Global warming affects human health positively

A new and extremely contradictory statement regarding global warming has been recently made. Three groups of global warming researchers now claim that global warming is not that harmful for human health and for the environment, as it was thought. Quite the contrary, global warming is likely to have a positive effect on human health.

In the new “Climate Change Reconsidered: 2011 Interim Report” it’s stated that greenhouse gases do not influence climate change at such a rate as previous reports asserted.

However, the conclusions of the study contradict the findings of the widely cited reports of the IPCC and many climate research organizations.

The report says that “global warming is more likely to improve rather than harm human health because rising temperatures lead to a greater reduction in winter deaths than the increase they cause in summer deaths.”

The reports also states that the Medieval Warm Period of approximately 1,000 years ago was both “global and warmer than today’s world.”

That’s one more proof that scientists are usually in twenty minds. There’s nothing wrong about changing your point of view, it’s even cool to be able to change your position and accept another one. However, it should also remind us that there’s no point in believing every word scientists say, and it’s a good idea to accept the possibility of other things being probable. That also makes me think of year 2012, “the END of the World” lol

Global warming helps gardeners

Everyone knows that the climate in UK is not the proper one for various plants and flowers to be grown up there. Actually there’s a striking fact about the exotic flora in UK. Now gardeners are able to grow fig trees and date palms that are becoming increasingly popular. The cause is global warming as experts suppose. Because of warmer temperatures exotic and tropical varieties start to bloom what is basically impossible for the climate of UK. New Scientist has recently reported the spread of wild mushrooms across the UK which is also caused by global warming.

Besides it’s become easier for gardeners to cultivate tropical plants in ordinary gardens, so they take the advantage of the warmer climate.

"Plants such as the Canary Island date palm, olives, fig trees, bananas and the bottle brush bush are all becoming popular."

Step it up - stop global warming!

On April 14 2007, Saturday was a national day of protesting against Global warming. There are about 1410 actions that are happening under banners "Step it up, Congress! Cut carbon 80% by 2050"

Step it up was found in January, 2007 by environmentalist and a writer Bill McKibben, who's also the author on the stepitup2007.org. The goal is to reduce greenhouse emissions 80 % by 2050. That's why different events are being organized all over the US.

Also the fact of rising of the ocean level is pressuring. Scientists say melting of polar ice caps and glaciers will cause sea level rise. The Intergovernmental Panel on Climate Change has projected that the sea level is likely to rise 7 to 23 inches this century, but other scientists believe it can rise 10 feet or more, which is enough to flood Lower Manhattan and other low-lying coastal areas.

Depressing predictions about global warming and the future has been already made. Cutting down the level of carbon in the atmosphere is a big and serious step that The Congress should focus on.

Maine Gov. John Baldacci said at the meeting in Portland:

"The most important things that we have a responsibility to do in government are to prepare our children for a bright future and to preserve and protect our natural resources,"

Now it is exactly the time to act, until it's not too late. You can be a part of this great action. Just sing it up.

What's wrong with the Earth ?

Some of the global environmental problems you should know.

Global environmental problems are much spoken nowadays. The ecology of the Earth is becoming worse and worse each year. Scientist are making predictions about the future of the Earth that are closely linked with such global problems as global warming, greenhouse effect and gases, ice melting. I want to inform you and to give you an idea of them.

So, here we go:

Greenhouse effect is the process in which the emission of infrared radiation by an atmosphere warms a planet's surface.The main problem is a raise of carbonic dioxide (CO₂) in the atmosphere. In a common usage, "greenhouse effect" may refer either to the natural greenhouse effect due to naturally occurring greenhouse gases, or to the enhanced (anthropogenic) greenhouse effect which results from gases emitted as a result of human activities.On Earth, the major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%.

The increased CO₂ in the atmosphere warms the Earth's surface and leads to melting of ice near the poles. As the ice melts, land or open water takes its place. Both land and open water are on average less reflective than ice, and thus absorb more solar radiation. This causes more warming, which in turn causes more melting, and this cycle continues.

Look the process of the Greenhouse effect

The green house gases are components of the atmosphere that contribute to the Greenhouse effect. Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities add to the levels of most of these naturally occurring gases.

The Antarctic ozone hole is an area of the Antarctic stratosphere in which the recent ozone levels have dropped to as low as 33% of their pre-1975 values. The overall cause of ozone depletion is the presence of chlorine-containing source gases.

In the presence of UV light, these gases dissociate, releasing chlorine atoms, which then go on to catalyze ozone destruction. The Cl-catalyzed ozone depletion can take place in the gas phase, but it is dramatically enhanced in the presence of polar stratospheric clouds (PSCs).

The role of sunlight in ozone depletion is the reason why the Antarctic ozone depletion is greatest during spring. During winter, even though polar stratospheric clouds are at their most abundant, there is no light over the pole to drive the chemical reactions. During the spring, however, the sun comes out, providing energy to drive photochemical reactions, and melt the polar stratospheric clouds, releasing the trapped compounds.

Ecology

Ecology is the scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment. The environment of an organism includes both physical properties, which can be described as the sum of local abiotic factors such as insolation (sunlight), climate, and geology, as well as the other organisms that share its habitat. The term oekologie was coined in 1866 by the German biologist Ernst Haeckel the word is derived from the Greek οικος (oikos, "household") and λόγος (logos, "study"); therefore "ecology" means the "study of the household [of nature]". The word "ecology" is often used in common parlance as a synonym for the natural environment or environmentalism. Likewise "ecologic" or "ecological" is often taken in the sense of environmentally friendly.

Well, the ecology of our planet is undoubtedly getting worse and worse.
