(EARTHDAY.ORG) Carbon Dioxide Levels Reach Peak In 4 Million Years, What This Means For Climate Change

EARTHDAY.ORG


According to the National Oceanic and Atmospheric Administration (NOAA), the amount of carbon dioxide (CO2) in the Earth’s atmosphere reached 419 parts per million in May. These are the highest carbon dioxide levels in over four million years.

The last time that the atmosphere held comparable levels of CO2 was during the Pliocene period, when the Earth looked completely different from what it does today. Sea levels were 78 feet higher, temperatures were 7 degrees Fahrenheit warmer and large forests covered parts of the Arctic tundra.

What do these record CO2 emissions mean for climate change? The atmosphere acts as a heat-trapping blanket. Greenhouse gases, like CO2, keep temperatures on Earth comfortable for human survival.

However, we are emitting record amounts of CO2 into the atmosphere due to transportation, electrical generation, deforestation, agriculture and more. This excess amount of human-induced CO2 causes average temperatures to rise over time, resulting in what is known as climate change.

Dear Humans: A message from Earth to its inhabitants

Climate change is already impacting life as we know it. Rising temperatures, changing seasons, altered rainfall patterns and stronger hurricanes are but a few of its tremendous effects.

“We are adding roughly 40 billion metric tons of CO2 pollution to the atmosphere per year,” said Pieter Tans, a senior scientist with NOAA’s Global Monitoring Laboratory. “That is a mountain of carbon that we dig up out of the Earth, burn, and release into the atmosphere as CO2 – year after year. If we want to avoid catastrophic climate change, the highest priority must be to reduce CO2 pollution to zero at the earliest possible date.” 

We must also grapple with the CO2 already present in the atmosphere. Known as “legacy emissions,” this represents the CO2 that has been accumulating over the past 200 years.

Enter climate restoration. It would provide for removal and sequestration of the trillion tons of CO2 emissions previously emitted into the atmosphere. Restoration efforts could lower atmospheric carbon to pre-industrial levels.

We have the opportunity to turn a grim headline into an opportunity if we Restore Our Earth. We’re running out of time, but if we act now and act together, we can turn the tide on the climate crisis.

(The Conversation) Shipping Is Tough On The Climate And Hard To Clean Up – These Innovations Can Help Cut Emissions

Ships carry more than 80% of world trade, and they rely heavily on some of the least environmentally friendly transportation fuels available.

There are no cheap, widely available solutions that can lower the shipping industry’s planet-warming carbon emissions – in fact, shipping is considered one of the hardest industries on the planet to decarbonize – but some exciting innovations are being tested right now.

 As a professor of naval architecture and marine engineering, I work on ship propulsion and control systems, including electrification, batteries and fuel cells.

With attention focused on climate change this week as world leaders meet at the G-7 summit and negotiators discuss shipping emissions at a meeting of the U.N.‘s International Maritime Organization, let’s take a look at what’s possible and some of the fuels and technologies that are likely to define the industry’s future.

Shipping’s climate problem

Shipping is the cheapest way to move raw materials and bulk goods. That has given it both an enormous economic impact and a large carbon footprint.

The industry emits roughly 1 billion metric tons of carbon dioxide per year – nearly 3% of global emissions, according to the IMO, a specialized U.N. agency made up of 174 member nations that sets standards for the industry.

If shipping were a country, it would rank between Japan and Germany as the sixth-largest contributor to global carbon dioxide emissions. Moreover, nearly 70% of ships’ emissions occur within 250 miles (400 kilometers) of land, meaning it also has an impact on air quality, especially for port cities.


Technological innovation, in addition to policies, will be crucial for achieving low-carbon or zero-emission shipping.

Academic research institutes, government labs and companies are now experimenting with electrification; zero- or low-carbon fuels such as hydrogen, natural gas, ammonia and biofuels; and alternative power sources such as fuel cells and solar, wind and wave power. Each has its pros and cons.

Why electrifying ships matters

Just as on land, electrification is one key to cleaning up the industry’s emissions. It allows engines operating on fossil fuels to be either replaced by alternative power generation technologies, or downsized and modified for low-emissions operation. It also allows ships to connect to electric power while in port, reducing their emissions from idling.

