Highlighted paper: Heat stored in the Earth system: where does the energy go? A deep roster of familiar names in climate research headed by Karina von Schuckmann have just published an updated and for the first time comprehensive accounting of energy being stored in the Earth system due to radiative imbalance caused by greenhouse gases added to the atmosphere by “us truly.” This is summarized as a single number called “Earth Energy Imbalance” (EEI), at slightly less than 0.5 Watts per square meter of Earth’s surface. When penciled out it’s an extremely large amount of energy

Why We're Committed to Ensuring Access to Parks for All by 2050

If there’s one thing we know for sure — especially amid the challenges of today’s pandemic — it’s that people need parks. From Detroit’s 1,000-acre Belle Isle Conservancy to the tiny “parklets” of Oakland, CA, parks and nature have revealed themselves as critical to our ability to find respite, connect with others, and engage in civic discourse during this time of great stress and isolation. In response to the surging demand

Building Back Better Demands More Thoughtful Tourism

While every major industry in the world has been affected by the COVID-19 pandemic, tourism — which represents 10 percent of world GDP — has been one of the hardest-hit economic sectors.   Even as national borders slowly reopen, the uncertainty associated with travel continues. According to the World Tourism Organisation (UNWTO) report on Related Travel Restrictions released in May, international tourism arrivals are expected to decline 58-78 percent compared to 2019.  As businesses focus on how to not only survive but recover from the impact of the pandemic, many are

Saharan dust cloud was most intense in decades, and more, though milder, are coming

This is a re-post from Yale Climate Connections by Jeff Masters The massive dust storm that formed over the Sahara Desert in mid-June invaded the southeastern U.S. June 25-28, bringing dangerous levels of air pollution, low visibility, and colorful sunsets. The air pollution event over parts of Texas and the Gulf Coast, composed of fine particulate pollution (PM2.5, particles less than 2.5 microns or 0.0001 inch in diameter) and PM10 (particles less than 10 microns in diameter) was one of the most widespread and intense observed in recent decades. According to FEMA meteorologist Michael Lowry, the intensity of the dust outbreak over the tropical Atlantic was by far the most extreme since the most detailed, continuous record of

EGU2020 – Sharing Geoscience Online – Citizens Science Session

Due to the Corona pandemic and subsequent efforts to slow its spread, this year’s General Assembly of the European Geosciences Union (EGU) with around 16,000 participants obviously couldn’t take place in Vienna, Austria. As already explained in the initial blog post published a few weeks ago, the organizers decided to still have the conference but to move it almost comletely online – not a simple task to do within just a few weeks and with around 700 sessions and 18,000 submitted abstracts in the program!

Legal Education for Scientists Events at the AGU Fall Meeting

This is a repost of the December 3rd entry in the Climate Science Legal Defense Fund blog, by CSLDF Executive Director Lauren Kurtz. The Climate Science Legal Defense Fund (CSLDF) and American Geophysical Union (AGU) want to help scientists understand their legal rights and responsibilities—we believe this knowledge is an essential part of every researcher’s professional development. So we’ve partnered on the “Legal Education for Scientists Program” for eight years, and are offering a range of events at the 2019 AGU Fall Meeting in December. Among this year’s events are two workshops featuring experts from CSLDF, the American Civil Liberties Union (ACLU), and Union of Concerned Scientists (UCS). Whether

36 articles with 8 as open access Natural variability With search variables held constant, our collection of articles this week is relatively small compared to others. It’s likely not a secular trend. Could it be the time of year? Given how journal editors must hound reviewers for comments on papers, the chronological smearing effect of procrastination means seasonality is an unlikely candidate for paltry search results.
