The underestimated danger of a breakdown of the Gulf Stream System

A new study has shown that a 2015 NOAA paper finding that the Earth is warming more rapidly than previously thought was correct. Possible artifacts of data biases in the recent global surface warming hiatus | Science
Hausfather Z, Cowtan K, Clarke DC, Jacobs P, Richardson M, Rohde R. Assessing recent warming using instrumentally homogeneous sea surface temperature records. Science Advances 2017;3(1). Assessing recent warming using instrumentally homogeneous sea surface temperature records | Science Advances
Sea surface temperature (SST) records are subject to potential biases due to changing instrumentation and measurement practices. Significant differences exist between commonly used composite SST reconstructions from the National Oceanic and Atmospheric Administration’s Extended Reconstruction Sea Surface Temperature (ERSST), the Hadley Centre SST data set (HadSST3), and the Japanese Meteorological Agency’s Centennial Observation-Based Estimates of SSTs (COBE-SST) from 2003 to the present. The update from ERSST version 3b to version 4 resulted in an increase in the operational SST trend estimate during the last 19 years from 0.07° to 0.12°C per decade, indicating a higher rate of warming in recent years. We show that ERSST version 4 trends generally agree with largely independent, near-global, and instrumentally homogeneous SST measurements from floating buoys, Argo floats, and radiometer-based satellite measurements that have been developed and deployed during the past two decades. We find a large cooling bias in ERSST version 3b and smaller but significant cooling biases in HadSST3 and COBE-SST from 2003 to the present, with respect to most series examined. These results suggest that reported rates of SST warming in recent years have been underestimated in these three data sets.
Agreed by 195 countries in December 2015, the Paris climate deal was billed as an historic game-changer by UN officials when it came into force last November.
Not everyone is convinced, least of all the respected climate economist William Nordhaus, who dimisses the deal as “rhetoric” in a new paper.
The Yale academic – who has explored the implications of climate change since the early 1990s – ran the numbers through his economic model known as DICE and came up with some bleak answers.
“The international target for climate change with a limit of 2C appears to be infeasible with reasonably accessible technologies – and this is the case even with very stringent and unrealistically ambitious abatement strategies,” he writes.

Well i blame all the country's for global warming. since the 40's there have been 1500+ atomic bomb test which i say contribute to almost all of global warmimg. My numbers might be slightly off since i read that shit years ago so it may be a little less or a whole lot more i dont know.

Private-sector incentives help drive decoupling of emissions and economic growth.
The release of carbon dioxide (CO2) and other greenhouse gases (GHGs) due to human activity is increasing global average surface air temperatures, disrupting weather patterns, and acidifying the ocean.
Left unchecked, the continued growth of GHG emissions could cause global average temperatures to increase by another 4°C or more by 2100 and by 1.5 to 2 times as much in many midcontinent and far northern locations.
Although our understanding of the impacts of climate change is increasingly and disturbingly clear, there is still debate about the proper course for U.S. policy—a debate that is very much on display during the current presidential transition.
But putting near-term politics aside, the mounting economic and scientific evidence leave me confident that trends toward a clean-energy economy that have emerged during my presidency will continue and that the economic opportunity for our country to harness that trend will only grow.
This Policy Forum will focus on the four reasons I believe the trend toward clean energy is irreversible.

Looks like Scally will try keep this thread going until the next ice age rolls in.
Climate has been changing for a few billion years now, time to move on.

BTW, this thread is fucking annoying to load because of all the tweets.

Here's something for those of us who like FACTS, and not mildly retarded tweets...
I guess my ancestors, the Vikings, must have been using some seriously polluting outboard engines on their longboats?
They navigated the Arctic, they settled the area, because it was WARM and free of ice!
You man-made global warming nut jobs are full of it.

"The possibility that global warming might contribute to Arctic development isn’t anything new. America’s first European visitors, the Vikings, were able to reach and colonize the northernmost reaches of the continent due to the lack of sea ice covering the Arctic Ocean during Medieval times when the earth was going through a warming period.
The Viking era came well before the Industrial Revolution — when humans began burning large amounts of fossil fuels which some scientists say causes global warming — and suggests that there are strong natural climate forces that have a profound effect on the extent of Arctic sea ice coverage. However, this is not a new theory — it was discussed as far back as the 19th century.
According to an 1887 newspaper article entitled “Variations in Climate,” Scandinavian Vikings were able to sail through the Arctic Ocean and establish colonies in the “highest north latitude” of Greenland and North America centuries before the arrival of Christopher Columbus. These colonies, however, were abandoned by the Vikings due to “the increasing cold.”
“On the contrary, the formation of ice increases annually if the winters are strongly cold, long and dark,” wrote Alexander Beck in 1887. “The reverse of that state of things is found by calculations for the year 1122 A.D., and it is precisely at that time we find the Danes and other Scandinavian nations going through the Arctic open seas.”
“Colonies are established by them in the highest north latitude of Greenland, and the upper part of North America, a long time before Christopher Columbus had reached a more southern part of the same continent,” Beck added. “But those colonies were relinquished on account of the increasing cold. In the fourteenth century the seas are found again closed, even in the summer. The great north icefield … increases daily, the Arctic colonists are compelled to come more to the south, and the cold takes possession again of countries which were kept free for a few years just about the twelfth century.”
“Remains of those upper Arctic villages are found, I may say, in each Arctic expedition. The climate of Iceland becoming more and more cool also proves that the state of the earth varies in the course of centuries,” Beck continued.
The warm climate that defined the Middle Ages and allowed the Vikings to settle the most northern reaches of the Americas is known as the “Medieval Warming Period,” which lasted from the 9th century A.D. to the 13th Century A.D. During this time temperatures were warmer in the Northern Hemisphere than the so-called “Little Ice Age” that followed, according to the National Climate Data Center.
The “Little Ice Age” that followed the warmer Medieval period lasted from the 14th century A.D. to the late 19th Century A.D. Some scientists argue that this period coincided with low sunspot activity which cooled the climate substantially during this time period. Others say that it had to due with natural climate variations caused by the Atlantic Ocean.
Recently, German scientists have argued that two naturally occurring cycles will combine to lower global temperatures to levels corresponding with the “Little Ice Age” of 1870. According to scientists declining solar activity and the 65-year Atlantic and Pacific Ocean oscillation cycle will cause the earth to cool during this century.
“Due to the de Vries cycle, the global temperature will drop until 2100 to a value corresponding to the ‘little ice age’ of 1870,” write German scientists Horst-Joachim Luedecke and Carl-Otto Weiss of the European Institute for Climate and Energy.""
