Climate Change

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

Australian climate and ocean scientists are studying some of the planet's most remote areas using a multi-million dollar array of high-tech underwater equipment that provides data vital for the monitoring of almost one-third of the world's oceans. The kit of technology includes sensor floats and autonomous underwater vehicles, which combine with sensor tagged animals, moored scientific stations and satellite remote sensing to form the Integrated Marine Observing System (IMOS). All data collected is made available online, which represents a big step forward in climate science. Gizmag's Grant Banks takes a closer look at what makes IMOS tick.  Read More

Carbon capture and sequestration (CCS) is a hot area of research in the effort to fight global warming through the process of removing carbon from the atmosphere and ferreting it away within carbon soaking materials, a team from the University of Calcutta has found an unexpected (or should that be uneggspected) material that could trap carbon from the atmosphere in the form of eggshells. The team has demonstrated that the membrane that lines an eggshell can absorb almost seven times its own weight of carbon dioxide from the atmosphere, allowing the gas to be stored until environmentally friendly methods of disposing, or even using it, can be found.  Read More

Wind farms can cause change in local temperatures (Photo: Gizmag)

The benefits of wind farms in terms of global climate change are well recognized but according to researchers at the University of Illinois they can also affect local climates as well. The researchers observed that the area immediately surrounding a wind farm is slightly warmer at night and slightly cooler during the day compared to the rest of the region. The discovery could allow for strategies to mitigate those effects in areas where they are undesirable, or take advantage of them in others.  Read More