Ship electrification and hybridization are significant trends for both commercial and military vessels. Electrifying a ship means replacing its traditional mechanical systems with electrical ones. Some fleets have already electrified propulsion and cargo handling.

Hybrid power systems, on the other hand, integrate different power-generation mechanisms, such as engines and batteries, to leverage their complementary characteristics.

I see deeper electrification and broader hybridization as a core strategy for achieving green shipping.

Tremendous opportunities also exist for improving the operation of the existing fleet – and reducing fuel use – through automation and real-time control. Advanced sensors, artificial intelligence and machine learning can help ships to “see,” “think,” and “act” better to improve efficiency and reduce emissions.

Greener fuels for ocean voyages

Shifting to cleaner and greener fuel sources will be essential for decarbonizing the shipping industry.

Most of the power plants on today’s ships are based on internal combustion engines that use cheap heavy fuel oil. Innovations in marine diesel and gas turbine engine design and treatment of exhaust gas have lowered harmful emissions. However, most of the “low-hanging fruit” has been harvested, with little room left for dramatic improvement in traditional power sources.

The focus now is on developing cleaner fuel sources and more efficient alternative power generation technologies.

Low or zero-carbon fuels, such as natural gas, ammonia and hydrogen, are predicted to be the dominant energy sources for shipping in the future.

Ammonia is easy to transport and store, and it can be used in internal combustion engines and high-temperature fuel cells. But like hydrogen, it is largely still made with fossil fuels. It’s also toxic. Both have the potential to be made with water and renewable energy using electrolysis, but that zero-carbon technology is still in the early stages and costly.

These fuels have started replacing heavy diesel fuels in some marine segments, primarily as demonstration projects and at a slower rate than needed. Cost and infrastructure remain major barriers.

Renewable energy sources, such as wind, solar and wave energy, are also promising. Integrating renewable sources as cost-effective and reliable energy solutions for oceangoing vessels is another challenge developers are working on.



Powering ships using fuel cells and batteries

Fuel cells and batteries also hold promise as alternative power generation technologies.

Through electrochemical reactions, fuel cells generate electric power in a highly efficient and clean manner, making them very attractive for transportation. Fuel cells are operated with pure hydrogen or reformed gases, except for high-temperature fuel cells that can use natural gas or ammonia as fuel.

Given the existing fuel infrastructure, most maritime fuel cell demonstration projects today have to store liquid hydrogen or use onboard systems that convert natural gas or other fuel to hydrogen-rich syngas. Infrastructure for hydrogen storage has to be developed for widespread adoption of fuel cell technology.

Battery technology is essential for electrification, even for ships with an internal combustion engine as their prime mover. It also has its own unique challenges. In addition to ensuring the batteries are safe and reliable – you don’t want a fire or power outage in the middle of the ocean – ruggedness and flexibility are necessary for powering operations such as cargo handling and tugboat operations.

Investing in the future

In 2018, the International Maritime Organization’s Marine Environment Protection Committee set targets to reduce the carbon intensity of the global fleet by at least 40% by 2030 and to cut its greenhouse gas emissions in half by 2050 from the 2008 levels. It’s expected to adopt mandatory requirements reflecting those long-term goals at its meeting June 10-17, 2021.

Those targets are important, but they leave the deadlines for action well into the future.

Countries and some shipping companies are recommending a faster transition. In early June, the governments of Denmark, Norway and the United States, along with the Global Maritime Forum and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping, announced a new Zero-Emission Shipping Mission to try to scale up and deploy new green maritime solutions faster.

The shipping giant AP Møller-Maersk has said it could support a carbon tax of $150 per ton of carbon dioxide to encourage more innovation and a faster transition, though others in the industry argue that a tax like that would nearly double the cost of bunker fuel and make freight far more expensive, with repercussions throughout the global economy.

I believe the grand vision of zero-emission shipping can be realized if the ship design and fleet operation communities work together with policymakers, the logistics industry and the broad academic and industry technical communities to find solutions.

