With climate-changing emissions still inching higher — and resulting threats from extreme weather surging — sucking greenhouse gases out of the atmosphere must become an urgent priority, backers of “carbon removal” efforts say.
“The math is quite simple,” Manish Bapna, executive vice president of the Washington-based World Resources Institute, told a panel discussion on the fledgling approach this week.
If the world overshoots the temperature goals set in the 2015 Paris Agreement on climate change, as looks increasingly likely, “carbon removal gets us back on track,” he said.
“The first imperative is to reduce emissions as quickly and deeply as possible,” Bapna said. “But there is now a second imperative… to remove carbon dioxide from the atmosphere at a large scale.”
Proposals to suck carbon out of the atmosphere range from planting many more trees, which absorb carbon dioxide to grow, to installing devices that capture carbon directly from the air.
Changing farming practices to store more carbon in soils, or producing energy by growing trees or crops, burning them and pumping underground the carbon released also could play a role, scientists say.
Interest in carbon removal technologies is growing, not least because countries from Britain to the United States have included some of them in their plans to curb climate change.
They also feature in a report, due out next month, by the world’s leading climate scientists, who say governments may have to find ways to extract vast amounts of carbon from the air if warming overshoots the lower Paris pact limit of 1.5 degrees Celsius (2.7 Fahrenheit). That overshoot is expected to happen by about 2040, according to a draft copy of the report.
“Carbon removal is really about creating options,” said Kelly Levin, a senior associate at the World Resources Institute. “If you fast forward 20 or 30 years, we want to keep options open.”
The surging scale of losses to extreme weather — including the storms that smashed into the eastern United States and the Philippines this month — means more people now believe climate change needs to be curbed, said Klaus Lackner, director of the U.S.-based Center for Negative Carbon Emissions.
“I believe we are at a turning point where people are starting to see the problem needs to be solved,” said Lackner, a proponent of technology to capture carbon from the air.
Right now, the costs of carbon removal may be too high but as climate impacts worsen “eventually it will hurt, and then we will pay whatever it takes,” he predicted.
“Show me technologies that didn’t get six times cheaper in a decade when they were actually used,” he added.
Carbon removal faces many other challenges including low government spending, competition for land, and a need to move faster than finance and technology may allow, experts admitted.
For instance, capturing carbon dioxide directly from the air, while possible, also requires a lot of energy, said James Mulligan, a World Resources Institute researcher on carbon removal.
Capturing just 15 percent of U.S. annual emissions would use 7 percent of projected U.S. energy production in 2050, he said.
Avoiding the worst
Farming differently to store more carbon in soils, by comparison, could be cheaper and provide extra benefits, boosting harvests, water conservation and wildlife habitats, said Betsy Taylor, president of consulting firm Breakthrough Strategies and Solutions.
“This pathway is the most affordable, technologically ready and it is a no-regrets option,” particularly as about a third of the world’s soils are now considered degraded, she said.
Experimenting with carbon removal deserves “a newfound sense of urgency” not least because more intrusive “geoengineering” ideas, such as blocking some of the sun’s rays from reaching the planet, are “coming down the pike,” she said.
But getting millions of farmers and ranchers to alter how they work would require significant investment — and monitoring carbon reductions from soil use remains an inexact science, experts admitted.
Most carbon removal technologies would get the world only a fraction of the way to solving its climate problem, they said — and the prospect of having the technologies available might be seized as an excuse to stall action to cut emissions.

“We need to be clear-eyed about the challenges,” Mulligan said.
The key, said Levin of the World Resources Institute, is ensuring both emissions cuts and carbon removal efforts move ahead fast enough to ward off the worst anticipated impacts of climate change, from worsening hunger to extreme heatwaves.
“If you look at the science, we have to pull out all the stops on mitigation and carbon removal at a scale that is completely unprecedented,” she said. (VOA)
Gone are those days when people, sports enthusiasts, and governments lined up to host the Olympics. Hosting the Olympics, once seemed to be an immensely prideful event, but it has now transformed into an economic burden. Host cities grapple with a plethora of problems which mainly include construction delays, cost overruns, security issues, and environmental concerns.
The ongoing Covid-19 pandemic has more or less aggravated the problems. The Winter Olympic Games are scheduled for 2022 in Bejing, China. Furthermore, Paris and Los Angeles have been recently nominated as the hosts for the 2024 and 2028 Olympics Games respectively. Both cities have held the Games on two occasions previously, with Los Angeles hosting as recently as 1984. Simply submitting a bid to the International Olympics Committee (IOC) costs up to millions of dollars. Host cities typically have to spend $50 million to $100 million in fees to a slew of consultancy agencies, event management companies, etc.
Hosting the Olympics is more costly than the bidding process. For instance, London spent $14.6 billion for hosting the Games in 2012. On the other side, Beijing spent a lavish $42 billion for the Games in 2008. Meanwhile, the Russians spent $51 billion dollars on the 2014 Sochi Winter Olympics. Making, it the costliest Olympic Games in the history of the Olympics.
Governments of host cities and bid teams love to brag about the legacy of hosting the Games. But the hidden costs of such a massive project is too evident to hide. Such megaprojects require additional employment, as well as subsequent improvement of the pre-existing facilities and public infrastructure. Most of these projects are fraught with costs overruns, shoddy work and a lack of long term vision.
According to a study conducted at the prestigious Oxford University In England, by Danish geographer Bent Flyvbjerg and American journalist Allison Stewart, which looked into the individual economic parameters of hosting the Summer Olympic Games between 1960 and 2012. The findings were astonishing, they found out that the Olympic Games overrun the initial cost estimate with 100 per cent consistency. No other megaproject is this consistent regarding cost overruns.
