is global warming happening already? give me some proofs?

Answer 1

Yes, once the ice caps were almost 7,000 feet thick over New York City. They reached down to what is now northern Virginia.

Then man came to this Continent from the land bridge, hunted the Mastodons to extinction and with their pollution destroyed the environment. Now the ice caps are a fraction of their natural beauty, only reaching to the far northern Canadian boarders.

Now scientist like Dr. Stephen Hawkins has done the work and says that the Earth will reach 450 deg F and rain sulfur if we don't do something soon!

Answer 2

These are some of the effects that have already been observed, there are others. There are expected to be more in the future...

Average global temperatures are rising faster than ever
Glaciers are retreating faster than ever
Sea levels are rising faster than any time since the last 'ice age'
The ice caps are melting
Mountain snow and ice cover is receding
Increased rainfall
Deserts have reclaimed vast tracts of land
Low lying islands have been lost to the sea
Number of floods increasing
Number of storms increasing
Number of droughts increasing
Number of heatwaves increasing
Range over which hurricans strike is extending
Animals are hibernating later and emerging sooner
Grass is growing in Antractica
Crops can be grown where previously they couldn't
Other crops are failing
Permafrost is melting
Lakes and rivers are vanishing
Insect infestation is spreading
The seas and oceans are warming up and expanding
The oceans are becoming more acidic
Ski resorts are being forced to close
Ice shelfs are breaking off the ice caps
Heat related deaths have increased
Cold related deaths have decreased
Insurers are paying out more for weather damage
Disease vectors are spreading
150,000 people a year are dying
10,000,000 a year are becoming infected
Coral is being bleached and is dying
Shellfish are less able to produce shells
Animals are migrating further towards the polar regions
Seas and lakes which froze anually no longer do
Mortality rates of polar species has doubled
Rodents are thriving
Higher levels of pollution
Contamination of groundwater supplies
Increased number of avalanches
Lowering of the water table
Habitat of many species threatened or lost
Marine food chain disruption
More wildfires
Disappearing beaches
Damage to tundra regions
Coastal erosion
Loss of wetlands and marshlands
Decline in bird populations
Extinction of some species

Answer 3

Of course it's happening. It does periodically. The current dust up over global warming is because man has tipped the scales a bit soon. As past history shows, without the advent of the late 19th and all of the 20th century industrialization, we were scheduled to hit a .1 degree rise about every century. Here it is, the 21st century and we've jumped two degrees.

Ice is disappearing all over the planet. Droughts are hitting where they have never been known before and continuing without interruption where they have been known. We've recorded more high tempatures in places than ever before. Storms are occurring more often and with greater violence than before and in places that have not historically had them.

Man has not altered the warming pattern, but accelerated it. It is like a car approaching a sharp turn. Our speed is not very great, but we keep on accelerating. Soon, we will be going too fast to make the the turn. The idea of stopping global warming is not to stop the car, but to slow it down and hopefully, keep it from reaching a very high speed so we can make the turn and begin to go back to normal tempatures as the earth naturally cools down in its normal tempature cycle. In short, to take man out of the tempature equation and allow nature to proceed normally. If we are not already too late.

Answer 4

I think that this question is one that those answering must examine very carefully. There are many facts that point to a global warming event in the last few decades. This event, though, has yet to be officially pr oven by anyone and is still unacknowledged by many scientist. The earth and its atmosphere experience many cycles and patterns, and many say that this warming event is just the latest in one of the earth's cycles, as we know that the earth goes through periods of warming and cooling. The average temperature of the earth is on the rise, that is a fact, but the reason for that is debatable. Whether this event is caused by something man has done or is simply another step in a cycle, it should be a warning heeded by all. Many of the things we do, even if they are not causing global warning, are unhealthy for the earth and all of its inhabitants, if we do not, it could have grave repercussions. There are many bad things that may happen if this trend continues, including loss of wildlife, rising of ocean levels resulting in the disappearance of Japan, Hawaii, and hundreds of miles of land on the East and West coast.

Answer 5

Here are some proofs:

A chunk of ice the size of Rhode Island broke off of Antartica because of global warming.

Canada has lost the majority of its ice over the last 100 years.

Storms are becoming more severe.

Answer 6

the version in "greenhouse gases" quantities to approximately 3.14 W/m^2 boost in "forcing" simply by fact that 1750 (see CDIAC link). the entire quantity of the solar's warming totals 1353 W/m^2, so as that's approximately 0.23 p.c., up from 1750, the Little Ice Age. It became advantageous to have issues heat up a fragment of a level simply by fact that that component, and those (14 p.c. human; see cdiac link: FAQ #7) greenhouse gases (that are regularly a results of the organic heat-up) have a minimum result, and universal climate alterations have been exaggerated in the downstream media in accordance to their own self-serving tendency in the direction of sensationalism.

Answer 7

GW has already happened.

The simplest proof is that provided by Mr. Jello. The last Ice Age is gone. How else, other than the earth warming up, would you account for it?

Answer 8

Yes, it has been warming at about 1 degree per 100 years for hundreds of years.

See co2science.org also for some actual temperature data for your area.

Answer 9

Yes, most scientists admit the earth has gotten warmer for the last 100 years mainly due to human CO2.
Actually it has gotten warmer for the last 15000 years, which helped melt the polar icecaps that covered much of the earth.

Answer 10

Yes. The lakes I fish were made by retreating glaciers. That's proof it happened even without man's tampering.
