Global warming causes effects on both North and South poles

Global warming suddenly seems to have dropped off the radar. Just a year back, there seemed to be a concerted global action to try and counter the effects of the effects of global warming – you remember , right ? News of polar ice caps melting, heating of the earth’s temperature, inundation of the low lying countries and lower lying coastal regions, massive variations of temperature, etc. But, the contraction of the global economy, the recession in the US, slow down in other countries, collapse of the global stock markets, etc, all have totally removed the conversations of global warming. It is like global warming had suddenly vanished.
However, just not thinking about the problem does not make it go away. There has been suggestions from some quarters that because of the slowdown of economic activity, it is possible that global warming is no longer the big problem that it was projected to be. After all, with economies in slow down, how can there be the problems with emissions, etc. However, this argument is hogwash. A slow down does not mean that emissions into the atmosphere have stopped; we are still sending more emissions into the atmosphere than it can take. In fact, with strained economic conditions, the capacity to make investments for reducing emissions will become more difficult.

Here is an update on the effects of the emissions on the health of the polar regions:

An international team says it has proven humans are driving up temperatures in both the Arctic and Antarctic. The team, led by Environment Canada climatologist Nathan Gillett, says greenhouse gases pumped into the atmosphere by cars, factories and human activities are a key factor fuelling the change. “Our results demonstrate that human activities have already caused significant warming in both polar regions, with likely impacts on polar biology, indigenous communities, ice-sheet mass balance and global sea level,” the researchers reported Thursday in the journal Nature Geoscience.
The change underway, particularly in the Antarctic, has been one of the most contentious issues in the global warming debate. Some parts of the icy continent, such as the South Pole, are cooling, prompting skeptics to say global warming theories and models are wrong. Gillett and his colleagues say the variations seen on the ground are “consistent” with the theories and models, and do not rule out human impacts on the climate system. “It’s true trends are mixed in Antarctic and we see that in our study,” Gillett told a media briefing.

The polar ice caps along with Greenland hold huge capacities of water in the form of ice sheets; melting of even a portion of these ice sheets will cause huge turmoil in the water level of the world’s seas and oceans. This is a risk that humanity can take only at great peril, and something that we need to avoid at all costs.
