Whats the biggest cause of global warming?

Answer 1

human industry

Answer 2

Cars, industry that burns oil, coal, A/C systems and spray cans that use flourocarbons.

On top of this we are killing plankton and algae in the oceans and cutting down the rainforrest at an alarming rate. These restore our oxygen and consume CO2

Our desire for technology, living and industrial space is basically killing or at least harming severly the environoment, but it is not quite yet at the point of no return.

We will, ultiamtely, reach the point, whether or not we reach it by the time oil runs out (in about 200 to 300 years) is hard to say.

Once we reach that point it's hard to say if we can reverse it. We did bring Lake Erie back to life, so it is theoretically possible to re-vitalize the oceans and make lush greens on the land to rectify the problem, but it could takes centuries to cure the Earth with those little band aides.

But, they'll be a buck to be made by industry so there is a motivation and it will be our tax dollars than fund it.

America and the UK while being major offenders are no alone. Mainland China and India are vastly becoming "big pollutant" countries as are some South American countries.

By 2100 they will catch up to America in the Pollution race.

Catalytic converters, emission controls should be manditory for every car and industry in every state and every nation.

Currently only California excels in this area, with New York starting to take notice.

Be aware of the size of the problem. California has like 25 million people and there are over 55 million vehicles registered there. That's cars and trucks. Tahts 2.1 for every person in California.

That number is incredible!

There should be a registration limit of no more than 1.5 vehicles per population. No one needs 2 cars per person!

Americans.

Answer 4

It's the sun.

Let's face it, if your house was too warm, what would be the first thing you'd check? The heating, right?

So, what heats the Earth? The sun.

And when we check the sun, what do we find?

That in the past half-century the sun has been warmer, for longer, than at any time in at least the past 11,400 years!

Here's the quote...



Two centuries ago, the astronomer William Herschel was reading Adam Smith's Wealth of Nations when he noticed that quoted grain prices fell when the number of sunspots rose. Gales of laughter ensued, but he was right. At solar maxima, when the sun was at its hottest and sunspots showed, temperature was warmer, grain grew faster and prices fell. Such observations show that even small solar changes affect climate detectably. But recent solar changes have been big.

Sami Solanki, a solar physicist, says that in the past half-century the sun has been warmer, for longer, than at any time in at least the past 11,400 years, contributing a base forcing equivalent to a quarter of the past century's warming. That's before adding climate feedbacks.

The UN expresses its heat-energy forcings in watts per square metre per second. It estimates that the sun caused just 0.3 watts of forcing since 1750. Begin in 1900 to match the temperature start-date, and the base solar forcing more than doubles to 0.7 watts. Multiply by 2.7, which the Royal Society suggests is the UN's current factor for climate feedbacks, and you get 1.9 watts – more than six times the UN's figure.

The entire 20th-century warming from all sources was below 2 watts. The sun could have caused just about all of it.


And here's where you can find it...

Have a look.

Answer 5

We are told that its the burning of carbon fuels to produce carbon dioxide. But remember 500 million years ago before the coal and oil were formed all that carbon must have been in the atmosphere as CO2 and guess what - the earth survived and we evolved. So you bringers of doom take heart - its all happened before and we are still here. We aren't going to influence the Chinese or the Yanks so I'm not giving up my car yet.

Answer 6

the cause of global warming is the increased amount of aerosols (small particles) and greenhouse gases (such as water vapor (H2O), CO2, H2SO4, NH4 among other) in the atmosphere, which "traps" the heat sent out from the earths surface. The increase of these aerosols and greenhouse gases come from pollution from industry and transportation, deforestation etc

Answer 7

Remember CFCs and nearly all particulates have nothing to do with global warming. Indeed if we clean up the particulates we may have a sudden dangerous increase in temperature.

CO2 is the main culprit

Answer 8

The concentration of carbon dioxide gas in the atmosphere has increased from 290 parts per million to 380 part per million in the last 100 years. It is expect to double in the next fifty years.

Methane is a another greenhouse gas on the rise in its concentration in the atmosphere. It has increased from .8 ppm to 1.7 ppm in the last 100 years.

Some of the reasons that [C02] has risen are: buring of fossil fuels (coal, oil and natural gas), clearing forest to creat farmland, and burning firewood for heat and cooking.

Some of the reasons the [CH4] (methane) has risen are: rice cultivation, cattle production, microbial activity in dumps, the burning of tropical forests and grasslands, and release during fossil fuel productions.

Answer 10

To be honest, even though we aren't helping the situation, green house gasses would exist without our help. Although cars and air travel is a major cause, when cows fart, they release green house gasses!! So maybe its the cows to blame? Eat more beef I say!!!

Answer 11

CO2 emissions from cars, planes, lorries etc. and burning fossil fuels. The destruction of the rain forests. We need to plant more trees and get on our bikes more often!
