarriors will succeed and be silly enough to impose changes that will damage the Earth instead of saving it!

Answer 2

I definitely do not get scared over Global Warming. Global Warming is the pseudo-science pet o fthe decade for Al Gore and company. There is absolutely no evidence that man has done anything to contribute to Global Warmining. The amount of warming around the world is in fact miniscule and is more than likely a very normal cyclic event for the earth. We have only kept track of temperatures for approximately 400 years. The earth is 4.2 plus billion years old. We have no clue about its cycles. Everyone needs to relax. If in 400 years we see a change of less than 1/3 degree farenheit in the global temperature I think we are all going to be just fine for quite sometime.

Answer 3

This is what I think

The potential planetary warming from a doubling of atmospheric carbon dioxide from pre-Industrial Revolution levels of ~280ppmv to 560ppmv (possible some time later this century - perhaps) is generally estimated at less than 1 °C.


The total warming since measurements have been attempted is thought to be about 0.6 degrees Centigrade.

At least half of the estimated temperature increment occurred before 1950, prior to significant change in atmospheric carbon dioxide levels.

There is no linear relationship between atmospheric carbon dioxide change and global mean temperature or global mean temperature trend -- global mean temperature has both risen and fallen during the period atmospheric carbon dioxide has been rising.


Other anthropogenic effects are vastly more important, at least on local and regional scales.

Fixation on atmospheric carbon dioxide is a distraction from these more important anthropogenic effects.

Despite attempts to label atmospheric carbon dioxide a "pollutant" it is, in fact, an essential trace gas, the increasing abundance of which is a bonus for the bulk of the biosphere.

There is no reason to believe that slightly lower temperatures are somehow preferable to slightly higher temperatures - there is no known "optimal" nor any known means of knowingly and predictably adjusting some sort of planetary thermostat.

Fluctuations in atmospheric carbon dioxide are of little relevance in the short to medium term (although should levels fall too low it could prove problematic in the longer-term).

Activists and zealots constantly shrilling over atmospheric carbon dioxide are misdirecting attention and effort from real and potentially addressable local, regional and planetary problems.


Does Al Gore really believe in catastrophic global warming? Since Al Gore was offered the opportunity (in person) to facilitate serious debate on the underlying science of global climate change, 11 months, 1 day, 7 hours, 29 minutes, and 11 seconds have elapsed.

Despite milking lucrative speaking engagements and book deals with his global warming shtick he declines any such debate.

Answer 4

I sure do! We're already seeing marine extinctions, more severe weather patterns, we're losing glaciars, atmospheric carbon dioxide is rising at an unprecedented rate, and disease vectors are shifting. A lot of animals are changing migratory paths and shifting north.
Also, sea level is rising.
And it's just going to get hotter

For all those who say it has been this hot in the past, geologically speaking, they are telling the truth. However, the rate of increase is unprecedented and also, those past conditions? You wouldn't want to be there!

Answer 5

if you look at the temperature trends of the earth, it goes though cold stages (ice age) and hot stages, right now we are slowly moving into one of the earth's hot stages, but not to worry, it will take hundreds of thousands of years before it becomes unbearable.

humans don't give a **** so we keep messing up the atmosphere
