Bangladesh is one of the world most densely populated country and one of the most susceptible countries to flood disasters. It also has one of the three most powerful rivers passing though it Ganges, Meghna and Brahmaputra. About one half of the land area in Bangladesh is at an elevation of less than 8 meters above sea level.  Up to 30% of the country has been covered with flood waters.  In 1991 more 200,000 deaths resulted from flooding and associated tropical cyclones.

The Arctic Ice Cap

The Arctic ice cap shrank so much that waves briefly lapped along two long-imagined Arctic shipping routes, the Northwest Passage over Canada and the Northern Sea Route over Russia. Complicating the picture, the striking Arctic change was as much a result of ice moving as melting.

 

 

 

 

 

 

 

 

 

A host of Arctic scientists say it is too soon to know if the global greenhouse effect has already tipped the system to a condition in which sea ice in summers will be routinely limited to a few clotted passageways in northern Canada.

 

 

 

 

 

 

 

 

 

As we move along with those pictures we can see the Arctic ice caps are melting but very fast. In 2005 the scenario was much worst.

 

 

 

 

 

 

 

 

 

All those pictures were taken on September 16^th each year, which is right after the summer. Summer 2007 shows a record breaking loss of arctic sea ice. Experts attribute the changes to the interaction of wid. Weather, ice drift, ocean current and greenhouse gases.

Global Warming

Global Warming is an environmental issue that is continuing to harm our planet. The definition of Global Warming is “the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-20th century and its projected continuation” (Wikipedia). Therefore, if in the winter snow melts faster than it snows then there has to be something wrong with Earth because average temperature for many years that change one year? The answer is Global Warming. All of sudden icebergs started to melt in Antarctica, North Pole, Greenland and Alaska because of Global Warming. “If we could see with our own eyes how fast the icebergs are malting and hear the sound cracking and  crashing of icebergs one into another, we would realize better, what we are doing to our own planet” (An inconvenient truth).

“It is now clear that we face a deepening global climate crisis that requires us to act boldly, quickly and wisely” said Al Gore.
