No, The Oceans Did Not Begin To Rise With The Advent Of Fossil Fuel

Posted on by

Yesterday The Washington Post posted an article about some new information on climate change and rising oceans. The facts simply do not support the idea of the catastrophic sea-level rise that those who practice the religion of global warming have predicted.

The article reports:

In her latest paper, Ms. Curry  (Climatologist Judith Curry) found that the current rising sea levels are not abnormal, nor can they be pinned on human-caused climate change, arguing that the oceans have been on a “slow creep” for the last 150 years — before the post-1950 climb in carbon-dioxide emissions.

“There are numerous reasons to think that projections of 21st-century sea level rise from human-caused global warming are too high, and some of the worst-case scenarios strain credulity,” the 80-page report found.

Her Nov. 25 report, “Sea Level and Climate Change,” which has been submitted for publication, also found that sea levels were actually higher in some regions during the Holocene Climate Optimum — about 5,000 to 7,000 years ago.

“After several centuries of sea level decline following the Medieval Warm Period, sea levels began to rise in the mid-19th century,” the report concluded. “Rates of global mean sea level rise between 1920 and 1950 were comparable to recent rates. It is concluded that recent change is within the range of natural sea-level variability over the past several thousand years.”

Such conclusions are unlikely to find favor with the global-warming movement, or within the academic climate “consensus,” where some experts have predicted that mean sea level could rise by five to 10 feet by the end of the 21st century.

The article concludes:

She said she doesn’t believe her findings on sea-level rise are particularly controversial, saying that they jibe with those of the U.N.’s Intergovernmental Panel on Climate Change.

“It’s pretty well-documented in the literature,” said Ms. Curry. “I frame the problem a little different, and my conclusions are a little different than some people, but this has been pretty well-documented and supported.”

Ms. Curry left academia in January 2017 for a host of reasons, one of which was the “craziness” associated with the politics of the climate-change debate. She moved to Reno and has since devoted her energies to her company, Climate Forecast Applications Network.

Her clients include the federal agencies and companies in the energy and insurance business seeking answers on the risks associated with climate change. After a lifetime spent in the ivory tower, she said she finds the real-world work rewarding.

“When there’s something that really depends on the outcome and the understanding of this information, rather than just using it as a political tool to drive policy, it’s really a different ballgame,” she said. “People making real decisions, people spending real money — their companies could be hurt by getting things really wrong in either direction. So that’s what I’m trying to help with.”

Given that nobody wants to be labeled a “denier,” what does she prefer to be called? That’s an easy one.

“I’m a scientist. And I regard it as my job to continually reevaluate the evidence and reconsider my conclusions. That’s my job,” Ms. Curry said. “And some people don’t really want scientists. They want political activists. But if you want a scientist, give me a call.”

Maybe at some point we can end the hysteria and get back to science.

Was 2014 Really The Hottest Year On Record?

Posted on by

We all remember seeing cartoons showing people holding signs saying, “The End Is Near.” The captions varied, but generally speaking the implication was that the end really wasn’t near. That is where we find ourselves with recent headlines stating that 2014 was the hottest year in the history of the earth.

The following chart appears on the website green-agenda.com:

The following chart is from Power Line:

As you can see, the climate models show the earth getting warmer, but the actual temperatures show that the temperature of the earth has been cooling for the past ten years or so. Some scientists say that the earth has not warmed for eighteen years.

Climate Depot reports:

Climate Depot’s Marc Morano issued this statement: “There are dueling global datasets — surface temperature records and satellite records — and they disagree. The satellites show an 18 year plus global warming ‘standstill and the satellite was set up to be “more accurate” than the surface records. See: Flashback: 1990 NASA Report: ‘Satellite analysis of upper atmosphere is more accurate, & should be adopted as the standard way to monitor temp change.’

Any temperature claim of “hottest  year” based on surface data is based on hundredths of a degree hotter than previous “hottest years”. This immeasurable difference is not even within the margin of error of temperature gauges. The claim of the “hottest year” is simply a political statement not based on temperature facts. “Hottest year” claims are based on minute fractions of a degree while ignoring satellite data showing Earth is continuing the 18 plus year ‘pause’ or ‘standstill’. See: The Great Pause lengthens again: Global temperature update: The Pause is now 18 years 3 months (219 months)

As you can see, the end isn’t really near, but given today’s political climate, the easiest way to receive grant money is to claim that there is a crisis either currently occurring or about to occur. The climate is cyclical–there are natural cycles. Unfortunately, the study of normal cycles does not guarantee grant money.

Just for the record, the green-agenda website also reports:

The Medieval Warm Period was a time of warm weather around 800-1300 AD, during the European Medieval period. Initial research on the MWP and the following Little Ice Age (LIA) was largely done in Europe, where the phenomenon was most obvious and clearly documented. The Vikings took advantage of ice-free seas to colonize Greenland and other outlying lands of the far north.

“The climate at this time was very warm, much warmer than it is today, and crops were able to do well. It seems likely that the name “Greenland” was given to the country, not just as wishful thinking, but because it was a climatic fact at that time. The mild climatic period was fairly short-lived in geologic terms – by about 1200 AD, the ever-increasing cold was making life extremely difficult, and some years no supply ships were able to reach Greenland through the ice-choked seas. During this period, Norway had assumed responsibility for supplying the Norse settlers in Greenland, but as the climate worsened it became a very difficult task.

I really do think global warming might not be a bad thing.

Yesterday the U.K. Daily Mail posted a story that will create some problems for those who believe that global warming is man-made and caused by our use of carbon fuels. Recent evidence shows that global warming occurred in the Middle Ages in many areas of the world.

The article reports:

A team of scientists led by geochemist Zunli Lu from Syracuse University in New York state, has found that contrary to the ‘consensus’, the ‘Medieval Warm Period’ approximately 500 to 1,000 years ago wasn’t just confined to Europe.

In fact, it extended all the way down to Antarctica – which means that the Earth has already experience global warming without the aid of human CO2 emissions.

Whoops.

Professor Lu based his conclusions on a rare mineral called ikaite, which forms in cold waters.

The article explains:

It turns out the water that holds the crystal structure together – called the hydration water – traps information about temperatures present when the crystals formed.

This finding by Lu’s research team establishes, for the first time, ikaite as a reliable way to study past climate conditions

The article further reports:

The scientists were particularly interested in crystals found in layers deposited during the ‘Little Ice Age,’ approximately 300 to 500 years ago, and during the Medieval Warm Period before it.

Both climate events have been documented in Northern Europe, but studies have been inconclusive as to whether the conditions in Northern Europe extended to Antarctica.

Lu’s team found that in fact, they did.

Now that we have a reliable way of studying past climate conditions, we may be able to actually understand the things that do actually impact our global temperatures.
