Earth is now trapping an ‘unprecedented’ amount of heat, NASA says

New research shows that the amount of heat the planet traps has roughly doubled since 2005, contributing to more rapidly warming oceans, air and land.

The amount of heat Earth traps has roughly doubled since 2005, contributing to more rapidly warming oceans, air and land, according to new research from NASA and the National Oceanic and Atmospheric Administration.

“The magnitude of the increase is unprecedented,” said Norman Loeb, a NASA scientist and lead author of the study, which was published this week in the journal Geophysical Research Letters. “The Earth is warming faster than expected.”

Using satellite data, researchers measured what is known as Earth’s energy imbalance — the difference between how much energy the planet absorbs from the sun, and how much it’s able to shed, or radiate back out into space.

When there is a positive imbalance — Earth absorbing more heat than it is losing — it is a first step toward global warming, said Stuart Evans, a climate scientist at the University at Buffalo. “It’s a sign the Earth is gaining energy.”

Dangerous new hot zones are spreading around the world

That imbalance roughly doubled between 2005 and 2019, the study found. “It is a massive amount of energy,” said Gregory Johnson, an oceanographer for NOAA’s Pacific Marine Environmental Laboratory and co-author of the study. Johnson said the energy increase is equivalent to four detonations per second of the atomic bomb dropped on Hiroshima, or every person on Earth using 20 electric tea kettles at once. “It’s such a hard number to get your mind around.”

The Earth takes in about 240 watts per square meter of energy from the sun. At the beginning of the study period, in 2005, it was radiating back out about 239.5 of those watts — creating a positive imbalance of about half a watt. By the end, in 2019, that gap had nearly doubled to about 1 full watt per square meter.

Oceans absorb most of that heat, about 90 percent. When researchers compared satellite data to temperature readings from a system of ocean sensors, they found a similar pattern. The agreement between the data sets surpassed expectations, Loeb said, calling it the “nail in the coffin” for the imbalance results.

“The fact that they used two different observational approaches and came up with the same trends is pretty remarkable,” said Elizabeth Maroon, a climatologist at the University of Wisconsin at Madison unaffiliated with the study. “It lends a lot of confidence to the findings.”

2020 rivals hottest year on record, pushing Earth closer to a critical climate threshold

The biggest outstanding question is what is driving the acceleration.

The study points to decreases in cloud cover and sea ice, which reflect solar energy back into space, and an increase in greenhouse gases emitted by humans, such as methane and carbon dioxide, as well as water vapor, which trap more heat in the Earth, as factors in the imbalance. But it is difficult to discern human-induced changes from cyclical variations in the climate, the researches said.

“They are all kind of blended together,” said Loeb, who added that further research is needed to determine the factors.

The period studied overlapped with fluctuations in the climate that may have played a significant role in the acceleration, including a strong El Niño event from 2014 to 2016, which led to unusually warm waters. The Pacific Decadal Oscillation is a longer-term, El Niño-like fluctuation, and around 2014 that also switched from a “cool” phase to a “warm” phase.

But, Johnson says, that doesn’t let humans off the hook. “We’re responsible for some of it,” he said. It’s just unclear how much.

El Niño is dead, leaving behind legacy of a heated planet, devastated corals and monster storms

Kevin Trenberth, a distinguished scholar at the National Center of Atmospheric Research, said the results of the study aren’t particularly surprising given these climactic variations. But 15 years is not enough time to establish a trend, he said.

“Certainly you’d like to see another 10 years or something like that to see how this behaves,” he said. “The question is: Will this continue?”

That too is unclear, Johnson said. The imbalance could shrink in some years compared to others, he said, but the general trajectory appears to be upward, especially if the Pacific Decadal Oscillation stays in a warm phase.

“The longer we observe it,” he said, “the more certain we become of the trend.”

Tracking Earth’s energy imbalance will also help scientists better understand climate change, Johnson said. Other common metrics, such as air temperature, only catch a fraction of the effect of the sun’s heat. The imbalance, he said, measures “the full amount of heat that goes into the climate system.”

Regardless of the magnitude or reasons for the accelerated imbalance, the fact that it is positive is crucial, said Trenberth. “It’s the sign that matters here,” he said. “The fact that it’s positive means that global heating is happening.”

