NASA helps you know how much the sea level will rise | Digital Trends Spanish

The worrying report prepared by the Intergovernmental Panel on Climate Change (IPCC) at the request of the UN forces us to imagine a dramatic scenario for the future of the planet. The impact of the climate phenomenon will be so strong that many island nations are at risk of disappearing before the end of this century. Because of this, NASA developed a useful online platform that allows you to see how much the sea level will rise anywhere in the world. This tool is in the NASA sea level portal. It allows users to choose a point on the planet and a period between 2020 and 2150 to discover how the increase in sea levels will affect that particular region. POT.At the site, NASA delivers a detailed location report based on projections from the IPCC assessment report, which is the most up-t...

Do birds select the plastic they consume in the ocean? | Digital Trends Spanish

Plastic in the oceans constitutes a serious threat to the different species of seabirds that inhabit these ecosystems. Everything indicates that this environmental problem will continue to get worse. A recent study commissioned by The Pew Charitable Trusts notes that the amount of this material in the ocean could triple by 2040 if the proper measures are not taken. The same reports assures that the plastic can remain in the ocean for hundreds of years and it is likely that it will never biodegrade. Currently, several studies are trying to determine how plastic impacts different species. Seabirds, for example, have been known to consume it, get trapped in it, and also use it to build their nests. Is there a selection? A study of Millennium Nucleus of Ecology and Sustainable Managem...

What is pandemic trash? A silent threat | Digital Trends Spanish

During the first weeks of the quarantine, many of us welcomed the unprecedented appearance of animals in urbanized places, the decreases in air pollution levels and the decrease in noise in cities. It seemed as if the planet was finally "taking a breather" with the large number of people confined to their homes. The truth is that this naive optimism seems to have been left behind and now a new ecological concern is emerging as a result of the health crisis caused by the coronavirus. This is the large amount of waste generated during the pandemic and which, to a large extent, ends up polluting the oceans, affecting the increasingly vulnerable marine fauna. A plastic pandemic Different international organizations already speak of a true "plastic pandemic" in relation to t...

The world map in case the water rises or falls 1,000 meters | Digital Trends Spanish

Recent studies suggest that sea levels will be more variable as the oceans warm due to increased greenhouse gas emissions. In this sense, what would happen if the water level rises or falls 1,000 meters? From the Spanish site of Sputnik, it is said that, in reality, it is difficult for the ocean to rise or fall 1,000 meters, since "such a volume of water simply cannot arise by itself or disappear from nowhere." Either way, share a couple of graphs from user BasedMap (Reddit), which show what the world map would look like in either case. What does Earth look like with 1000 meters of sea-level rise or drop?https://t.co/AxvIWTZ1vU#maps #ocean #sealevel pic.twitter.com/wbrCO4e0fj - Vivid Maps (@VividMaps) August 20, 2020 For the scenario of a 1,000 meter descent from the...

The asteroid Ceres has buried oceans and volcanoes | Digital Trends Spanish

The asteroid Ceres is a large rock mass that is orbiting somewhere between the planets Mars and Jupiter. And what seemed like a pure piece of space stone, was now vindicated before science. It turns out that NASA's robot spacecraft, Dawn, found evidence of oceans and volcanoes, in seven installments that were published this Monday August 10 in the journals Nature Astronomy, Nature Geoscience, and Nature Communications. Research suggests the possibility of an ocean of salty groundwater. In addition, this would have caused the great Occator crater of Ceres, which seeps from fractures in the rocky crust. "Ongoing activity at Occator brings additional independent evidence of a deep brine layer, and updates Ceres to the realm of ocean worlds," wrote mission scientist Daw...
