Articles Global Warming About

This is not the time to be complacent and apathetic. We need to act positively and constructively. There is pain and destruction is imminent. We must not shy away from the truth, but "An Inconvenient Truth" can be. It's time to put our shoulders to the wheel and focused with all the concentration. With global warming going to engulf us. And if we spend too much time, we really swallow. Then you walk in the dark. We can provide the biggest disaster that we saw and spoke only to fight in the exciting films remains to be established in fact. If global warming is expanding its tentacles over us, will not continue reading this article. Why humanity will die!

Understanding global warming

Global warming is a phenomenon that occurred for some time. Our blue planet hotter because of the increased volume of carbon dioxide. tons of carbon dioxide from burning fossil fuels and nonrenewable resources such as coal, natural gas, gasoline, oil, oil shale, etc. The use of fossil fuels on a large scale began with the 16 th century Industrial Revolution in the early Great Britain and colonies of Great Britain. The Industrial Revolution witnessed the opening of the steam engine that runs on fossil fuels. But for centuries, scientists have found that gradually burning of fossil fuels is associated with high levels of air pollution. Burning of fossil fuels leads to a large percentage of harmful gases such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen, etc., left in the atmosphere. These toxic gases have a negative impact on the climate and ecology of our planet. They also have a negative impact on our health.

Emissions of sulfur dioxide and nitrogen in the water with the formation of corrosive acids, dissolve, damage irreparably damage the graves and palaces of marble.

Sulphur dioxide and water, sulfuric acid (very aggressive)

Nitrogen dioxide and water to nitric acid (strong corrosive acid)

Sustainable

Therefore, when these toxic gases in a mixture of water and form rain water, the inevitable consequence of acid rain, acid rain, such as vulgar. This acid rain can eat the surface of architectural splendor, as mentioned above. Refinery near the Taj Mahal in Agra, India released a deadly gas into the air above the mausoleum. These gases have led to the formation of acid rains, which have a devastating impact on this area was pure white marble Taj Mahal. The destruction was so great that the management of the plant will be developed by the Government of India, and environmental activists. The factory was ordered to reduce their emissions to reduce the high level of production and close some of its activities on a beautiful monument and the tomb of Mughal Emperor Shah Jahan and his wife Mumtaz Mahal (then the name of the monument) to prevent all falls to pieces. The plant has made several attempts to methods for their production, planting trees, through the development of ecological park, which currently is home to many migratory birds and rare birds. protection, and a sincere response from the plant one of the seven wonders of the modern world of decadence, reassured the government and activists. However, environmental defenders could not sleep. We hurt hundreds of companies around the world, environmental laws and regulations in their daily lives. Measures for environmental protection should be done in the long term. environmental projects in the short term and sudden provocation "ecological systems" for the sake of advertising and image quality are desirable, nor useful. Sustainable development and environmental protection are the only weapon we have to deal with global warming.

Greenhouse

The temperature on our planet is increasing because of global warming. The burning of fossil fuels will lead to emissions of greenhouse gases. Carbon dioxide, water vapor and methane, some of the greenhouse gases are known. These gases absorb infrared radiation, and to give. Greenhouse gases tend to trap heat and raising temperatures on our planet. Thus, as a result of greenhouse gas emissions, which is our planet is always heated by an enormous size and global warming in this steady rise in temperatures and parameters of the catastrophic consequences for our planet and our lives. The hot air melts the glaciers and snowy peaks of thawing. When the heat intense, ice and snow, most of the mountain ranges around the world will melt very quickly. Melted ice and snow will enter the waters of rivers and eventually into the sea, and the unprecedented rise in sea level. Swell rivers and seas overflow and flood the country. Coste vanish, plunge whole countries. In addition to flooding, extreme weather events such as heatwaves and cold periods, floods, droughts, hurricanes and other T'ikapapa global warming.

