A pair of students at the University of Pennsylvania have an audacious suggestion should rising sea levels make their presence felt in Manhattan, New York. Their scheme would see the installation of waterproof canopies to the lower stories of skyscrapers. Tingwei Xu and Xie Zhang say their idea has an "irreducible integrity," thanks to the canopies' various functions which, the students say, are each of equal importance. So in addition to keeping water out, these canopies provide additional structural support against lateral forces, provide green or agricultural space, and, judging by the visualizations, provide living and working areas in their own right.  Read More

In the face of potentially catastrophic effects on global food production, some have proposed drastic solutions to counteract climate change such as reflecting sunlight away from the Earth. A new study from the Carnegie Institution for Science examining the effects of sunshade geoengineering has concluded that such an approach would be more likely to improve food security than threaten it.  Read More

Researchers claim a newly discovered molecule found in the Earth’s atmosphere holds the potential to help offset global warming by actually cooling the planet. The molecule is a Criegee biradical or Criegee intermediate, which are chemical intermediaries that are powerful oxidizers of pollutants produced by combustion, such as nitrogen dioxide and sulfur dioxide. They have the ability to naturally clean up the atmosphere by helping break down nitrogen dioxide and sulfur dioxide to form sulfate and nitrate, which ultimately leads to cloud formation that could help cool the planet.  Read More

A commonly-available, inexpensive polymer has been shown to be very effective at capturing...

In recent years, worries over global climate change caused by excess atmospheric carbon dioxide have led to a number of technologies all aimed at the same thing – capturing human-generated CO2 at the source. These have included the use of things such as edible sponges, molten salts and bacteria, to name just a few. Now, a group of scientists are claiming success with a process that has achieved “some of the highest carbon dioxide removal rates ever reported for humid air” ... and it uses a common and inexpensive polymer.  Read More

According to a recent study funded by the National Science Foundation’s Paleoclimate Program, climate change may be far less sensitive to carbon dioxide fluctuations than previously predicted.  Read More

The Climate Reality Project (formerly known as the Alliance for Climate Protection) has just kicked off its "24 Hours of Reality" live streamed event. The presentation runs 24 hours, is available live in 13 languages, and is the beginning of a worldwide campaign to present the latest information about the climate crisis and reject misinformation.  Read More

While some see carbon capture and storage as akin to sweeping CO2 emissions under the carpet, others believe it is a necessary short-term solution in the transition to a clean energy future. Last week, ground was broken on construction of the U.S.'s first large-scale industrial carbon capture and storage (ICCS) facility that aims to demonstrate that CO2 emissions can be stored permanently in deep underground rock formations.  Read More

Lab-grown meat offers significant environmental benefits over conventional meat farming te...

As a meat lover, it's been hard not to notice the rise in the price of meat at my local supermarket over the last few years. But it’s not just the cost to consumers that is a major concern; it’s the major role that livestock production plays on climate change. While cultured meat, also known as in vitro meat, lab-grown meat and even Frankenmeat, might not sound that appetizing to many meat lovers, a new study carried out by scientists from Oxford University and the University of Amsterdam says that cultured meat would provide substantial environmental benefits.  Read More

The Lilypad floating city concept is designed to house climate change refugees

With global sea levels predicted to rise significantly over the next century due to climate change, a lot of people living in low lying areas are expected to be displaced from their homes. Architect Vincent Callebaut has come up with a possible relocation destination for these climate change refugees in the form of the “Lilypad” concept – a completely self-sufficient floating city that would accommodate up to 50,000.  Read More

Deforestation driving CO2 buildup

Genghis Khan and his Mongol hordes had an impact on the global carbon cycle as big as today's annual demand for gasoline. The Black Death, on the other hand, came and went too quickly for it to cause much of a blip in the global carbon budget. Dwarfing both of these events, however, has been the historical trend towards increasing deforestation, which over centuries has released vast amounts of carbon dioxide into the atmosphere, as crop and pasture lands expanded to feed growing human populations. Even Genghis Kahn couldn't stop it for long.  Read More
