The Logic Behind Shanghai’s Massive New Urban Plan

January 12, 2022 CEN_com 0

In January 2021, Shanghai mayor Gong Zheng announced that Shanghai’s days as a unified city were numbered. Instead of one sprawling city covering the entire municipality, Shanghai is planning to build five new cities within its boundaries, as the suburban districts of Jiading, Songjiang, Qingpu, Fengxian, and Nanhui are turned into what Gong termed “comprehensive node cities with radiating and driving functions.” Gong’s speech marked the first time this plan had ever […]

Nepal’s Largest Hydropower Station Starts Operation

With the completion and operation of the Upper Tamakoshi hydroelectric power station, Nepal has not only resolved a long-standing problem of intermittent power shortages, but also realized the transformation from an electricity importer to an exporter. Nepal has begun to sell hydropower to India, which was once Nepal’s largest provider of aid. This has inspired people of the infrastructure construction in South Asia.The first generator unit at the Upper Tamakoshi […]

January 12, 2022 CEN_com 0

Data collected for a study conducted by researchers from 14 institutes in China, the United States and Italy, published 11 January 2022 in the journal Advances in Atmospheric Sciences, has found that 2021 was the hottest for the world’s oceans in recorded human history. They researchers found that the upper 2,000 meters in all oceans last year absorbed a greater amount of heat than the previous record set just the […]

Chinese mathematicians model effects of toxicants on ecology of polluted rivers

January 12, 2022 CEN_com 0

Two Chinese applied mathematicians have developed a spatio-temporal model to help determine criteria for water quality necessary to maintain a healthy aquatic ecology. The model could offer the basis for effective decision-making tools for water and environment managers, and help develop future policy guidelines surrounding specific target species and toxicants. When designing environmental policies to limit the damage of river pollution, it is paramount to assess the specific risks that particular pollutants […]

Clean household heating in northern China has environmental benefits: study

January 11, 2022 CEN_com 0

Many of China’s households still rely on small coal stoves for heat, which causes air pollution that damages health. To address these problems, the Chinese government launched a five-year “Clean Heating Plan” in 2017 with the goal of transitioning 70% of northern households away from coal and toward cleaner heating options. The plan is now in its final year. A study by a group of researchers from several Chinese Universities […]

How will China control its methane emissions?

January 11, 2022 CEN_com 0

“Climate change experts are optimistic that China will begin systematically reducing emissions of methane, a potent greenhouse gas of which the country is among the world’s biggest emitters, but they say more specific measures are needed still.” Introduction: Actions in China’s 14th Five-Year Plan Long neglected, methane reduction received its first-ever mention in China’s latest five-year plan. On March 13, China published its 14th Five-Year Plan, a policy blueprint for the years 2021 […]

Eighty seven percent of overseas coal power financed by G7 and other advanced economies

January 10, 2022 CEN_com 0

A recent Boston University study published in July 2021 found that Japanese, Korean and Western financiers bankroll 87 % of overseas coal power plants globally, contrary to the misconception that most new funding comes from public financing entities in China. In fact, before China banned any new funding of overseas coal projects, China accounted for only 13 % of financing for overseas coal power projects. The private sector from the G7 and other […]

Belt and Road spreads in US ‘backyard’ – Latin America and the Caribbean

January 10, 2022 CEN_com 0

Introduction The US has long considered Latin America as “America’s Backyard” – its exclusive neo-colonial zone following decline of European colonial powers. Since 1823, the “Monroe Doctrine” and US actions over the past 2 centuries to subjugate Latin America and the Caribbean, have made it clear that the US was, and still is determined to ruthlessly establish and maintain itself as the absolute hegemon in the region. However, rapid changes […]

Chinese solar researchers increase efficiency of solar cells

January 9, 2022 CEN_com 0

Chinese scientists have developed a hybrid cooling technique to reduce photovoltaic (PV) module temperatures by up to 12.86 C and increase power yields by 7.25%. “Researchers from Zhejiang University and Shanghai Jiao Tong University in China have developed a hybrid solar module cooling technique based on radiative cooling (RC) and the use of heat pipes to transfer heat”, PV Magazine reports. The scientists discussed their findings in “Enhanced radiative cooling of solar cells by integration with heat pipe,” […]

High-speed rail cuts greenhouse gas emissions

January 9, 2022 CEN_com 0

China’s high-speed railway network has led to a significant reduction in greenhouse gas emissions, a recent study has shown. The research found that the high-speed railway connection has led to an annual reduction of nearly 11.2 million metric tons of carbon dioxide equivalent greenhouse gas emissions by replacing road traffic, equal to 1.33 percent of greenhouse gas emissions in China’s transport sector. Published in the journal Nature Climate Change in […]
