Views: NASA Unveils ‘Earth System Observatory’ (ESO)

NASA Goddard (December 2022) – NASA is developing the Earth System Observatory, the core of which is five satellite missions providing critical data on climate change, severe weather and other natural hazards, wildfires, and global food production.

These observations will address the most pressing questions about our changing planet. Taken together as a single Observatory, NASA will have a holistic, 3D view of Earth to better understand how our planet’s complex systems work together and improve our capability to predict how our climate may change.

NASA’s Open Source Science strategy is the key to bringing the data from these missions together into a single observatory to help understand the earth as a system and accelerate our ability to use this understanding. These observations will better inform decision-makers on how our planet is changing, with greater precision on previously unimaginable scales – from entire continents down to individual trees, from atmosphere to bedrock.

Science: How Advanced Computer Models Project Future Climate Scenarios

Princeton University (December 13, 2022) – Earth’s atmosphere, oceans, and land surfaces interact and combine in powerful, yet often unseen, ways as part of a complex planetary system that determines the climate.

Over many decades, researchers at Princeton University have played a leading role in the development of advanced computational models that simulate interactions among these elements to inform an understanding of future climate scenarios under varying conditions.

In this video, climate scientists Gabe Vecchi and Laure Resplandy discuss how computational models are used to project future climate scenarios and inform mitigation strategies.

Storm Chasing: ‘Níłtsą́ – A Monsoon Film’ (2022)

Níłtsą́: the Navajo word for ‘rain’. Two years in the making. Almost 80 total days of chasing. Tens of thousands of miles driven. All packed into 12 minutes of the best storms and moments from the 2021/22 monsoon in Arizona. These films are my entire heart and passion for what I do.

Sometimes I’m so tired I don’t even want to chase, and I have to MAKE myself get into the truck and start driving. And it’s almost always worth it. One of my supporters on Patreon answered my call for a possible new name for the series. I wasn’t sure if I wanted to, and it would take something special to get me to do it. Leonard’s wife suggested Niltsa, and I immediately fell in love with it. It’s a gorgeous word.

Hurricanes: Why Storm Surge Can Be So Deadly

Storm surge is the deadliest part of a hurricane. Discover what causes this effect, and which regions are most at risk.

Storm surge is produced by water being pushed toward the shore by the force of the winds moving cyclonically around the storm. The impact on surge of the low pressure associated with intense storms is minimal in comparison to the water being forced toward the shore by the wind.
Wind and Pressure Components of Hurricane Storm Surge

The maximum potential storm surge for a particular location depends on a number of different factors. Storm surge is a very complex phenomenon because it is sensitive to the slightest changes in storm intensity, forward speed, size (radius of maximum winds-RMW), angle of approach to the coast, central pressure (minimal contribution in comparison to the wind), and the shape and characteristics of coastal features such as bays and estuaries.

Research: How Africa Keeps The Amazon Green

Jet streams sprinkle North African dust over the Amazon, providing the rain forest with much needed nutrients. Changing wind patterns and increasing smoke may shift the system.

Science: Race-Based Medicine, Space Tourism & Western U.S. Heatwave

Race-based medical practises are being challenged more and more, as it becomes increasingly clear they have little basis in science. 

The team finds out why adjustments for race and ethnicity are still being made in medicine, despite the potential harm and healthcare implications they cause. It’s been a massive week for the future of space tourism – the team shares a clip of a very excited Richard Branson who’s recent journey into microgravity has set the stage for the launch of Virgin Galactic’s first commercial space flights. The team gives an update on the dramatic heatwave ravaging the US, as more record high temperatures are set, continuing to leave destruction in its wake. They also explain what ‘impact gardening’ is and why it might help us find alien life on Jupiter’s moon Europa, and they share important news on the state of the cosmetics industry in Neolithic times. On the pod are Rowan Hooper, Chelsea Whyte, and Layal Liverpool.

Analysis: The Western U.S. Drought’s Major Impacts

Watering the Country’s Food Basket Is Becoming a Challenge

Droughts are part of a natural cycle of water. But the drought currently gripping the Western U.S. has climate scientists concerned that the cycle may be shifting. This has major implications for those who rely on the water the most: farmers and the communities they surround. Photo Illustration: Carter McCall/WSJ

Climate: How California’s Drought Fuels Disasters

Each year, California and the Southwest break new records for droughts and high temperatures, leading to heat waves, wildfires, and even flooding. Learn how these catastrophes operate together—and how engineers are working on new technologies to help us survive.
