Further evidence unnecessary, but keep it in our armoury

The US National Academy of Sciences.

Further evidence that humans, that’s you and me, are causing our climate to change seems unnecessary.

However, the message that business as usual is the root of the trouble has as yet not been understood or accepted by the world’s “responsible men”.

Confronted by a doubter who has economic, political and social clout, and sprouts sensible sounding rhetoric, can be a challenge you might night rather wade into.

However, a report entitled: “Climate change: Evidence and causes” from the Royal Society and the US National Academy of Sciences gives you an invaluable armoury of information.

It provides relatively simple answers to most objections raised by doubters and then, if you want more, further detail follows.

Recent personal experience shows that many people, frequently in positions of significant influence, and who have the capacity to change our behaviours, still question the reality that is climate change.
