What they don’t tell you about climate change
Stopping the flow of carbon dioxide into the atmosphere is not enough. It has to be sucked out, too.

Can Bringing Back Mammoths Help Stop Climate Change?
If you managed to time travel back to Ice-Age Europe, you might be forgiven for thinking you had instead crash-landed in some desolate part of the African savannah. But the chilly temperatures and the presence of six-ton shaggy beasts with extremely long tusks would confirm you really were in the Pleistocene epoch, otherwise known as the Ice Age. You’d be visiting the mammoth steppe, an environment that stretched from Spain across Eurasia and the Bering Strait to Canada.

How NASA Will Use Robots to Create Rocket Fuel From Martian Soil
The year is 2038. After 18 months living and working on the surface of Mars, a crew of six explorers boards a deep-space transport rocket and leaves for Earth. No humans are staying behind, but work goes on without them: Autonomous robots will keep running a mining and chemical-synthesis plant they’d started years before this first crewed mission ever set foot on the planet. The plant produces water, oxygen, and rocket fuel using local resources, and it will methodically build up all the necessary supplies for the next Mars mission, set to arrive in another two years.

Researchers Succeed In Turning CO2 Back Into Coal
Researchers from Australia have successfully turned carbon dioxide back into coal in a bid to prevent further catastrophe caused by global warming. The team led by RMIT University in Melbourne proposed that converting the greenhouse gas into a solid form addresses the environmental and economic concerns as well as fear of possible leaks from storage of recaptured CO2.

Radical proposal to artificially cool Earth's climate could be safe, new study claims
A new study contradicts fears that using solar geoengineering to fight climate change could dangerously alter rainfall and storm patterns in some parts of the world. Published in the peer-reviewed journal Nature Climate Change, the analysis finds that cooling the Earth enough to eliminate roughly half of warming, rather than all of it, generally would not make tropical cyclones more intense or worsen water availability, extreme temperatures or extreme rain. Only a small fraction of places, 0.4%, might see climate change impacts worsened, the study says.

To stop global catastrophe, we must believe in humans again
Because I am concerned about inequality and about the environment, I am usually classed as a progressive, a liberal. But it seems to me that what I care most about is preserving a world that bears some resemblance to the past: a world with some ice at the top and bottom and the odd coral reef in between; a world where people are connected to the past and future (and to one another) instead of turned into obsolete software.

Could Air-Conditioning Fix Climate Change?
It is one of the great dilemmas of climate change: We take such comfort from air conditioning that worldwide energy consumption for that purpose has already tripled since 1990. It is on track to grow even faster through mid-century—and assuming fossil-fuel–fired power plants provide the electricity, that could cause enough carbon dioxide emissions to warm the planet by another deadly half-degree Celsius.

Calgary researchers turn greenhouse gases into valuable carbon nanofibres
A researcher at the University of Calgary says she has developed a method of turning greenhouse gases into valuable carbon nanofibres. Mina Zarabian came up with the concept while completing her doctorate in chemical and petroleum engineering at the university's Schulich School of Engineering.

Artificial photosynthesis transforms carbon dioxide into liquefiable fuels
Chemists at the University of Illinois have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis. By converting carbon dioxide into more complex molecules like propane, green energy technology is now one step closer to using excess CO2 to store solar energy—in the form of chemical bonds—for use when the sun is not shining and in times of peak demand.

Adding 1 billion hectares of forest could help check global warming
Global temperatures could rise 1.5° C above industrial levels by as early as 2030 if current trends continue, but trees could help stem this climate crisis. A new analysis finds that adding nearly 1 billion additional hectares of forest could remove two-thirds of the roughly 300 gigatons of carbon humans have added to the atmosphere since the 1800s.

Scientists Are Genetically Engineering Plants to Fight Climate Change
Scientists have figured out how to genetically engineer plants to grow deeper roots, potentially improving carbon storage, drought resistance, and flood protection. This research comes as part of the Salk Institute’s Harnessing Plants Initiative, which seeks to use plants to capture carbon from the atmosphere and store it in the ground.

High-value opportunities exist to restore tropical rainforests around the world – here’s how we mapped them - questbuzz.com
The green belt of tropical rainforests that covers equatorial regions of the Americas, Africa, Indonesia and Southeast Asia is turning brown. Since 1990, Indonesia has lost 50% of its original forest, the Amazon 30% and Central Africa 14%. Fires, logging, hunting, road building and fragmentation have heavily damaged more than 30% of those that remain.

Mega-Trees Are the New Weapon Against Climate Change

Scientists say sustainable forestry organizations should lift ban on biotech trees
Look at anything made from trees—a ream of paper, a cardboard box, lumber—and it's probably stamped with the logo of the Forest Stewardship Council (FSC) or an equivalent organization. These nonprofits certify that forests are managed sustainably, and one common requirement is no genetically modified (GM) trees. But that ban hinders research and should change, researchers say in today's issue of Science. The technology, they argue, has important potential to remedy many pressing problems facing forests.

Philippines law would require students to plant 10 trees if they want to graduate
Philippines is one of the most deforested areas among other counties around the globe. The total forest area of the Philippines has decreased from 70 % to 20% in few years which has led to many problems such as floods and landslides. The Philippine law parliament is now concerned about its environment has decided to pass a law that states that students in order to graduate have to plant more than 10 trees while in college.

Greta Thunberg: ‘We are ignoring natural climate solutions’
The protection and restoration of living ecosystems such as forests, mangroves and seagrass meadows can repair the planet’s broken climate but are being overlooked, Greta Thunberg and George Monbiot have warned in a new short film. Natural climate solutions could remove huge amounts of carbon dioxide from the atmosphere as plants grow. But these methods receive only 2% of the funding spent on cutting emissions, say the climate activists.

Greta Thunberg is right: It’s time to haul ass on climate change
When Swedish climate activist Greta Thunberg addressed the elites assembled at the World Economic Forum in Davos, she concluded with a simple message: “I want you to act as if our house is on fire.” For those elites, it was unfamiliar language. They are accustomed to talking about climate change, but typically such talk amounts to ritual invocations of “urgency” coupled with promises about what might be achieved in 2030 or 2050.
