Because in the past the poster called Bags has systematically tried to rubbish everything I've had to say (about climate change). That is why I gave up posting on Gransnet. I just happened to pop in and have a look today. The thing is Climate Change is too important to let denials go by without challenging them. Things are getting worse; scientists now think the tipping points are nearer than originally thought. Governments are not doing what they should. For instance our government has not taken account of methane which is a far worse greenhouse gas than CO2. And fracking could cause huge quantities to belch out; and melting permafrost will release huge amounts of methane too.
I have grandchildren, it worries me sick about what sort of future they will have. I have to protest, that is all I can do. I am not an expert but on the other hand I do read a lot of scientific stuff and I do have several friends who are scientists; I've been involved in environmental stuff for over forty years so I'm not talking through my hat. Some of the stuff posted on gransnet is by scientists who are sponsored (paid, that is!) by vested interests ie the fossil fuel industries. This just makes me sick.....
Sometimes people try to make out CO2 is harmless. Well, water vapour (from planes) is a greenhouse gas. Obviously it depends where it is as to whether or not it does harm. Same goes for CO2