Deforestation

Deforestation is another aspect that global warming, because it causes an abnormal increase in the amount of carbon dioxide. Global warming is already installed on our planet. Nevertheless, if global warming is underway, will eliminate all existing forests of our planet, and cause complete destruction of marine flora and fauna. Thus, global warming, deforestation and global warming, which, in turn, causes the causes blurred woods. What a vicious circle!

Ozone layer

The ozone layer protects the earth from ultraviolet radiation, direct and unapologetic (UV) rays of the sun is exhausted. Some gases better than chlorofluorocarbons (CFCs) and halons and CFCs or hydrobromofluorocarbons produced by our industry as we know, the food ozone. Aerosols produced various industries because of the ozone layer wear away. Ata ozone hole or depression in the ozone layer, usually a hole in the ozone layer. As the ozone hole is growing in this area, more UV rays penetrate the Earth's atmosphere as possible. Elevated levels of ultraviolet radiation in the atmosphere make our planet uninhabitable. Excessive exposure to UV radiation leads to the development of skin cancer and cataracts in humans. Excessive exposure to UV radiation also causes irreparable damage to many species of animals and plants. The consequences of this is an incurable problem in the food chain. Ozone depletion is a very contentious issue, as professionals, as well as disadvantages. Irony (w) hole in connection with the fact that ozone is a greenhouse gas. Too much is growing, and global warming is not a sufficient population, complete skin cancer outcome.

Meltdown

This distribution differs from the economic collapse that we have recently experienced. Although we have yet again demonstrated that the feet of decline in the autumn, we, our proven, or someone did not like and does not affect if all caps melting icecaps and glaciers in the world, and if we used these phenomena, and widespread fear of global warming.

We are ready ...?

Unfortunately, I'm not ready to face a catastrophe of this magnitude. We have divided among us, to reduce emissions in countries and to what extent. At various meetings and conferences at the highest level, we only discuss the numbers, levels and prices, and the land is ticking biological clock threatened. There is no unity among all developed countries, developing and underdeveloped countries because of global warming. Everyone agrees that global warming is a threat to universal disaster and spells destruction. But the big question: which country has jurisdiction and that the country should take the initiative to sharply reduce harmful emissions. Blame blame and Buck everywhere, and pointed accusing fingers, increasing the burden of proof, and allegations against the prosecution and it seems that on the agenda, while global warming continues to constantly engulf our planet. Developed countries are always ready to correct the pressure and intimidation in the less developed countries, as well as supporting LDCs to developed countries, the slogan of hoarseness. Mercury does not show signs of weakness. You can shoot at an alarming rate, and the policy is a step ahead of speeches, debates, heated mirrors, power and domination.

Real enemy

What the hell are we all, for all of us? Time is running out. Get up, wake up, all you dream and stop the controversy and strife. We want another disaster like what happened 65 million years, and erased all the dinosaurs on Earth? No, we want to be destroyed. And it keeps us united against a common cause? What prevents us put aside our individual problems? Because in reality we are all made from the same creator. Rather than emphasize that because we have decided to forget and focus on our differences a number of other walls that we built our country into a nation, race, state by state, race, and man by man? There is a big enemy of global warming? Enemy who is in ourselves?

The choice is ours. If we work together and make concerted efforts to avoid global warming, or let the enemy within us, to create several groups with us and beat us all. If we keep the enemy at a distance, for us, we will eventually overcome all of us. And if we, the people of 21 century living in this beautiful, middle and base enough to prefer the power and political interests should be protected, and racism, and not threaten our planet, we must win by heating in general. Because our opponents do not seem to global warming, but ourselves.

Abrupt reversal detected in Arctic cooling trend

David Perlman, Chronicle Science Editor

The Arctic climate has been warmer over the past decade than during any 10-year period in 2,000 years, according to a study by an international research team that adds powerful new evidence that human-generated greenhouse gases have speeded the pace of the planet's recent warming.

The report from an international team of climate scientists concludes that climate change in the Arctic has accelerated since the Industrial Revolution, abruptly reversing a long-term worldwide cooling trend.

