I was trying to define what climate change is. In my country it is a real big problem .
Human activities have increased carbon dioxide emissions, driving up temperatures.
Extreme weather and melting polar ice are among the possible effects.
What is climate change?
The Earth's average temperature is about 15C but has been much higher and lower in the past.
There are natural fluctuations in the climate but scientists say temperatures are now rising faster than at many other times.
I have been talking about this aim to my students because they don't have a real image of this problem .
We have to be aware of the concrete problem and try to do something to change before it is too late.
Ash and sulfate aerosols have a cooling effect as they reflect sunlight away from Earth while CO2 causes warming. Mt Etna, Sicily, is one of the most active volcanoes in the world, and may emit 1 million tons of CO2 in a quiet year. ... An eruption of Mt Etna will likely not affect the global climate.14 dic 2016
