This video explores both convection and radiation to explain how weather is related to the transfer of heat energy. Convection occurs when temperature differences arise within a fluid, such as an ocean, and fluid motion almost certainly follows in which heat is transferred from one area to another. Movements of hot ocean currents can have profound effects on global weather. Radiation is energy traveling in the form of electromagnetic waves or photons. An example of this regarding weather would be the effect of the Sun melting an ice cap, or the greenhouse effect, whereby heat is trapped within the atmosphere.

Polar Weather
The extreme weather conditions experienced in the polar regions of the Arctic and Antarctic, where six months of near-constant daylight is followed by six months of dark winter, are detailed and explained in this video. In particular, the importance of the massive ice sheets, and how they are affected by global warming, is discussed in the video.
Summery of "An Inconvenient Truth" Film
In hundred of graphs and videos, the film shows the global environmental challenge which is global warming. It gives what the earth was and what it will be in next decades.
Global warming is increasing of carbon amount in the atmosphere because of burning process by cars or other fossil fuel sources. Carbon trapped in the atmosphere and acts like the glass surrounds the earth. As the result, when sunlight come through the atmosphere the earth warm and exceed heat can’t get out, so the temperature raises causing environmental crisis.
Liquid areas like oceans have ability to absorb much heat than solid grounds like icebergs which serves as a mirror that deflects sunlight. However, as water heats up, the polar ice and icebergs starts to shrink and melt. Because of melting ice, creatures like polar bears have to find another place to put their foot on it. In some research these bears have to swim much longer distance around 30 miles.
What does it mean to have long distance?
What are these polar bear going to do with this serious planetary effect?
Furthermore, increasing hooter weather caused not only floods of water but also droughts. Soil moisture has evaporated and the ground becomes not stead or stable. Many houses have demolished and long trees swing. Moreover, because of melting polar ice, world sea level rises. The rising could be up to 20 feet. See water covers some habitable lands and causing memorable number of consulting and losses.
My comment
The film was very interesting and worth seeing. I learned how the environmental crisis effect on the weather, sea and land. It is really a global serious problem. I learned that problem have come like result of what people do especially in last 3 or 5 decades. One of bad effects, the world sea level is rising to cover some residential areas. Hot weather is rapidly increasing because many countries turn to be industrial and the worst is coming if people don’t begin to change their behavior.

Nothing is inevitable
Time is running out. The green house problem has become most serious those days and the worst is coming. If we want to bring gas emissions down, we have to make changes in the world economy and the way we live.
Eco-friendly energy sources
Wind and solar power are both mainstream energy option available today. Wind turbines are connected with blades which turn to generate electricity. They can be used on the plains like in India or off shores like in Denmark. Growing faster than wind power, solar energy provides power for individual buildings by using light sensitive semiconductors which generate electricity.
Biofuels
They are trees, crops and farm waste that are replaced with coal ro distilled to produce ethanol. Ethanol is a fuel that could be sued in power plant or directly in vehicle engine.
The hydrogen economic cars
Hydrogen is made from water which could burn like petrol.

The safe Refrigerant
April 1930, Thomas Midglay demonstrated in meeting of the American Chemical society
how the safe new refrigerant works. He depended on liquid CFC;s and a glass dish and room temperature. After pouring, the refrigerant started to boil. At that time, the audiences and Thomas believed that refrigerant is non- explosive, non-poisonous and not harmed animals. After years, CFC had been causing global warming and house gas emissions.

To improve Abu Dhabi Environment
Dear, Environment Friends 
You don’t need to be scientist to make changes because we have power at home or while we move. Your actions start beyond when you reduce your own emissions. One way to make a positive effect on global warming is limitation of using cars. A car produces carbon dioxide. You can come from Ban Yas to Abu Dhabi by Bicycle. I don it and it doesn’t take you more than 80 minutes or from Cornich Abu Dhabi to You Collage like HCT takes 30 minutes. In home, using electricity and heat generate most emissions. As much you reduce emissions, you make energy more efficient and lower your energy bills.
~ How to take action, to be active and become carbon natural
1. Reduce your impact AT HOME
2. Reduce your impact WHILE ON THE MOVE
3. Help bring about change LOCALLY, NATIONALLY
My best Regard,
Ali

An Inconvenient Truth Film
Dear,
A new powerful documentary is worth seeing which published in 2006. The film shows the great crisis that we are in. it discusses threat of global warming and its dangerous influences. Global warming change will collapse the ice sheet which could rise global see level; as the result, there are going to be floods and lots of refuges for victims. In other world, melt water from green land causes warm northern European and cool other places. You can notice it called Inconvenient because every one effects by it and it damages our environment and our health. It is a serious issue.
