More worrying than global warming – report on ‘extreme space weather’ shows risks to Earth

Watts Up With That?

Extreme space weather has a global footprint and the potential to damage critical infrastructure on the ground and in space. A new report from the European Commission’s Joint Research Centre (JRC) calls for bridging knowledge gaps and for better coordination at EU level to reduce the potential impact of space weather events.

The sun shapes the space environment around the Earth. This so-called space weather can affect space assets but also critical infrastructure on the ground, potentially causing service disruptions or infrastructure failures. Numerous space weather events affecting the power grid, aviation, communication, and navigation systems have already been documented.

The impact of severe space weather can cross national borders, which means that a crisis in one country can affect the infrastructure in the neighbouring countries. This raises concerns due to the increasing reliance of society on the services that these infrastructures provide.

New report identifies knowledge gaps

A serious climate opportunity

Watts Up With That?

Why does government refuse to do the one thing that would help our forests and climate?

Guest essay by Greg Walcher

For years, politicians have waged war on coal, stifled oil and gas production, and advocated carbon taxes and other extreme measures to reduce carbon dioxide, while ignoring one of the most important things they could do to help.

It reminds me of my own lifelong battle with weight and the associated health issues. I get so frustrated that I sometimes swear I would do anything – anything! – to lose weight. Well, anything except eat less and exercise. But anything else.

That same kind of hypocrisy surrounds rants about our carbon dioxide emissions. Even people who are “deeply concerned” about dangerous manmade climate change drive cars, heat their homes, and sometimes even turn on lights. They embrace modern living standards, while also embracing faddish environmental claims and policies that…

“No country would find 173 billion barrels of oil in the ground and just leave them there.”

Watts Up With That?

Guest post David Middleton

Multiple Choice Quiz

“No country would find 173 billion barrels of oil in the ground and just leave them there.”

  • a. Chairman of BP Capital Management, T. Boone Pickens
  • b. U.S. President Donald Trump
  • c. U.S. Secretary of State Rex Tillerson
  • d. Canadian Prime Minister Justin Trudeau
  • e. Saudi Arabia’s Minister of Energy, Industry and Mineral Resources, Khalid A. Al-Falih

The answer is “d”…



“No country would find 173 billion barrels of oil in the ground and just leave them there.”

Perhaps that’s true, but it certainly still is a betrayal of the image that he crafted for himself in recent years as someone “who cares” about the climate. Unsurprisingly (since the crowd was full of oil and gas execs), Trudeau received “an unusually warm reception” for the speech, as reported by Business Insider.

Trudeau continued: “The resource will be developed. Our job is to ensure…

Alan Carlin: A particularly troublesome aspect of climate alarmism

Tallbloke's Talkshop

Had enough of climate propaganda?
Last week EPA Administrator Scott Pruitt stated that: “I think that measuring with precision human activity on the climate is something very challenging to do, and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see.”

I can only applaud Pruitt’s thoughtful comments, writes Alan Carlin.

But in fact there is not just uncertainty as Pruitt said, but actual evidence that there are no significant effects of rising human-caused emissions or atmospheric CO2 levels on global temperatures.

Study: why CO2 levels are lower during global cold periods

Watts Up With That?


Deep-sea corals reveal why atmospheric carbon was reduced during colder time periods

We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international team of scientists reveals one of the mechanisms by which a colder climate was accompanied by depleted atmospheric CO2 during past ice ages.

The overall goal of the work is to better understand how and why the earth goes through periodic climate change, which could shed light on how man-made factors could affect the global climate.

Earth’s average temperature has naturally fluctuated by about 4 to 5 degrees Celsius over the course of the past million years as the planet has cycled in and out of glacial periods. During that time, the earth’s atmospheric CO2 levels have fluctuated between roughly 180…

Some WUWT milestones and some housekeeping

Watts Up With That?

Recently, this blog passed a few milestones that I thought would be worth sharing with readers. For all of our critics and the vitriol all they throw our way, I challenge any of them to find a climate related blog that even comes close to the level of readership we enjoy here. We recently passed 300 million views and 2 million approved comments (more on that later).Here are screen grabs from the WUWT dashboard showing the numbers:

We also recently passed 40,000 email subscribers.

Given these events, I thought it might be time to refresh some of our readers on the most contentious part of operating this blog and that is the comments section. One of the downsides of being number one is that you’re also the biggest target. And being the biggest target we have a plethora of “anonymous cowards” who try to post comments here that are either…

A perfect storm of fire and ice may have led to snowball Earth

Watts Up With That?

Explaining a ‘once-in-a-billion-year event’

About 700 million years ago, runaway glaciers covered the entire planet in ice. Harvard researchers modeled the conditions that may have led to this so-called ‘snowball Earth’.
CREDIT (Image courtesy of NASA)

What caused the largest glaciation event in Earth’s history, known as ‘snowball Earth’? Geologists and climate scientists have been searching for the answer for years but the root cause of the phenomenon remains elusive.

Now, Harvard University researchers have a new hypothesis about what caused the runaway glaciation that covered the Earth pole-to-pole in ice.

The research is published in Geophysical Research Letters. (paywalled)

Researchers have pinpointed the start of what’s known as the Sturtian snowball Earth event to about 717 million years ago — give or take a few 100,000 years. At around that time, a huge volcanic event devastated…

Science Funding Misinformation

Big Picture News, Informed Analysis

A headline on a news story falsely claims that ‘9 countries outspend the US on science.’ In fact, America spends more than all nine combined.


Seeking firm numbers regarding the amount of money the United States spends on scientific research, I recently typed the following phrase into Google:

US R&D spending versus other countries nations

A list of results appeared, the first of which was a link to Wikipedia, not always the most reliable source. The second was an outrageously inaccurate headline from Business Insider. It declared that “9 countries outspend the US on science”:


This is a shameful example of fake news. Of distorting reality. Of telling people the opposite of the truth.

Clicking the link took me to a page with a slightly different headline: “These 9 countries spend a greater share of money on science than the United States.” The news story, published a year ago, is about an OECD…

Uh-oh, G-20 Poised To Signal Retreat From Paris Climate Deal Pledge

Watts Up With That?

From Bloomberg, 11 March 2017 (h/t to GWPF) by Joe Ryan
Finance ministers for the U.S., China, Germany and other members of the Group of 20 economies may scale back a robust pledge for their governments to combat climate change, ceding efforts to the private sector.

Citing “scarce public resources,” the ministers said they would encourage multilateral development banks to raise private funds to accomplish goals set under the 2015 Paris climate accord, according to a preliminary statement drafted for a meeting that will be held in Germany next week.

The statement, obtained by Bloomberg News, is a significant departure from a communique issued in July, when finance ministers urged governments to quickly implement the Paris Agreement, including a call for wealthy nations to make good on commitments to mobilize $100 billion annually to cut greenhouse gases around the globe.
“It basically says governments are irrelevant. It’s complete faith in…
