Who writes the headlines for editorials? The top editorial in the Oct. 12 PG was tricky. The headline "As the World Warms" was flat out wrong. Global temperatures haven't risen since 1998. However, the editorial dances around that issue by implying that global temperatures have continued to rise.
Proponents for humans causing global warming are nearing a panic mode. Many scientists, for different reasons, expect global temperatures to decline in the immediate future. Will that happen? Nobody knows. Global warming deniers don't know. Global warming proponents don't know and computer models don't know.
There's a tipping point, all right. If global temperatures do decline in the next couple of years, a lot of stuff will come tumbling down.
