The Climate Change Deniers are Done

- Adam Clare

Climate change deniers have clearly set back human progress and delayed us in reducing emissions, obviously that’s no good. What is good is that they barely exist anymore. The science has always been done properly around climate change and people are living the chaos that climate change has caused; it’s as impossible to deny as a round Earth. Conversations are no longer hijacked by people who deny climate reality, and that’s a good thing.

How do we know this? Some researchers set out to determine how present climate change denialism was online only to find it declining. A really need potential spinoff from this research is how to look into other aspects of people denying science and how to engage them to better understand reality.

In a study out this week in the journal Nature Scientific Reports, researchers found that outright denying the science is going out of fashion. Today, only about 10 percent of arguments from conservative think tanks in North America challenge the scientific consensus around global warming or question models and data. (For the record, 99.9 percent of scientists agree that human activity is heating up the planet.) Instead, the most common arguments are that scientists and climate advocates simply can’t be trusted, and that proposed solutions won’t work.

It took Cook and his team about five years to create a machine learning model that was able to reliably detect real-life climate misinformation claims. “Misinformation is messy and doing content analysis is messy, because the real world is always a bit blurry,” Cook said. First, they developed a taxonomy to sort arguments into broad categories — say, “climate change isn’t bad” — narrower claims (“carbon dioxide is not a pollutant”) and even more specific points (“CO2 is food for plants!”). Then they fed common climate myths into the machine until it was able to recognize each one consistently out in the wild.

New York City Bans New Gas Connections

New buildings constructed in New York City are not permitted to connect to natural gas for any reason. This makes NYC the largest city in the USA to do so and likely marks a shift in the country for even more cities to adopt a ban on new uses of the fossil fuel. To avoid catastrophic climate change we need to keep fossil fuel in the ground and with NYC banning new buildings from using the world-destroying product it will force the construction industry to adapt.

The measure already has support from Con Edison, a utility that provides both electricity and gas to New Yorkers. The grid “is well-poised to support the transition to heating electrification,” it said in a November testimony to city council. That’s because the grid usually sees peak demand during the summer when residents blast their air conditioning, it says, and electricity use is typically lower in the winter.

“New York City is taking a massive step off fossil fuels, paving the way for the rest of the state and country to follow,” Food & Water Watch northeast region director Alex Beauchamp said in a statement today.

How Mangroves Manage Climate Change

- Adam Clare

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.

Green Your Garage

- Adam Clare

If you have a garage filled with tools and other oddities, you can easily make it a little nicer for you and the environment. The next time you do some cleaning you can think about what is clean for the rest of the environment. Of course, you’re going to want to properly dispose of pesticides as you should never use them in the first place. There are more things you can do too, like checking your tools to find out if the tools can be replaced by something with a smaller carbon footprint.

After the leaf blower, you might want to check on your lawn mower, chainsaw, snow blower, air compressor, and generator, if you have them. The gasoline engines in these pieces of equipment spew out greenhouse gases that are as concerning as the crud coming out of leaf blowers.

As for alternatives, electric or manual gear is the way to go. There are plenty of lists online that can guide you towards the best push mower, battery-powered chainsaw, electric snow blower, air compressor, or electric generator. My town has been having a craze for robotic lawn mowers recently. They don’t work on hills, but if your lawn is flat, consider one of these electric models. They are mesmerizing to watch, cut the grass in a random pattern, and, bonus points, you don’t have to push them around.
