Climate change: it’s not a solar panel, it’s a woman
Most people think about installing more solar panels and windmills when it comes to reducing carbon emission and global warming. However, there’s something else that will have an even bigger positive impact: elevating the role of women, particularly in the developing world. Education of girls and Read More...
At last, some Republicans are joining the climate change fight
Global warming has been accepted by almost every government and political party in the world—except for the Republican party in the U.S. So, it’s major news that a Republican member of the House of Representatives has introduced legislation to implement a carbon tax. Starting in 2020, the tax Read More...
Where politicians fail, kids are succeeding: the success of climate change suits
Nobody could have predicted children would get this far. From Colombia and Belgium to India, Norway and the U.S., they are succeeding bringing lawsuits arguing that their governments have violated “the youngest generation’s constitutional rights to life, liberty, and property” by adopting Read More...
Global warming and a healthy planet: It’s not your car, it’s your diet
The largest human source of carbon dioxide emissions is from the combustion of fossil fuels. At least, that is what we have been told. A new report forecasts that that is rapidly changing. The meat and dairy sector could be responsible for 80 percent of the greenhouse gases by 2050. It may not be Read More...
If you want to save on carbon emissions, travel by cargo ship
Many people are concerned about the carbon footprint of their air travel. A round-trip trans-Atlantic flight can easily gobble up a ton of carbon dioxide per passenger—about half the annual emissions an individual should aim for if we’re to limit global warming to 2 degrees Celsius. If you are Read More...
Norway invites bids for storing CO2 on its continental shelf
Norway on Thursday invited companies to submit bids to use subsea reservoirs to store carbon dioxide near the country’s largest oil and gas field, Troll. The Nordic country aims to develop a full-scale carbon capture and storage (CCS) by 2022 as part of its commitment to slow climate change Read More...
'Electrogeochemistry' captures carbon, produces fuel, offsets ocean acidification
Limiting global warming to 2 degrees Celsius will require not only reducing emissions of carbon dioxide, but also active removal of carbon dioxide from the atmosphere. This conclusion from the Intergovernmental Panel on Climate Change has prompted heightened interest in "negative emissions Read More...
Coal plant waste helps build environmentally-friendly, cementless concrete
Concrete production is one of the largest sources of carbon dioxide emissions in the world, after transportation and energy. To make the ubiquitous building material more environmentally friendly, the industry has been adding by-products from coal-fired power plants, but doing so had its own Read More...
Cost plunges for capturing carbon dioxide from the air
Pulling carbon dioxide (CO2) from the air and using it to make synthetic fuel seems like the ultimate solution to climate change: Instead of adding ever more CO2 to the air from fossil fuels, we can simply recycle the same CO2 molecules over and over. But such technology is expensive—about $600 Read More...
This power plant produces energy without emissions. Here’s why that’s a big deal
In 2016, we caught wind of a natural gas power plant being constructed in Texas that claimed it would produce energy without emissions. It promised to capture its own carbon dioxide emissions, not in a separate, expensive, power-intensive process like conventional carbon-capture facilities, but as Read More...
