1 CLIMATE CHANGE
I have decided to talk about climate change for my first topic – as the weather at the moment is changing. There has been a hurricane overseas and we are getting some of it so the winds are very strong they say it can be up to 70mph some airports have been shut. Windy rainy days but still very humid. Sunny and windy days but cold.
Climate measures the average pattern of variation in temperature, humidity, atmospheric pressure, wind, precipitation. Climate is different from weather, in that weather only describes the short-term conditions of these variables in a given region.
Climate change means the average temperature across the world either increases or decreases. It happens naturally as the earth goes through cycles, such as an ice age
Global warming is the rise in temperature of the earth's atmosphere. It's said that by the time a baby born today is 80 years old, the world will be 6 and a half degrees warmer than it is now.
Is global warming bad?
The earth is naturally warmed by rays (or radiation) from the sun which pass through the earth's atmosphere and are reflected back out to space again. The atmosphere's made up of layers of gases, some of which are called 'greenhouse gases'. They're mostly natural and make up a kind of thermal blanket over the earth. This lets some of the rays back out of the atmosphere, keeping the earth at the right temperature for animals, plants and humans to survive. So some global warming is good. But if extra greenhouse gases are made, the thermal blanket gets thicker and too much heat is kept in the earth's atmosphere. That's when global warming's bad.
The government is working at home and abroad to adapt to the effects of climate change and reduce greenhouse gas emissions by investing in low-carbon energy sources, improving fuel standards in cars and increasing energy efficiency wherever possible.
The increase in ocean temperatures, drier areas are becoming even drier and wetter...
