Is there climate change? Of course. Earth's climate has always been in a state of change. Alaska was once a sub-tropical area that became an arctic environment.
Puny man cannot stop or slow this change. One volcano eruption can put tons of greenhouse gases into the environment. Carbon dioxide is a major greenhouse gas produced by every animal that breathes air. It is used by plants and is needed by them to grow and the plants turn this CO2 back into oxygen that we animals breathe in order to live.
If you want to really make a difference, plant trees, disconnect the natural gas and electricity to your house, throw away your vehicle keys and walk everywhere.
