 In order to talk about global warming, we must first learn what causes the greenhouseeffect.

It’s getting clearer to me, and hopefully, to others that global warming isn’t a hoax or a future concern that we can resolve at our leisure. No, global warming isn’t good for any economy or any human.

People who hold such beliefs feel little commitment to improving present institutions or to working to solve ecological problems. Many feel that global ecological disasters are inevitably part of the "end times" that were supposedly predicted in biblical verses.

Infrared radiation is sent out by the earth through the atmosphere, where molecules (carbon dioxide) hold outgoing radiation for a while, warming the surface.1 The molecules are kind of like glass in a greenhouse which is why this process of warming is called the greenhouse effect....

Global warming is widely believed to be the main cause of rising average global temperatures.

Wow Franke, you have managed to capture this very important message in a disarmingly charming way, with an unsettling undercurrent that speaks to its seriousness. – Are we allowed to share this with teachers/students? I think it would spark some interesting and educational dialogue! – Thx – Stephanie

A general contractor in Barrow noted that the depths at which pilings for structures must be set have increased by several feet over twenty years. Warming of permafrost before the actual thawing can greatly reduce the load capacity of pilings, creating significant problems for buildings and pipelines (Hinzman, 2004). Permafrost used to make a useful medium for foundation in these regions, but the melting is presently making it very dangerous to build a foundation in. This raises the challenge of preventing thawing of ice-rich permafrost in order to avoid slumping of buildings, pipelines, and dirt roadway (Berner/Hinzman, 2004).

Is the threat of global warming real.

Global warming in essence, is exactly what it sounds like, the warming of the plant....

Polar bears live and hunt on arctic sea ice. Polar bears feed almost exclusively on the seals that they hunt on the ice edge or through the pack ice itself. Studies show that the arctic ice has already decreased by about 40% (Maxwell, 1997) and future estimates go as high as 70% (Kirby, 2000). The summer ice-free period has lengthened as well. This leaves polar bears with less time on the sea ice to hunt for food and build up their body fat stores, and increased time on land where they must fast. Newborn bears are smaller than human babies, and blind. They require weeks of nurturing before they can leave their cave, but now there are several indications that an
increasing number of cubs, and even mothers, are found dead as they cannot breathe when the snow cave collapses due to global warming. If they do survive, the young are exposed to the frigid temperatures and they eventually die as well (Ice melting under the Feet of the Polar Bear). The losses of polar bear populations will not only affect the
people inhabiting the Arctic areas, but also significant consequences for the entire ecosystem that they occupy (Berner et. al., 2004).

What does the greenhouse effect have to do with global warming.

I suspect that the population-balanced result in the inset is an artifact of computer modeling. The implication is that the rich countries are more able to resist the impacts of climate change than the poor ones. and that having caused global warming they should pay the poor countries – how much? Well, I guess having caused 64% of it equity demands that they should pay 64% of the poor countries’ costs. 😉

There is no need for assuming that global warming is not happening yet we see the changes that have taken place in the environment since we were young.

I agree with what you say.
Remember the hockey-stick computer modelling scenario of global warming? Which morphed into climate change as a major disaster for humans in spite of the fact that the geological record and history shows that that earth temperatures have varied before and after the large increase of CO2 emissions which started with the industrial revolution.
CO2 emissions do not explain the drop in temperatures after the Napoleonic war.

free essay on Global Warming

The expected affect of global warming on arctic ecosystems is astounding. Global warming will likely affect species at almost every level of the food chain, from plankton to polar bears. Arctic ecosystems already have a startlingly low number of species, and even small changes bring drastic results. According to Adam Markham, director of WWF's climate change campaign, "Arctic ecosystems are probably the most fragile and interdependent on earth" (Reindeer, 1996).

After researching many sites, such as National Aeronautics and Space Administration (NASA), University studies, Intergovernmental Panel on Climate Change (IPCC) studies, Nongovernmental International Panel on Climate Change (NIPCC), and more, global warming is very complicated.
