The world, increasingly similar to “The day after tomorrow” | Digital Trends Spanish

Yet another concern. A study has revealed that the Atlantic Ocean Southern Overturning Circulation (AMOC), which creates the Gulf Stream, is approaching its tipping point as climate change causes it to weaken over time. It is a kind of maritime river warmer than the average temperature of the Atlantic and makes the climate of Western Europe mild and temperate. If shut down completely, scientists warn that much of North America and Europe could experience freezing temperatures for hundreds, even thousands of years. Basically this is what happens in the movie The day after tomorrow, from 2004, which shows this same problem, of course, in a more exaggerated way. 20th Century FoxIn the film, a climatologist played by Dennis Quaid warns international leaders about the sudden stop of this cu...

Climate Scientists Concerned About Space Tourism | Digital Trends Spanish

While the recent space trips of millionaires Richard Branson and Jeff Bezos have been highlighted, climate scientists are concerned about this situation. They are concerned about the growing increase in space tourism and about the stage that both entrepreneurs have just inaugurated, particularly about the effects that this trend could have on the health of the planet. Professionals fear that the increasing number of rocket flights and the increase in space tourism could damage Earth's atmosphere and contribute to climate change. According to Dallas Kasaboski, an analyst at space consultancy Northern Sky Research, a single Virgin Galactic suborbital flight lasting an hour and a half can generate as much pollution as a 10-hour transatlantic flight. This is concerning to researchers, espec...

This factor would be key to reducing the spread of COVID-19 | Digital Trends Spanish

We know that COVID-19 spreads through droplets of saliva that the infected patient expels when coughing or sneezing. Because of this, a group of scientists wanted to find out how these small particles behave under certain weather conditions. Thus, they proposed that the speed at which saliva droplets evaporate, determined by the temperature and relative humidity of the atmosphere, would be crucial for the rate of proliferation of COVID-19. The study was published in the journal Physics of Fluids. "We found that high temperatures and low relative humidity cause high evaporation rates from contaminated saliva droplets, significantly reducing the viability of the virus," says Talib Dbouk, one of the study authors in a release from the American Institute of Physics. In addi...

Drastic environmental change recorded in tree fossil in Peru | Digital Trends Spanish

Researchers at the Smithsonian Tropical Research Institute (STRI) were surprised by the finding of a huge fossil tree buried in an arid plateau in the Peruvian Andes, Europa Press reported. In a study published in the journal Science Advances, scientists point out that this and other high-altitude fossils are dramatic reminders that the environment has changed dramatically over the past 10 million years, but not in the way that past climate models suggest. By analyzing the tree, along with fossils of wood, leaves and pollen, they discovered that, when the plants were alive, "the ecosystem was more humid than predicted by old climate models," says Camila Martínez, a STRI fellow, who was part of Of the investigation. For his part, the head of the expedition, scientist Car...

The best apps and websites about hurricanes | Digital Trends Spanish

We know that in 2020 things have not been exactly calm, and the hurricane season in the Atlantic - which will last until November 30 - does not seem to want to give us a truce. This is a time period that defines most tropical cyclones that form in the North Atlantic, even though these can form at any time, as demonstrated by tropical storms Arthur and Bertha, on May 16 and 27, and this week, with the arrival of Laura to the coasts of Texas and Louisiana. They are phenomena that cannot be stopped, although you can prepare in the best way for when they touch land. Today, in fact, there are several hurricane trackers that will help you prepare for these potentially deadly events. Whether you are looking for predictive models of NOAA more advanced, or simply tips to find...
