What is Climate Change?
Climate change refers to the long-term changes in global temperatures. Climate has changed throughout Earth's long history, but this time it's different. Human activity is causing worldwide temperatures to rise higher and faster than any time we know of in the past.
what cause climate change?
There are two main causes responsible for climate changes. One is a result of natural occurrences, and the other is man-created.
Climate changes do not usually take place immediately after the occurrence of the contributing causes. This is because the earth’s climate system is very large, and it moves slowly and has time-lags in its reaction to the contributing causes.
For example, a year of dry conditions may do no more than shrink rivers and lakes slightly or cause plains to dry marginally. However, in the next year, there may be less rainfall, possibly leading to a drier following year.
The effect of climate change
Climate change affects all regions around the world. Polar ice shields are melting and the sea is rising. In some regions extreme weather events and rainfall are becoming more common while others are experiencing more extreme heat waves and droughts.
Southern and central Europe are seeing more frequent heat waves, forest fires and droughts.
The Mediterranean area is becoming drier, making it even more vulnerable to drought and wildfires.
Northern Europe is getting significantly wetter, and winter floods could become common.
Many poor developing countries are among the most affected. People living there often depend heavily on their natural environment and they have the least resources to cope with the changing climate.
How to stop climate change?
--Be energy efficient
Such as change light bulbs to compact fluorescents or LEDs. Unplug computers, TVs and other electronics when not in use. Wash clothes in cold or warm (not hot) water.
Buy organic and locally grown foods. Avoid processed items. Grow some of your own food. And eat low on the food chain — at least one meat-free meal a day — since 18 per cent of greenhouse gas emissions come from meat and dairy production.
--Green your commute
Transportation causes about 25 per cent of Canada's greenhouse gas emissions, so walk, cycle or take transit whenever you can. You'll save money and get into better shape!
