CLIMATE CHANGE

What does the climate mean?

Climate, like weather, describes the state of the atmosphere in terms of factors such as temperature, rainfall, and wind patterns. Whereas the weather describes conditions as measured in hours, days or weeks, the climate is average weather conditions measured over the longer term: months, years or decades.  

What is climate change?

Any process that causes adjustments to a climate system – from a volcanic eruption to a cyclical change in solar activity – could be described as "climate change". Strictly speaking, climate change is a more accurate phrase than global warming, not least because rising temperatures can cause a host of other climatic impacts, such as changes in rainfall patterns.

The Earth goes through changes all the time. How is different from climate change?

It was reported that the temperature increase recorded in the past 100 years was 0.7 degrees Celsius and of that the Earth warmed 0.4 degrees Celsius in the past 30 years. More than half of the temperature increase was from the 1970s onwards.  

Climate change: Does a small temperature rise actually matter?

This sounds like a small change in temperature; but it can trigger the melting of polar caps which cause fresh water to rush into the warm seas. Also, the differences in temperature can trigger changes which can cause typhoons, changes of sea level and wind currents.  

Are humans definitely causing global warming?

Just as the world's most respected scientific bodies have confirmed that world is getting hotter, they have also stated that there is strong evidence that humans cause the warming indirectly. Each year, human activity causes billions of tones of greenhouse gases to be released into the atmosphere. As scientists have known for decades, these gases capture heat that would otherwise escape to space – the equivalent of wrapping the planet in an invisible blanket. [pic]

What about weather patterns, will those change?...
