How Mangroves Manage Climate Change

Dense mangrove forests provide an ecological boost wherever they are found because they protect both land and sea species. They are really ecosystems unto themselves with nuance and each with their own history. That history can help us understand how the delicate forests will survive climate change, we know they have before and now we can understand how we can help them survive our current rapidly changing climate.

Mangroves are also gorgeous!

“The most amazing part of this study is that we were able to examine a mangrove ecosystem that has been trapped in time for more than 100,000 years,” said study co-author Octavio Aburto-Oropeza, a marine ecologist at Scripps Institution of Oceanography at UC San Diego and a Pew Marine Fellow. “There is certainly more to discover about how the many species in this ecosystem adapted throughout different environmental conditions over the past 100,000 years. Studying these past adaptations will be very important for us to better understand future conditions in a changing climate.”

Combining multiple lines of evidence, the study demonstrates that the rare and unique mangrove ecosystem of the San Pedro River is a relict—that is, organisms that have survived from an earlier period—from a past warmer world when relative sea levels were six to nine meters (20 to 30 feet) higher than at present, high enough to flood the Tabasco lowlands of Mexico and reach what today are tropical rainforests on the banks of the San Pedro River.

Carbon Capture Solutions from Students get Funding

The best thing to do to prevent climate change is to stop burning fossil fuels, until that happens we need to find ways to extract carbon from the air to reduce the speed of climate change. Of course, carbon removal needs to be powered by renewable systems themselves. The XPrize for carbon removal kicked off in February, part of that launch involved a competition for universities to apply for funding radical carbon removal ideas. The winners have been announced and the projects are looking at everything from cleaning up asbestos to making a tea out of yard waste.

The Blue Symbiosis team from Australia’s University of Tasmania is looking to tap into the natural CO2-absorbing properties of seaweed, by repurposing oil and gas rigs as regenerative farming sites. The offshore platforms provide the trunk, while the seaweed will act as the branches, according to the team. The team aims to scale up production to the point where the system can have a real impact on ocean health, with part of the seaweed to also be used in construction materials such as fire-resilient bricks, enabling the carbon being stored to be quantified.

“I researched the potential of repurposing oil and gas infrastructure to regenerative seaweed sites, which led to the conclusion that this holds real promise for both environmental and commercial reasons,” says team leader Joshua Castle. “Decommissioning oil and gas infrastructure is an emerging AU$60-billion (US$44-billion) problem for governments and industries in which they are expected to share the costs. Seaweed has the potential to deliver vast environmental benefits for ocean health – but if it can’t be scaled, significant impacts on ocean health can’t be realized.

See Through Solar Panels

The future is powered by renewables, and the more sources of electricity we have the more resilient our power grid will be. Researches at Michigan State University have created a solar film that can be applied to existing windows to generate electricity from the sun. The system is not as efficient as a standalone solar cell, but the benefits of putting the film on existing windows outweighs the inefficiency. The film is see through which means the windows look like normal windows. Imagine every window in a skyscraper generating a little amount of power or the windows on every electric car.

Back in 2017 MSU profiled Lunt’s work and explained that he and his team “pioneered the development of a transparent luminescent solar concentrator that when placed on a window creates solar energy without disrupting the view. The thin, plastic-like material can be used on buildings, car windows, cell phones or other devices with a clear surface.”

“The solar-harvesting system uses organic molecules developed by Lunt and his team to absorb invisible wavelengths of sunlight. The researchers can ‘tune’ these materials to pick up just the ultraviolet and the near-infrared wavelengths that then convert this energy into electricity,” MSU adds.

Vertical Farming and the Future of Farms

Quality farmland ensures a good harvest which benefits many, from the producers of produce to the consumers. Our cities have grown around good for sources from the sea and land, this puts pressure on the local politicians to give up arable land to developers. In Ontario, the conservative party values developers over food. What will the future of food be as we destroy soil with asphalt? Farms will have to go vertical.

Another plus of vertical farming is that pesticides aren’t even in the equation. The extremely tight control these companies exert in the farm facilities means there are few concerns about contamination and illness caused by toxic chemicals, bugs, invasive species or vermin. Regardless, as Seawell demonstrated, these companies are not taking any chances: staff and visitors are still required to wear a full body suit with shoe covers, rubber gloves and a hairnet to limit any foreign contaminants.

Vertical farming also makes it possible for communities to have almost immediate access to produce. Facilities can be built and operated close to or even with dense urban neighborhoods. Vegetables and fruits don’t need to traverse thousands of miles from farm to grocery store and risk spoiling (food waste during transit is a contributor to the 40 percent of all food in the U.S. that ends up in landfills). Even when produce survives the journey, it can lose significant nutritional value; spinach, for instance, can lose up to 90 percent of its vitamin C nutrients within a day of harvest.

Time to Break Up with Gas

One thing is certain: we need to get off of fossil fuels as fast as possible. The gas companies want to keep polluting and are paying people to promote the burning of carbon-intensive resources.Gas companies are using influencers to promote gas stoves, when everyone knows that induction stovetops are better in every way.

Because so many people are concerned about how much carbon we dump into the air, there is a burgeoning grassroots movement trying to disconnect everyone from gas consumption. The video above is one such example, and as more people understand the state of our planet more people are switching from gas to electric solutions.

Further complicating things, the gas industry has, for decades, framed itself as a “cleaner” alternative to fossil fuels like coal and oil. “We should probably discuss the name of it: ‘Natural gas.’” says Panama Bartholomy, executive director of the nonprofit Building Decarbonization Coalition in California. “It has been perhaps one of the most successful marketing campaigns that we’ve seen from a large industry to call what is really a dangerous pollutant, something natural.”
