Fact Check: No, global warming hasn’t ‘paused’ in the past eight years
A decade ago, many people in the climate community clearly defined “pause“As global surface temperatures rise. So many studies have been published on the so-called “disruption” scientists jokethat the journal Nature Climate Change should be renamed Nature Hiatus.
However, after a decade of slower-than-average warming, the rapid temperature rise returned in 2015-16, and global temperatures have since remained relatively warm. The past eight years have been the eight warmest since records began in the mid-1800s.
While the discontinuity debate has produced a lot of useful research on short-term temperature change, it is now clear that it is only a small variation on the ever-increasing trend of temperatures.
But nearly a decade later, talk of a “pause” has resurfaced among climate skeptics, with columnist Melanie Phillips stated in the Times this week that, “contrary to the dogma that an increase in carbon dioxide cannot warm the atmosphere, global temperatures have been astonishingly flat for more than seven years even as CO2 levels rise.” up”.
This lie seems to originate from a blog post by longtime climate skeptic Christopher Moncktonwhich states that there has been no trend in global temperatures over the past eight years.
In a rebuttal letter to Times, Professor Richard Betts – head of climate impact research at Met Office Hadley Center and University of Exeter – indicates that “it is entirely predictable that there will be exceptionally high temperature peaks followed by a few less hot years before the next new record year”.
In fact, the past eight years have warmed unusually – even warmer than expected due to long-term rates of temperature rise – with global temperatures exceeding 1.2 degrees Celsius above historical levels. pre-industrial period. Temperature records are provided with short-term periods of slower or faster warming than average, due to natural variability coupled with anthropogenic warming of CO2 and greenhouse gases other.
There is no evidence that the past eight years have been unusual in any way, and the hype surrounding – and the obvious ending – the preceding “pause” should provide a cautionary tale about the acting. over-explain the variation from year to year today.

Greenhouse gases released by humans trap more heat in the atmosphere. While some of this heat warms the Earth’s surface, much of it – about 93% – go into the ocean. Only 1% or so accumulates in the atmosphere and the rest ends up warming the soil and melting the ice.
…
Most years set a new record for the ocean’s heat content, reflecting the continued retention of heat by greenhouse gases in the atmosphere. The figure below shows the estimated annual OHC from 1950 to present for both the upper 700m (light blue) and 700m-2000m (dark blue) depths of the ocean.

Lord Moncton apparently stirred up the hive by publishing a number of articles on the growing pause, like This article is from three weeks ago.
His article about the last 6 years is interesting because where is warming? Shouldn’t there be a hockey stick or something? Oh yes, it is thought to have disappeared into the ocean depths.
In the past 172 years, since 1850, the temperature has risen a little. Except for the period from the 1940s to the 1970s, when global temperature drops has enabled climate scientists like Stephen Schneider suggest we should use nuclear reactor to melt polar ice, to prevent the ice age. Schneider later insisted he made a mistake and went on to become a global warming activist.
But that scene didn’t stop in 1850.
Looking ahead to 1850, there have been notable periods of warmth over the past few thousand years, such as medieval warm period, Roman Warm Period and Minoan’s Warm Periodlooks suspiciously like our modern warm era, except back then people didn’t drive cars.
Going back further, 9000-5000 years ago, in Holocene Optimum, sea level is about 2m higher than todayso it was probably quite warm back then.
20,000 years ago, much of the world is covered by giant ice sheets.
Three million years ago, the world was very warm, Antarctica was almost ice-free – until the beginning Quaternary Glacier, which we are still suffering to this day. To put the Quaternary ice age into context, the Quaternary is one of five comparable major cold periods that have been identified in the last two billion years.
55 million years ago was Palaeocenee – Eocene thermal maximuman extremely warm period of such abundance Our primate ancestors spread all over the world.
When you have a fuller view of the background, instead of the 172 years / 0.0000086% limit of climate history Carbon Brief seems to want you to focus on, there is nothing unusually warm about global temperatures. nowadays. Even as global warming continues, if those tiny primate ancestors with walnut-sized brains could thrive in the Palaeocene – the Eocene heat maximumI’m pretty sure we can figure out how to deal with a fraction of the warming they enjoy.
