When did the globe start warming?
Can anyone give me a percentage of increase in the rate since man was around? (and back it up)
There is not doubt that man "CONTRIBUTES" as the scientists broadly say, but not enough to cause a panic.
Answer:
I think global warming started when the human race learnd how to burn fuels 4 energy, and stuff like that.
In the beginning.
The temperature of the globe has gone up and down many times since man has been around. Man's affect on the environment has been almost nill until the Industrial Revolution and the damage has been increasing.
The present warming is unprecedented in 2000 years. 10 different peer reviewed studies:

There have been climate changes before, of course. But the scientific data clearly proves that, about 40 years ago, Man took control of the climate away from nature. We now control 80-90%.

We need to give it back. At the rate we're putting CO2 into the air, the warming will accelerate. That will cause damage to coasts and agriculture that will be an enormous economic disaster.
Global warming doesn't cause hurricanes, but the damage it causes to coasts is similar. Imagine dealing with a thousand major hurricanes - that's what it will be like. We won't all die, but this will be very bad unless we take steps to reduce it.

When we started to come out of the last ice age,
About 20,000 years ago. And present warming is not at all unprecidented. Further, global temperatures have been much higher than current temperatures in the past.

It is widely accepted that the last period of significant cooling was the Little Ice Age which ended around 1850 coinciding with the dawn of the Industrial Revolution and a vast increase in fossil fuel usage.
Since that time, global temperature has increased 0.8 degrees Celsius or 0.8 K. When it comes to measuring the actual heat energy you have to use Kelvin. This would give us a percentage increase of 0.28% over 150 years - in other words, even if you accept that we are responsible for 80-90% of the heat increase, that works out to one quarter of 1 percent.
Pretty disastrous, huh?
The planet cycles about every 5000 years or so. Hot and cold periods. We are just ending our last ice age. We are now entering into a warming cycle.
It started March 31, 1948
watch inconvienient truth, it's all on there. Very scary, eye opening movie
There is evidence that the Earth has been much warmer than it is now, several times before.
To rxing: yes, that's exactly the effect Al Gore wanted...for you to be VERY afraid. The left have hit pay dirt with this mantra.
From an earlier post of mine:
Global warming and cooling are cyclical events. There have been MANY ice ages. Don't they teach that in school anymore?
Greenland wasn't called "Greenland" for nothing. It is NOT necessarily caused by burning fossile fuels. The SUN's output is not constant. It pulsates.
To blame global warming on man is actually to blame it on the USA, since we are the largest consumer with the highest industrial ouput, which is to blame free enterprise and capitalism, with the hope and dreams of the left being that you will install them into total power over your life to save you from Global Warming by their installing their ideal form of government...COMMUNISM, thereby controlling EVERY aspect of your life.
Lets look at some facts:
What do the scientists tell us are the biggest greenhouse gases?
(1) Water vapor, estimated to cause 36-70% of the effect. Do you really think man's buring fossil fuels has as much to do with this component as evaporation from the oceans which cover over 70% of the planet? I guess we could also try to prespire less!
(2) CO2, estimated to cause 9-26% of the effect.
(3) Methane, estimated to cause 4-9% of the effect.
(4) Some others to a lesser extent.
Let's do some math. The worst case estimate of the increase in CO2 over the last 300 years is 85 parts per million, starting from 280 ppm. That's an increase of 30%. Let's be generous and say man's burning fossil fuels is responsible for all of that.
Now, anybody know how much of the atmosphere consists of CO2? Try just 0.035%- 0.038% = 38 molecules per 100,000 molecules of air. If there were a 30% increase from 300 years ago, and if it were all due to mankind, then, man added, where X is the original number of molecules:
(X + .30X) = 38; X=38/1.3 = 29;
Y=man's addition over 300 years = 38-29 = 9 molecules of CO2 per 100,000 molecules of air.
Can you honestly believe that 9 more molecules per 100,000 is really going to make a difference, especially if the effect is reduced by 9-26%? If you have $100,000.00, are you going to notice an increase (or loss) of $9.00?
What about methane? The PETA nuts hate it that cows flatulate and tell us that we should not have cows. Ever heard of swamp gas? Ever heard of methane gas hydrate? The ocean floor can belch more methane than all the cows (and man) combined. Scientists have shown great bubbles of methane rising to the surface could have caused ships in the Bermuda Triangle to be capsized (more plausible than space aliens).
Other gases: Ozone? Sunlight creates ozone (O3) by shining on O2. Much more than mankind can produce at ground level. And, don't we want the ozone cover to shield us from UV? You don't hear too much about the ozone hole these days, do you?
What about planting a tree (send your money to Al Gore's company to buy "carbon offsets!") ...the opposite of deforestation? Want to know where 90% of the CO2 that is absorbed to make oxygen is taken up? It's the oceans! Phytoplankton...those tiny diatoms you studied in high school (you were awake for that class, weren't you?) Grasses, shrubs and trees only contribute 10% to the uptake of C02. We could cut down all the trees (not that man would, unless you are likely also to believe in the tooth fairy and Communists' Utopia) and breathe just fine.
We actually need greenhouse gasses to live. Without CO2 there would be no O2. Without water vapor there would be no rain. Without the greenhouse effect, the earth would be too cold to grow food and inhabit. It would mostly be a giant snowball...think about it! We NEED greenhouse gases.
Why is the planet warming lately? If it is, and even this is debatable, try increased solar output. The sun pulsates...it is not constant. What can we do about it? Put on sunglasses and short-sell our beach front condos to optimists.
The scientists cannot tell us if it's going to rain on a given day next week, or when the next hurricane will hit Florida, but Al Gore can assure us Florida will be under water in just 10 years if we all don't stop breathing.
These are the realities, folks. Man-caused Global Warming is positively the greatest hoax in the history of man, for the sole purpose of guilting you into giving up your money, freedoms and your personal power to those who would gladly lord over you (in our case, the Democrats...notice that with them, there's ALWAYS a CRISIS).
The Who: "Then I'll get on my knees and pray
We don't get fooled again."
BTW, did you see the news a few days ago? It just snowed in Buenos Aires for the first time since 1918. Kinda takes the wind out of Al Gore's sails, don't you think?
According to epistemology, the "study of knowlege", the essence of knowledge is the junction of fact and belief.
Before I take a lot of time to explain the wherefore and the why of Global Warming I would like to know two things, please:
1. Are you smart enough to understand the explanation, do you have the background education to "check the facts" for yourself? and
2. Are you openminded enough to believe me when I explain to you what those facts indicate?
If the answer to either question is "no", then I won't bother answering you; or anyone else for that matter.
