Greenhouse Gases Now Count as Maritime Pollution

- Adam Clare Leave a comment

The International Tribunal for the Law of the Sea has ruled the greenhouse gas emissions can count towards damage to our oceans. Small island nations have praised the ruling because they are the most threatened by raising sea levels and the boiling of local waters. The ruling also shows how science can inform policy in a meaningful way because the court clearly understood how oceans absorb our emissions over time and lead to acidification and other problems.

This ruling is merely a step towards better protections of our common waters and it will only mean smoother sailing for future efforts.

What happened today was that the law and science met together in this tribunal, and both won,” said Cheryl Bazard, ambassador to the European Union of the Bahamas, one of nine Caribbean and Pacific island nations that sought the opinion.

Small island nations with scant economic power but acutely vulnerable to climate change have long felt neglected by successive global summits where pledges to cut carbon emissions have fallen far short of the minimum for limiting the worst effects of global warming.

A similar potential precedent was laid down last month, when the European Court of Human Rights agreed with plaintiffs who argued that Switzerland was violating their human rights by not doing enough to combat climate warming.

Floating Flowers Clean Pollution in Waterways

- Adam Clare

Industrial farming, golf courses, and some industries all contribute an incredible amount of nutrient runoff that enters our waterways. This influx of unexpected nutrients can cause algae blooms and otherwise damage the local ecosystem. To combat this damage from runoff a team from the Florida International University created a floating platform that allows flowers to grow while not flooding out their root systems. The flowers they have chosen to grow are ones that are in demand so they can be sold commercially to fund more floating flowers. This is a novel idea that looks promising and they are already looking to expand the project.

We floated 4-by-6-foot (1.2-by-1.8-meter) mats of inexpensive polyethylene foam called Beemats in 620-gallon (2,300-liter) outdoor test tanks that mirrored water conditions of nearby polluted waterways. Into the mats, we transplanted flower seedlings, including zinnias, sunflowers, and giant marigolds. The polluted tank water was rich in nutrients, eliminating the need for any fertilizer. As the seedlings matured into plants over 12 weeks, we tracked the tanks’ improving water quality.

Encouraged by the success of the marigolds in our tanks, we moved our trials to the nearby canals of Coral Gables and Little River. We anchored the floating platforms with 50-pound (22.7-kilogram) weights and also tied them to shore for extra stability. No alterations to the landscape were needed, making the process simple and doable.

Open Source, 3D Printed, Pollution Monitoring

- Adam Clare

Efforts to monitor pollution levels around the world aren’t new, but what is new is a system created by MIT’s Senseable City Lab that anyone can make. Called Flatburn, the system is designed to be put on a vehicle to monitor pollution levels throughout a city, which will provide more coverage than standard monitors. Flatburn can be 3D printed and assembled by people the world over so it will hopefully get more participation in the majority of the world.

The goal is for community groups or individual citizens anywhere to be able to measure local air pollution, identify its sources, and, ideally, create feedback loops with officials and stakeholders to create cleaner conditions,” says Carlo Ratti, director of MIT’s Senseable City Lab.

“We’ve been doing several pilots around the world, and we have refined a set of prototypes, with hardware, software, and protocols, to make sure the data we collect are robust from an environmental science point of view,” says Simone Mora, a research scientist at Senseable City Lab and co-author of a newly published paper detailing the scanner’s testing process. The Flatburn device is part of a larger project, known as City Scanner, using mobile devices to better understand urban life.

Make Big Oil Care by Cutting Profits

We’ve heard lots of big claims from oil companies about their commitment to sustainable energy production, but those are all words. Their actions are still to extract fossil fuels which undercut all their efforts to produce renewable energy. The simple reason oil companies are still killing the environment is profit. So to get them to actually live up to their words we need to ensure that oil makes little money. Step one should be to cut market-manipulating subsidies governments give to oil companies.

The best way to hurt oil companies in the meantime is to cut back on your use of gas. Also, remember to vote for politicians that support public transit and clean air.

In terms of electricity generated from clean energy sources, BP has made the most progress of any of the oil companies — but even then, its global renewables capacity only adds up to 2,000 megawatts, the equivalent of about two gas-fired power plants.

…

Mei Li, a co-author of the report, suggested that the ability to continue profiting from fossil fuels was the chief reason that oil companies haven’t lived up to their climate promises. Wall Street is more likely to reward quarterly profits than moves to overhaul a business over the long-term. “They do not have the incentives to force them to make a clean energy transition,” Li said.

Reducing Traffic Pollution Greatly Increases Health

It’s well known that vehicular traffic is deadly no matter where it is and how much of it exists. Even with all the evidence cities in North America put cars first with the occasional protections like bike lanes and pedestrian crossings. What we also need to talk about is the threat cars bring to our lungs.

The Canadian Association of Physicians for the Environment have released a report outlining how many health gains come from eliminating cars from our streets. Electric cars aren’t the solution because they are still only focused on single occupants and give off particulate matter when braking.

Recommendations for achieving those benefits include stronger fuel content and vehicle-type rules, restrictions on idling and the use of vegetation barriers along busy roads. Cities can also implement low-emission zones that favour electric vehicles, bicycles and public transit. Ventilation systems in buildings, which became a focus during the pandemic, can play an important role in preventing traffic-related pollutants from infiltrating indoor spaces.

But like many pollution issues of the past century, effective solutions typically require governments to motivate change.

“Problems like this just cannot be tackled at the individual level,” Dr. Green said. “If an individual is concerned about this issue, then they need to demand that their politicians take action.”
