North Pole may be ice-free for the first time

WASHINGTON - There’s a 50-50 chance that the North Pole will be ice-free this summer, which would be a first in recorded history, a leading ice scientist says.
The weather and ocean conditions in the next couple of weeks will determine how much of the sea ice will melt, and early signs are not good, said Mark Serreze. He’s a senior researcher at the National Snow and Ice Data Center and the University of Colorado in Boulder, Colo.
The chances for a total meltdown at the pole are higher than ever because the layer of ice coating the sea is thinner than ever, he said.
News from around the world are alarming these days especially with regards to the most vigorously debated topic on Earth, the issue of climate change or the so called "Global Warming"
It has been the center of research of most countries and the development of technology to fight it is their utmost concern.
Antarctic ice shelf collapses due to global warming. According to Eugene Domack, professor of geosciences at Hamilton College that the break-up of the ice shelf was caused by a combination of long-term thinning (by a few tens of meters) over thousands of years and short term (multi-decadal) cumulative increases in surface air temperature that have exceeded the natural variation of regional climate during the Holocene period (the last 10,000 years since the end of the last Ice Age).

Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events. reports had found out that human activities have been increasing the concentration of "greenhouse gases" in the atmosphere.
We can only combat global warming if we act now. The very same human ability and industrial capacity that created the problem can solve it.
- Turn off lights when they are not in use. Although the light bulb itself does not emit gases, the power plants that are powering it do.
- Whenever possible, use a fan instead of air conditioning.
- Keep a car tuned up. When it is running properly, it emits fewer harmful gases.
- Walk or ride a bike when it's possible.
- Recycle. Un-recycled garbage ends up in a landfill, which produces methane. In addition, recycled goods require less energy to produce than products made from scratch.
- Plant trees and other plant life whenever possible. Plants take carbon dioxide out of the air and release oxygen.
- Eat less or no beef, as beef production is a large source of greenhouse gases (methane,) as well as a large cause of deforestation.
- Don't burn garbage. This releases carbon dioxide and hydrocarbons into the atmosphere.
- Whenever possible eat food cold. Heating things up wastes more energy than almost everything else.
- Improvise whenever possible; it is better than buying a tool you only use once.
- Don't buy more than one bottle of water in places where the water from the tap cannot be drunk. Instead, buy one bottle, and then boil water, let it cool (but not in the refrigerator) and use the original plastic bottle for your portable water supply. If your tap water is drinkable out of the tap, use this water instead of bottled water.
How come, people sometimes fail
to appreciate nature's existence
not until it's gone.
Not until we lose sight of any significant part of our lives.
That we realized, we have only one
shelter to live in.
