Southern Hemisphere Cooling the Trend is Now Apparent | Mini Ice Age 2015-2035

Publisert 7. jun. 2017

With the Southern Hemisphere winter getting underway we need to look back at trends to see the future of the coming year. David Archibald has today given the most up to date information on our Sun entering a grand solar minimum and the State of the Sun, now with the past 5 winters under our belts we can look for trends. I present to you the trend of a cooling Southern Hemisphere.

Trump CLEXIT as Earth Begins to Cool, Media Overlooks Mini Ice Age Observations

Publisert 3. jun. 2017

With President Trumps pull out from the socialist re-distribution of wealth United Nations program the Paris Climate Accord / treaty, we can now get back to real science and looking at the facts that throughout history the Earths temperatures have always risen and fallen over multi century time frames, no CO2 needed. With the new grand solar minimum intensifying, I have put out a timeline for the amplification effects and we need a plan in place now to tell the planet what is unfolding and implement solutions to do so.This where President Trump / The Donald can excel. The time for change is now.

Claim: El Niño and global warming combine to cause record-breaking heat in Southeast Asia

From the UNIVERSITY OF TEXAS AT AUSTIN and the “what if it’s only El Niño, then what?” department:

Scientists at The University of Texas Institute for Geophysics (UTIG) have found that a devastating combination of global warming and El Niño is responsible for causing extreme temperatures in April 2016 in Southeast Asia.

The research, published on June 6 in the journal Nature Communications, shows that El Niño triggered the heat, causing about half of the warming, while global warming caused one-third and raised the heat into record-breaking territories, according to the team’s analysis. El Niño is a climate pattern that impacts the tropical Pacific, and usually brings warmer temperatures to Southeast Asia in April.

In April 2016, high temperatures in mainland Southeast Asia broke all previous records, exacerbating energy consumption, disrupting crop production and causing severe human discomfort in Cambodia, Thailand and other countries in the region. The especially high temperatures of 2016 made the researchers interested in investigating the factors behind such extreme heat, including the impact of the record-breaking El Niño of 2015 and whether ongoing global warming played a significant role in the event.

The researchers used computer model simulations designed to disentangle the natural and human-made causes of the extreme heat. They also used observations from land and ocean monitoring systems and found that long-term warming has played an increasing role in rising April temperatures in Southeast Asia. Since 1980, this trend has caused a new temperature record each April following an El Niño.

“The El Niño system primes mainland Southeast Asia for extremes, although long-term warming is undoubtedly exacerbating these hot Aprils,” said UTIG postdoctoral fellow Kaustubh Thirumalai, who led the study. UTIG is a research unit of the UT Austin Jackson School of Geosciences.

The researchers used statistical techniques to quantify the contributions from El Niño and from long-term warming. Their analysis looked at the 15 hottest April temperatures over the past 80 years. All of them occurred after 1980, and all of them but one coincided with El Niño. They found that while the impact of El Niño fluctuated over the years, the impact of global warming has steadily increased over time.

“Though almost 50 percent of the April 2016 event was due to the 2015-16 El Niño, at least 30 percent of the anomaly was due to long-term warming, and there’s definitely more to come in the future,” Thirumalai said.

Looking at the model predictions for the next 50 years, the researchers found that the impact of climate change could amplify the effects of each El Niño, leading to temperature records being broken more often.

“Because of long-term warming, even a weaker El Niño than the 2015-16 event in the mid-to-late 21st century could cause bigger impacts,” said co-author Pedro DiNezio, who is a research associate at UTIG.

Despite all the evidence pointing to worsening extremes, the researchers emphasized that preparedness could allow societies in this region to cope with climate change.

“The silver lining is that these can be predicted a few months in advance since they happen after the peak of an El Niño,” Thirumalai said.

Just a couple things:

  1. Only back to 1980? Hmm seems like cherry picking to me, While El Niño is a only recently known phenomenon, there are proxies that could indicate previous past ENSO strengths, which may have been even greater. To assume that 2016 is the largest because of a supposed [contribution] of global warming is pure folly, on many levels.
  2. They don’t know if the increase in SST is due to the previous Super El Nino and subsequent ones adding heat to the ocean in that area, or not. They don’t know if it’s a contribution of cloudiness (lack of it) or other factors. As many have observed, getting the atmosphere to heat the ocean is quite the trick. Direct solar insolation change is a far more likely candidate, as is wind patterns changing the surface albedo due to roughness. Have they considered algae, and turbidity too? How about population and infrastructure/land use changes in that area affecting temperature measurements over time?
  3. Here is what April 2016 looks like in that area, compared to April 2017, followed by the global map. Looks like SST cooling is imminent.

Now, look at the latest:

Bob Tisdale suggests that changes in the Pacific Warm Pool might be a factor:
