global warming Archives Universe Today. After being confined to the media and internet blogs for some time, this contrarian framing eventually found entry into the scientific literature 3,4, which is now replete with articles that address a presumed recent “pause” or “hiatus” in global warming 5. The “hiatus” also featured as an accepted fact in the latest assessment, 4. The recent hiatus in global warming. A marked diminishment in the strong rate of global warming evident in the 1980s and 90s was identified in the recent period 1998–2014, and has been the subject of much debate in the climate community in recent years..
A global warming hiatus, also sometimes referred to as a global warming pause or a global warming slowdown, is a period of relatively little change in globally averaged surface temperatures. In the current episode of global warming many such periods appear in the surface temperature record, along with robust evidence of the long term warming trend..

After being confined to the media and internet blogs for some time, this contrarian framing eventually found entry into the scientific literature 3,4, which is now replete with articles that address a presumed recent “pause” or “hiatus” in global warming 5. The “hiatus” also featured as an accepted fact in the latest assessment by Trenberth and Fasullo (2013) entitled An apparent hiatus in global warming? The authors favour вЂglobal heating’ as a вЂmore scientifically accurate’ headline description of human influence on the Earth’s climate, allowing for the paradox of a planet which is heating and yet displaying virtually no atmospheric warming at the surface because of heat uptake by the deep ocean: The authors ask: “Has global warming …
ing to understand the global climate system, other im-portant aspects of the “hiatus” related to observational biases in global surface temperature data have not received similar attention. In particular, residual data biases in the modern era could well have muted recent warming, and as stated by IPCC, the trend period itself was short and Global Warming and the Next One J. Isaac Miller 1 and Kyungsik Nam 1 1 University of Missouri Correspondence: J. Isaac Miller (millerjisaac@missouri.edu) Abstract. Much has been written about the so-called hiatus or pause in global warming, also known as the stasis period, the start of which is typically dated to 1998. HadCRUT4 global mean
shown that global warming is human induced, natural climate variability still plays a significant role and likely can still overshadow the global warming trend. For instance, the hiatus of global warming (the leveling off of the global mean temperature increase) over the past 15 years is likely to be due to natu-ral climate variability 05-12-2013 · Global warming first became evident beyond the bounds of natural variability in the 1970s, but increases in global mean surface temperatures have stalled in the 2000s. Increases in atmospheric greenhouse gases, notably carbon dioxide, create an energy imbalance at the top‐of‐atmosphere (TOA) even as the planet warms to adjust to this imbalance, which is estimated to be 0.5–1 W m −2 over the …
the warming period, with 72% of the simulated trends positive, to 20.077 0.734PgCyr during the warming hiatus, with 54% of the simulated trends negative (Fig.1h; P value <0.01; Table1). Therefore, we conclude that the apparent acceleration in net terrestrial C uptake over the warming hiatus is most In the news lately is a genuine scientific debate whether the apparent hiatus may be due to biases in the data. We don't need that genuine scientific debate to finish in order to conclude that it is a misconception to think "'the global warming hiatus' means global warming stopped". Anyone who knows the scientific literature knows that's absurd