That extra heat, especially in the oceans, will mean more intense hurricanes and marine heat waves.

“I hope the heating doesn’t keep going at this clip,” Loeb said. “It’s not good news.”

Biden reappoints a top climate scientist who was removed by Trump.

By Christopher Flavelle

May 19, 2021

The Biden administration has reappointed the scientist responsible for the National Climate Assessment, the federal government’s premier contribution to climate knowledge, after he was removed from his post last year by President Donald J. Trump.

The removal of the scientist, Michael Kuperberg, was part of an effort in the final months of the Trump administration to thwart the climate assessment, which compiles the work of hundreds of scientists and helps shape regulations.

Dr. Kuperberg was replaced last November by David Legates, an academic who had previously worked closely with climate change denial groups. Just days before Mr. Trump left office, Dr. Legates posted a series of debunked scientific reports bearing the logo of the executive office of the president.

The Trump administration also removed the chief scientist at the National Oceanic and Atmospheric Administration, which helps coordinate the climate assessment. And it removed a third scientist involved in the previous version of the climate assessment after she resisted changes sought by the administration.

The reappointment of Dr. Kuperberg, whose title is executive director of the U.S. Global Change Research Program, follows the Biden administration’s creation this month of a Scientific Integrity Task Force, which White House officials have said will “review lapses of scientific integrity and ways to remedy them.”

In a statement, Dr. Kuperberg said he looked forward to helping his office “deliver nonpartisan, science-based results” to guide climate policy.

President Biden is fixing Fucktard Trump's mistakes. Trump belongs in prison.

The Washington Post

April 28, 2021

The Senate voted Wednesday to restore an Obama-era regulation that imposed limits on methane leaks from oil and gas operations.

The move marks both the first major congressional rebuke of former president Donald Trump’s environmental policies, and a step forward for the Biden administration’s ambitious climate agenda.

“We have to stop lighting the matches of methane pollution,” Sen. Edward J. Markey (D-Mass.), one of the bill’s sponsors, said at a news conference Wednesday morning.

The vote is also the first time Democrats have used the 1996 Congressional Review Act to reverse a federal regulation.

The measure cleared the divided Senate by a 52 to 42 vote. It is expected to easily pass the House and would then head to President Biden’s desk.

Biden has called limiting emissions of methane — a powerful greenhouse gas that when released without being burned has more than 80 times the climate impact of carbon dioxide — key to his pledge to cut U.S. greenhouse gas emissions by at least 50 percent by the end of the decade.

“This is a really encouraging step because methane is such an important greenhouse gas to reduce,” Drew Shindell, an earth science professor at Duke University, said of Wednesday’s vote. “It sends a signal that the administration is serious about this.”

In 2016, the Environmental Protection Agency adopted a rule requiring oil and gas companies to curb methane leaks and emissions from their operations. Late last summer, the Trump administration undid it.

The Senate vote is a step toward undoing that reversal.

If enacted, the measure would restore requirements on companies to check every six months for methane leaks from pipelines, storage tanks and other equipment installed after 2015 — and plug any leak within 30 days after it is detected.

Swift action to cut methane emissions could slow Earth’s warming by 30 percent, study finds

The Congressional Review Act gives lawmakers the power to nullify any regulation within 60 days of enactment and dictates that once a regulation has been revoked, no new “substantially the same” regulation can be adopted. Requiring only a simple majority vote, it is the swiftest way to overturn an existing federal rule. Otherwise, it would take at least a year, if not longer, for an agency to rewrite it.

Before Trump took office, the CRA had been successfully used only once, to overturn a Clinton administration ergonomics rule in 2001. Republicans used the law more than a dozen times to overturn Obama administration rules in 2017, including one aimed at blocking coal-mining operations from dumping waste into nearby waterways and another requiring that oil, gas and mining companies divulge more information to the Securities and Exchange Commission about the payments they make to foreign governments.

Speaking to reporters Wednesday, Sen. Angus King (I-Maine) said the vote amounts to “a repeal of a repeal,” which would effectively restore the original EPA rule.

Senate Majority Leader Charles E. Schumer (D-N.Y.) added, “We can undo that damage and undo it quickly.”

In recent years, methane emissions have been on a troubling upward spike. The National Oceanic and Atmospheric Administration reported this month that levels showed a “significant jump” in 2020, marking “the largest annual increase recorded since systematic measurements began in 1983.”

“It’s moving really rapidly in the wrong direction,” Shindell said. He is among an international group of scientists that found as part of a forthcoming United Nations assessment that “reducing human-caused methane emissions is one of the most cost-effective strategies to rapidly reduce the rate of warming” and meet the world’s climate targets.

The good news, he added, is that “we can do a lot on methane with existing technologies.”

A full-scale push using existing technology could cut methane emissions in half by 2030, according to a study published in the journal Environmental Research Letters. Such reductions could have a crucial effect on the global effort to limit warming to below 2 degrees Celsius (3.6 Fahrenheit) compared with preindustrial levels — a central aim of the Paris climate accord.

But some Republicans say that restoring the old rule is unnecessary. “The market is pushing the industry to lower its methane emissions,” Sen. Shelley Moore Capito (R-W.Va.) said during debate on the measure Wednesday. “The resolution we have in front of us today is nothing more than a public posturing.”

Biden has targeted 100 of Trump’s energy and environmental policies since taking office, according to a Washington Post analysis, and has reversed 28 of them so far. Most of these were not regulations, however, but agency policies or executive orders. In some instances, recent federal court rulings have nullified Trump-era rules.

Tracking Biden’s environmental actions

Many in the oil and gas industry have backed the effort to restore the Obama-era rule. Major companies such as BP and Royal Dutch Shell have endorsed it, along with some of the industry’s trade associations.

“Regulating methane emissions is essential to preventing leaks throughout the industry and protecting the environment,” Mary Streett, BP’s senior vice president for U.S. advocacy, said in a statement.

Such level of industry support may not exist on other climate initiatives. Still, Schumer said he sees Wednesday’s vote as the start of a broader legislative push on climate and a move that can help achieve Biden’s climate goals.

“It is one of the first things we’ve done to fight global warming,” Schumer said. “It will certainly not be the last.”

Fucktard Trump did everything he could to destroy the environment. What a stupid fucking asshole.

The president also announced the country was on track to reach 200 million doses administered by the week's end. The protective benefits of the Johnson & Johnson coronavirus vaccine outweigh the remote risk of blot clots, according to the European Medicines Agency. The agency, which evaluates medical products for the European Union, said Tuesday that the J&J vaccine should carry a warning label but its use does not require additional restrictions. U.S. regulators are expected to offer their guidance for this vaccine as soon as Friday.  With most of its adult populations vaccinated, including 90 percent of people age 50 and up, Israel is reopening. Restaurants, bars and beaches are busy again. Although its population can breathe a little easier, health officials note the pandemic is not yet over. Cases remain high among the 5 million Palestinians living in West Bank and Gaza, where Israel has not provided vaccine doses on a major scale.  And another Pacific island is easing its restrictions, too: Hawaii is simplifying travel rules beginning next month by allowing vaccinated state residents to travel between islands without needing a negative test. Hawaii officials said vaccine exemptions for out-of-state travelers would begin later this summer, but did not give a date. Israel isn't the only country enjoying the resumption of social life. New Zealand and Australia's dual-country travel bubble officially began this week when a plane from Australia landed in New Zealand, without any of the passengers having to quarantine.

It seems like all the data has suggested if you get it, the chances of which are slim, you will not get a serious case or be hospitalized.

But rarely in life, and in medicine in particular, are the risks zero. There's still a chance of getting sick, which you might personally be willing to take. Weighing the pros and cons, it might feel like you're ready to get back to normal once you're fully vaccinated. Here's the problem, though. We still have a lot of people in the United States (and the world) who have not yet received the vaccine. They fall into three categories: 1) the people who are refusing to get one; 2) the people still waiting in line or who are scheduled in the future; and 3) the immunocompromised people whose doctors have advised them not to get the shot, or for whom the shot is not working. Focus on those last two categories. As long as there's still a significant number of unvaccinated among us, our “vaccinated” choices will affect them. You might decide that you'll take the small risk of cold-like symptoms (or a symptomless infection), but if you do get it you can spread it to others, including, for example, strangers at the grocery store who haven't had the vaccine because they are immunocompromised. Double whammy: they can't get the shot yet and they are at higher risk of a life-threatening bout of covid. That is just one of the things public health experts are thinking about right now, and why they haven't said “once you get the vaccine, you're free.” Because with viruses, it's never just about us. We need all the healthy folks to get shots, so the people who can't will still be protected by the “herd” of immune people around them. That's when we can ease up on the concern.  Until then, we should take the standard precautions like wearing masks and social distancing.   Today’s top reads Find more stories, analysis and op-eds about the pandemic on our coronavirus page.

