Do you understand the difference between US data and global data?
Which would you say are more relevant in assessing climate change?
Also - are blogs as reliable as scientific organisations, would you say?
Did you read the OP subject line?
Where do you presume the most accurate temperature data is taken?
Did you even notice I made no statement on whether or not the climate was changing?
Being a child of the 60s and 70s I once was fooled by data that said this or that was GOING to effect me and the world and that never happened. So instead of listening to the same gloom and doom that never happens I look out the window and see another sunny day. I think a little warmer would be a good thing, why do you apparently think colder is a good thing?
