When will global warming start becoming dangerous to us?

Question

I know it's started already... but when will it start killing us?

Answer 1

Relax. It will NEVER kill anyone. Not you, not your grand-kids, not their grand-kids. You had better start worrying about the very REAL problem of the terrorists coming here to kill us if another liberal gets elected!
It's all another BIG LIE to distract the public's attention away from the closet communists trying to get in power and make us a nation of helpless hapless victims. "global warming" as hypes by Gore and his comrades, is as real as a $7.50 bill, which is how much you will pay for gas if the liberals get their way !!

Answer 2

Global warming from human CO2 emissions will never be dangerous because the radiative bands for CO2 (both human derived and natural) are approaching saturation so the most warming that can occur from human emissions is less than 1°C and this amount of warming only has beneficial effects on humanity.
On the other hand satellite temperature measurements are showing that the current warming trend appears to have ended in 2002 and we have been on a cooling trend for the last 4 years. Cooling is dangerous for humanity. Cooler temperatures and shorter growing seasons mean a serious drop in the world food supply. Unlike warming, if the global temperature dropped by 1°C the results would be very serious for the environment because we would be using more fossil fuels instead of less, and even though CO2 is not a problem the other emissions from energy usage are pollutants and increased energy use means increased pollution.

Answer 3

I'll preface this by saying that I'm an environmental engineer by training, this doesn't make my opinion more correct than anothers.

First, the primary driver for global warming is fossil fuel use. The oil we pump out of the ground is converted into the CO2 now in the atmosphere. CO2 harvesting and storage is a band-aid solution as it will only slow down the effect of fossil fuel use. Biofuel (ethanol, biodiesel) is basically solar power, and is the only permanent solution for our energy needs.

From all the data I have seen and the projections, global warming is already dangerous. Even though humans can use technology to adapt to most any condition, most other critters can't do this and depend on not only mean temperature, but the timing of the seasonal cycle, rain, etc. If you drive around the Big Island of Hawaii, you'll see first hand the effect of little rain vs. lots of rain in a natural system.

There are a multitude of interactions and push-pulls that drive the natural systems on the planet. The fact of the matter is that we won't know what will happen next. It only takes 1-2 killing spring frosts to wipe out a generation of birds.

I think that we'll see more dominance of insects and plants in some areas and much drier conditions in others. This will basically force lots of people to migrate and make life more difficult for many.

Answer 4

That depends on what you consider "killing us". If you mean when will the floods come, and inundate California, Florida, Mexico, and the Midwest along the Mississippi basin, I would hazard to say within the next ten years in my opinion. Already the mold count is up dramatically, the pollon count is skyrocketing due to plants blooming sooner, and living longer due to the warm weather lasting longer.

High heat and humidity also causes bacteria and viruses to reproduce quicker, which means it also can change into another, deadlier form quicker as well. With the warming of the oceans, plankton, which produces the most oxygen for this world is dying off. Couple that with the deforestation, and pollution being put out by the big oil companies because the laws have been changed to allow them to pollute without concern of paying any fines, and you have a nightmare in the process of happening.

Isn't it a lucky thing to be alive to watch the destruction of the earth, and all that live upon it? The next thing you know, some "buckethead" in the government will start considering the possibility of a nuclear winter to counteract the greenhouse effect, which will pretty much finish off mankind. Don't think the government wouldn't try such a hairbrained idea. They have done worst in the recent past, and are already using tactical nukes in places like Afgannistan, and Iraq.

Answer 5

Hello:

Global Warming will probably start killing off sections of the world's populations when crops, start failing, animals being raised for food can't be consumed due to the poisonous chemicals in the meat., and the world's fresh water supplies become contaminated. I would think that the global warming effects that are taking place right now, around the world, are already killing innocent people through weird weather patterns, flooding in low-lying areas, reverse of the polar caps, Artic iceflows melting creating nightmares for Island nations with the rising sea levels, earthquakes and volcanic activities. Exactly when this will be completed, I am not the person to answer that question. But the member nations of OPEC probably could, since it's their product that is creating and continues to create these problems for the world. They are more interested in making money than worrying about what their product (oil) is doing to the world.

Perhaps this new source of unlimited electricity that I have discovered will put OPEC out of business, and then, they can eat and drink their rich deposits of oil. And, the damages being done to the world's ozone layers can be reversed, saving the lives of billions of people as well as the very world in which we all live in on the Great Planet Earth!
Thank you!

Answer 6

Global Warming is a process that is completely natural and is part of the earths cycle, it's just that now we are speeding it up dramatically. So lets say that the Earth is due for a warming up period in about 100,000 yrs ( this more than likely would happen, if we leave things the way the are ), but with Global Warming and Green House gases this could be Halved or more!
Yes there have been more frequent violent storms and Tsunamis etc..but could this also be part of the natural cycle of the planet, and any major Natural Disaster nowadays is put down to Global Warming etc...this is because we are now more aware of what we are doing, and the Media etc are cashing in on peoples fears.
So i don't think it will start killing us anytime soon, but don't hold me to that!

Answer 7

Global warming will become dangerous when coastal areas experience extreme winds, storms and flooding, as in Hurricanes Rita and Katrina. Also, when so much ice is melting at the poles that the Inuit natives can no longer hunt and fish and build igloos, such as in the lawsuit filed by the Inuit against the US for loss of their traditional way of life and habitat two years ago.

So I guess global warming has already started becoming dangerous to us.

Answer 8

The damages already started. It is dangerous now a day because of the temp changes. Many people are still not convince of the damages to our environment. In a few years, it is stimated that drinking water will be scarce. Even though ocean water levels are going up...that is not posible to drink. There is machinery that can process the water and making it usable. this is very expensive. If the temps keep going high, then the poles will melt even more letting Methane to escape. Methane is a gas trapped on rocks and dangerous to all us. Many polar bears are sinking because the lack of ice floating in the water. they have to travel long distances from 1 ice to another. Most of the time, they don't make it. The constant sun exposure give cancer too.

Answer 9

The rise in global average sea levels has remained fairly constant at around 2.5mm/year, or around an inch every 10 years. In 100 years the oceans could rise about 10 inches, which might have some minimal impact on extremely low lying areas.

Since most of the World's food production occurs in the higher latitudes, extended growing seasons and ranges thoughout Canada and Asia will dramatically increase the World's food supply, which will offset the couple of inches the seas will rise in total impact to humans.

Answer 10

Well I don't think this affects our generation, but our grandkids and maybe even kids could suffer from the effects. It's scary because I learned in an astronomy class that it's not only pollution that causes it but just something that is due to happen to Earth, much like the last ice age. It's a combination of both. Of course minimizing pollution and learning how to conserve all of the limited natural resources helps a hell of a lot.
