There is much doubt, confusion and belief among the British who cling to arguments not supported by science. Sound familiar? Here's the result: most Brits do NOT think human acitivity is causing global warming. And that coincides with the very informal results of our own poll among readers of this blog. Most answering our poll question do NOT believe global warming is something we humans need to do something about. We've been disagreeing about global warming (greenhouse effect) for more than twenty years and that's not about to change either in the US or the UK.
