Uncertinties about global warming?

Question

i need 3 uncertinties about global warming for my science class for a disscusion we r having tommorrow. and she told us we could use the internet. so what are 3 uncertinties about global warming? thx!

Answer 1

A lot of people thing the research into AGW is biased.  In particular David Deming testified before the US sennate committee on his experiences with AGW research.

Answer 2

1. It's happening and there is not a thing we can do about it.

2. It's not happening and we should not worry about what we can not control.

3. It's not happening, but the d**n governments are still going to tax the h**l out of us.

Answer 3

1.  How rapidly will it occur?  The answer depends on "feedback" mechanisms.  An example is ice melts, exposes dark ground, warming speeds up.  So far we can't calculate exactly how important the feedback mechanisms are.

2.  How many species will go extinct?  Some will adapt, some will perish.

3.  How will it affect hurricanes?  The current thinking is that there will be about the same number, but that they'll be stronger.  But we don't really know.

Answer 4

1. The media is bias.

2. Warming and cooling periods all through the 1900,s

3.  Al Gore still is not changing his carbon foot print.

Answer 5

Do you mean uncertainties as in whether or not AGW is man made or how long to take effect?

Uncertainty about CO2 having any greenhouse effect:

Uncertainty about Polar Bears becoming extinct:

Most of the Arctic land is called "Tundra" and that is where the polar bear lives.: + The Polar Bear mainly eats seals, except in the summer when they eat vegetation and berries. They are called omnivores, which means that they eat plants besides meat.:

Although polar bears are basically land animals + when many bears become "stranded" on the land as the ice recedes northward, they turn to a variety of quite different foods in the absence of seals. They also eat small mammals, birds and their eggs, and plants.:

Polar bears can easily adapt and will not become extinct!

The real problem is their overpopulation straining their food supply - hunting/thinning is one proposed solution.

Answer 7

Basically all you need is one (Ecological Homeostasis) but it has many subsets.A few are 1.Oceanic conveyor belt.2.Albedo temperature effect. 3.Polar refreezing rates. 4.decreasing/increasing habitat....etc....

Answer 8

Be sure to mention the uncertainty of computer models
