Greener Pastures

CO2, Carbon DiOxide, green, greenhouse, warming, climate,

There is climate change going on. And some of it is attributable to increasing levels of Carbon dioxide (CO2). 

It is uncontroversial and quite politically convenient to say that — despite Al Gore’s infamous propaganda positing climate change dogma as An Inconvenient Truth. The worldwide “green” movement to “fight climate change” has been supported by trillions of tax dollars and the eager, lip-​smacking glee of major media mavens as they trot out story after improbable story, linking every storm, warm spell, cold spell, and summer ice melt to “man-​made global warming.”

But there is no real “settled science” as non-​scientists like to term the case for anthropogenic global warming, because there are

  1. troubles with the temperature data, 
  2. difficulties separating weather events from climatic trends, 
  3. problems identifying CO2 level variations as the cause of climate change rather than as a result,
  4. a certain amount of dunderheadedness using a statistical construct of “average global temperature” to track actual trends, and 

so much more. But we do know about one extremely positive effect of increasing atmospheric carbon: it makes the deserts bloom.

Or, at least, greener.

Six years ago a study of satellite data concluded that arid regions have gone greener. Increased atmospheric CO2 levels makes photosynthesis more efficient, allowing plants to use less water, thereby creating more leaves.

Earlier this year, however, Forbes reported that a NASA study had just demonstrated that expanded agriculture and silviculture in India and China were responsible for most of that greening — but if you compare the Forbes article with the original paper, the CO2 contribution persists. 

Atmospheric carbon is plant food, so to speak, and without it, life on the planet would die.

An awkward truth?

Skepticism in Order

denier, climate change, globlal warming, skepticism, science

It is not a question of “belief,” says Anastasios Tsonis. 

In “The overblown and misleading issue of global warming,” this emeritus distinguished professor at the University of Wisconsin-​Milwaukee explains that in a “scientific problem ‘believing’ has no place,” going on to clarify: 

“In science, we either prove or disprove.”

And regarding climate there is no “settled science.” Lacking unquestionable experimental context — “we have only one realization of climate evolution” — no matter how strong our opinions, skepticism is always in order.

But let us admit the obvious, the “global warming”/“climate change” debate has been frustrating for just about everybody. And much of this is the result of dogmatism.

“The fact that scientists who show results not aligned with the mainstream are labeled deniers is the backward mentality,” Tsonis insists. “We don’t live in the medieval times, when Galileo had to admit to something that he knew was wrong to save his life.”

He argues that our lack of knowledge means that we should be circumspect about whether humans have caused the bulk of recent climate change. “Climate is too complicated to attribute its variability to one cause. We first need to understand the natural climate variability” — which, he says, “we clearly don’t.” 

Tsonis concludes talking about problems more urgent than climate change. We can (and should) quibble with his list, but we should be open about our reasoning.

One reason for concentrating on these other issues is that we might be more likely to gain clarity on them.

And thus might be able to do something not foolish.

This is Common Sense. I’m Paul Jacob.

Settling the Science

climate, global warming, climate change, science, mistake

A paper in the august science journal Nature,* on the oceans’ “thermal inertia” and the ominous temperature rise therein, has been corrected. But not before the BBC (and other media outlets) ballyhooed the results in the usual “climate change”/“global warming” narrative: “Climate change: Oceans ‘soaking up more heat than estimated’” (Nov. 1).

The paper’s initial new (and alarming) estimate, however, proved wrong.

Over at Real Climate, one of the co-​authors clarified the changes that had to be made: “The revised uncertainties preclude drawing any strong conclusions with respect to climate sensitivity or carbon budgets … but they still lend support for the implications of the recent upwards revisions in” … well, I will let you make sense of it.

I am not a climate scientist, nor do I pretend to be one on the Internet.

What is important to note is that the “strong conclusions” reported on were found to be groundless. 

Mistakes were made.

How were those mistakes identified?

