Bill Gates is funding solar geoengineering research. Is it a viable climate change solution?

Microsoft founder Bill Gates recently invested in a drastic approach to lowering the surface temperature of the earth, solar geoengineering. Along with other individuals and 14 companies, he helps to fund the Stratospheric Controlled Perturbation Experiment (SCoPEx) at Harvard University. The study has raised a total of $16,225,000 as of August 2019. 

What is solar geoengineering?

Solar geoengineering relies on the idea that all of the heat on the earth is from the sun. Certain gasses in the atmosphere keep the heat near the planet. Gasses like carbon dioxide, in this sense, act as insulators, keeping the heat close to the earth instead of letting it escape. gasses like carbon dioxide trapping solar heat in the earth’s atmosphere too well creates the climate change trend.

From this background, two paths of dealing with climate change can be discerned. One is to reduce carbon emissions. This would decrease the amount of it that is in the atmosphere trapping solar heat. The other is to change the amount of solar heat that the earth and the surrounding atmosphere absorb initially. This is the path that solar geoengineering pursues. 

To decrease the amount of solar heat that the earth absorbs, a plane would release small particles into the stratosphere, about 50 km above the earth’s surface. These particles will reflect a portion of the sunlight, theoretically creating cooler surface temperatures. However, while many researchers have run simulations, this has never been tried in the actual atmosphere. They have not yet determined the most beneficial article to use, either.

The SCoPEx Project

Later next month, the group anticipates running its first real-world experiment. While computer simulations can be highly accurate, the environment is extremely complex. Thus, running small-scale tests is an essential step before deploying this strategy on a scale that could impact worldwide temperature.

This will involve, per the research website, using a “high-altitude balloon to lift an instrument package approximately 20 km into the atmosphere.” The machine will then release approximately 2kg of naturally occurring chemicals like calcium carbonate and sulfates into the air. The release of these chemicals will create a “perturbed air mass” approximately one kilometer long and 100 meters across. This will allow for measurement of this theoretical idea in a real-world setting. Researchers will outfit the balloon with equipment to measure “aerosol density, atmospheric chemistry, and light scattering.” After particles are released, researchers will use these pieces of equipment to measure the effectiveness of this tactic.

Ethical Issues

Such a large amount of particles would have to be dispensed that they would spread to cover the entire atmosphere. Thus, this strategy would affect all countries and people on earth. All nations would have to consent in order for this strategy to be used fairly. If the particles were released into the atmosphere without the consent of all countries, it could create tension between nations, or even incite war. 

Additionally, many condemn this idea as a lazy approach to dealing with climate change, because it does not address the ultimate cause of the crisis: pollution. Thus, solar geoengineering would have to be used continuously, constantly releasing more and more particles to reflect sunlight, if carbon emissions are not curbed. If carbon emissions continue at their current rates, geoengineering couldn’t be stopped without temperatures rising several degrees as soon as there weren’t particles in the atmosphere anymore.

Adidas sustainability initiatives

According to The Robin Report, around 65 – 75 percent of consumers under the age of 35 say that they want brands to be more sustainable; Adidas sustainability initiatives aim to do just that. Naturally, news of climate change and dangers to the environment have made major impacts on the economic arena. And consequently, increasing demand for sustainable products fosters healthy competition among companies. From sustainable fashion to sustainable foods, Adidas sustainability initiatives have shown the company’s deliberate strides towards creating a more circular economy

Adidas Sustainability Initiatives Include Fighting For Plastic-Free Oceans

In 2017, Adidas and Parley For The Oceans teamed up to tackle the plastic pollution in oceans. Their cooperation created the Adidas Parley shoes. These are sports shoes made out of plastic trash found in ocean.

In that same year, Adidas managed to sell one million shoes made out of ocean plastic. And the number of shoes sold is rising. It is not just shoes, either — consumers can purchase shirts, dresses, and pants now too. All of it is recycled from ocean plastic.

Additional to the push for recycled shoes, Adidas sustainability initiatives hope to help the company shift to totally recycled polyester by 2024. Furthermore, the company promises to keep its quality with recycled polyester.

Additionally, the Futurecraft Loop is a shoe that is 100% recyclable. Adidas will sell the new iteration of these shoes in 2021. It is clear that both Adidas and Parley For The Oceans are dedicated to making the ocean a cleaner place.

