Showing posts with the label no warming

The non-existant pause in global temperatures

Regular readers of this blog will know that I am skeptical of claims that global warming in atmospheric temperatures have paused since 1998, having written several posts questioning the existence of such a pause.  In this edition, I'll run down the main evidence that, in my opinion, show that the pause is a figment of the denialsphere's imagination.

The "no warming" claim rises from the dead yet again.

Like a movie vampire, this one keeps coming back no matter how many stakes are driven through its heart.  I've covered this one ( here , here , and here ).  Bluntly: There is absolutely no evidence that global warming has stopped.  For global warming to stop, the Earth's energy balance must be either zero or negative.  The most recent estimates for the energy imbalance are generally between +0.5 W/m 2 and +1.0 W/m 2 .  The only way the Earth is not going to warm while it is gaining energy is if the laws of thermodynamics magically do not apply.  If the Earth is gaining energy, some part of it, somewhere, must be getting warmer.  The heat must go into either melting ice, warming the oceans, warming the land, or warming the atmosphere (or some combination thereof).

Monckton, RSS, and no warming since September 1996

While browsing a climate change article on Huffington Post, I noticed a global warming denier using a Watts Up With That post by Lord Monckton as "evidence" that global temperatures haven't changed since September 1996.  In it, Monckton uses least squares regression to show that satellite data from RSS is flat (trend: -0.0001394ÂșC per year) between September 1996 and January 2014.
