If global warming continues unchecked, it will cause significant climate change, a rise in sea levels, increasing ocean acidification, extreme weather events and other severe natural and societal impacts, according to NASA, the EPA and other scientific and governmental bodies.
Trends in Ecology and Evolution, in press email: Although more greenhouse gases are emitted in the Northern than in the Southern Hemisphere, this does not contribute to the difference in warming because the major greenhouse gases persist long enough to diffuse within and between the two hemispheres.
But the number is not important: Carbon dioxide CO2 and other greenhouse gases act like a blanket, absorbing IR radiation and preventing it from escaping into outer space.
This colorless, odorless gas also is released when organic matter including fossil fuels like oil or gas is burned. Carbon dioxide has a lifetime of a century or more, and as such, changes in aerosols will only delay climate changes due to carbon dioxide.
Looking at the bigger picture, government oversight and sloppy industrial practices on the part of big companies has also exacerbated our pollution problem. People think that is sustainable but it is not sustainable. They include the following diverse effects: Clearly, this planet-wide domination by human society will have implications for biological diversity.
Data analysis of extreme events from until suggests that droughts and heat waves appear simultaneously with increased frequency.
Attributions of emissions due to land-use change are subject to considerable uncertainty. Global warming has led to decades of shrinking and thinning in a warm climate that has put the Arctic sea ice in a precarious position, it is now vulnerable to atmospheric anomalies.
Once cut down, they can no longer take in carbon dioxide, and this gas begins building up in the air instead of fueling the growth of plants. Problems of global warming, climate change, and their various negative impacts on human life and on the functioning of entire societies are one of the most dramatic challenges of modern times.
Human activity is most likely responsible for climate warming. As soon as an article about climate change gets published on the internet, it usually doesn't take long for comments voicing doubt or outright denying that it's human-caused to appear.
The principal motivation for his research is to identify ways and means of reducing extinctions and mitigating the worst ravages of global change.
Observed Arctic shrinkage has been faster than that predicted. You'll however often be hard pressed to find this conensus on the internet. Regional effects of global warming and Cold blob North Atlantic Difference between average temperature in — compared to the period, showing strong arctic amplification.
We must reduce emissions of greenhouse gases beginning now. Giaever was also one of more than co-signers in a March 30, letter to President Obama that was critical of his stance on global warming. How can you think it can measure this to a fraction of a degree?
Biosphere Overall, it is expected that climate change will result in the extinction of many species and reduced diversity of ecosystems. Scientists refer to these pollutants as greenhouse gases. Carbon Capture and Sequestration Carbon dioxide capture and sequestration is a set of technologies that can potentially greatly reduce CO2 emissions from new and existing coal- and gas-fired power plants, industrial processes, and other stationary sources of CO2.
We frequently hear about the number of scientists who support it. This could lead to landslides and increased seismic and volcanic activities. Contribution of natural factors and human activities to radiative forcing of climate change.
Climate change feedbackClimate sensitivityand Arctic amplification The dark ocean surface reflects only 6 percent of incoming solar radiation, whereas sea ice reflects 50 to 70 percent.
Although these models do not unambiguously attribute the warming that occurred from approximately to to either natural variation or human effects, they do indicate that the warming since is dominated by anthropogenic greenhouse gas emissions.
This could lead to landslides and increased seismic and volcanic activities. He has published two books and over scientific papers on various aspects of human impacts on the natural environment and biodiversity, including climate change, deforestation and overexploitation of populations.
In the second row: I really worry about that. One climate commitment study concluded that if greenhouse gases were stabilized at year levels, surface temperatures would still increase by about 0. The greenhouse effect The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way.
I think Obama is a clever person, but he gets bad advice. Manhattan alone has already dreamt up ways to deal with the potential rising tides over the next few years, but coming up with solutions after the fact is not enough.
Attributions of emissions due to land-use change are subject to considerable uncertainty.Without the greenhouse effect, life would probably not exist. does increasing the amount of carbon dioxide enhance the warming effect?
The evidence says yes it. Examines the science and arguments of global warming skepticism. Common objections like 'global warming is caused by the sun', 'temperature has changed naturally in the past' or 'other planets are warming too' are examined to see what the science really says.
Henry Ford’s Amazing "Hemp" Automobile Not many people know that Henry ford once built a car constructed of a plastic made from farm crops. He envisioned auto engines built to run on bio-diesel manufactured from hemp, although the engine made for his first Model T. The greenhouse gases that impact the gradual warming of the earth’s surface are those that stay in the atmosphere for a long period of time and build-up over time.
In spite of their relatively low atmospheric concentrations, their long lifetime makes their influence on global warming large. Ten years ago, Al Gore claimed we had 10 years to save the planet from global warming, as pointed out in this Communist BS (CBS News) report from early Unless drastic measures to reduce greenhouse gases are taken within the next 10 years, the world will reach a point of no return, Gore said.
Climate change poses a fundamental threat to the places, species and people’s livelihoods WWF works to protect. To adequately address this crisis we must urgently reduce carbon pollution and prepare for the consequences of global warming, which we are already experiencing.Download
