What is Global Warming? How is it caused?

Question

Are there ways we can reverse the adverse effects of global warming?Give some lengthy answer please???

Answer 1

global warming is a knee jerk reaction to a normal cycle that isn't fully understood.

here are some of the predictions i grew up with over the past 40 years:

famine
mass death
shifting of food production regions
climate change
overpopulation
global cooling
mass starvation
massive glaciers
uninhabitable places on earth
running out of fossil fuel
pollution physically altering man (through adaptation)

all this was supposed to happen by the year 2000, and if man didn't stop using fossil fuels. we had 30+ years of "irrefutable data" showing that man caused it too.

but we didn't stop, we used more!

STRANGELY, NOT ONE PREDICTION HAS CAME TRUE YET!

now i'm supposed to "believe" global warming is "real"

Answer 2

Global warming and global cooling may I add, is a natural phenomena, a part of the Earths life. The Earth has been a lot hotter than today and I dont think dinosaurs used jet planes or cars. It's also been a lot colder in the past, such as the many ice ages.
While I admit that humans are altering the climate slightly with carbon dioxide and other greenhouse gasses. Mother nature has the final say, and shes a lot tougher than us.

Answer 3

The Earth is primarily heated from the Sun. Solar radiation comes through our atmosphere and loses energy.. this effectively traps the light until is diffuses into heat radiation. Every 10,000 years our orbit around the Sun becomes elliptical, producing periods of greater solar radiation.. therefor greater heat retention, producing natural global warming. These "greenhouse gases" that retain heat have increased due to human activities dating back to the industrial revolution and are now higher than they have been at any point in the entire existence of mankind. Many scientists believe there is a direct link between these elevated levels of greenhouse gases and our current warming trends.. leading to the theory of human-induced, or human exacerbated global warming.

Think of it like this... have you ever walked into a greenhouse? even in the winter it is warm... adding to the greenhouse gases is like putting a thicker sheet of glass on the top of the greenhouse. Take from that what you will as far as it's effects on the planet.

The length is in the links.

has everything you could want, including graphs and pictures.

Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing, mostly caused by water vapor.

Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global warming.

It won't be a Hollywood style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.

Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.

we can't reverse it with any reasonable method, but we can reduce it enough to cope with the remaining effects. Here's the plan>

Answer 5

Global warming is just the Earth returning to its normal state.

http://www.lakepowell.net/sciencecenter/paleoclimate.htm

The geological record shows that the Earth is normally hotter than it is now. For about 80 million years, during the Cretaceous and Tertiary periods the Earth's average global temperature was around 22ºC, compared to 14ºC now. For about 55 million years during the Triassic and Jurassic periods the Earth's average global temperature was again around 22ºC. For a brief million or so years during the Permian period the Earth's average global temperature was above 23ºC. For about 25 million years during the Devonian and Silurian periods, the Earth's average global temperature was again around 22ºC. For about 50 million years during the Cambrian and Ordovician periods the Earth's average global temperature was around 22ºC. There were four major Ice Ages during that time span, we are climbing out of one now.

Answer 6

Global warming refers to the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.

The global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the last 100 years. The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperatures since the mid-20th 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 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. However, a few individual scientists disagree with some of the main conclusions of the IPCC.[4]

Climate models referenced by the IPCC project that global surface temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100.[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 millennium even if greenhouse gas levels are stabilized.[1] This reflects the large heat capacity of the oceans.

An increase in global temperatures is expected to cause other changes, including sea level rise, increased intensity of extreme weather events,[5] and changes in the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, 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. 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. Most national governments have signed and ratified the Kyoto Protocol, aimed at reducing greenhouse gas emissions.

Answer 7

there is no such thing as global warming. it is a theory of someones imagination. The earth goes through climate changes all the time. Look at the last 10000000000 years, and you will see a pattern. This pattern has been put together by top scientists, but the liberals want you to think differently....

Not a lenghty answer, but the Librarians' Index to the Internet has a number of useful links that you might find useful:

A number of these sites will have more in-depth discussions of the issue.

Answer 9

Global warming is caused by politicians who want to raise your taxes and get more control over your life.

Right now in the UK, the gvmt is planing to tell it's citizens what kind of computer, DVD, TV, and refrigerator they are allowed to purchase.

Imagine being jailed for owning an illegal appliance. This is what the world is coming to thanks to the "global warming" scare.

To reverse the problem is to vote the current politicians out of office.
