Global Warming? Are You Kidding?

Talk about the weather, but can anyone really do anything about it?

Global Warming? Are You Kidding?

Postby Yogi » 23 Feb 2010, 14:40

The title of this thread is something we have all been asking ourselves lately. How could the massive snow storms and extended cold spells be an indication of global warming? Well, here is a link to the explanation: is the key: While the rate of warming slowed, the decade ending Dec. 31, 2009 was also the warmest since accurate records began in 1880, according to GISS. And neither the basic chemistry and physics of global warming nor the continuing increase in man-made greenhouse gas emissions has changed.

The article explains how Arctic Oscillations cause the north pole to be warm and the temperate zones to be cold, which is what has been happening lately. However, this is a natural climatic event that has been going on forever. The trend of global warming over the long term is still in place and the greenhouse gasses we put into the atmosphere is not helping.

    Exactly right!

    Global Warming is, by definition, Global in nature. Just because a few locations have unusually cold weather doesn't indicate that "Global Warming" doesn't exist or is over with, and this is what the Global Warming naysayers don't (or refuse to) recognize.

    For the most part, Global Warming is much more measurable by the general temperature of the average temperature of the world's oceans. From one of the links from the page Yogi provided:

    Climatologists have long known that human-produced greenhouse gases have been the dominant drivers of the warming observed on Earth since the start of the Industrial Revolution. But other factors also affect our planet's temperature. Of these, the world's ocean plays a dominant role. Its effects helped nudge global temperatures slightly higher in 2009 and, according to NASA scientists, could well contribute to making 2010 the warmest year on record.

    Covering 71 percent of our planet's surface, the ocean acts as a global thermostat, storing energy from the sun and keeping Earth's temperature changes moderate and climate change gradual. In fact, the ocean can store as much heat in its top three meters (10 feet) as the entire atmosphere does.

    There are many anecdotal evidences of this phenomena; the imminent loss of the coral reefs near Australia, the loss of Arctic and Antarctic ice mass; the loss and massive movement of various glaciers; anyone who does not recognize this is sadly misinformed or in denial. There are so many articles on retreat of the glaciers in the world. The Jakobshavn Glacier in Greenland is said to be flowing faster these days:

    According to GPS measurements, this glacier is presently flowing as fast as 113 feet per day, making it the world’s fastest-flowing glacier. As its leading edge reaches the Arctic Ocean, more than 20 million tons of icebergs calve off from it each day. This addition of fresh water to the sea—the equivalent of 12 trillion gallons each year—contributes to rising sea level. In fact, this glacier alone is responsible for 4 percent of the global sea-level rise we have seen in recent times.

    There is more information on both this site and the links. Human contribution to the levels of this phenomenon is, of course, subject to debate, but the contribution is there. Anyone denying this is in denial; whether consciously or not. Whether it is reversible, or even controllable, is also up for debate. But any step to control it needs to be taken, no matter how trivial the effect. It may already be too late, but those steps may lessen the impact.
