Oil and gas group says U.S. can cut emissions without Paris climate deal, urges withdrawal

A prominent oil and gas industry group said Monday the U.S. has dramatically reduced greenhouse-gas emissions without burdensome regulations and international deals, urging President Trump to withdraw from the landmark Paris climate agreement and let market forces drive energy policy. Kathleen Sgamma, president of the Western Energy Alliance, said the Paris deal — currently the […]

Oh noes! Antarctic ice rift spreads

Oh noes! Antarctic ice rift spreads

New branch revealed in latest data from ice shelf

The rift in the Larsen C ice shelf in Antarctica now has a second branch, which is moving in the direction of the ice front, Swansea University researchers revealed after studying the latest satellite data.

The main rift in Larsen C, which is likely to lead to one of the largest icebergs ever recorded, is currently 180 km long. The new branch of the rift is 15 km long.

Last year, researchers from the UK’s Project Midas, led by Swansea University, reported that the rift was growing fast. Now, just 20km of ice is keeping the 5,000 sq km piece from floating away.

Professor Adrian Luckman of Swansea University College of Science, head of Project Midas, described the latest findings:

“While the previous rift tip has not advanced, a new branch of the rift has been initiated. This is approximately 10km behind the previous tip, heading towards the ice-front.

This is the first significant change to the rift since February of this year. Although the rift length has been static for several months, it has been steadily widening, at rates in excess of a metre per day.

It is currently winter in Antarctica, therefore direct visual observations are rare and low resolution. Our observations of the rift are based on synthetic aperture radar (SAR) interferometry from ESA’s Sentinel-1 satellites. Satellite radar interferometry allows a very precise monitoring of the rift development”.

Researchers say the loss of a piece a quarter of the size of Wales will leave the whole shelf vulnerable to future break-up. Larsen C is approximately 350m thick and floats on the seas at the edge of West Antarctica, holding back the flow of glaciers that feed into it.

Professor Luckman said:

“When it calves, the Larsen C Ice Shelf will lose more than 10% of its area to leave the ice front at its most retreated position ever recorded; this event will fundamentally change the landscape of the Antarctic Peninsula.

We have previously shown that the new configuration will be less stable than it was prior to the rift, and that Larsen C may eventually follow the example of its neighbour Larsen B, which disintegrated in 2002 following a similar rift-induced calving event.

The MIDAS Project will continue to monitor the development of the rift and assess its ongoing impact on the ice shelf. Further updates will be available on our blog (projectmidas.org), and on our Twitter feed”

Brazil – Record Cold Threatens Safrinha Corn

Brazil – Record Cold Threatens Safrinha Corn

Record cold temperatures for the end of April. Farmers worry the next blast could be even colder. Safrinha corn needs to be frost free until at least early June to avoid potential damage.

28 Apr 2017 – According to the Brazilian National Institute of Meteorologia, temperatures in the higher elevations of the state of Santa Catarina fell to -1.1°C (30°F) on Thursday morning.

Temperatures all across southern Brazil are expected to set record lows below 10°C (50°F) for the next several nights in all of three state capitals including Curitiba in Parana, Florianopolis in Santa Catarina, and Porto Alegre in Rio Grande do Sul. The low temperatures Friday night in the state of Parana could drop to -5°C (23°F) in higher elevations with the possibility of frosts across the state until Sunday night.

Even if there is not a killing frost, the cold is not good news for safrinha corn. (For a killing frost to occur, the temperatures need to drop to 27°F to 28°F for three hours.)

The cold will slow development of the corn making it more susceptible to a future freezes. Farmers are concerned about just how early these cold temperatures have arrived.

Climatists Wrong-Footed

Climatists Wrong-Footed

Trolling: The art of deliberately, cleverly, and secretly pissing people off, usually via the internet, using dialogue.

People may not have noticed that subtly, without fanfare, the climate battleground has shifted from the science to the policy. Like everyone else climatists were caught unawares by the election of US policymakers skeptical of the need to “fight climate change.”

But the surprising development is how activist tactics are still geared mainly to push on the claim of “settled science”, when that is not any more the focal point for the opposition. I don’t know who created the strategy for nominees, but in confirmation hearings, to a man and woman they all refrained from denying the science. Sanders and the other true-believing senators pressed hard to get heretical statements, but failed.

Now the activists have turned up the heat with science marches every weekend. Activists keep pushing on the science because their policy agenda is even less believable.

Like a three-legged stool, the marchers’ signs show they depend on three suppositions:

  • Humans are making the planet warmer.
  • The warming is dangerous.
  • Government can stop it.

The first point is what alarmists claim is settled science, and where others have doubts about the data, the models and the theories. Expressing those doubts gets you labeled a denier. After years of alarmists refusing to debate that first point, they now want to talk about nothing else. They think, apparently think that only the first point matters; once that is admitted, everything else follows.

To their surprise, policymakers, and now even some journalists are shifting the ground to the other two wobbly legs, where the assertions have even less support.

A perceptive journalist writing for the LA Times sees how the game is changing.  Jonah Goldberg wrote yet another piece of independent thought coming from a previous uncritically warmist newsroom. Bret Stephens just trolled the left with his supposed climate change denialism. Excerpts below.

The most amusing show over the weekend was the collective case of the vapors across the liberal left establishment over Bret Stephens’ first column at the New York Times on the perils of certainty, particularly on the topic of climate change.

When someone says that he is not denying climate change and concedes that it is real, that is “classic climate change denialism”? Huh. What words do we have left for people who call the whole thing a “hoax”? In civil debates, when someone concedes much of your premise, the proper reaction is not to scream “liar!” or “heretic!”

And that brings me to the second, and more amusing, thing about all of this. You’ve been trolled, people.

As a fellow columnist, I doff my cap to you, sir.

It wasn’t hard to trick liberals into going off-sides. In the past, Stephens was a more acid-tongued critic of climate change research. But the column in question was a model of restraint that, when read by non-ideologues and non-combatants, must seem utterly reasonable, even a tad banal. Stefan Rahmstorf, a prominent German climate scientist, wrote a lengthy, sanctimonious letter explaining why he was cancelling his subscription to the New York Times. Nothing in the letter addressed anything Stephens wrote in his column.

The Washington Post’s Eric Wemple found it hard to constrain his dismay. “May it suffice to say, however, that the many, many people who care passionately for the planet found it an exercise in climate-change denialism.”

Wemple’s a clever fellow. I’m sure he understands Stephens’ point about the dangers of certainty, particularly based on sophisticated mathematical models that have been proven wrong in the past.

What I think sailed past Wemple and so “many, many people” was Stephens’ subtler point about the sanctimonious condescension of people who claim to be motivated solely by their passionate care for the planet.

Stephens’ heresy here isn’t in denying climate change; it’s in refusing to concede that one group of people has a total monopoly on defining not just the problem but the acceptable responses to it. Such dissent is not a crime against science; it’s a threat to a guild. And the guild took the bait.
