Global Warming..Fact or Fiction?


Sunny Fuerteventura ; a comprehensive guide to the Canary island of Fuerteventura.










Most popular weather predictions in global warming articles:

Temperatures will rise – Anywhere from about 2 to 10 degrees Fahrenheit, as a global average.

Some areas will be colder – Caused by the desalination of parts of the ocean and suppression of the Atlantic Gulf Stream, which keeps the northern hemisphere mild. This is the possible experience shown in last year's movie The Day After Tomorrow.

Areas will be wetter – The Great Plains and US southwest, for instance, according to some researchers.

Areas will be drier – Generally, the pattern of rain and drought is predicted to change, though exactly how remains up for debate. Dispute, in fact.
5. How does the increasing population affect global warming?
The most obvious consequence global warming articles point out is that with more people, there should be more man-made greenhouse gases, unless people suddenly become aware of their consequences and change their activities accordingly.
6. How does the concentration of carbon dioxide affect the world?
True facts on global warming:

It is first on many greenhouse gas lists found in global warming articles. This is because there is so much of it being produced, and it is the subject of Kyoto and similar agreements. Greenhouse gases trap heat energy trying to escape from the planet's atmosphere. It normally goes out through virtual windows, which are becoming plugged. Incoming energy comes through different windows that are not blocked as completely.

If there is enough CO2, we all would suffocate due to a decreased oxygen concentration. But this would take a lot. Conceivably, after a certain amount is produced, an incremental increase would have minimal effect on the global warming green house effect. That's because once that particular radiation window is filled, adding to it would be redundant.
7. What steps are being taken to prevent as much as possible the increase in global warming?
Some global warming articles mention these ideas:

International pollution incentives –

* Green house gas reduction from industrial sources.
* Consumer awareness of environmentally friendly products and smart purchasing decisions.
* Green taxes and rebates.
* Global warming articles.
* Government agreements and emissions reduction, emission credits and trading.


Cars –

* Commuter challenges,
* car pooling,
* electric and energy reduced cars,
* increase transit service and awareness.


Alternate energy sources – how many can you think of? Hydrogen, nuclear, solar and wind to name a few.
8. Which regions have most at stake?
Global warming articles like to visualize disaster. A few examples…

Heavily populated low-lying areas, homes lost due to rising sea levels and flooding. Many third world areas severely affected.

Temperate regions which have not yet been subject to diseases such as Lyme Disease, West Nile and Malaria could now get them.

Agricultural areas dependent on marginal and perhaps decreasing precipitation.
9. It has been said that human activities have played a significant role in the rise of the Earth's surface temperature. Can you elaborate on that?
We are all sources of:

Heat Our breathing, animals, cars, houses, industries.
You get the point.

Green house gases Our bodies, animals, cars, houses, industries. All emit Carbon dioxide, methane (cows are famous here), or both, plus others. Heat becomes trapped and the temperature goes up.

What is global warming? Just a change in the average temperature. Many articles and websites show global warming graphs of how historical temperatures fluctuated upwards and downwards by amounts much more than we are currently seeing.

Global warming history - The earth has survived. Many of these changes occurred before man was around, so there is some question whether mankind will survive. There is only one way to find out for sure, but I am willing to bet YES.
10. With cinematography playing on such serious topics as global warming, how much truth was portrayed in the movie "The Day After Tomorrow"?
I still haven't seen it yet, but much as been written about it. Keep in mind that this is Hollywood, and sacrificing some grim reality for excitement and profit is the norm here. However, any of those things shown in the film is possible.

What about them all happening on the same day? Well...that will be decided. I'd say likely not, but some global warming articles give reasons why multiple things could occur in a sudden chain reaction, causing catastrophe.

Let's wait and see.
