We’re going to Jezero!
Posted by Alberto Lao in categories: chemistry, climatology, space
At Jezero, Mars 2020’s goal will be “to explore the history of water and chemistry in an ancient crater lake basin and associated river-delta environments to probe early Martian climates and search for life.”
NASA announced this morning the selection of Jezero crater for the landing site of the Mars 2020 mission. Jezero is a 45-kilometer-wide crater that once held a lake, and now holds a spectacular ancient river delta.

A dark matter hurricane is headed our way
Posted by Michael Lance in categories: climatology, cosmology
According to a recent paper, the Earth is caught directly in the crosshairs of a cosmic hurricane. A swarm of nearly 100 stars, accompanied by an even greater amount of dark matter, is aimed directly at our stellar neighborhood and there’s nothing we can do to stop it; in fact, the vanguard is already upon us. This sounds like a perfect summer blockbuster movie, starring The Rock and Chris Pratt, or maybe Scarlett Johansson and Charlize Theron.

The Tragedy of the Commons, Revisited
Posted by Xavier Rosseel in categories: climatology, governance
Over two decades, I’ve worked with many collaborators studying infrastructure commons and knowledge commons. We developed the Governing Knowledge Commons framework, adapting Ostrom’s empirical approach to the special characteristics of knowledge resources. Understanding how communities share and develop knowledge is crucial in today’s “information society.” And, of course, sharing and developing knowledge is critical to successful governance of natural resources, especially on a global scale. Using the GKC framework, we’ve made substantial progress toward an empirical picture of knowledge-related commons governance. But it’s not nearly enough. Here’s why.
A classic study of the perils of resource sharing, with implications for how we deal with climate, has been updated.

Celebrating the amazing women of Antarctica
Posted by Genevieve Klien in category: climatology
Women have made a massive impact on scientific research in Antarctica, but they don’t get remotely the recognition they deserve. Science-celebrator Steph Green wants to do something about that.
Antarctica, the edge of the world – a seemingly endless expanse of glacial and sea ice, with no indigenous human population and an inhospitable climate. If there was any part of the world untouched by the patriarchy, surely this would be it?
Not so. Despite oral history from Oceania indicating female explorers visited the region, women have often been excluded from Antarctic exploration and scientific discovery. When Ernest Shackleton advertised for fellow adventurers in 1914, three women applied to join him, but they were not included. In 1937, 1300 women applied to join a British Antarctic Expedition. How many went to the frozen continent? Not a one.

For eco-conscious city dwellers, urban agriculture is one road to real impact
Posted by Genevieve Klien in categories: climatology, habitats, sustainability
Eco-consciousness is a hot trend. It’s become common occurrence to see shoppers with reusable grocery totes at the supermarket. Bamboo straws are flying off shelves as people opt for eco-friendly products. Urban gardening and composting, too, has taken root as consumers try to minimize their carbon footprints.
These small actions are encouraging first steps, but they’re not enough when it comes to tackling agricultural contributions to climate change. Strong-worded warnings from the UN’s Intergovernmental Panel on Climate Change (IPCC) detail the potential for climate disasters to worsen if modern consumption patterns don’t change — and soon.
There’s evidence that reimagining urban environments’ food systems might help reduce carbon emissions. With more than 60% of the global population expected to live in cities by 2030, urban agriculture might be one piece of the puzzle for reducing strain on city resources. The practice typically involves growing food in smaller, city environments such as on rooftops, apartment balconies, or even walls.

Destroying nuclear waste to create clean energy? It can be done
Posted by Genevieve Klien in categories: climatology, internet, nuclear energy, solar power, sustainability
If not for long-term radioactive waste, then nuclear power would be the ultimate “green” energy. The alternative to uranium is thorium, a radioactive ore whose natural decay is responsible for half of our geothermal energy, which we think of as “green energy.” More than 20 years of research at the European Centre for Nuclear Research (CERN), the birthplace of the internet and where Higgs boson was discovered, demonstrate that thorium could become a radically disruptive source of clean energy providing bountiful electricity any place and at any time.
Coal and gas remain by far the largest sources of electricity worldwide, threatening our climate equilibrium. Non-fossil alternatives, such as solar power, use up a forbidding amount of land, even in sunny California, plus the decommissioning will pose a serious recycling challenge within 20 years. Solar is best used on an individual household basis, rather than centralized plants. Wind requires an even larger surface area than solar.
As Michael Shellenberger, a Time magazine “Hero of the Environment”, recently wrote: “Had California and Germany invested $680 billion into nuclear power plants instead of renewables like solar and wind farms, the two would already be generating 100% or more of their electricity from clean energy sources.” Correct, but the disturbing issue of long-term nuclear waste produced by conventional, uranium based, nuclear plants still remains.

A ‘dark matter’ hurricane that we can’t see or hear is blasting past Earth, and it’s one of the universe’s biggest conundrums
Posted by Michael Lance in categories: climatology, cosmology
If astronomers’ calculations are correct, the Solar System is right in the middle of a turbulent space event.
The mysterious hurricane of “dark matter” leaves astronomers puzzled, but the remnants of dwarf galaxies could help prove this phenomenon’s existence.

How California Needs to Adapt to Survive Future Fires
Posted by Genevieve Klien in categories: climatology, sustainability
California is burning for very good reasons, like climate change and population growth. But it doesn’t have to be this way.

How algae could sustainably reduce the carbon dioxide concentration in the atmosphere
Posted by Genevieve Klien in categories: climatology, sustainability
In collaboration with fellow researchers, chemists at the Technical University of Munich (TUM) have developed a process that, according to initial calculations, can facilitate economically removing the greenhouse gas carbon dioxide from the atmosphere. The latest World Climate Report (IPCC Special Report on Global Warming of 1.5 ° C) acknowledges the global relevance of the process.
