Climate Change
I do beleive that human activity has and is affecting the climate. However I have to agree with the Federal Opposition from the point of view that it is better to wait until after the Copenhagen Conference before deciding on the best course of action. The Federal Government rush to have it passed by the end of the year was nothing more than political grandstanding so that Kevin Rudd/ Penny Wong could go to Copenhagen and tell the world how good they are (not) in getting the first scheme up.
As a young University student in the late 60's we were told of the natural cycles of cooling and warming of the planet and that we were and still are in a natural warming cycle. Evidence of that can be found in thge likes of Glacier Bay Alaska where the extent of the glaciers has been tracked since the mid 18th century and it has retreated a long way over 70 miles or so since that time in a steady progression.
That is not to say that human activity by way of the Industrial Revolution has not contributed to the an acceleration in the warming process. I would venture to say that human activity is a significant harmonic on the natural warming and cooling cycles the planet goes through.
In my lifetime I have noticed a significant change in the climate particularly since the acceleration in industrialisation in developing countries like India and China in the last 20 years. That is not to say that India and China are to blame, we are all to blame as we live more and more opulent lifestyles.
The highly developed countries laid the foundations for climate change in the last century with rampant industrial and economic growth based upon the use of fossil fuels for energy to support that growth.
We all have to take a step back in the industrialised world and take steps to mitigate our use of energy and processed resources.
However I am not sure that an Emissions Trading Scheme based upon taxation only is necessarily the best option.
Why is the ice melting in Russia. I think this question has to be addressed.
Arctic sea ice melting, which scientists have linked to global warming, may be a boon for the shipping industry. As the sea ice continues to melt a shipping passage to Russia’s north is becoming more navigable, and now two German ships are close to completing the first trip from Asia to Europe via the Arctic shortcut. However, walruses that live in the Arctic could care less, since their sea ice habitat is rapidly disappearing.
Thousands of walruses are congregating on Alaska’s northwest coast, a sign that their Arctic sea ice environment has been altered by climate change. Chad Jay, a U.S. Geological Survey walrus researcher, said Wednesday that about 3,500 walruses were near Icy Cape on the Chukchi Sea, some 140 miles southwest of Barrow [AP]. Walruses wear themselves out diving for clams, and need to rest on the sea ice between meals. Since the sea ice is disappearing, they are turning to the shore for a break. Federal managers and researchers worry that so many walruses in one location could lead to a deadly stampede or could drive off prey. Highlighting the animals’ peril, the Obama administration is considering adding walruses to the endangered species list.
Does anyone know if the arctic north west passage has been opened to shipping before.
The melt is good news for shippers looking to haul cargo between Asia and the West since it’s thousands of miles shorter than southern routes like the Suez Canal. The two German ships are on track to be the first to travel the entire route, called the northeast passage. The ships started their voyage in South Korea in late July and will begin the last leg of the trip this week, leaving a Siberian port for Rotterdam in the Netherlands carrying 3,500 tons of construction materials…. [The ships were] accompanied for most of the trip so far by one or two Russian nuclear icebreakers as a precaution, although they encountered only scattered small floes. At the most perilous leg of the journey, the passage around the northernmost tip of Siberia, the Vilkitsky Strait, ice covered about half the sea. [The New York Times].