They were caught at the ClimateEtc. — not an “august science journal” — published online at judithcurry​.com.**

Nic Lewis, the astute blogger, identified a major source of the inaccuracy in the original paper as having arisen “primarily because of the inappropriate assumption of a zero error in 1991.”

We have just witnessed science in action — the public testing of published findings.

“The bad news,” Dr. Roy Spencer reminds us on his Global Warming blog, “is that the peer review process, presumably involving credentialed climate scientists” — note the dig — failed to catch the error “before publication.”

The crucial science happened afterwards, online. 

This is Common Sense. I’m Paul Jacob.

Sledgehammer to a Bureaucracy

EPA, environment, pollution, climate change, Trump

The media hysterically pushes the line that the new Trump administration is so much “in chaos” it even frightens seasoned (salt-​and-​pepper?) heads in the Republican Party. But perhaps folks at the Environmental Protection Agency have more reason to panic.

“It looks like the EPA will be the agency hardest hit by the Trump sledgehammer,” writes Julie Kelly over at National Review.

Ms. Kelly offers striking reasons to hit the agency hard, quoting from Steve Malloy, the author of Scare Pollution: Why and How to Fix the EPA. “I can think of no agency that has done more pointless harm to the U.S. economy than the EPA — all based on junk science, if not out-​and-​out science fraud.” Malloy looks forward to the new president’s promised rethink and restructuring of the agency.

Just how bad is it?

Environmentalists often cry foul over any corporate funding of ecological research. But if one worries about money influencing results, the case against grants funded by regulatory agencies for regulatory purposes is even stronger.

Especially when the agency is run by ideologues.

Trump’s transition team seeks to make all the EPA’s relevant data public, for peer and public review, and would really like to curtail the agency’s research funding entirely.

Pipe dream? Better than the recent nightmare: “For eight years,” writes Kelly, “President Obama used the agency as his de facto enforcer of environmental policies he couldn’t pass in Congress even when it was controlled by his own party.”

The EPA needs to be checked. And balanced. And more.

This is Common Sense. I’m Paul Jacob.

Climate Change Assertions

Scott Pruitt, EPA, Global Warming, Climate Change, illustration

I know Scott Pruitt, Donald Trump’s pick to head the EPA; he replaced the egregious Drew Edmondson as Oklahoma Attorney General.

Pruitt seems like a good man.

But Sen. Bernie Sanders (I‑Vt) says different. “Mr. Pruitt’s record is not only that of being a climate change denier, but also …”

Wait: that “climate change denier” charge is everywhere. But all I’ve seen is assertion.

It would indeed be weird were he — or anyone — to deny the reality of climate change. Way back in my Seventies’ youth, I saw all sorts of climate change articles … predicting a new Ice Age.

Decades later, the headlines began to change: Global Warming was in.

But note: those Seventies’ articles usually mentioned that the world had been heating out of the recent Little Ice Age, with the thaw beginning before the dreaded Industrial Revolution.

I bet that what our new Trump pick really believes is that

  • warm weather is generally better than cold weather;
  • CO2 is not a poison as such (plants thrive with more carbon dioxide);
  • every major climate model has predicted more warming than we’ve experienced; and
  • stifling progress to offset poorly understood climate events would be disastrous, especially for the poor.

Betting aside, what does Pruitt believe? The Advocate actually repeats the disproven “97 percent of climate scientists” meme to pile on the abuse*, but did link to a National Review article Pruitt co-​authored with Alabama’s attorney general.

They did not deny climate change, merely insisting that “the debate is far from settled.” More importantly, they argued that governments should not intimidate energy companies in service to the climate cause. Instead, they called for open debate.

Shocking!

This is Common Sense. I’m Paul Jacob.

 

* The Advocate also irrelevantly charged Pruitt with “transphobia.” But then, Trump’s Small Business Administration pick, Linda McMahon, has also been tarred with the “climate denier” charge, which is as irrelevant to an SBA head as vegetarianism would be for a Secretary of Treasury.
