On Jan. 14 at 1:23 EST (0623 UTC) NASA’s Aqua satellite analyzed Tropical Storm Claudia using the Atmospheric Infrared Sounder or AIRS instrument. AIRS found coldest cloud top temperatures as cold as or colder than (purple) minus 63 degrees Fahrenheit (minus 53 degrees Celsius) north and east of Imelda’s center.

The “bio-economy” uses plants, microorganisms or fungi to develop chemical products, medications and other inputs for consumer goods German ministers on Wednesday agreed an action plan for the “bio-economy” worth 3.6 billion euros to help sustainable resources replace material of fossil origin in everyday products. Research and agriculture ministers Anja Karlizcek and Julia Kloeckner will

Brazil invested nearly $100 million in rebuilding the Comandante Ferraz Antarctic Station on King George Island Brazil will open a new research base in Antarctica this week, officials said Tuesday, eight years after a fire destroyed its original scientific outpost. The government invested nearly $100 million in the reconstruction of the Comandante Ferraz Antarctic Station,

This image of the UV aerosol index from the Suomi NPP satellite OMPS Nadir Mapper instrument showing a “close-up” from Jan. 13, 2020 (specifically orbit 42546). The image reveals that the smoke has now made its all the way back to eastern Australia (black circle). The red circle shows “newly formed” (or current) smoke that

In school buildings with indoor air quality related problems, such as moisture damage, temperature problems or poor ventilation, pupils experience slightly more symptoms than in buildings in which conditions are stated to be good based on expert evaluation. However, the association between indoor air quality of the school building and the pupils’ symptoms was so

However, extreme heat does not affect all people equally. Surface temperatures in different neighborhoods within a single city can vary by a whopping 20 degrees

A new paper quantifying small levels of iodine in Earth’s stratosphere could help explain why some of the planet’s protective ozone layer isn’t healing as fast as expected. The paper posits a set of connections that link air pollution near Earth’s surface to ozone destruction much higher in the atmosphere. That higher-level ozone protects the

There are effectively only two seasons in the High Arctic: a long winter and a milder summer season. Arctic Ocean bottom water temperatures vary greatly from winter to summer season. This is also evident in the study area offshore Svalbard. Credit: B. Ferré/CAGE, UiT. The atmospheric concentration of methane, a potent greenhouse gas, has almost

In response to future fossil fuel burning, climate computer models simulate a pronounced warming in the tropical oceans. This warming can influence the El Niño phenomenon and shift weather and rainfall patterns across the globe. Despite being robustly simulated in computer models of the climate system, the origin of this accelerated tropical warming has remained