The founder of Parley has spoken out against plastic pollution, “Plastic is a design failure, just alien matter that shouldn’t be on this planet.”

Creating An Incentive to Recycle

Just a few weeks ago, Adidas sustainability initiatives took one additional stride by launching a voucher system in the UK. Specifically, the system allows consumers to give back their worn-out shoes.

In return, customers would earn up to $25 in credit toward a future purchase.

Afterwards, Adidas would resell or recycle those worn-out shoes. This develops an intrinsic value in the shoes that people own. Additionally, it teaches consumers to shop more wisely.

Adidas Sustainability Initiatives Extend Past Recycling

Five days ago, the company announced its partnership with International Space Station (ISS) U.S. National Laboratory. This multi-year partnership will pursue innovations in both technology and sustainability.

Moreover, this partnership will mark the first time that footwear innovation will be tested in space. 

Among many other efforts to communicate sustainability with its consumers, Adidas hosted its annual Run for the Oceans. During the race, which occurs on World Oceans Day on June 8th, had runners log the distance they run in one week.

For every kilometer run, Adidas donated $1 to Parley Education School. These donations aided in educating young people on how to tackle the marine problem. Not surprisingly, Adidas surpassed its goal of $1.5 million.

Summary

As consumers become more environmentally aware, so must the companies that provide for them. Adidas and Parley for the Oceans are setting an important precedent for other companies that wish to continue competing in the economic arena.

With companies like Coca-Cola adding to plastic pollution, companies have to make a change if they want continual profits.

Consequently, sustainable products are imperative if companies wish to flourish in a world driven by environmental justice. But Adidas sustainability initiatives are just the first step of many.

Climate Change Is Allowing A Deadly Virus To Kill Marine Animals

PDV is killing seals and other marine animals.

As climate change continues to melt sea ice, people, particularly in coastal regions are becoming increasingly worried about being cities going underwater in the future; but now, it appears that there is another problem: melting sea ice is also allowing a deadly virus to spread and kill marine animals. That virus is PDV, or phocine distemper virus, a deadly virus that is spreading among rapidly in the Arctic waters.

While this virus continues to infect rapid and lethal rate, the disease is causing many scientists to scratch their heads. How is it traveling so quickly? And how is climate change playing a role in its rapid spread?

What Is PDV And How Is It Impacting Marine Animals?

PDV has been notorious for infecting seal populations for the last few decades. Since 1988, it has caused multiple mass deaths within the marine animal population. At an alarming rate, tens of thousands of marine animals are falling victim to PDV.

Once isolated, the virus is now circulating in seal species across the globe. 

With the use of 15 years of data that tracked 2,530 live and 165 dead marine animals of multiple regions, scientists began searching for an explanation for PDV’s infectious trend. 

PDV Outbreaks Linked To Reduction Of Sea Ice

In a recent study published by Nature, researchers linked the viral emergence in marine animals to Arctic sea ice reduction. Offering an answer to the head-scratching situation, the authors found that the melting of ice is opening-up previously blocked pathways in the Arctic Circle. 

Throughout their experiment, the researchers focused on samples from animals living in icy habitats. These include spotted seals, bearded seals, steller sea lions, northern fur, seals, and northern sea otters.

In 2003, the scientists identified a widespread exposure to and infection of PDV in the North Pacific Ocean. Six years later in 2009, the second peak of PDV exposure had infected marine animals in connected regions.

These trends were directly related to the reduction of Arctic sea ice.

Many times, Arctic ice acts as a barrier between ocean regions. However, once melted, there is no longer a physical separation between ecosystems.

With new paths of travel, the increase of marine animal mobility leads to the transmission of PDV among sea life. As there becomes more contact between the Arctic and sub-arctic marine animals, the two regions are continuing to infect once-healthy populations.

More Than One Way Of Exposing Marine Animals To Disease

Unfortunately, there is more than one way that the melting of sea ice is introducing diseases into the environment and impacting marine animals.

Through Earth’s rising temperatures, many bodies of ice are beginning to thaw for the first time in decades. Remarkably, viruses have the ability to survive a long time in frigid environments.

Under the right conditions, previously frozen organisms have a high probability of becoming re-exposed to the environment. Despite being dormant for a long period of time, these diseases may return at a similar infectious level as before.

