Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA.
Continuing the planet’s long-term warming trend, the year’s globally averaged temperature was 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. 2020 edged out 2016 by a very small amount, within the margin of error of the analysis, making the years effectively tied for the warmest year on record.

As Facebook Inc. and Twitter Inc. banished users and groups supporting the violent mobs at the U.S. Capitol last week — including President Donald Trump himself — downloads surged for a less restrictive social media app called Parler. But in an effort to prevent further riot organizing, Google Inc. and Apple Inc. booted Parler from their app stores, and Amazon.com Inc. shut off its web services.
“We will not cave to pressure from anti-competitive actors!” John Matze, Parler Inc.’s chief executive officer, said on his site Friday. “We WON’T cave to politically motivated companies and those authoritarians who hate free speech!”
In reality, Matze doesn’t have much choice. His free-speech-centric network, where some extremists turned to rally insurgents and organize future uprisings, was deemed an “ongoing and urgent public safety threat” by Google. Apple quickly rejected as insufficient a Parler plan to moderate its content. Amazon employees asked that the web giant “deny Parler services until it removes posts inciting violence, including at the Presidential inauguration.” Amazon plans to shut down the service at midnight Sunday, according to Matze.

Academics are increasingly expected to share their research widely beyond academia. However, our recent study of academics in Australia and Japan suggests Australian universities are still very much focused on supporting the production of scholarly outputs. They offer relatively limited support for researchers’ efforts to engage with the many non-academics who can benefit from our research.
One reason engagement is expected is that government, industry and philanthropic sources fund research. And when academics share their research with the public, industry and policymakers, this engagement is good for the university’s reputation. It can also lead to other benefits such as research funding.

- Between the pandemic, rising food insecurity and poverty, and catastrophic disasters like wildfires, storms and droughts, 2020 was a year of challenges that prompted widespread calls for systemic change in how we interact with one another, with other species, and with the environment. Bringing about such changes will require transforming how we produce food and energy, how we move from one place to another, and how we define economic growth.
- But it’s a lot easier to talk about transforming systems than to actually do it. Because real change is hard, we’re more likely to slip back into old habits and return to business as usual than embrace paradigm shifts.
- Recognizing this limitation, World Resources Institute (WRI), a Washington, D.C.-based organization that operates in 60 countries, works across sectors by creating tools that increase transparency, create a common understanding, and provide data and analysis that enable action.
- WRI’s development of these platforms and tools has grown by leaps and bounds since the early 2010s when Andrew Steer joined the organization as president and CEO from the World Bank. Steer spoke with Mongabay during a December 2020 interview.

The latest version of NREL’s popular System Advisor Model (SAM) is now available, providing more robust data and seamless integration with other NREL models to help the renewable energy industry make informed project decisions.
SAM is free, publicly available modeling software for technical performance simulation and financial analysis of renewable energy projects and includes a desktop application, software development kit, and open-source code.
Updates to the model include:
- The addition of the latest solar resource data from NREL’s National Solar Radiation Database, including yearly and sub-hourly data and covering Europe, Africa, and Asia for the first time
- Improved battery dispatch for both front-of-meter and behind-the-meter battery storage applications
- Improved electricity bill calculations for distributed behind-the-meter financial models
- Implementation of NREL’s Solar Position Algorithm for sun angle calculations of solar performance models
- Integration of NREL’s Land-Based Balance-of-System Systems Engineering Model for improved wind power plant system cost estimation and design.
“With the recent improvements, we’re excited to continue to ensure that complex energy analysis questions can be answered quickly and easily,” said Janine Freeman, NREL lead for the SAM model.
The list below compiles and provides access to external databases. While the respective scopes of each of the databases are varied, all convey information relevant to wind and marine renewable energy and the environment. The list of databases is not exhaustive and will be updated as needed. If you have comments on incorrect or missing material, please email email@example.com.
Aiming to complement NREL’s Best Research-Cell Efficiency Chart and the Solar cells efficiency tables by Martin Green et al., which list the absolute best performing certified efficiencies for each major photovoltaic (PV) technology, emerging PV reports provides an alternative reference. We summarize the best results in the PV research, as published in academic journals (certified and uncertified) and with respect to the Shockley-Queisser efficiency limit, encouraging the reproducibility of the results. Unlike the established overviews, our new approach also deals with the best flexible, transparent/semitransparent and long-term photostable PV devices. In all cases, we also suggest protocols for best practices in characterization and reporting of emerging PV device performance.

- New proposed Feed-in-Tariff (FIT) extension by Vietnamese government would reduce tariffs for onshore and intertidal wind power by 17.4 per cent and 13.6 per cent respectively, one of the most dramatic reductions seen for wind power globally.
- According to the Global Wind Energy Council (GWEC), this FIT reduction threatens to deter investment and derail the long-term growth of wind power in Vietnam.
- GWEC welcomes a FIT extension to compensate for permitting and COVID-19-related delays, which collectively will cause Vietnam to miss its 800 MW of wind power capacity target by 41 per cent.
- GWEC, representing the global wind industry, recommends a minimum 6-month extension to the current FIT, followed by milder reductions to the FIT from May 2022 onwards.
3 December 2020, Singapore – The Global Wind Energy Council (GWEC) welcomes the recent decision by the Vietnamese government to approve an extension of the Feed-in Tariff (FIT) scheme for wind power in the country. However, the proposed dramatic reduction to the FIT risks seriously damaging the growth of Vietnam’s promising wind power sector, slowing down investment and the creation of new jobs and making it harder for Vietnam to meet growing energy demand.

The geopolitics of the Mekong river continue to evolve, with key announcements from China, Thailand and the Mekong River Commission.
Recent weeks have seen new developments in the ongoing tension over the Mekong river and its waters, as the river basin faces ecological crises and its waters play an ever-larger role in geopolitics.
Thailand has announced that it is reconsidering its decision to purchase power from the planned Sanakham Dam, a large hydropower project on the mainstream of the Mekong in Laos. Tiếp tục đọc “Geopolitics plays out on the Mekong with doubts on dams and promises of cooperation”
