We all know that the oceans are absorbing more CO2 and becoming more acidic. There are many well known consequences to this such as the dissolving of pteropod exoskeletons. However, what isn’t so well known is what happens to the distance soundwaves travel.
As the oceans become more acidic, the soundwaves travel a greater distance. This can become a problem for marine animals depending on the ability to communicate for hunting and other functions. Check it out here.
Polar Bears are in trouble. It is easy to see the link between global warming and polar bear extinction. Polar bears hunt on sea ice. Global Warming causes the melting of sea ice. With less sea ice there is less room for the bears to hunt on. Polar bears can only swim for relatively short distances. Some of them drown. Some of them turn to cannibalism. The female bears don’t have enough weight to produce milk so the cubs die. The situation is grim. Something needs to be done. They have finally been listed as threatened (not endangered). What are we waiting for? Two-thirds of Polar Bears may be gone in the next 30-40 years!
Even after watching last night’s vice presidential debate, some people still aren’t convinced that Global Warming is caused by man! In the face of overwhelming evidence, some people still just shrug their shoulders in disbelief. Why are they still denying it? Do they really believe what they say they do? Or are they just afraid of what it will mean to our way of life? Some of the more educated skeptics state that the climate change we are experiencing is a result of the natural cycles of our orbit and the sun’s fluctuating heat output (click here for info on the Milankovitch theory of changing climate).Read more about skeptic’s beliefs here
Since Global Warming is our problem and NOT the sun’s lets try to reduce our carbon footprint.
The below video is from Competitive Enterprise Institute (CEI) and discusses Carbon Dioxide. One more little bit of info. CEI gets funding from Exxon, Texaco, and Ford Motor Company. Keep that in mind while watching the clip!
