How can we prevent global warming?

Answer 1

take care don,t use spray don,t waste water and electricity don,t pollution

Answer 2

Actually the temperature of the earth has increased less than 7/10 of 1 degree (C) from 1880 to 2005. That is an increase of about 1 degree (F) in 125 years. You may choose to believe that is global warming or you may not. Source: http://data.giss.nasa.gov/gistemp/2005/2005cal_fig1.gif There are numerous charts all over the internet showing the same. Some say that 1 degree is enough to impact the global climate, others say it's not. Most proponents of global warming think the earth's temperature has risen much more than that and don't even know that it has only risen by 1 degree. But the charts do not lie as do the proponents on both sides of this issue. The average temperature in Antarctica is 109 degrees below zero. Source: http://en.wikipedia.org/wiki/Antarctica#Climate It seems to me 108 below (one degree warmer) is still pretty cold and not enough to melt anything. But there are those that say it will.

Back in the '70s all the hype was about global COOLING and another ice age was coming. I remember that they blamed pollution for that too. They said that all the pollution was darkening the skies and not as much sun was coming through so the earth was cooling off. It took many years to discover that they were mistaken and it was all just hype. Source: http://en.wikipedia.org/wiki/Global_cooling So when someone says, "the sky is falling" don't believe everything you hear on either side of the issue. There are Spin Doctors galore out there.

Most of the time people will form an opinion and not really be informed about the subject with which they become so opinionated about. So it's best that you not form your opinions from other's opinions, (as in this forum) but on the facts presented. (Many do not provide any proof or links to prove their point, just their opinion.) With that said we do have a responsibility to do our part by doing whatever is within your power to keep our planet alive and well.

I hope that helps...

EDIT:

Another site http://epa.gov/climatechange/kids/bigdea... from the EPA stating the global temperature has increased less than 1 degree over the past century. All the global charts show similar temp changes. None of them show any more than that. You need to compare apples to apples here and stop the manipulation of what is being said.

The second reference I gave says, "Temperatures reach a minimum of between -85 °C and -89 °C (-121 °F and -130 °F) in the winter and about 0 °C (32 °F) higher in the summer months." If you AVERAGE the winter temps given with the summer temps, you come up with -109 degrees average for the year. You HAVE to take the minimum and the maximum to get an average. I'm surprised you don't know that.

Next you go on to say, "Scientists are predicting..." It's what they do, they say, "it could, it may, maybe, probably, we predict..." Where are the FACTS in predictions and maybe and probably? The truth is there are no facts in those words. They keep their jobs by keeping the hype going... most people can see that.

You have played down the temps in Antarctica, when my facts are accurate.

Sorry but that won't work in this forum... You can fool some of the people some of the time, some of the people all the time, but you cannot fool all the people all the time.

Answer 3

The first answer betrays the real reason for the global warming hysteria. A loathing for human beings and modern industry. I would have to assume that it reveals a self loathing though most of the self loathers try to put themselves on a pedestal and tell the rest of us how we should live. The answer is why would we want to prevent global warming. I realize the hysterical answers from the left (and yes it is purely a political not scientific debate). Warming is generally good. I think the left might not be satisfied unless we went back to ice ages with glaciers everywhere and nothing fit for anything except a Neanderthal. In reality, it is a far better world warm than cold. The temperature of the earth as well as the ocean level changes over time. We are in a warming trend which we should be thankful for.

Answer 4

We can't prevent it; it's too late for that. We can only slow it down and buy more time for our scientists and engineers. Reduce, reuse, recycle, repair.

walk, ride your bike, switch to florescent lighting, drop your thermostat and wear a few more layers, turn stuff off when you're not using it, buy energy efficient appliances / vehicles / electronics, have less children, stop eating beef (methane gas producing)

To continue mattzcoz's education of CapNemo: Your number for average temp in Antarctica is incorrect. Reread your source. That's the number for the minimum. The average is -58 F. But that's the number for all of Antarctica. At the coast where the ice is melting, the temp is much higher. As the offshore ice melts, the ice on the land slides down into the ocean where it too melts. This is what has already started causing the sea level to rise. The level is expected to rise about 3 feet. We have just experienced the chaos of trying to relocate a single city - New Orleans. Imagine what's going to happen when all the coastal cities have to relocate. These are our ports and our harbors. I don't think you get it it, buddy. Wake up!!

