He show some nice picture of famous icy mountain now facing "melt-down", the cause...
The climate system varies through natural, internal processes and in response to variations in external forcing factors including solar activity, volcanic emissions, variations in the earth's orbit (orbital forcing) and greenhouse gases......Would this sounds like natural disaster ? well we "HUMAN" are always one of the many contributor for nature change, we can see even on movie, many creatures, mutant, so-called accident, are all started with Human. Example : Godzilla - its existent due to nuclear effect from buclear bomb.
The increased levels of greenhouse gases due to human activity as the main influence. This attribution is clearest for the most recent 50 years, other hypotheses have been proposed to explain most of the observed increase in global temperatures. Among these hypotheses are that the warming is caused by natural fluctuations in the climate or that warming is mainly a result of variations in solar radiation.
The predicted effects for the environment and for human life are numerous and varied. The main effect is an increasing global average temperature. From this flow a variety of resulting effects, namely, rising sea levels, altered patterns of agriculture, increased extreme weather events, and the expansion of the range of tropical diseases.
What Can We Do To Prevent ? Some Tips :
1) Change a light. Replacing a regular light bulb with a compact fluorescent one saves 150 pounds of carbon dioxide each year.
2) Drive less. Walk, bike, carpool, take mass transit, and/or trip chain. All of these things can help reduce gas consumption and one pound of carbon dioxide for each mile you do not drive.
3) Recycle more and buy recycled. Save up to 2,400 pounds of carbon dioxide each year just by recycling half of your household waste. By recycling and buying products with recycled content you also save energy, resources and landfill space!
4) Check your tires. Properly inflated tires mean good gas mileage. For each gallon of gas saved, 20 pounds of carbon dioxide are also never produced.
5) Use less hot water. It takes a lot of energy to heat water. Reducing the amount used means big savings in not only your energy bills, but also in carbon dioxide emissions. Using cold water for your wash saves 500 pounds of carbon dioxide a year, and using a low flow showerhead reduces 350 pounds of carbon dioxide. Make the most of your hot water by insulating your tank and keeping the temperature at or below 120.
6) Avoid products with a lot of packaging. Preventing waste from being created in the first place means that there is less energy wasted and fewer resources consumed. When you purchase products with the least amount of packaging, not only do you save money, but you also help the environment! Reducing your garbage by 10% reduces carbon dioxide emissions by 1,200 pounds.
7) Plant a tree. A single tree can absorb one ton of carbon dioxide over its lifetime.
8) Turn off electronic devices when not in use. Simply turning off your TV, VCR, computer and other electronic devices can save each household thousand of pounds of carbon dioxide each year.
How much we can do from the tips above ? I believe its depend, well the awareness of global warming still lack among many people, some aware but not much action taken to prevent, a truth is a truth, we cannot pretend nothing happen about the truth, the truth that affect the world, an inconvenient truth.
