One of the ways that scientists propose that we tackle the problem of global warming is to actively remove greenhouse gases, such as carbon dioxide, from the atmosphere. To be an effective compliment to reducing our CO2 output from transport and industry, carbon sequestration will have to be done on a massive scale, meaning that the materials used in the process will need to be plentiful. One of those materials, magnesite, readily absorbs CO2, but there are both practical and economic limits keeping industry from mining the mineral in quantities large enough to be effective. However, researchers in Canada have discovered a way to quickly produce the mineral artificially.read more

While the world might be making the steady shift away from fossil fuel energy sources, there is concern that avoiding a climatological catastrophe might take more than simply halting our production of carbon dioxide waste, and that our civilization might need to start actively removing excess CO2 from the atmosphere. Numerous companies around the planet have been developing such an idea, a process called "carbon sequestration", including a Canadian company that is looking to do more than just remove carbon dioxide from the atmosphere: they plan to recycle the recovered greenhouse gas and use it as a carbon-neutral fuel source.

Hawaii’s Mauna Loa Observatory has reported that worldwide carbon dioxide levels reached a new record high in April, hitting 410.31 parts per million (ppm). This is the highest concentration of this greenhouse gas seen over the course of human history–and prehistory, for that matter–as the Earth’s atmosphere hasn’t seen CO2 levels this high in well over 800,000 years, and possibly as long as 20 million years.

The United States Geological Survey has confirmed that a bright meteor that broke up over the Detroit area on the evening of January 16 caused a 2.0 magnitude earthquake in Michigan. The meteorite fell about five miles (8 kilometers) from the village of New Haven.

"After reviewing several observational datasets, the NWS can confirm the flash and boom was NOT thunder or lightning, but instead a likely meteor," tweeted the Detroit’s National Weather Service office, in response to social media activity regarding the 8:08 PM event. The USGS confirmation followed shortly after the NWS tweet.
