Climate change: A 'pause' in global warming? Not on this evidence

2015 is likely to follow 2014 and 2010 as the next record hot year

Some have called it the “pause”, others the “hiatus”. Now it seems neither description is accurate, given that the three hottest years on record have all occurred in the last five years and that nine out of the ten hottest years have all been in this century.
Climate sceptics, such as the former Chancellor Lord Lawson and ex-minister Peter Lilley, have repeatedly claimed that global warming has either stopped or slowed down to justify their arguments that action on climate change is premature or unnecessary.
Even the Intergovernmental Panel on Climate Change and the UK Met Office have talked about a “slowdown” or “hiatus” in the rate of increase in global surface temperatures, seemingly over the past decade or so, compared to the end of the last century.
Other researchers, however, are not so sure that the data can be read this way, especially now that 2015 is likely to follow 2014 and 2010 as the next record hot year (while the chances are that 2016 will be among the top three as well, because of a continuing El Nino).

“We really don’t have a pause in global warming. I’ve frankly never really agreed with that,” said dr Jessica Blunden, a climate researcher at the US National Oceanic and Atmospheric Administration (NOAA), which collates records on land and sea temperatures. “We’ve continued to break heat records in the 21st century since 1998 – 2005 was a record warm year, then 2010 was a record and then 2014 was a record and now we’re getting ready to beat that record again. I disagree with the thought that there is a warming hiatus.”
A major review of global temperatures by NOAA earlier this year found that the rate of increase in global surface temperatures over both land and sea has been just as fast at the start of this century as it was at the end of the last.
Its scientists said the “hiatus” is nothing more than an illusion resulting from flaws in the way data was collected, and the fact that 2015 seems destined to break the record again underlined that.

Climate Change Skeptics Lash Out At New Global Warming ‘Hiatus’ Study That Questions Ocean Temperature Measurements

A study published June 4, 2015, refuting the notion that the Earth’s temperature rise has been interrupted since 1998 was lambasted by the usual skeptics and their supporters.  Corey Accardo/NOAA/NMFS/AFSC/NMML/Via Reuters A new climate study was released Thursday that refutes the claim that there’s been a slowdown, or “hiatus” in the rate the Earth is warming, but some conservative-leaning media sites skipped covering the study itself and chose instead to promote the views of the minority of climate change deniers, such as  Christopher Monckton . For example, the Drudge Report, an immensely popular headline aggregator operated by conservative Matthew Drudge, promi...

Global warming could drive world temperatures up 7 degrees by 2100

Another piece of the  global warming  puzzle has been revealed. According to new research published on Jan. 1 in the journal  Nature , increased levels of carbon dioxide in the atmosphere will reduce the number of clouds that form. This, in turn, will cause temperatures to rise much higher than previous climate-change models have predicted. According to this new research, global temperatures could rise 4 degrees Celsius or 7.2 degrees Fahrenheit by the year 2100, and twice that by 2200. Lead researcher Steven Sherwood at the Climate Change Research Center at Australia's University of New South Wales, told  The Guardian  that this level of climate change would be "catastrophic rather than simply dangerous. For example, it would make life difficult, if not impossible, in much of the tropics, and would guarantee the eventual melting of the Greenland ice sheet and some of the Antarctic ice sheet."   In a  news release , Sherwood said this new...

Why Is Critical Technology to Stop Global Warming Stalled?

Pumping CO2 underground can help fight climate change but remains untested for the most part March 12, 2015  | By  Howard J. Herzog  and  The Conversation US Injection of CO2 and other gases into geological formations has been practiced for many years.  Credit:  SaskPower There are many uncertainties with respect to global climate change, but there is one thing about which I have no doubts: we will not solve climate change by running out of fossil fuels. Understanding this leads to three posible pathways we can follow to lower greenhouse gas concentrations, and explains why I’ve chosen to focus  my research  on carbon capture and storage. We can: continue to burn fossil fuels with little or no restrictions. We will blow by atmospheric CO2 concentrations of 450 parts per million (ppm), the level many scientists think is dangerous to exceed, and we will keep on going. We have enough fossil fuels to easily go above 1,000 ppm. The impac...
