Al Gore: Stop using the atmosphere as 'an open sewer

Data center efficiency must improve to save planet, says activist ex-veep


According to former US vice president and climate activist Al Gore, the world faces "a climate crisis of unprecedented proportions," and the data center industry can – and should – make a tremendous contribution towards averting climate-change disaster.

Speaking at Google's "How Green Is the Internet? Summit" at the company's Mountain View headquarters on Thursday, Gore reiterated his belief that global warming is real, and that its effects are already upon us.

Gore's presentation at the gathering, which is focused on energy efficiency in the data center, was awash with statistics but slim on deep scientific exploration of global warming and its concomitant climate change.

"It's worth remembering that on a daily basis we now put 90 million tons of global-warming pollution into the thin shell of atmosphere surrounding the planet every single day," Gore said, adding that twenty per cent of what humankind is currently pumping into the atmosphere will still be there 10,000 years from now.

"And it does obey the laws of physics," he said. "It does trap a lot of heat. Scientists have known that for more than a hundred and fifty years."

Ironically, he said, the first paper on what eventually became known as the greenhouse effect was published the same year that the first oil well was drilled in Pennsylvania. Since that well was drilled, the use of oil along with coal, gas, and other carbon-based fuels has grown to provide 85 per cent of the energy used by what he called "Earth, Inc."

The daily weather news is like "a nature hike through the The Book of Revelation," says Al Gore

He reminded the Summit attendees that although the atmosphere may appear limitless, it's actually quite a thin layer encasing the Earth. "If you could get into a Google self-driving car and drive straight upwards at normal highway speeds," he said, "it would take less than 10 minutes to get to the top of the sky."

According to Gore, "our planet is running a fever," and the effects of that extra energy is resulting in extreme weather. "When you turn on the news on any given day, he said," it's more likely than not to be a nature hike through the The Book of Revelation."

He went on to describe such recent extreme weather events as the current 500-year flood in southern Germany and fatal flooding in Prague's city center, flooding in the US states of Illinois and Missouri, storm surges in New York as a result of Hurricane Sandy that added to the $110bn in climate-related US disasters last year, recent floods in Pakistan that displaced 20 million people, and a storm in Queensland, Australia, that dropped 48 inches of rain in "24 hours or thereabouts," he said.

"We have to connect the dots between this 90 million tons per day of global-warming pollution that we're spewing into the atmosphere as if it is an open sewer," he said, "and the disruption of the climate conditions that have nurtured and made possible the flourishing of human civilization since the beginning of the first cities less than 10,000 years ago."

That's the bad news. The good news, Gore said, is that the "digital revolution and the information explosion" are providing us with "incredibly powerful tools" that can be used to solve the problem of increased global-warming pollution.

He also cited scientific and technological advances that he says are enabling a steep "cost down-curve" in green-energy technologies – solar and wind in particular – and also improved efficiencies.

He noted that after the oil crises of 1973 and 1979, predictions were made as to how fast energy-efficiency technologies would be adopted and how fast renewable-energy technologies would spread around the world. "Those predictions were not only wrong," he said, "they were way wrong."

These faster-than-expected improvements, however, face stiff opposition, Gore said, from "legacy wealthy and powerful industries" that are using their clout to derail governmental efforts to advance green technologies.

There's another problem, as well. "American democracy has been hacked," he said. "It no longer operates in the public interest – I'm sorry to tell you that if you didn't already know it. I mean, seriously, it's pitiful. It really is pitiful."

There is hope to be found, however, in what Gore characterized as "the great companies of the digital era – Google, and Apple, and Microsoft, et cetera," which he said are stepping forward to play a leadership role in green technology.

He congratulated Google for its recent investments in a Swedish wind farm and its billion-dollar investment in a "Hoover's Dam–worth" of clean power projects. The Apple board member also congratulated his own company for achieving what he said was 100 per cent clean-power support for its data centers and its headquarters – though he admitted that much more needs to be done with Apple's other properties.

Green power is all well and good, Gore said, but efficiency is key to improving the carbon footprint of data centers, which he said currently contribute 2 per cent of all global-warming pollution in the US. "And of course," he said, "that number is going to be growing very, very rapidly" as the much-vaunted "internet of things" grows.

"Here's another statistic," he said. "Within seven years there will be 50 billion intelligent devices connected to the internet." Those devices will, of course, require their own data infrastructure, pollution from data centers will increase, and efficiencies will need to increase to limit that pollution.

Those efficiencies, Gore said, will come from such efforts as more intelligent failover systems that don't require as much data center redundancy as that which is currently in use to ensure always-on services and to support surges in demand. Eliminating diesel generators as backup power sources? Another must-do.

Globally, Gore said, data centers currently consume 30 billion watts of electricity, and with the increase in the number of data centers for cloud usage and the internet of things, "It's obvious that we have to make a change." ®

  • Meet Wizard Spider, the multimillion-dollar gang behind Conti, Ryuk malware
    Russia-linked crime-as-a-service crew is rich, professional – and investing in R&D

    Analysis Wizard Spider, the Russia-linked crew behind high-profile malware Conti, Ryuk and Trickbot, has grown over the past five years into a multimillion-dollar organization that has built a corporate-like operating model, a year-long study has found.

    In a technical report this week, the folks at Prodaft, which has been tracking the cybercrime gang since 2021, outlined its own findings on Wizard Spider, supplemented by info that leaked about the Conti operation in February after the crooks publicly sided with Russia during the illegal invasion of Ukraine.

    What Prodaft found was a gang sitting on assets worth hundreds of millions of dollars funneled from multiple sophisticated malware variants. Wizard Spider, we're told, runs as a business with a complex network of subgroups and teams that target specific types of software, and has associations with other well-known miscreants, including those behind REvil and Qbot (also known as Qakbot or Pinkslipbot).

  • Supreme Court urged to halt 'unconstitutional' Texas content-no-moderation law
    Everyone's entitled to a viewpoint but what's your viewpoint on what exactly is and isn't a viewpoint?

    A coalition of advocacy groups on Tuesday asked the US Supreme Court to block Texas' social media law HB 20 after the US Fifth Circuit Court of Appeals last week lifted a preliminary injunction that had kept it from taking effect.

    The Lone Star State law, which forbids large social media platforms from moderating content that's "lawful-but-awful," as advocacy group the Center for Democracy and Technology puts it, was approved last September by Governor Greg Abbott (R). It was immediately challenged in court and the judge hearing the case imposed a preliminary injunction, preventing the legislation from being enforced, on the basis that the trade groups opposing it – NetChoice and CCIA – were likely to prevail.

    But that injunction was lifted on appeal. That case continues to be litigated, but thanks to the Fifth Circuit, HB 20 can be enforced even as its constitutionality remains in dispute, hence the coalition's application [PDF] this month to the Supreme Court.

    The FBI and its friends have warned businesses of crooks scraping people's credit-card details from tampered payment pages on compromised websites.

    It's an age-old problem: someone breaks into your online store and alters the code so that as your customers enter their info, copies of their data is siphoned to fraudsters to exploit. The Feds this week have detailed one such effort that reared its head lately.

    As early as September 2020, we're told, miscreants compromised at least one American company's vulnerable website from three IP addresses: 80[.]249.207.19, 80[.]82.64.211 and 80[.]249.206.197. The intruders modified the web script TempOrders.php in an attempt to inject malicious code into the checkout.php page.