As Locusts Swarmed East Africa, This Tech Helped Squash Them

A hastily formed crowdsourcing operation to contain the insects in Kenya, Ethiopia and Somalia could help manage climate-related disasters everywhere.

By Rachel Nuwer

April 8, 2021

Melodine Jeptoo will never forget the first time she saw a locust swarm. Moving like a dark cloud, the insects blotted out the sky and pelted her like hail.

“When they’re flying, they really hit you hard,” said Ms. Jeptoo, who lives in Kenya and works with PlantVillage, a nonprofit group that uses technology to help farmers adapt to climate change.

In 2020, billions of the insects descended on East African countries that had not seen locusts in decades, fueled by unusual weather connected to climate change. Kenya had last dealt with a plague of this scale more than 70 years ago; Ethiopia and Somalia, more than 30 years ago. Nineteen million farmers and herders across these three countries, which bore the brunt of the damage, saw their livelihoods severely affected.

“People were operating in the dark, running around with their heads cut off in a panic,” said Keith Cressman, a senior locust forecasting officer at the United Nations Food and Agriculture Organization. “They hadn’t faced something of this magnitude since the early 1950s.”

But as bad as 2020’s swarms were, they and their offspring could have caused much worse damage. While the weather has helped slow the insects’ reproduction, the success, Mr. Cressman said, has primarily resulted from a technology-driven anti-locust operation that hastily formed in the chaotic months following the insects’ arrival to East Africa. This groundbreaking approach proved so effective at clamping down on the winged invaders in some places that some experts say it could transform management of other natural disasters around the world.

“We’d better not let this crisis go to waste,” said David Hughes, an entomologist at Penn State University. “We should use this lesson as a way not just to be adapted to the next locust crisis, but to climate change, generally.”

Desert locusts are the Dr. Jekylls and Mr. Hydes of the insect world. Normally, the grasshopper-like plant eaters spend their time living solitarily across the deserts of North Africa, Southwest Asia and the Middle East. But when rains arrive, they change from a muted brown into a fiery yellow and become gregarious, forming groups of more than 15 million insects per square mile. Such a swarm can consume the equivalent amount of food in a single day as more than 13,000 people.

The locust plague that hit East Africa in 2020 was two years in the making. In 2018, two major cyclones dumped rain in a remote area of Saudi Arabia, leading to an 8,000-fold increase in desert locust numbers. By mid-2019, winds had pushed the insects into the Horn of Africa, where a wet autumn further boosted their population. An unusual cyclone in Somalia in early December finally tipped the situation into a true emergency.

“Ten years ago, there would have been between zero and one cyclones coming off the Indian Ocean,” Dr. Hughes said. “Now there’s eight to 12 per year — a consequence of climate change.”

Countries like Sudan and Eritrea that regularly deal with small, seasonal swarms have teams of locust trackers who are trained to find the insects and recognize which life cycle stage they are in. They use a tablet-based program to transmit locust data by satellite to national and international authorities so experts can design appropriate control strategies.

But people outside of those frontline locust nations who may want to start using this system today would encounter a typical technology problem: The version of the tablets that the locust-tracking program was written for is no longer manufactured, and newer tablets are not compatible with the software. And even if the hardware were available, in 2020, East Africa lacked experts who could identify locusts.

“We’d never had a dress rehearsal for the real thing,” said Alphonse Owuor, a United Nations Food and Agriculture Organization specialist in Somalia. “We had people who were very familiar with locusts in theory, but who didn’t have the experience or equipment required to carry out this massive operation.”

With swarms suddenly covering an area of Kenya larger than New Jersey, officials were tasked with creating a locust-combating operation virtually from scratch. Collecting dependable, detailed data about locusts was the first crucial step.

“Saying ‘Oh, there’s locusts in northern Kenya’ doesn’t help at all,” Mr. Cressman said. “We need longitude and latitude coordinates in real time.”

