#ClimateChange will make #rice toxic, say researchers
Eaten every day by billions of people and grown across the globe, rice is arguably the planet’s most important staple crop, with half the world’s population relying on it for the majority of its food needs, especially in developing countries.

Africa: The Role of Carbon Dioxide in Airborne Disease Transmission - a Hidden Key to Safer Indoor Spaces: [The Conversation Africa] We've long known that environmental factors - from humidity and temperature to trace chemical vapours - can influence how pathogens, such as viruses, bacteria and fungi, behave once released into the air.

Regional climate signals pose new challenges for climate science
#ClimateScience has correctly predicted many aspects of the #climate system and its response to increased atmospheric #CarbonDioxide concentrations. Recently, discrepancies between the real world and our expectations of regional climate changes have emerged, as have disruptive new computational approaches.
What the authors describe as the dominant paradigm or "standard approach" of climate science has been developed over the last 60 years by applying fundamental laws of #physics to the climate system under the assumption that small-scale processes are determined by statistical averages dependent on large scales (parameterization).
As with the evolution of other scientific fields, discrepancies have emerged in climate science with respect to how regional #ClimateChange is evolving. For example, the eastern Tropical #Pacific has cooled contrary to all model predictions. Neither was the increased frequency of blocking weather conditions over #Greenland in summer anticipated.
In particular, discrepancies are accumulating in the tropics where changes in the large-scale tropical circulation are known to grow out of instabilities that occur at small and intermediate scales. These scale-coupling mechanisms do not operate in the current generation of #ClimateModels.
"The challenge for conceptual work will be to identify which physics missing from the standard approach is most important for regional changes, and how to incorporate it," says Stevens.

"Carbon Dioxide Levels Highest in 800,000 Years"
NASA's Webb Images Young, Giant Exoplanets, Detects Carbon Dioxide
Findings suggest giant exoplanets in HR 8799 system likely formed like Jupiter and Saturn.
The first planet outside our solar system was discovered in the 1990’s, but it wasn’t until more than a decade later astronomers actually obtained a direct image of one. It’s extremely difficult to image an exoplanet, as stars in other planetary systems can be thousands of times brighter and bigger than their planets.
NASA’s James Webb Space Telescope is equipped with a highly sensitive coronagraph, a tiny mask that blocks the light of the star, allowing Webb to image exoplanets.
Webb’s new images of two iconic systems, HR 8799 and 51 Eridani, and their planets have stunned researchers, and provided additional information into the chemical make-up of the young gas giants.
