Understanding climate change

Climate change and global warming has become an issue. This section is focussed on climate change and the related issues. The Focus is also on the main terms and definitions used in the discussion about climate change and global warming. Its a worldwide fact now that the earth’s climate is changing. Global warming is a reality now. Global temperatures are rising more quickly than they have done for the last 10,000 years. The decade of 1990s was the warmest in history, and 1998 was the hottest year. The earth’s average temperature has warmed between 0.3 and 0.6 degrees Celsius in the last 100 years. In future, it may rise by two degrees in the next 100 years, if we go on producing greenhouse gases at the present rate. The Sea level has risen by between 10-25 centimetres in 100 years, as polar ice caps have melted. They are projected to rise another 50 centimetres by 2100.

For a better understanding, emphasis has to be given on the relation between global warming and climate change. An important phenomena which acts as the bridge between these two occurings is the climate system. Similarly, greenhouse effect is yet another critical phenomena which is influencing the global temperature and the weather patterns. The impact of global warming is already visible and it is deterioting very quickly. Recurrent floods, droughts, landslides are looking imminent because of global warming. Along with the flora and fauna, human race is going to face a lot many difficulties because of these changes. The knowledge and awareness about global warming is limited to certain sections which is not helpful in such a circumstance. Gaining knowledge and awareness about global warming and climate change is the first step towards tackling climate change.
