Climate of the world is changing.

Climate is changing, carbon dioxide is increasing, and Earth is getting hotter.

Mumbai floods
First it was Bombay floods, then Kosi floods, Punjab floods, Rajasthan floods, Leh floods, Jharkhand drought (all in India). Now it is Paksitan floods, China flash floods and landslides, boiling of Moscow, forest fires in Russia, Bolivia and Portugal, and there are lots more to say and write. Millions affected, thousands died, no ending disaster. Climate of the world is changing. What would you think? Yes its climate change or in other broad definition its global warming.

If we take the case of drought in Jharkhand State of India, it is very unusual. Other than some pockets of the state, Jharkhand never passed through severe droughts. Rainfall was sufficient all around the year. But from last one year rainfall pattern has changed. Farmers are still waiting for the sufficient rainfall. Agriculture scientists are worried. Monsoon Clouds have changed their way from Bay of Bengal.

Scientists feel that carbon dioxide is rising, so temperature is also rising. And they conclude that, all these disasters are the out come of Global Warming and El Nino. To larger extent it’s true. Climate is changing worldwide. Where it is use to rain heavily now passing through droughts.

All the three factors (air temperatures, air pressure and humidity) which affect weather are changing. Temperature is rising so the humidity. Humidity is the amount of moisture that is present in the air. We know that the amount of moisture in the air affects the climate and weather greatly. If there is a lot of moisture in the air, it is likely to rain.

The cloud become bigger and bigger, heavier and heavier. Finally, the water droplets become so heavy, that they fall as heavy to very heavy rain as it happened in Leh and part of Uttrakhand states in India, where hundreds died this year due to cloud brust.

Heating of Arabian Sea has resulted in the disaster floods in Mumbai, now in Rajasthan and Gujrat and in neighbouring country Pakistan.

Heavy rains have also affected Delhi, Mumbai and other metro cities of India. Other than climate change, “Urban heat island effect”, may be the other cause of these heavy showers. Scientists have found that urban areas are 1 to 5.5 degree centigrade hotter than the countryside.

The summer of 2002 saw widespread flooding over much of central and western Europe, from Romania to Russia. The city that was most badly affected and was certainly most in the news was the Czech capital, Prague. In August of that year heavy rainfall from a slow-moving frontal system which also affected much of the rest of Europe. The river Vltava rose ominously, forcing the country’s president to enforce an evacuation of 40,000 people.

Scientists discovered that North America, Europe, Asia and Australia had the highest rate of warming during the 20th century. These places experienced temperature rises of between 0.5 and 0.6 degree centigrade from 1950 to 1999. Industrial activity coupled with deforestation in these parts of the world is high. Oil refineries and factories that burn fossil fuels for making electricity produce air pollutants, such as sulfur dioxide and carbon dioxide. As carbon dioxide is greenhouse gas, it traps heat and warms the earth’s surface.

Climate is changing, carbon dioxide is increasing, and Earth is getting hotter. We are under the threat of worst changes of nature. Scientists have found that the Earth’s temperature increased up to 0.6 degree centigrade during the 20th century. They believe that one of the main causes of this global warming is the increase in green house gases in the atmosphere. They estimate that if the amount of green house gases continues to increase, the earth’s temperature will continue to rise too, perhaps by up to 3.5 degree centigrade over the coming decades.

Flood devastation in Pakistan.

Assistance requested by The International Rescue Committee (IRC).

The worst flooding in Pakistan's history has now affected more than four million people and left at least 1,600 dead, says the UN.

While floods in the north-west began to recede, the vast body of water has been moving down the country into new parts of Punjab and menacing Sindh province.

All wells have been contaminated and water-borne diseases are spreading, officials say.
The region is midway through monsoon season and more rain is forecast.

The number of affected districts in Punjab has reached seven, while 350,000 people have been moved from neighbouring Sindh province, most of which is on high alert, the United Nations said.

In Punjab, known as Pakistan's "breadbasket" for its rich agriculture, more than 1,300 villages have been affected and at least 25,000 homes destroyed, said disaster relief officials in the province.

In the worst-affected areas, small villages have been submerged.

In large tracts of Kot Addu and nearby Layyah, water levels were so high only treetops were visible.

The 2010 Pakistan floods began in July 2010 after record heavy monsoon rains. The Khyber Pakhtunkhwa province of Pakistan was worst affected. At least 1,600 people were killed, thousands were rendered homeless, and more than fourteen million people were affected. Estimates from rescue-service-officials suggest the death-toll may reach 3,000 victims. According to a recent estimate of United Nations, the number of people suffering from these massive floods in Pakistan exceeds 13.8 million, which is more than the combined total of the 2004 Indian Ocean tsunami, the 2005 Kashmir earthquake and the 2010 Haiti earthquake.

The floods were caused by monsoon rains, which were forecast to continue into early August and were described as the worst in this area in the last 80 years. The Pakistan Meteorological Department said that 300 mm (12 inches) of rain fell over a 36-hour period and more was expected. So far as many as 500,000 or more people have been displaced from their homes. Manuel Bessler, head of the UN Office for the Coordination of Humanitarian Affairs, stated that 36 districts were involved, and 550,000 people were affected, although later reports increased the number to as high as a million affected.
Officials have warned that the death-toll could rise as many towns and villages are not accessible and communications have been disrupted. In some areas, the water-level was 5.5 m (18 ft) high and residents were seen on roof-tops waiting for aid to arrive. At least 45 bridges and 3,700 houses were swept away in the floods. The Karakoram Highway, which connects Pakistan with China, was closed after a bridge was destroyed. The ongoing devastating floods in Pakistan will have a severe impact on an already vulnerable population.
Mean while United Nations has criticized the world nations for responding slowly, despite the ferocity and magnitude of disaster. As of 9 August, only $45 million have been committed, which is far less than several recent natural disasters combined.
The International Rescue Committee contacted me to circulate this information through my blog to help Pakistani people in distress.

The International Rescue Committee (IRC), a global leader in humanitarian assistance, is on the ground providing aid to survivors of the flooding. You can read about their emergency response efforts here [link: http://www.theirc.org/news/irc-ground-flood-ravaged-pakistan-situation-desperate-9144].

The IRC has been providing lifesaving aid in Pakistan for 30 years. they are already working in the areas hit hardest by the floods, including Charsadda, Kohat, Lower Dir, Nowshera, Tank, Mardan and Swat. Last year, many of these same areas were affected by fighting between militants and government forces that uprooted millions of people.
The IRC will also focus on providing clean water, sanitation, shelter and essential supplies to those who have fled the rising waters. With their robust network of local staff and partners already on the ground -- and decades of experience responding to emergencies in Pakistan -- the IRC is well-positioned to help families in dire need.
