Its All about Gas

Global warming is caused by green house gases, which trap in the sun’s infrared rays in the earth’s atmosphere, which in turn heat up the earth’s atmosphere. The global warming has happened in the past few years and is evident from the rise in mean temperature of the earth’s atmosphere.

The "Greenhouse effect" is the heating of the earth due to the presence of greenhouse gases. It is named this way because of a similar effect produced by the glass panes of a greenhouse. Greenhouse gases naturally blanket the earth and keep it about 33 degrees Celsius warmer than it would be with without.

You maybe asking then why is all this concern about green house gasses? Well the rapid rise in greenhouse gases is a problem because it is changing the climate faster than some living things may be able to adapt. Also, a new and more unpredictable climate poses unique challenges to all life.

Now, with concentrations of greenhouse gases rising, Earth's remaining ice sheet are starting to melt too.

Greenhouse Gases also can be released into the atmosphere due to the burning of fossil fuels, oil, coal and gas. These materials are used increasingly and rampantly in Industries. Therefore Industries are also a major cause of the Greenhouse Effect. Man-made processes that contribute and are a cause to the Greenhouse effect are burning of gasoline, oil and coal. Apart from these, some farming and land-use processes are a cause of the Green house effect. Most factories also produce many gases. Which last for a longer time in the atmosphere, these gases contribute to the green-house effect and also the global warming on the planet. These gases are not naturally available in the atmosphere.

If we do not cut back on certain stuff that may cause these certain green-house gasses global warming can increase and we do not want that.

Global Warming A Health Risk

In today’s world Global Warming has been affecting nearly everything even us. The new diseases and sickness have been caused by global warming. A warmer world already seems to be producing a sicker world, health experts reported Tuesday, citing surges in Kenya, China and Europe of such diseases as malaria, heart ailments and dengue fever.

Climate changes have been affecting the amount and spread of disease by impacting the population size and range of hosts and pathogens, the length of the transmission season, and the timing and intensity of outbreaks.

Certain insects like Mosquitoes in particular are highly sensitive to temperature. The mosquitoes that can carry malaria generally do not develop or breed below about 16° C, and the variety that transmits dengue fever is limited by winter temperatures below 10° C.

But extreme heat can also be a factor, and the nexus of global warming and disease really hit home for North Americans in the summer of 1999, when 62 cases of West Nile virus were reported in and around New York City. Dr. Dickson, a Columbia University public health professor, reports that West Nile Virus is spread by one species of mosquito that prefers to prey on birds, but which will resort to biting humans when its normal avian targets have fled urban areas during heat waves.

Bird flu is another example of a disease that is likely to spread more quickly as the Earth warms up. If we do not take this as serious matter the human race may be extent because of diseases.

Wildlife Endangered ?!?

Some of the major key impacts that global warming has had in the world are on wildlife. Where in the environment animals have spent over millions of years and have adapted to shift quickly. For example ice caps melting away into water in which the polar bears have lived for years.

Beyond the different environment changing, many scientists agree that the problem is being cause by global warming. Many birds have changed their patterns of migration and reproductive habits to better adapt to the different weather change.

Some of the wildlife species hardest hit so far by global warming include caribou (reindeer), arctic foxes, toads, polar bears, penguins, gray wolves, tree swallows, painted turtles and salmon. The group fears that unless we take decisive steps to reverse global warming, more and more species will join the list of wildlife populations pushed to the brink of extinction by a changing climate.

Since the climate change has altered food availability for migratory species; birds arrive on schedule to find their food sources--insects, seeds, flowering plants--have hatched or bloomed too early or not at all.

Often overlooked, just as important as the many ways in which our climate is changing, it is changing so fast and therefore the need to address global warming is strongly encouraged. Species may not be able to adapt to this rapid climate change or to move fast enough to more suitable areas as their current areas become less suitable for them. Unless major action is taken now, global warming will likely become the single most important factor to affect wildlife since the emergence of mankind.
