Boston Metal, an outfit spun out of the Massachusetts Institute of Technology, or MIT, uses electric currents to heat iron ore into a bright orange-white liquid, which converts into metal and cools as gray steel blocks.Testing and scaling technologies that remove the emissions from steelmaking isn’t the only challenge to decarbonizing the building material.
In fact, China’s push to continue cleaning up its air in the future could warm the entire northern hemisphere by 0.1 degrees Celsius by the end of the century, making it even tougher to keep the Earth’s temperature below the 1.5 Celsius degree (2.7 degrees Fahrenheit) warming limit that scientists say is necessary to avoid severe weather disruptions, increased rainfall, sea level rise, droughts, and other disastrous climate change effects by the year 2100.
“I really wanted to find this place that was rumored where there were a lot of rocks that result from explosive volcanic eruptions,” Elkins-Tanton says, “because that's the only way that we know of that you can effectively drive chemicals into the upper atmosphere where they'll get spun around the whole planet.” She was closing in on the geological signals of apocalyptic climate change.
Security and privacy-focused technologists have pointed to a long list of potential flaws in Apple and Google's system , including techniques that could reveal the identities of Covid-19 positive users or help advertisers track them, false positives from trolls, mistaken self-diagnoses, and faulty signals between phones.
These mayors are members of C40, a network of 94 large cities—Paris, Los Angeles, Shanghai, Lagos, to name a few—committed to meeting the goals of the Paris Agreement of limiting global warming to 1.5 degrees Celsius over preindustrial levels and reducing global greenhouse gas emissions by 50 percent by 2030.That declaration didn’t just reaffirm these cities’ efforts to fight climate change .
To meet its climate goal as stipulated in the Paris agreement, China will need to reduce its coal power capacity by 40 percent over the next decade, according to Global Energy Monitor’s analysis.
Lignite mining has already swallowed nearly half a million acres of Germany's land—including hundreds of villages, roads, and forests.Photograph: Tom HegenHegen's photos depict the Lusatia mining district in eastern Germany, from which roughly a third of the country's lignite hails.
Two years ago this month, a US-led military coalition declared victory against ISIS in Mosul, liberating one of Iraq's largest cities after three years of occupation by the radical Islamist group. Like the rest of Iraq, Mosul suffers from mines and unexploded bombs left behind from decades of war.
In a paper published Wednesday in the journal Joule, his team takes a closer look at the energy consumption of bitcoin mining, based on where miners are located and the types of machines they are using.

With a shrug of resignation, the officer explained that harvesting firewood in forest reserves and national parks was illegal and incidents like the one I had just witnessed were increasing tensions between the community and the Department of Forestry.
To boost and sustain its energy supply, India needs urgent investments and reforms to fix the inefficiencies that plague its entire electricity supply chain.

But the donations also put the firms in company with some of the event’s other sponsors, which included three groups known for their work attacking climate change science and trying to undermine efforts to reduce carbon emissions.
Coal isn’t just an energy source in Katowice — it’s a way of life.COP24’s president, Michał Kurtyka, a state secretary in Poland’s Ministry of Energy, argued in his opening remarks that bringing the climate summit to Katowice was a strategic decision: to exhibit a city and region in need of transition away from its lifeblood.
That’s going to require every nation to make changes, as well as individual cities, states and businesses.“It will require things that are more aggressive, like shutting down existing power plants and by 2030, we probably need to reduce global coal power production by 70 or 80 percent,” says Nathan Hultman, director of the Center for Global Sustainability at the University of Maryland.Hultman, who worked on climate issues in the Obama White House, says the solutions may be politically impossible for now.
While Facebook’s head of global policy Monika Bickert spoke, protesters from a group called Freedom From Facebook, seated just behind her, held signs depicting Sheryl Sandberg and Mark Zuckerberg’s heads atop an octopus whose tentacles reached around the planet.Freedom From Facebook has garnered renewed attention this week, after The New York Times revealed that Facebook employed an opposition firm called Definers to fight the group.
The world must invest $2.4 trillion in clean energy every year through 2035 and cut the use of coal-fired power to almost nothing by 2050 to avoid catastrophic damage from climate change, according to scientists convened by the United Nations.
Morrison and the new energy minister, Angus Taylor, are currently fixated on conjuring up a short-term fix they can offer voters before the election – a noticeable reduction in power prices – never mind the obvious point that having a medium term roadmap would help deliver your short-term objective.

Australia does not need to quit the Paris climate agreement because our commitments are non-binding, and new coal plants can continue to be constructed, according to the resources minister, Matt Canavan.
Our research on Australian coal transition – based on contributions by researchers at the Australian National University and the University of Melbourne – looks into the prospects for coal use in Australia and for exports, and the experiences with local transition in the case of the Hazelwood power station closure.
That rule would have restricted coal plants’ emission of a different pollutant: carbon dioxide, one of the chief causes of global warming.At the time the Obama administration put forth the mercury regulations, which took more than 20 years to formulate, E.P.A. officials estimated they would save thousands of lives and return economic and health benefits many times their estimated $9.6 billion annual cost.While owners of coal plants fought the rule in the courts, most have since complied with regulation.
In Tuesday’s Coalition parties meeting, where Turnbull won strong support for his energy policy, several reserved their right to cross the floor on the emissions reduction legislation, and later more said they might do so.
Richard Di Natale says Greens will work with Labor on climate but knows that major parties ‘won’t stand up to their corporate donors at the big end of town’. The Greens leader Richard Di Natale will promise to work with a new Labor government to get action on climate change back on track.
