Sentences with phrase «showing flat temperatures»

Earlier this year, a paper by Michael Mann - for years a leading light in the IPCC, and the author of the infamous «hockey stick graph» showing flat temperatures for 2,000 years until the recent dizzying increase - made an extraordinary admission: that, as his critics had always claimed, there had indeed been a» medieval warm period» around 1000 AD, when the world may well have been hotter than it is now.

When skeptics used the raw, «unadjusted» numbers, they got Figure 8, which shows a flat temperature trend:

Linear trends are appropriate for the time period after 1990 where the data are described well by a linear trend plus interannual noise (that's why we show a linear trend for the satellite sea level in our paper), but they don't capture the longer - term climate evolution very well, e.g. the nearly flat temperatures up to 1980.

Truncating down to 1950 has yet another benefit: it shows that if we ignore the temperature data beyond 1970 (since we're using 1950 - 1970 temperature data to avoid end effects) and find the best fit using only HadCRUT3 up to 1970, we predict the next four decades of temperature remarkably well, even predicting the relatively flat temperature for 2000 - 2010, which the model shows is entirely attributable to SOL and has nothing to do with a cessation of long - term global warming.

I ask because the new updated chart shows they can argue models are consistent with observations, even if temperatures are flat all the way out to 2035.

The Marcott study is one that raised a stink because it was an attempt to create yet another «hockey stick» graph in which all of human history — this time, going back 11,000 years — shows a flat line of global temperatures, with only recent decades showing an alarming upward trend like the blade of a hockey stick.

«Actually, with the exception of 1998 — a «blip» year when temperatures spiked because of a strong «El Nino» effect (the cyclical warming of the southern Pacific that affects weather around the world)-- the data on the Met Office's and CRU's own websites show that global temperatures have been flat, not for ten, but for the past 15 years.

In scientific parlance, this is called «cherry picking», and explains how Whitehouse can assert that «since [1998] the global temperature has been flat» — although he is even wrong on this point of fact, because as the graph above shows, 2005 was warmer.

The fact that the raw data in long term rural reporting stations always show a long term flat temperature (or a decline) while the interpolated anomaly shows warming is going to tend to inform me that people are fudging the records.

Had Briffa and Osborn shown the decline, instead of Severinghaus wondering about the «flat» response, he would presumably have been asking about the sharp divergence between the Briffa reconstruction (based on a very large population of sites identified ex ante as temperature limited) and the Mann reconstruction (based on bristlecones).
