NASA analyzed the cloud top temperatures in the newly formed Tropical Cyclone Irondro using infrared light to determine where the strongest storms were located.
Dropping Mentos® candies into a bottle of soda causes a foamy jet to erupt. Although science fair exhibitors can tell you that this geyser results from rapid degassing of the beverage induced by the candies, the precise means by which bubbles form hasn't been well characterized. Now, researchers reporting in ACS' Journal of Chemical Education used experiments in the lab and at various altitudes to probe the mechanism of bubble nucleation.
A new Caltech-JPL study determines the impact of the severe 2019 floods, and offers scientists a new tool for measuring regional-scale carbon dioxide absorption by plants.
A study from the University of Surrey has provided a comprehensive guide on which tree species are best for combating air pollution that originates from our roads -- along with suggestions for how to plant these green barriers to get the best results.
The Montreal Protocol of 1987 phased out production of ozone-destroying substances such as chlorofluorocarbons (CFCs). Beginning around 2000, concentrations of those chemicals in the stratosphere started to decline and the ozone hole began to recover. In this study, researchers have shown that around the year 2000, the circulation of the Southern Hemisphere also stopped expanding polewards -- a pause or slight reversal of the earlier trends.
Municipal solid waste is trash -- such as plastic, food scraps and lawn clippings -- that goes into garbage bins and doesn't get recycled. Most of this waste is buried in landfills or is incinerated. Now, researchers reporting in ACS' Environmental Science & Technology have shown that when disposed of in this way, municipal solid waste can be an important source of antibiotic-resistance genes in the air.
Years of cloud data over a shipping route between Europe and South Africa shows that pollution from ships has significantly increased the reflectivity of the clouds. More generally, the results suggest that industrial pollution's effect on clouds has masked about a third of the warming due to fossil fuel burning since the late 1800s.
Former Tropical Cyclone Herold is now a fading area of low-pressure in the Southern Indian Ocean and NASA's Aqua satellite provided forecasters with a visible image.
Wind shear pushed former Tropical Cyclone Herold apart and infrared imagery from NASA's Aqua satellite showed the system with very little strength remaining.
Injecting the right dose of sulphur dioxide into Earth's upper atmosphere to thicken the layer of light reflecting aerosol particles artificially could reduce the effects of climate change overall, exacerbating change in only a small fraction of places, according to new research by UCL and Harvard.
