More Evidence Piles Up for Global Warming

More Evidence Piles Up for Global Warming

When raising awareness of climate change, especially among those who are hesitant to believe that climate change is really occurring, it's important to include real evidence of global warming in your discussions. Sadly, the evidence supporting global warming just keeps piling up, with the most recent studies pinpointing exactly where all of the excess heat is going.

The Earth's temperature is increasing, and has been for years. Proof of unabated planetary warming has been accumulating rapidly, and a recent study is showing exactly what parts of the earth have been absorbing the excess heat energy. The Southern Ocean, just outside of the tropics, is the area where most of the heat tends to become trapped in the sea. These results go to show that though ocean surface temperatures appear to have stopped increasing for the time being, global warming is not pausing -- the heat is simply being funneled into specific regions. Researchers are careful to point out that it is overall heat gain, and not ocean surface temperature change, that more accurately reflects the warming of the earth's climate.

The results of this study reveal a key issue that should be addressed when discussing global warming. Even if surface temperatures of the ocean don't increase over a period of time that does not mean global warming is slowing down. It probably just means that the heat is going somewhere else -- such as deep into the ocean, as it seems to be in this case. The heat gain experienced in the oceans over the past eight years is the equivalent to that which would be experienced if 2 trillion 100-watt light bulbs were immersed in the ocean and continually lit. On average, at depths between 500 and 2,000 meters below the ocean surface, the temperature has been increasing about 0.005 degrees C per year.

Global warming is not slowing down, making raising awareness of climate change just as important as ever. Encourage your friends to make eco-friendly changes in their lifestyles, such as switching to the biodegradable credit card from Sustain:Green.
