No Cars During The Last Global Warming, Why Do You Think Cars Create Global Warming?

Question

NASA: 15,000 years ago there was a rapid rise in temperature in just 10 to 20 years.

15,000 years ago is less than a second when compared to the age of the earth and there were no cars back then.

NASA:
"Rapid changes between ice ages and warm periods (called interglacials) are recorded in the Greenland ice sheet. Occurring over ONE OR TWO DECADES, the warming of the Earth at the end of the last ice age "

Also, NASA data shows it was getting COLDER when CO2 levels were INCREASING. (Time periods: approx 1945-1955 and 1960-1965 and 1988-1992).

Also, the temperature level has only increased by 0.65 of a degree in the last 110 years.

0.65 degree increase
(1890: -0.2 degree. 2000: 0.45 degrees Difference: 0.65 degrees.)

Volcanoes only change the climate of the earth for a few years.

Answer 1

I dont think that global warming has anything to do with cars or any other motors. I think it's what the astronomical experts have forecasted that the sun will burn brighter and then.................?

Answer 2

Yes, climate change occurs naturally. And yes, man is the cause of the current global warming.

There are natural cycles of about 20,000 years, 40,000 years and 100,000 years that have been somewhat regular over the last 800,000 years for which we've been looking at ice core samples. (There's information from other sources such as sea sediments that goes back further, but it's not contradictory.) The information from the ice cores leads us to infer that we have been enjoying a cyclical warm period and we were about to head back into an ice age.

However, due to the buildup of greenhouse gases, the descent into ice age isn't happening. This would be a good thing except that the buildup is so huge as to send things reeling in the other direction.

This recent buildup is primarily due to deforestation, end products of fossil fuel combustion and methane produced by livestock. Right now CO2 is at a level 30% greater than any seen during the last 800,000 years and the rate of CO2 increase hasn't been seen in millions of years.

Here's some background info on climate change from a politically neutral source written about 8 years ago: http://www.lakepowell.net/sciencecenter/paleoclimate.htm .I found one inaccuracy in it. It says, "So far in the past 18,000 years, the earth's temperature has risen approximately 16 degrees F and the sea level has risen 300 feet." That directly contradicts the graph above where it shows a rise of only 5c which is 9 degrees F. Otherwise, the information seems to agree with other stuff I've read.

The 4th IPCC report was made available a week ago and said basically that the science was unassailable. It had been presented to policy makers earlier and as a result, Bush got into line in his SOTU address. And now, ExxonMobile, which had been responsible for funding most of the global warming skepticism (http://www.exxonsecrets.org/ ), just put out a statement saying basically the same thing (http://www2.exxonmobil.com/Corporate/Newsroom/NewsReleases/corp_nr_mr_climate_ipcc.asp ).

I think the discussion now is going to be more centered on what to do about it rather than whether or not it's a problem.

Answer 3

while it is true that global temps have dropped and risen rapidly before, they always are accompanied by similar rises and drops in atmospheric carbon.

Even if today's warming trends correspond to one of those warming trends, the amount of fossil-fuel emissions has the atmospheric carbon rates literally off the charts higher than any warming trend of the past 650,000 years. Correspondinbgly, temperatures could rise higher than they've ever been ,too.

Therefore, if there is anything we can do to avert that, we should. An ounce of prevention is worth a pound of cure. Isn't it easier to demand better fuel efficiency today than deal with 100,000,000s of refugees in the coming decades, after places like Florida are no more? Of course.

Answer 4

Perhaps cars are the scapegoat during this period of global warming whereas the more volatile volcanoes 15000 years ago were to blame for spewing tons of CO2 into the atmosphere

Answer 5

They don't. But they do however figure into putting money into the pockets of regimes that hate us. So, I can't figure out why anyone is still driving a gas guzzler. They must like giving their money to big oil and people who would like to see our country wiped off the face of the earth.
Have you seen "Who Killed the Electric Car"?

Answer 6

CO2 in the air causes temp. to rise. Cars and other processes cause more CO2 in the air. It's pretty basic science.
