  There’s no escaping climate change as extreme weather events abound Ishaan Tharoor   Columnist July 14, 2023 at 12:00 a.m. EDT A man walks down a flooded street in Montpelier, Vt., on Tuesday. (Brian Snyder/Reuters) One can grow numb to the temperature records that keep ascending around the world . For months across the Northern Hemisphere, we have  seen heat wave after heat wave  spike thermometers, melt roads and devastate crops. This week alone, we may  see all-time temperature highs  across the world, including parts of the southwest United States and southern Europe. At the same time, other parts of the planet, such as north India and New England, are experiencing record rainfall. Readers of Today’s WorldView  are likely accustomed to the periodic missive about these snowballing, extreme weather events, and their inescapable link to a planet that is warming from man-made emissions. But the recent grim climate superlatives bear consider...

  Bathymetric surveys: improvements and barriers Developments and points for improvement Since the 1970s, remote sensing has increasingly been used to conduct underwater surveys. Several methodologies are employed in hydrographic surveying, from direct techniques such as probing rods to more sophisticated techniques such as satellite-derived bathymetry and altimetric radar. The growing need for data that is increasingly accurate and available with a quick turnaround has recently led to a worldwide effort to develop sensors and alternative techniques for measuring depth. Bathymetric survey platforms include surface vessels, submersible platforms, aircraft and satellites (see Figure 1). Vessels range from large ships, used in offshore surveys, to uncrewed vessels, either remotely controlled or autonomous. The most commonly used submersible platforms are autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs), both of which are used for high-resolution mapping in d...

Information hour on running a Satellite Event on Digital Twins of the Ocean The snapshot of the Summit could be found as follows. Detailed agenda will be updated when it is ready prior to the commencement of the Summit. Stay tuned! We sincerely call for abstracts submitting to the following sessions for in-depth discussions on advancing and applying DTOs 1. Ocean Observations & Data Systems Co-chairs:  Toste Tanhua, Marjolaine Krug, Yan Du Ocean observation is important to generate the information needed to understand, manage and protect the ocean. Data systems are essential for integrating ocean observations and key information for ocean and climate research. Ocean observations and data systems allow us to understand and improve our predictions of ocean systems, different ocean hazards, climate variability and global change, as well as to provide critical information for policymakers on ocean sustainable development. This session welcomes topics: (1) bringing together research...

  FIGHTING CLIMATE CHANGE ISN’T AN AUTOMATIC WIN FOR ENVIRONMENTAL JUSTICE Some simulated pathways for reducing emissions in the U.S. maintained or exacerbated existing racial inequities Air pollution over Los Angeles neighborhoods. Photo: rushay booysen/iStockPhoto In the United States in 2017, people of color were exposed to 10% more particulate matter air pollution compared to white people. This well-documented inequity has been baked into the fabric of American life by  racist housing policies  like  redlining  and has left a legacy of  negative health outcomes  for communities of color across the nation. The kind of sweeping cuts to greenhouse gas emissions needed to fight climate change are expected to improve air quality because burning fossil fuels also produces air pollution. But a new study from researchers at the University of California San Diego’s Scripps Institution of Oceanography and School of Global Policy and Strategy shows that while...
