The Dubious Promise of Bioenergy Plus Carbon Capture

Climate change agreements rest on negative emissions technologies that may be unachievable.

technologyreview – While many scientists and climate change activists hailed December’s Paris agreement as a historic step forward for international efforts to limit global warming, the landmark accord rests on a highly dubious assumption: to achieve the goal of limiting the rise in global average temperature to less than 2 °C (much less the more ambitious goal of 1.5 °C), we don’t just need to reduce emissions of carbon dioxide to essentially zero by the end of this century. We also must remove from the atmosphere huge amounts of carbon dioxide that have already been emitted (see “Paris Climate Agreement Rests on Shaky Technological Foundations”).

Doing so will involve “negative emissions technologies”—systems that capture carbon dioxide and store it, usually deep underground. Such technologies are theoretical at best, but they are considered critical for achieving the Paris goals. Of the 116 scenarios reviewed by the Intergovernmental Panel on Climate Change to achieve stabilization of carbon in the atmosphere at between 430 and 480 parts per million (the level considered necessary for a maximum 2 °C rise in temperature), 101 involve some form of negative emissions.

What’s really important about China’s stock market disaster, and what’s not

January 7

Washingtonpost – You can only defy financial gravity for so long. At some point, what went up for no reason must come down for a very good one, no matter what the government does to try to keep it aloft.

Which is to say that it was another disastrous day for Chinese stocks. On the plus side, though, it was a short one. Indeed, China’s market was only open for 14 minutes on Thursday before it fell the maximum 7 percent it’s allowed to in a single session. It’s the second time that’s happened this week, enough to erase almost all its gains since the summer. Tiếp tục đọc “What’s really important about China’s stock market disaster, and what’s not”

Về một chữ trong Truyện Kiều và cú đánh điểm huyệt

Mai An Nguyễn Anh Tuấn

Trong bài “Đôi điều về bản Truyện Kiều kỷ niệm 250 năm của Hội Kiều học” ( tác giả Minh Minh, trên tạp chí Hồn Việt số 96, 9-2015), qua một số dẫn chứng đưa ra nhằm mục đích hạ bệ cuốn sách mà tác giả chế giễu là “tốt mã này”, có một dẫn chứng mà theo tôi chính là “cú điểm huyệt” của Hồn Việt: “Hoặc như: Mày xanh trăng mới in hằn (câu 1793). Chữ hằn nghe thô tục quá. Hai câu thơ xinh đẹp như ngọc: Mày xanh trăng mới in ngần/ Phấn thừa hương cũ bội phần xót xa mà để cho một chữ hằn lọt vào thật không khác gì một vết sẹo trên khuôn mặt của nàng Kiều. Lưu ý rằng trong chữ Nôm, chữ 痕   có thể đọc ngần, hằn – nhưng ngần mới là chữ “tuyệt diệu!”. Tiếp tục đọc “Về một chữ trong Truyện Kiều và cú đánh điểm huyệt”

6 Shocking Reasons Why You Can Never Trust “Organic” from China
by | January 8, 2016


Polluted water is a growing problem in China, where it may be used to water crops.

Multiple recent reports exposed conventional foods manufactured in China as fake and even toxic: scams involving rice that contains plastic, fake eggs made from chemicals and many food items containing high levels of arsenic.Now that country-of-origin labeling has been removed by Congress (for meat), and companies are struggling to find new sources of food to meet the growing demand for organics in the United States, it’s becoming more likely that your organic food could come from China or other countries rather than U.S. farmers.