This is an exciting time to work in the area of energy and power solutions for shipping. The technology developed today will have a transformative impact, not only on the marine industry but also on society.

(USA Bloomberg) China EV Maker Betting On Cult Status To Sell A Million Cars

Bloomberg News - Emma O’Brien

  • SAIC-GM-Wuling makes the Mini, a hit with young, female buyers
  • Company first built huge following around its small, boxy vans
WATCH: A little-known automaker in China’s southwest has been dominating the world’s largest electric car market since last July.

Since last July, a little-known automaker in China’s southwest has dominated the world’s largest electric car market, outselling bigger players and even Tesla Inc. almost every month with a tiny, bare-bones EV that starts at just $4,500.

The Hongguang Mini is the brainchild of SAIC-GM-Wuling Automobile Co., a joint venture between SAIC Motor Corp. and Guangxi Automobile Group Co., two state-backed automakers, and U.S. giant General Motors Co.

Based in the city of Liuzhou, known for its limestone mountains and river-snail soup, the company -- which has sold some 270,000 of the cars within nine months, making it the best-selling EV in China -- has even bigger ambitions for the future. It’s aiming for annual sales of 1.2 million vehicles next year, almost equal to the number of EVs churned out by China’s carmakers in 2020 combined.

It’s an eyebrow-raising target, but even before the Hongguang Mini, Wuling had a track record for producing winners in a market that’s defining the new era of driving. Set up in 2002, the Chinese-American JV built its business selling microvans: dependable sliding-door workhorses that earned the nickname ‘the bread box car’ in Mandarin, and were China’s top-selling passenger vehicle in 2017. Millions of them ply the country’s roads, used by contractors and delivery drivers alike.

The buyers of those gas-guzzling gray vans are almost exclusively male, which makes Wuling’s pivot to the Hongguang Mini -- which has a top speed of 100 kilometers (62 miles) an hour and 12-inch wheels -- all the more extraordinary. Shortly after its debut last July, the automaker realized the vehicle was gaining a following among young women, a phenomenon it leaned into with an approach that bends conventional wisdom about how cars are sold.

“Our company’s mentality is to produce whatever people need,” Wuling’s head of branding and marketing, Zhang Yiqin, said in an interview. “We keep close tabs on our users. The hurdles to electric car adoption can only be cleared when consumers find using them a comfortable thing.”

To that end, Zhang has staffed his team with employees who understand the Hongguang Mini’s customer base, which is now around two-thirds female. At 35, he jokes he’s the elder statesman of the group whose age averages around 27. Slogans like ‘Young and Eager’ are splashed across the walls of Wuling’s headquarters in Liuzhou, a city that’s embraced EVs alongside the company with 30% of all car sales electric last year, the highest rate in China, according to WAYS Information Technology.

Wuling’s success with the Hongguang Mini was driven by a targeted marketing campaign conducted almost entirely online, according to Zhang. His team often communicate with consumers directly via various social media platforms, and it was a customer’s request for more hues that saw the company come up with Hongguang Mini’s latest iteration -- the Macaron. It comes in avocado green, lemon yellow and white peach pink, with an optional solid-color roof for contrast, to mimic the vanilla butter cream that sandwiches the French meringue confections of the same name.

It’s also how they landed on one of the car’s key selling points -- besides its rock-bottom price point: Hongguang Mini drivers are able to customize their vehicles in a way that’s not possible elsewhere.

Using “stickers,” the car’s panels and body can be transformed. Some sport the Nike swoosh, some have galaxy-like outer space scenes and others cartoon characters from Hello Kitty and Doraemon. The original Hongguang Mini comes in around 20 different base colors, which can be switched up, and buyers can customize the interior as well.

Zorah Zhang (no relation) is a typical client. The 23-year-old is a fan of Hayao Miyazaki, the Japanese animator who directed My Neighbor Totoro, a fantasy film featuring a character called The Catbus, a grinning feline whose seats are covered in fur.

She’s pimped her Hongguang Mini to resemble it, spending around 15,000 yuan ($2,300) to cover the car’s interior with brown velveteen and studding the roof with lights that sparkle at night.