Athens, in particular, seems to have been the tipping point. The city pridefully hosted the Games in 2004, which ended up costing them €9 billion (a whopping $11 billion at today's exchange rate). The offset of the Games was in disguise the onset of Greece's tumultuous years. The country now is in total disarray, with sky-high unemployment rates, failing economic apparatus, record levels of homelessness, all among the grandiose venues built for the Games.
The conclusion is simple, hosting the Olympics is an extravagant affair. If not planned properly, it tends to result in a severe economic crisis for the host city. If the host city lacks facilities and public infrastructure to support the excess crowds pouring in, not hosting the Olympics may be the best option.
Indian wrestler Ravi Kumar (57kg) and Deepak Punia (86kg) enjoyed fruitful outings at the Tokyo Olympic Games as they secured semifinal berths in their respective weight categories at the Makuhari Messe on Wednesday.
On the opening day of the wrestling competition, Ravi Kumar defeated Bulgaria's Georgi Vangelov 14-4 on technical superiority to reach the last-four in the men's 57kg category, while compatriot Deepak Punia overcame China's Zushen Lin 6-3 on points to advance to the semifinals.
Ravi Kumar will take on Nurislam Sanayev of Kazakhstan in the last-four, while Punia will be up against David Morris Taylor of the USA.
Earlier, Ravi Kumar had won his opening-round bout by technical superiority against Colombia's Oscar Tigreros to secure a quarterfinal spot. Competing in the Round-of-16 bout against the Colombian wrestler, the 23-year-old Ravi Kumar, who is making his Olympic debut, showed no nerves as he dominated the bout to win by technical superiority (13-2).
Ravi Kumar landed attack after attack and went 13-2 up, winning the bout by technical superiority with minutes to spare. In wrestling, building up a 10-point lead over the opponent results in a victory by technical superiority.
India's 86kg freestyle wrestler Deepak Punia showed no signs of the niggle that had forced him to pull out of the Poland Open Ranking Series in Warsaw in June, as he defeated Nigeria's Ekerekeme Agiomor on technical superiority to secure a quarterfinal berth.
He got his Olympic campaign to a fine start as he was in control from the start of the bout and hardly ever allowed his Nigerian opponent any room to maneuver his moves, finally winning with a 12-1 on technical superiority.
Punia, who had also suffered an elbow injury just before the Games, was slow at the start but came into his own as the bout progressed, inflicting takedowns at regular intervals to earn points.
The Indian wrestler eased into a 4-1 lead at the break and extended his lead comfortably in the second period.
Punia, the silver medallist from the 2019 world wrestling championships, then set up a clash with China's Lin Zushen in the quarterfinals and defeated him 6-3.
Indian origin girls -- New Jersey-based Natasha Peri (11) and Dubai-based Priyamvada Deshmukh (12) -- have been named in the worlds "brightest" students list based on results of above-grade-level testing of 19,000 students across 84 countries, according to Johns Hopkins Center for Talented Youth (CTY), a part of Johns Hopkins University in Baltimore, Maryland.
"Peri, a student at Thelma L. Sandmeier Elementary School, was honored for exceptional performance on the SAT, ACT, or similar assessment is taken as part of the CTY Talent Search," said a statement from the CTY.
Deshmukh, a student of GEMS Modern Academy, Dubai, has been honored for her exceptional performance on the SCAT assessment taken as part of the CTY Talent Search, a university statement said.
She was one of nearly 19,000 students from 84 countries who joined CTY in the 2019-21 Talent Search years. CTY uses above-grade-level testing to identify advanced students from around the world and provide a clear picture of their true academic abilities.
Peri took the Johns Hopkins Talent Search test in Spring 2021 when she was in Grade 5. Her results in the verbal and quantitative sections leveled with the 90th percentile of advanced Grade 8 performance.
"This motivates me to do more," she said, adding that doodling and reading J.R.R Tolkien's novels may have worked for her.
Deshmukh took the Johns Hopkins Talent Search test in Spring 2020 when she was still in Grade 6. Her results in the verbal sections leveled with the advanced Grade 10 performance. She made the cut for Johns Hopkins CTY 'High Honors Awards'.
Due to the Covid19, induced delay in Global logistics support, she finally received her much-awaited "High Honors" pin this week, which she lovingly kept in front of her Grandparents photograph as a tribute to her roots.
The delay in officially getting the certificates did not stop her from attending the summer program at John Hopkins University's CTY in English literature where she studied the confluence of Art and Science in literary writing and completed the course scoring 'A' Grade.
She followed up with top-scoring the second level of Asset Talent Examination which also qualified her for the summer program at Northwestern University this year, where she is learning about world-building in fiction writing this year.
Her elder brother was among the first UAE students to have cleared the Duke University TIP (Talent Identification Programme) when he was in Class 8.
Her parents joke that it's nothing but routine sibling rivalry that she wanted to achieve the same, just a year ahead of her brother. Even though she loves Physics and Computer Science as subjects, unlike her elder brother (who is Chancellor's Scholarship holder student of Astro Physics at the University of Massachusetts), Deshmukh wants to pursue humanities and literature when she goes to college five years down the lane.
As part of Johns Hopkins policy, granular information is not broken down by age or race.
Likewise, it is left to the guardian to disclose the prodigy's name. Within the US, awardees come from all 50 US states.
"We are thrilled to celebrate these students," said Virginia Roach, CTY's executive director.
"In a year that was anything but ordinary, their love of learning shined through, and we are excited to help cultivate their growth as scholars and citizens throughout high school, college, and beyond," Roach added.
The quantitative section of the Johns Hopkins CTY test measures the ability to see relationships between quantities expressed in mathematical terms, the verbal section measures understanding of the meaning of words and the relationships between them.
