Atlantic Multidecadal Oscillation

Persistent Pause Perplexes Climate Catastrophists

A few months back, the climate charlatans at the National Oceanographic and Atmospheric Administration (NOAA) made headlines by declaring the 18+ year pause in global warming a hoax, or at least a misunderstanding. In June 2015, NOAA scientists published an online article in the journal Science finds that the rate of global warming during the last 15 years has been as fast as or faster than that seen during the latter half of the 20th Century. Their study claimed to refute the notion that there has been a slowdown or “hiatus” in the rate of global warming. Climate change alarmists were ecstatic, the Pause was dead, long live global warming! Now, showing how settled the science behind climate change really is, a new paper in Nature Climate refutes the refutation. In a warmist's nightmare zombie Apocalypse, the Pause is back and NOAA stands revealed as the data fudging climate change activists they are.

The Tide Is Turning, Time For Global Cooling

Climate scientists have constructed models to predict what Earth's climate will look like decades, even hundreds of years in the future. Unfortunately, many major components of Earth's climate system have not been accurately monitored for very long. This makes such predictions suspect if not laughable. A case in point are variations in ocean circulation and temperature. In the Atlantic there is a cycle for sea surface temperatures variation called the Atlantic Multidecadal Oscillation (AMO). The AMO is linked with decadal scale climate fluctuations like European summer precipitation, rainfall in Europe and India, Atlantic hurricanes and variations in global temperatures. A new study in the journal Nature reports that the AMO is again transitioning to a negative phase, meaning the vaunted “pause” in global warming may be with us for decades. In fact, scientists at the University of Southampton predict that cooling in the Atlantic Ocean could cool global temperatures a half a degree Celsius.

Atlantic Currents Cause European Climate Change

Climate change alarmists point to the past several decades of European weather to reinforce their claim that global warming has the continent in its grip. A new report shows that this recent warm spell is nothing abnormal or unprecedented—during the 1990s there was simply a return to conditions present during 1931-1960. The reason for the shift is warm ocean temperatures that are, in turn driven by variation in warm ocean currents from the tropics. The instrumental record shows that, relative to the average temperature of the rest of the world’s oceans, the temperature of the North Atlantic Ocean has fluctuated between anomalously warm and anomalously cool phases, each lasting several decades at a time. Palaeoclimate records suggest that similar variations extend much farther back in time. The observed pattern of multidecadal variation in North Atlantic sea surface temperatures (SSTs) has become known as the Atlantic Multidecadal Oscillation (AMO).
