What is meaning of global warming?

Question

What is meaning of global warming?

Answer 1

armageddon to sum it up

Answer 2

Al Gore admit to making money on global warming

Answer 3

It is a scam that is making some Co. billions. Why do u think is causing the gasoline prices to go up?? The more u propagate GW the higher every thing will go.

Answer 4

Go read the book "The Politically Incorrect Guide to Global Warming and Environmentalism" by Chris Horner.

Answer 5

The meaning is...

Short version: Us humans screwed up and now we got to much gas in the ozone

Long version: With the millions of explanations... I'm not even gonna try

Answer 6

Here is truth about global warming:

Global warming is one-half of the climatic cycle of warming and cooling.

The earth's mean temperature cycles around the freezing point of water.

This is a completely natural phenomenon which has been going on since there has been water on this planet. It is driven by the sun.

Our planet is currently emerging from a 'mini ice age', so is

becoming warmer and may return to the point at which Greenland is again usable as farmland (as it has been in recorded history).

As the polar ice caps decrease, the amount of fresh water mixing with oceanic water will slow and perhaps stop the thermohaline cycle (the oceanic heat 'conveyor' which, among other things, keeps the U.S. east coast warm).

When this cycle slows/stops, the planet will cool again and begin to enter another ice age.

It's been happening for millions of years.

The worrisome and brutal predictions of drastic climate effects are based on computer models, NOT CLIMATE HISTORY.

As you probably know, computer models are not the most reliable of sources, especially when used to 'predict' chaotic systems such as weather.

Global warming/cooling, AKA 'climate change':

Humans did not cause it.

Humans cannot stop it.

Answer 7

the world warms up

Answer 8

More money from taxation. Not that the government will spend any extra on money on global warming  prevention.

The governments must think this is the biggest money spinner since income tax.

Answer 9

Keep in mind that the greenhouse effect is not a bad thing- without it earth would be too cold for us to live on.  Its when too many gases trap more infrared rays released by the earth than are needed to keep the climate stable is when the effect becomes a negative thing.

Answer 10

What is global warming? This is a fair question, as much written and said about “global warming”. The term is often misused and people tend ask questions like, 'do you believe in global warming?' This is a bit like someone asking an economist, whether they believe in inflation. It is difficult to know where to start when answering, What is Global Warming? This is because there are other hidden questions buried in the original one. Many people when asking the first question, are often also wanting to know if the warming is attributed to human activity ( anthropogenic ); are greenhouse gases building up in the atmosphere?; and is the warming something they should be concerned about? The short answer to all those questions is YES!

Answer 11

Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.

Answer 12

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century and its projected continuation.

The average global air temperature near the Earth's surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005.[1] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations"[1] via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.[2][3] These basic conclusions have been endorsed by at least thirty scientific societies and academies of science,[4] including all of the national academies of science of the major industrialized countries.[5][6][7] While individual scientists have voiced disagreement with some findings of the IPCC,[8] the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions.[9][10]

Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century.[1] The range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans.[1]

Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions, but there is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.