"The study provides a clear example of how increased greenhouse gases are now changing our climate," said Caspar Ammann of the National Center for Atmospheric Research in Boulder, Colo., a co-author of the report published Thursday in the journal Science.

To deduce the Arctic's decade-by-decade climate trend over the centuries, the leading scientists in the international study analyzed sediment cores in 14 Arctic lakes that revealed the varied growth rates of long-buried plants. They also studied Arctic tree rings to determine their growth rates and ages as well as ice cores from glaciers across the Arctic that showed patterns of relative warm and cold.

Researchers at other institutions, seeking to look for patterns of climate change even further back in time, used astronomical records to study the well-known wobble of the globe as it spins on its axis. They found that the Northern Hemisphere has long been moving away from the sun's warmth. During the summer solstice, the Northern Hemisphere is now a million kilometers - about 621,000 miles - farther away from the sun than it was 2,000 years ago, according to the scientist's computer models.

The result was a global period of relative cold that would have continued, the scientists found. But about 1850, at the beginning of the Industrial Age, the planet's climate began overcoming the cooling trend, and the Arctic climate has warmed decade by decade ever since as greenhouse gas emissions have increased, the scientists say.

Stephen Schneider, a Stanford climate expert and biologist who did not participate in the study, called the seven-year study, involving seven major research institutions in three nations, "a heroic effort."

The study, he said, "shows that nature has been, unfortunately, cooperating with theory and showing us on a long-time scale of millennia that the mainstream view is once again bolstered."

It is clear again, Schneider said, that anthropogenic influences - the increasing emission of greenhouse gases into the Earth's atmosphere - are the prime cause of global warming.

Schwarzenegger to Obama cabinet: Water... please!

SAN FRANCISCO (Reuters) - California Governor Arnold Schwarzenegger has demanded that President Barack Obama's cabinet rethink federal policy that would divert water from parched farms and cities to threatened fish, his administration said on Wednesday.
California's rivers used to brim with salmon and sturgeon, but a massive system of canals diverted water that fed farms and cities, now suffering through a third year of drought.
Schwarzenegger has gained credibility as an environmentalist for his push to curb greenhouse gases but he argued that federal plans to save fish will worsen a water crisis that has cost farmers more than $700 million and caused mandatory rationing in cities of the most populous state.

Popular thinking about how to improve food systems for the better often misses the point, according to the results of a three-year global study of salmon production systems. Rather than pushing for organic or land-based production, or worrying about simple metrics such as "food miles," the study finds that the world can achieve greater environmental

benefits by focusing on improvements to key aspects of production and distribution.
For example, what farmed salmon are fed, how wild salmon are caught and the choice to buy frozen over fresh matters more than organic vs. conventional or wild vs. farmed when considering global scale environmental impacts such as climate change, ozone depletion, loss of critical habitat, and ocean acidification.
he study is the world's first comprehensive global-scale look at a major food commodity from a full life cycle perspective, and the researchers examined everything -- how salmon are caught in the wild, what they're fed when farmed, how they're transported, how they're consumed, and how all of this contributes to both environmental degradation and socioeconomic benefits.

Flower Power Made Our Climate Grow

This is a startling and completely unexpected result. I am totally cognizant of the powerful role of transpiration in sustaining rainfall over ecology.  The great tropical rainforests are convincing demonstrations.  It is core to my proposal to restore the Sahara and the Asian dry lands.

That it was way more difficult before flowering plants was not obvious at all.

This suggests that upland habitat was typically dryer and way more extensive everywhere except local wetlands.  Suddenly Northern Australia looks like home for dinosaurs and the whole remnant ecosystem.

This also suggests that flowering plants are way more proficient at absorbing carbon.

The rainforests would likely have been hugely constrained to their best drainage and wetlands with intervening dry highlands.  The deserts may not have been much larger but plenty of land would have been seriously marginal.  Again think about Australia.