Rather than try to rewrite the locust-tracking software for newer tablets, Mr. Cressman thought it would be more efficient to create a simple smartphone app that would allow anyone to collect data like an expert. He reached out to Dr. Hughes, who had already created a similar mobile tool with the Food and Agriculture Organization to track a devastating crop pest, the fall armyworm, through PlantVillage, which he founded.

PlantVillage’s app uses artificial intelligence and machine learning to help farmers in 60 countries, primarily in Africa, diagnose problems in their fields. Borrowing from this blueprint, Dr. Hughes and his colleagues completed the new app, eLocust3m, in just a month.

Unlike the previous tablet-based program, anyone with a smartphone can use eLocust3m. The app presents photos of locusts at different stages of their life cycles, which helps users diagnose what they see in the field. GPS coordinates are automatically recorded and algorithms double check photos submitted with each entry. Garmin International also helped with another program that worked on satellite-transmitting devices.

“The app is really easy to use,” said Ms. Jeptoo of PlantVillage. Last year, she recruited and trained locust trackers in four hard-hit Kenyan regions. “We had scouts who were 40- to 50-year-old elders, and even they were able to use it.”

In the last year, more than 240,000 locust records have poured in from East Africa, collected by PlantVillage scouts, government-trained personnel and citizens. But that was only the first step. Countries next needed to act on the data in a systematic way to quash locusts. In the first few months, however, officials were strategizing “on the back of envelopes,” Mr. Cressman said, and the entire region had just four planes for spraying pesticides.

When Batian Craig, director of 51 Degrees, a security and logistics company focused on protecting wildlife, saw Mr. Cressman quoted in a news story about locusts, he realized he could help.

Mr. Craig and his colleagues, who are headquartered at Lewa Wildlife Conservancy in Central Kenya, conduct regular anti-poaching aerial surveys that could be repurposed to seek out and destroy locust swarms. They also closely communicate with rural communities affected by the insects.

Additionally, 51 Degrees uses a free program called EarthRanger. Created by Vulcan, a Seattle-based philanthropic company originally co-founded by Paul Allen of Microsoft and his sister Jody Allen, EarthRanger compiles and analyzes geographic data ranging from rhino and ranger locations to sensor data and remote imagery.

Engineers at Vulcan agreed to customize a version of EarthRanger for locusts, integrating data from the eLocust programs and the computer loggers on aerial pesticide sprayers.

Lewa Conservancy quickly became the headquarters for aerial survey and control across the region. By June 2020, these efforts were paying off. Locusts were prevented from spilling into Africa’s Sahel region and west to Senegal.

“If we didn’t stop them, the locusts would have reached Chad, Niger, Mali and Mauritania,” said Cyril Ferrand, leader of the F.A.O.’s Eastern Africa resilience team. “We were able to prevent a much bigger catastrophe.”

The progeny of the 2020 swarms continue to cause damage across East Africa. But now, countries are better able to combat them — equipped with the new technology, 28 aircraft and thousands of trained government locust trackers. In February alone, locust-patrolling pilots in Kenya, Ethiopia and Somalia flew the equivalent of three times the circumference of the globe. They sprayed swarms before they had time to mature, stopping the insects from multiplying and spreading into Uganda and South Sudan, as they did last year.

“The situation is still very, very serious,” Mr. Cressman said. “But if you compare now to a year ago, the countries are a thousand times more prepared.”

Since February 2020, the F.A.O. estimates that this effort in East Africa has averted the loss of agricultural products with a commercial value of $1.5 billion — saving the livelihoods of 34 million people.

“These are big data for a region that’s already very fragile,” Mr. Ferrand said.

The new approach could yield even greater results in tracking, combating and even averting future disasters. Dr. Hughes is now working with experts from the National Oceanic and Atmospheric Administration and the Massachusetts Institute of Technology to use locust reports to build models that will predict future plagues. Such insight would allow countries to implement pre-emptive control strategies that are less environmentally damaging than pesticides.

The same approach, Dr. Hughes said, could also be used to combat other climate-related disasters, such as floods, droughts and pest outbreaks.

“Locusts show how we can crowdsource with artificial intelligence,” Dr. Hughes said. “This can be an absolute game-changer to hundreds of millions of people as we adapt to climate change.”
