An answer to: Is the rise in sea levels accelerating?

Watts Up With That?

Guest essay by: Jan Kjetil Andersen

There is a well-established consensus concluding that the global sea level has risen over the last century, and that the level continues to rise. However, the question about whether the rate is accelerating or not, is more inconclusive.

To cast some light on this, I have analyzed the latest scientific papers on this topic. Thereafter I made my own time series analyzes based on tide gauges in the GLOSS network.

All data and software used in the analysis are available for download. See links in the end of the article.

I invite the readers to a discussion about the conclusions.

Firstly the findings from the academic papers:

I start by the IPPC AR5.

Chapter 3 is about Ocean observations, and here is exactly what I am looking for:

Renewables are useless: The Evidence is Overwhelming

Watts Up With That?

Guest essay by Eric Worrall

Al Gore has a problem. He seems to want people to believe that only climate skeptics oppose renewables. The truth is, a small but growing number of prominent greens, openly acknowledge that renewables in their current form are not a scalable replacement for fossil fuels.

In Al Gore’s announcement of a climate witch hunt, titled “AGs United for Clean Power”, Al Gore said the following;

I really believe that years from now, this convening by attorney general Eric Schneiderman and his colleagues today, may well be looked back upon as a real turning point, in the effort to hold to account those commercial interests that have been, according to the best available evidence, deceiving the American people, communicating in a fraudulent way, both about the reality of the climate crisis and the dangers it poses to all of us, and committing fraud in their…

The ‘Arctic Methane Emergency’ appears canceled due to methane eating bacteria

Watts Up With That?

Many readers know that we’ve covered the supposed “ticking time bomb” of methane that is supposedly going to be released somewhere, somehow, either from methane clathrates on the sea floor due to ocean warming, or from melting permafrost. Due to methane having a greater GHG warming factor,  a potential of 34 times that of CO2 over 100 years, there’s a perceived threat so great, that there’s a collection of scientists that have formed the Arctic Methane Emergency Group.

They made this King Canute style press release last year, where they called for a “rapid refreezing of the Arctic to halt runaway melting”, as if somehow we’ll just put a halt to those processes with a wave of the hand:

FOR IMMEDIATE RELEASE:

TIME: Thursday, December 4, 2014, 12:00-12:30 PM

SUBJECT: Arctic meltdown: a catastrophic threat to our survival
AMEG calls for rapid refreezing of the Arctic to halt…

Scientists: no proof polar bears undergoing climate crisis

Another manufactured climate scare takes a dive. Faulty science seems to be the issue. Nothing to see here, move along please!
H/T The Daily Caller

A new study by Canadian scientists once again debunks the notion polar bears are currently being harmed by global warming. Researchers with Canada’s Lakehead University found “no evidence” polar bears are currently threatened by warming.

Ooops! Alarm over ‘sinking Islands’ premature as sea level falls at Kwajalein Atoll

Watts Up With That?

David Burton writes:

Remember this little article by Nils-Axel Mörner, not quite three years ago?

The Marshall Islands and their Sea Level Changes

He discussed Kwajalein Atoll, in the Marshall Islands, where there’s a tide gauge that seemed to be measuring accelerated sea-level rise:

Of course, the Climate Community sounded the alarm. “Sinking islands call for NZ action,” trumped the New Zealand Herald. “Low-lying islands face existential threat from rising sea levels,” declared the Bangladesh Daily Star.

But Nils warned against drawing panicked conclusions from just one tide gauge. He pointed out that the apparent surge in sea-level at Kwajalein was atypical, and thus unlikely to herald an acceleration in global sea-level rise. He speculated that it could be due to local factors, such as subsidence caused by local construction projects. “In conclusion, don’t “hang your hat” on the Kwajalein graph,” he wrote.

Court Orders Release of White House Climate Documents

Watts Up With That?

Holdren_polar_vortex

Guest essay by Eric Worrall

The Competitive Enterprise Institute has won a case against the White House, forcing the release of documents pertaining a climate video created by White House Science Advisor John Holdren. When the content of Holdren’s climate video challenged under the federal Information Quality Act, the White House claimed the video was the “personal opinion” of John Holdren, not an official communication, and therefore not subject to the Act. The newly released emails allegedly cast doubt on this assertion.

On January 8, 2014, the White House posted a controversial video claiming that global warming causes more severe winter cold. Called “The Polar Vortex Explained in 2 Minutes,” it featured the director of the White House Office of Science & Technology Policy (OSTP), John Holdren, claiming that a “growing body of evidence” showed that the “extreme cold being experienced by much of the United States” at…

“I am Spartacus!”: Stand up and be counted for science

Tallbloke's Talkshop

Strong words softly spoken. This morning, I noticed someone had visited and commented on an old thread from last year about the Republican vote to defund the IPCC. The comment showed a strong belief in science, and condemnation of the way politics and other non-scientific forces have tried to turn science into a tool of propaganda. What impressed me the most was that this is a person of good standing in the science community, who was prepared to put his full name and list his qualifications and institutional affiliation at the bottom of his comment.

IPCC should not only be defunded, it should be deleted as an agency. The reason is its misuse of the concept of science. It has never been meant to rely on correct science and uses science for one simple reason. People believe in science, since people have seen the result of powerful applications of…
