Global Warming is not About Weather Changes
from:Scientists warn about global warming and the harmful effects it has and will continue to have on our environments. Climatologists have discovered that the earth is warming up at the rate of 1 degree Fahrenheit for every hundred years. Members of the different scientific communities are already seeing the dire consequences global warming has upon our present environment and predict even worst conditions for future generations.
Though there are some scientists and laypeople who believe that global warming is a natural phenomenon, many climatologists, environmentalists, etologists and others believe that global warming is a result of human intervention directly due to the emission of greenhouse gases released into the earth’s atmosphere where it remains trapped thus warming up the earth. This condition is widely known as the greenhouse effect.
Human intervention is responsible in part to the rip in the ozone layer, the protective layering between the earth’s atmosphere and the sun’s rays. The ozone layer is thinning out because of chemicals used in aerosol spray cans and other toxins released into the air.
Many hot countries are feeling the effects of warmer temperatures and weather reports of longer hotter summers prevail just about everywhere. Colder climates are starting to see warmer winters as well. However, the truth of the matter is weather and climate, are two very different things.
What we see on a day today basis such as the temperature, rain, snow, sleet, other precipitation, wind, barometric pressure etc, is what we call weather, and it can change rapidly. A bright sunny day can suddenly change into a cloudy day with rain and thunder in no time at all. Whereas climate is a constant condition, reflected by average temperatures in a given area over a period of time. If you are living in the far north marooned at home by artic conditions you may not appreciate the concept of global warming, but remember you are experiencing the temperature at the moment, which is extremely cold and not the climate change. In fact, scientists state that humans will not feel a general one degree Fahrenheit change in the climate because it is so gradual.
That does not mean that global warming will not have telltale affects on the environment in which we live. For example warming temperatures will cause more floods and tsunamis to areas that have had very little in the past. One example of global warming that we are presently seeing is when the frigid icy waters in colder climates melt earlier than usual causing springtime flooding along coastal banks.
Scientists have been recording temperatures since 1850 and eight of the warmest temperature readings recorded in all this time was documented since 1998. The warmest year recorded in history was 2005. Scientists expect that even though the average temperature has increased at a rate of 1 percent per 100 years it can accelerate to 2 to 6 percent over the next 100 hundred years. Though this percentage increase may seem minimal, keep in mind that the during the last ice age, when most of North America was covered in glaciers, the earth was only 7 degrees colder than it is today. Any global warming climate change can cause drastic consequences that we are yet to become aware of.

Global Warming is the Real Thing, but "Global Warming" is not the real problem [Greg Laden's Blog]
As is the case with most things that are important, we as a society have done a very bad job of developing an effective conversation about Global Warming. The vast majority of electronic and real ink that I see spent on the discussion of Global Warming (outside of the peer reviewed literature) is not even about climate or climate change. Rather, it is about talking about climate change, the ...

British researchers find that methane emissions from sauropods would have far outstripped those from modern-day livestock. Dinosaurs' gassy guts may have contributed to global warming tens of millions of years ago, according to a new study that finds a group of plant-eating dinosaurs could have produced about as much methane as all of today's natural and man-made sources of the greenhouse gas.