For example, in 2014, two scientists resurrected the largest virus ever seen. After extracting the ancient virus from a 30,000-year-old sample of ice, the disease was still infections despite centuries of lying dormant.  

Summary

Fortunately, PDV-positive marine animals lie in colder waters. As a result, sea animals in warmer regions are most likely safe from PDV.

However, scientists still believe the spread of pathogens could become more common as ice continues to melt with the increased opportunity to affect more species.

To stop this infectious trend, the obvious answer is to put a halt on melting sea ice. In order to do this, each and every population has to become educated on the causes of climate change and preventative solutions.

Instead of having to learn to adapt, let us work to ensure marine animals are able to live in the quality of life they deserve.

To Truly Be Environmentally Friendly, You Should Know What Your Clothes Are Made Of

Florian Heubrandner

Most of us want to be more environmentally friendly in our daily lives; plastic straws make us shudder, we take our reusable coffee cup everywhere and haven’t used a plastic bag since 2010. But what about fashion? How do we make the right wardrobe choices for the environment?

Since being named one of the worst polluters, the fashion industry is finding ways to become more environmentally friendly. The various production phases involve making fabrics from harmful chemicals, causing water and air pollution. Some of the large-scale industrial processes even require large amounts of water and energy. Textile waste is another big issue with tons piled into landfill sites taking centuries to biodegrade.

As a result, more brands and companies are choosing cleaner materials and opting for more ethical practices. Fiber manufacturers, who are the start of the production value chain, are also putting more effort to develop sustainable, feel-good fibers from sustainably sourced wood, a renewable and naturally biodegradable material. Top fashion brands and designers, such as Zara, H&M and Stella McCartney are now choosing sustainable fibers in selected collections.

However, there are many unfamiliar names for fabric types and deciphering the sustainable ones can be a minefield.

Knowing What Is Truly Sustainable

It’s confusing. From the origin of raw materials, sourcing process to production, there are many factors determining how sustainable a piece of garment can be.

Some materials such as polyester and nylon are widely known as not sustainable due to their synthetic nature and non-biodegradability.

However, even if the source is botanical, some production processes of the raw material may involve practices that ultimately weaken the industry’s ability to sustain future production. Take cotton for example. While it starts life as a plant and seems to be sustainable, cotton-growing is a water-intensive process and has a very large water footprint.

According to the WWF, companies use up over 20,000 liters of water to produce just 1kg of cotton, equivalent to a single T-shirt and a pair of jeans.

Viscose, also known as rayon, is another plant-based fiber. It is popular in the fashion industry as a cheaper and more durable alternative to silk. Also, the industry often considers it a sustainable alternative to cotton and polyester.

While viscose is derived from an organic origin, wood pulp from regenerative trees like eucalyptus is manufactured unsustainably. Those processes inevitably contribute to the rapid depletion of the world’s forests.

Estimates show that wood that is sourced from endangered or ancient forests makes up about 30% of viscose used in the fashion industry. Those sourcing methodologies could also pose risks to habitats and endangered species.

There Are Environmentally Friendly Alternatives

There are alternatives. As technology progresses and processes are becoming more advanced, new materials are created. For example, the Lenzing’s ECOVERO™ Viscose fibers are an alternative to common viscose.

During the production of these fibers, it is possible to recover and reuse certain chemicals. And by doing so, it is possible to reduce emissions by 50% and use half as much energy and water than the production of common viscose.

Many fashion brands have started to use eco-viscose fibers in their collections, such as Japan’s Global Work, India’s Max Fashion and Germany’s Armedangels, plus many more.

Check Before You Wreck

From now on, opt for garments made from sustainable or recycled fibers, organic cotton, hemp, and linen with natural dyes. Also, armed with knowledge on common viscose and its issues, you can look for items made from eco-viscose fibers instead.

Bear in mind that some natural materials such as cotton and wool might still have their own ethical issues around environmental sustainability. For instance, those concerns can include labor rights and animal welfare.

To tackle those concerns, more brands and retailers are being more transparent about their supply chains. Specifically, 70 out of 200 major fashion brands published a list of their first-tier manufacturers.

This is an encouraging step towards a more transparent supply chain and materials that are traceable back to their roots. As the call for improved transparency across the fashion industry is stronger than ever, supply chain openness will soon be the norm and definitely something to be proud of. And our own purchase decisions will become more informed and more ethical.