“A lot of my friends have the Mini, you see them everywhere in Liuzhou,” said Zhang, who lives with her parents (they drive a BMW sedan). “I love things that reflect my character. I may change the look of the car again if there’s other stuff I fancy.”

As frivolous as turning a set of wheels into a fashion accessory may seem, there’s a very real market up for grabs.

Outside of Liuzhou, EV penetration in China is still only around 6% and competition is fierce. Tesla may be the name that resonates loudest, particularly in larger cities like Beijing and Shanghai, where its first Gigafactory is located, but a host of newer, local entrants from Nio Inc. to Xpeng Inc., Li Auto Inc. and WM Motor are crowding in.

At the same time, other home-grown players like BYD Co., a carmaker long backed by Warren Buffett, are upping their EV game and international behemoths such as Volkswagen AG are plowing billions of dollars into new electric lineups.

With consumers in China overwhelmed by choice when fossil-fuel cars are added to the mix, automakers need to give motorists what they want to survive, said Jochen Siebert, managing director of consultancy JSC Automotive in Singapore.

“SAIC-GM-Wuling has to come up with new ideas all the time to attract consumers,” Siebert said. The Hongguang Mini is “a kind of accessory, which means it’s a fashion item that might go out of fashion sooner or later.”

For now, it’s a strategy that’s paying dividends for Wuling. The company, owned 50.1% by Shanghai-based SAIC, 44% by GM’s China unit and 5.9% by Guangxi Automobile, sold 1.6 million vehicles in total last year. While that was down about 4% from 2019 amid the pandemic, Wuling’s new-energy vehicle sales almost tripled to 174,000 units.

For GM -- which is doubling down on electrification and autonomous driving under Chief Executive Officer Mary Barra -- the Hongguang Mini appears to have been a boon. The carmaker saw revenue of $9.9 billion from its China auto joint ventures in first-quarter results out last month, up from $4.3 billion for the first three months of 2020. GM, which has several other partnerships in China, doesn’t break out Wuling’s revenue in its financial results.

While customer engagement has distinguished the Hongguang Mini, cost has been main driver of its blockbuster sales in a country where many find the sticker price of a Tesla Model 3, which sells for the equivalent of $39,300, beyond reach. The basic Hongguang Mini starts at $4,500, and even the new Macaron sells for under $6,000.

Wuling has been able to churn out cheap cars thanks in part to its good supply-chain management, honed with the super-popular microvans. Many of Wuling’s suppliers have also set up manufacturing bases in Liuzhou, which has helped cap costs further. It’s a model that’s being replicated by car companies in other cities and provinces across China, flattering for Wuling but challenging too as the price of rivals’ cars come down.

Multinational automakers are also eyeing off the compact EV space, with Daimler AG set to make an electric version of the Smart -- for many, the consummate tiny car -- in China with its own venture partner.

The global shortage of semiconductors is also weighing on Wuling, with the Hongguang Mini, despite being a basic EV, still requiring over 100 chips. Hongguang Mini production has been impacted by the shortfall, with output of the Macaron expected to be down around 15% in May, according to Zhang.

The hefty sales target for 2022 is the cornerstone of Wuling’s plan to maintain its market-leading momentum. After debuting a convertible Hongguang Mini at the Shanghai Auto Show in April, it’s aiming to release a mid-cycle enhancement of the vehicle later this year and is working on a two-seater EV targeted at younger men, Zhang said.

At a Wuling dealership in downtown Liuzhou, user-experience manager Li Zhengguang says there’s a four-person team focused solely on new media. They communicate with would-be customers using Douyin, as TikTok is known in China, and Little Red Book, a trusted social shopping platform popular with young women, sharing photos and videos. Li, who used to sell diamond engagement rings, says there’s not a lot of difference between jewelry and cars. Create desire for a cool product and buyers will come, he says.

Pitching the Hongguang Mini not as a cheap car but a coveted accessory in brand-conscious China is brilliant, JSC Automotive’s Siebert said.

“It’s become a hallmark of SAIC-GM-Wuling over the past 20 years to always surprise the market, and themselves,” he said. “They’ve done extremely well because they focus on the right things. On quality, when they were mainly making microvans, and now on marketing.”
