Global Warming

What is Global Warming?

Global warming is the increase in the average measured temperature of the Earth's near-surface air and oceans since the mid-twentieth century, and its projected continuation.

It was 2 years ago that I first visited States. Both trips were made in summer but I can feel the effects of global warming during the second trip.

1st trip, weather was warm but the wind was cooling, no perspiration.

2nd trip, weather was warmer and i would perspire.

See below for extracted reports

Arctic Ocean sea ice – one of the most visible indicators for global warming – may be headed for another record-breaking summer decline.

The ice’s seasonal shrinkage in 2007 smashed records, reaching a September minimum of 2.6 million square miles – some 23 percent smaller than the previous record, set in 2005. If it sets another record this year, it would mark the fifth season of record declines since 1998.

A US-based team has told a conference in California that the northern polar waters could be ice-free in summer by 2013.

Satellite images taken since 1979 show that ocean ice cover in the region has declined steadily, with an estimated 38,000 square miles now being lost every year. Computer models predict sea ice could vanish from the Arctic ocean completely as early as 2040.

The loss of Arctic sea ice will have a dramatic impact on polar bears and other species that hunt among the ice floes, but it will also trigger erratic shifts in climate that will be felt around the world, scientists believe. The bitter Arctic fronts that blow across Colorado and the western United States may warm and bring less snow, while winter storm tracks across parts of Europe are expected to intensify and unleash torrential downpours. - extracted

I watched documentaries on global warming. 1 degree warmer is disastrous. There are findings and reports on the actual figures but let me put it in simple words.

Temperature rises, icebergs melted, water level increases, countries will be affected by hurricanes, flood or earthquakes etc..

I cannot imagine what will happen in the next 10 years...
