- Hello Mary! How are you? I have not seen you for ages!
- Hello Kate. I am fine, thank you. I am not too good because of this weather.
- Yes, you are rifgt. We never used to have weather like we have these days.
- No, I know. There doesn't seem to be any satbility any more. It's cold when you expect it to be warm and warm when you expect it to be cold.
- They say it's a lot to do with the greenhouse effect.
- I have heard about that. Doesn't it come from all the carbon gasses we're putting into the atmosphere?
- Not to mention central heating and air conditioning. The gasses stop the sun's heat escaping into space, just like the glass in a greenhouse does.
- So, the heat is trapped in the atmosphere making it hotter and hotter. It may be all for plants, but not for us. I think it is scary.
