Now a tropical storm, Hurricane Dora has been skirting southwestern Mexico's coast since it formed and has transported tropical moisture onshore that has produced some heavy rain showers. The Global Precipitation Measurement mission or GPM core satellite has analyzed those rainfall rates.
A team of researchers from the University of Cambridge have developed a new way of measuring the pressure inside volcanoes, and found that it can be a reliable indicator of future eruptions.
The US banned PCBs nearly four decades ago, but they persist in the environment and have been found in animals and humans since then. Now researchers report in ACS' journal Environmental Science & Technology that concentrations of airborne PCBs inside schools could result in some students inhaling the compounds at higher levels than they would consume through their diets. Exposure through both are lower than set limits, but cumulative amounts, researchers caution, could be concerning.
NASA-NOAA's Suomi NPP satellite captured an image of Dora at peak strength late on June 26 before it started moving over cooler waters that began sapping its power.
A warming climate is not just melting the Arctic's sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country's waters, says a new study.
The airborne dust carried in sand storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms.
Recent increases in an unregulated ozone-depleting substance, could delay recovery of Antarctic ozone levels by 5-30 years, depending on emissions scenarios. The findings, published in Nature Communications, suggest that a previously ignored chemical called dichloromethane may now be contributing to ozone depletion.
The fourth tropical cyclone of the Eastern Pacific Ocean season formed on June 25 and by June 26 it was already a hurricane. NASA-NOAA's Suomi NPP satellite passed over Dora on June 25 when it was a tropical storm and the next day it became the first hurricane of the season.
Using an off-the-shelf camera flash, researchers turned an ordinary sheet of graphene oxide into a material that bends when exposed to moisture. They then used this material to make a spider-like crawler and claw robot that move in response to changing humidity without the need for any external power.
Tropical storm Cindy was downgraded to a tropical depression after moving onshore near the Texas and Louisiana Border on Thursday June 22, 2017 and bringing a lot of rain with it. That rainfall was measured by NASA using satellite data.
