Climate Change. What is Climate?. The long-term average of a region’s weather: Average rainfall Average hours of sunshine Average temperature. Q. Is there a difference between Climate and Weather?. Weather describes whatever is happening outdoors in a given place at a given time.
The long-term average of a region’s weather:
Q. Is there a difference between Climate and Weather?
Climate change represents a change in these long-term weather patterns;
Climate change has occurred naturally over millions and millions of years.
When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.
To understand human-induced climate change it is helpful to look first at the ‘greenhouse effect’.
Q. What do you think is meant by the ‘Greenhouse effect’?
0n Earth, the atmospheric gases allow sunshine to pass through but absorb heat that is radiated (bounced) back from the warmed surface of the Earth
Q. What are the gasses we associate with global warming?
If the greenhouse effect becomes stronger, it could make the Earth warmer than usual.
Sea levels around the world could rise.
Cities on coasts would be liable toflooding.
Temperate places that now receive frequent
rain and snowfall might becomehotter and
drier, leading to more drought.
Frequent periods of drought would make
it hard to raise crops for food, leading to famine.
Forest fires could occur more often.
Plants and animals unable to take the heatmay go extinct, and be replaced by heattolerant species.
Hurricanes, tornadoes and other stormscaused bychanges in heat and waterevaporation might occurmore frequentlyand be more intense.
