The unwarming world

The world has not warmed since 2001.


Goldilocks graphs: not too close, not too far

Have you noticed, the scaremongers are being boxed into reusing the same graph over and over. We sceptics are not afraid of any graph, but alarmists just don’t want to look from too close or too far away…

When skeptics debunk a graph we show the graph we debunk. Not so the carbon-is-a-crisis crowd. The latest trend in graphology-PR is to debunk sceptics graphs by ignoring the graph itself and putting up an entirely different graph.


Ocean temperatures: the new bluff in alarmism

There are 2014 updates on this topic:

Ocean temperatures – Is that warming statistically significant? IPCC in denial. “Just-so” excuses use ocean heat to hide their failure.

There has been a change in direction by the alarmists, as shown by their new “Synthesis Report.” The independent scientists noticed it during the Wong-Fielding meeting.

The alarmists have abandoned air temperatures as a measure of global temperature, because the air temperature graphs are just too hard to argue with (like the second figure below, from the Skeptics Handbook). Instead they’ve switched to ocean temperatures, which they often disguise as ocean heat content (a huge number like 15×10²² Joules sounds much more scary than the warming it implies of 0.003° C/year).

All three pages of the Synthesis Report that deal with ‘evidence’ are about factors or trends that tell us nothing about whether or not the warming is due to carbon emissions. If God put the galaxy in a toaster, sea levels would rise, ocean heat content would increase, and ice would melt.

Notice how the graph above from the Synthesis Report that came out this month doesn’t include the last six years of data? Carrier pigeons from the remote worldwide [...]
