“We conclude that there has been no reduction in the global warming trend of 0.15-0.20°C/decade (~ .3 F/decade) that began in the late 1970s.”
Hansen and the other authors warn that relying on short-term weather cues is not only misleading, but dangerous:
“Given our conclusion that global warming is continuing unabated, and that this conclusion differs from some popular conceptions, we discuss reasons for such perceptions including the influence of short-term weather and climate fluctuations.”
Big news today. Climatologists learn to distinguish between a positive and negative slope.
A new study demonstrates why global surface temperatures defied a decades-long trend and didn’t continue to rise between 1998 and 2008