Answer 5

Reduce? Consume less of everything (electricity, goods, clothing, gas/energy, meat, etc.) When you do have to buy something, try and purchase things that have been shipped as short a distance as possible.

For people like capnemo, who keep publishing unscientific/controversial materials on here, I offer the following:

Average global temperatures have changed about 1C since 1880, or 1.8F, not "...about 1 degree (F)...". Of course, that may still sound comforting until you study the subject a little more. The rest of his points do not address the issue and so can largely be ignored. The only pertinent "fact" he quotes is off by 80%.

From a Pentagon-funded/published national security study...
An Abrupt Climate Change Scenario and Its Implications for United States National Security
October 2003
By Peter Schwartz and Doug Randall
http://www.climate.org/PDF/clim_change_scenario.pdf
"...The research suggests that once temperature rises above some threshold, adverse weather conditions could develop relatively abruptly, with persistent changes in the atmospheric circulation causing drops in some regions of 5-10 degrees Fahrenheit in a single decade. Paleoclimatic evidence suggests that altered climatic patterns could last for as much as a century..."
"...because of the potentially dire consequences, the risk of abrupt climate change, although uncertain and quite possibly small, should be elevated beyond a scientific debate to a U.S. national security concern."
"Following the most rapid century of warming experienced by modern civilization, the first ten years of the 21st century see an acceleration of atmospheric warming, as average temperatures worldwide rise by .5 degrees Fahrenheit per decade and by as much as 2 degrees Fahrenheit per decade in the harder hit regions. Such temperature changes would vary both by region and by season over the globe, with these finer scale variations being larger or smaller than the average change. What would be very clear is that the planet is continuing the warming trend of the late 20th century."
"As temperatures rise throughout the 20th century and into the early 2000s potent positive feedback loops kick-in, accelerating the warming from .2 degrees Fahrenheit, to .4 and eventually .5 degrees Fahrenheit per year in some locations. As the surface warms, the hydrologic cycle (evaporation, precipitation, and runoff) accelerates causing temperatures to rise even higher."

There is much more information available to buttress the effect of mankind on the climate and the effects of climate change on life as we know it. Regardless of the cause, the outcomes are catastrophic for current lifeforms. ANY intelligent effort to address the problem is worthy, just as all efforts to ridicule the whole concept are childish.

Answer 6

Two ways are in place in Europe, not enough but it reduced emissions by 5% while economy grown. Now goal will be a bit more agressive 20%-30% reduction, still not enough, but better than nothing.

1st way. Change of fossil based electricity production plants by other technologies, mostly wind. Its approach is business. Anyone landowner can use land to produce electricy and sell it to electricity operators. By law, they MUST buy that power at an agreed price (average electricity production place). Banks lend money tolandowners if necesary because business is zero risk. Electricity operators reduce investments. Governments deduct taxes to landowners and reduce health care costs due to respiratory track deseases.

2nd way. Zero-emissions coal plants. It is in place in almost EU-12 countries. That technology will be mandatory for oil and gas plants within the next two years.

A third way is starting this year as soon as some european car manufacturers have launched their first cars:
3nd way. Hydrogen, hybrid and alcohol fueled engines. Still an small market but growing fast. Extra-tax for fossil fueled cars and tax reductions for "green" cars.

Answer 7

We can't. Paleontology shows us the globe has warmed and cooled all on its own many many times. We might slightly diminish our contribution to it, but we can't do much without ending our fossil fuel consuming civilization and killing 5 billion people. And one big volcanic outburst could overshadow centuries of our contributions. The dinosaurs we dying off long before the asteroid finished them.

Answer 8

Not with technology available today. It would take an effort and equipment only available in science fiction stories to accomplish such a feat. Something along th elines of "terraforming".

Answer 9

we could try to use hydrogen fuel cell right now. It is a renewable energy, 0 percent emmissions. Some buses in london are powered by such fuels and it works very well.

Answer 10

We can't, it's to late, we can thank our fathers and grandfathers for it, and today, we can thank all those countries who will absolutely not, stop or at least reduce harmful emisions.
