Hello Deepthi,
From your question it appears you’re in India. Some time ago a question was asked on here as to how climate change would affect India in the future, rather than copy and paste a long answer here’s a link to it: http://answers.yahoo.com/question/index?...
On a more global scale then pretty much everyone is being, and will be, affected by climate change in one way or another.
For many these changes will be small and they’ll live out their entire lives without really being aware of the effects of climate change.
I’ll give you an example. In 1976 the UK experienced an exceptionally hot year and everyone who lived through it will remember it well. We remember it because it was so unusual. But since 1990 there have been 15 hotter years (based on the HadCET temperature record), we’re so used to them now that this has become the new norm and few people realise that the weather shouldn’t be as warm as it is. In other words, we’re all experiencing global warming without being aware of it.
Some of the headline points of a changing climate are…
? Overall higher temperatures, so far there has been an increase of about 0.85°C globally, it’s likely that there will be a further 2°C to 3°C rise by the end of the century.
? More adverse, unsettled and unpredictable precipitation. Globally the number of floods has increased six-fold since 1950, you’ll be aware that India has recently suffered from several devastating floods. Worldwide the amount of precipitation has increased by 10% as the extra heat in the atmosphere and oceans causes the hydrological cycle to accelerate.
? The disruption to rainfall patterns means that there has been an increase in the number of droughts, the worst hit areas are those that already had arid conditions and unpredictable rains.
? There are now twice as many heatwaves as there used to be and more people are dying from them. Every heatwave that has claimed more than 1,000 lives has occurred since 1980 including the 2003 heatwave that struck Southern India, the same year that 70,000 people died in the European heatwave.
? Water resources are becoming scarcer in some places, particularly those that rely on river-water and glacial melt-water. Millions of people in the foothills of the Himalayas have now lost their water supplies as half the glaciers have melted in recent years.
? Some areas are turning to desert, China has been hardest hit with over a million farmers having had to abandon their farms. Elsewhere, in places such as Siberia, the warmer climate has melted permafrost and opened up some new land for farming, unfortunately most of the thawed ground is peat-bog so it’s not a lot of use.
There are a great many other effects including the threat to species, loss of habitat, crop disruption, rising sea-levels, spread of diseases etc.
Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.
Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
" Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time. "
- Intergovernmental Panel on Climate Change
Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gasses produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.
We can only speculate. Scientists have determined that the mean temperature of the earth has only varied about a degree in the last 150 years, so we really haven't had any climate change affect us.
You might need to either put a tee shirt on or alternatively a thick jumper, it's best if you make this choice shortly after waking up.
EDIT to address lies:
The UK has not had a hotter summer than 1976 in my lifetime, to suggest otherwise is ludicrous,
Hi .........Because all of the natural systems for which we depend are tied into climate,and i you know..... any sustained change in climate can affect many related aspects of where and how people, plants and animals live, such as food production, availability and use of water, and the amount of energy used.
climate change has a negative impect in humans life.this situations is very bad in human Health .........
so pls save environment ,,,,,,,,,,, thanks for
i guess changes of climate is going to head another evolution..surely it will destroy species from earth
catch cough because of cooling wind,
It hasn't in my lifetime.
sometimes you'll need to wear a jacket, sometimes you won't..
plsss explain ........