Flower Power Makes Tropics Cooler, Wetter

http://www.sciencedaily.com/releases/2010/06/100616133327.htm

ScienceDaily (July 19, 2010) — The world is a cooler, wetter place because of flowering plants, according to new climate simulation results published in the journal Proceedings of the Royal Society B. The effect is especially pronounced in the Amazon basin, where replacing flowering plants with non-flowering varieties would result in an 80 percent decrease in the area covered by ever-wet rainforest.

The simulations demonstrate the importance of flowering-plant physiology to climate regulation in ever-wet rainforest, regions where the dry season is short or non-existent, and where biodiversity is greatest.

"The vein density of leaves within the flowering plants is much, much higher than all other plants," said the study's lead author, C. Kevin Boyce, Associate Professor in Geophysical Sciences at the University of Chicago. "That actually matters physiologically for both taking in carbon dioxide from the atmosphere for photosynthesis and also the loss of water, which is transpiration. The two necessarily go together. You can't take in CO₂ without losing water."

This higher vein density in the leaves means that flowering plants are highly efficient at transpiring water from the soil back into the sky, where it can return to Earth as rain.

"That whole recycling process is dependent upon transpiration, and transpiration would have been much, much lower in the absence of flowering plants," Boyce said. "We can know that because no leaves throughout the fossil record approach the vein densities seen in flowering plant leaves."

For most of biological history there were no flowering plants -- known scientifically as angiosperms. They evolved about 120 million years ago, during the Cretaceous Period, and took another 20 million years to become prevalent. Flowering species were latecomers to the world of vascular plants, a group that includes ferns, club mosses and confers. But angiosperms now enjoy a position of world domination among plants.

"They're basically everywhere and everything, unless you're talking about high altitudes and very high latitudes," Boyce said.

Dinosaurs walked the Earth when flowering plants evolved, and various studies have attempted to link the dinosaurs' extinction or at least their evolutionary paths to flowering plant evolution. "Those efforts are always very fuzzy, and none have gained much traction," Boyce said.

Boyce and Lee are, nevertheless, working toward simulating the climatic impact of flowering plant evolution in the prehistoric world. But simulating the Cretaceous Earth would be a complex undertaking because the planet was warmer, the continents sat in different alignments and carbon- dioxide concentrations were different.

"The world now is really very different from the world 120 million years ago," Boyce said.

Building the Supercomputer Simulation

So as a first step, Boyce and co-author with Jung-Eun Lee, Postdoctoral Scholar in Geophysical Sciences at UChicago, examined the role of flowering plants in the modern world. Lee, an atmospheric scientist, adapted the National Center for Atmospheric Research Community Climate Model for the study.

Driven by more than one million lines of code, the simulations computed air motion over the entire globe at a resolution of 300 square kilometers (approximately 116 square miles). Lee ran the simulations on a supercomputer at the National Energy Research Scientific Computing Center in Berkeley, Calif.

"The motion of air is dependent on temperature distribution, and the temperature distribution is dependent on how heat is distributed," Lee said. "Evapo-transpiration is very important to solve this equation. That's why we have plants in the model."

The simulations showed the importance of flowering plants to water recycling. Rain falls, plants drink it up and pass most of it out of their leaves and back into the sky.

In the simulations, replacing flowering plants with non-flowering plants in eastern North America reduced rainfall by up to 40 percent. The same replacement in the Amazon basin delayed onset of the monsoon from Oct. 26 to Jan. 10.

"Rainforest deforestation has long been shown to have a somewhat similar effect," Boyce said. Transpiration drops along with loss of rainforest, "and you actually lose rainfall because of it."

Studies in recent decades have suggested a link between the diversity of organisms of all types, flowering plants included, to the abundance or rainfall and the vastness of tropical forests. Flowering plants, it seems, foster and perpetuate their own diversity, and simultaneously bolster the diversity of animals and other plants generally. Indeed, multiple lineages of plants and animals flourished shortly after flowering plants began dominating tropical ecosystems.

The climate-altering physiology of flowering plants might partly explain this phenomenon, Boyce said. "There would have been rainforests before flowering plants existed, but they would have been much smaller," he said.
