Fiji is suffering the biggest storm in the southern hemisphere

Fiji, a South Pacific country with about 881,000 inhabitants, yesterday declared the state of natural disaster due to the presence of Cyclone Winston, with sustained winds of 230 kilometers per hour and gusts of 325 kilometers per hour. The region is suffering the greatest storm recorded to date in the southern hemisphere.
The hole in the ozone layer is getting smaller
The hole in the ozone layer is getting smaller
The consumption of products that reduce the ozone layer has declined in just over 20 years to almost disappear. Therefore, as estimated, in 2050 the ozone layer will have recovered its initial level over most of the Earth. In this way, about 25 million cases of cancer will have been avoided.
Those on the right and those on the left, if they are young, do agree on the problem of climate change
Those on the right and those on the left, if they are young, do agree on the problem of climate change
Recent polls suggest that Generation Z and millennial American Republicans care about the weather much more than their older counterparts. They may even be as worried as the younger Democrats. That is, both ideological extremes would be united by this cause. Ideological bias It is no secret that Republicans and Democrats are not on the same wavelength when it comes to global warming caused by humans.
There is one thing that pollutes our oceans more than plastic: cigarette butts
There is one thing that pollutes our oceans more than plastic: cigarette butts
Cigarette butts are the main source of ocean debris, according to a new report by Ocean Conservancy, surpassing food wrappers, plastic bottles and caps and plastic bags. The toxins of the butts are consumed by the fish, which end up inside our bodies.
Forecasting the future knowing the past: sea level was 16 meters higher than the current 3 million years ago
Forecasting the future knowing the past: sea level was 16 meters higher than the current 3 million years ago
The Earth is warming and, as a result of the melting of ice sheets, such as those covering Greenland and Antarctica, the sea level will increase 3 millimeters each year, on average. However, more than 3 million years ago, when the Earth was between 2ºC and 3ºC warmer than in the pre-industrial era, the sea level was up to 16 meters higher than the current one.
What Carl Sagan thought about climate change in 1993
What Carl Sagan thought about climate change in 1993
The concern about the environment is not new. Perhaps its approach, and especially its popularization, is what has changed. Popularizing an idea has its positive facet, because it allows it to increase its concern about itself and better mobilize resources to solve it. However, there is a negative facet: every idea that becomes popular tends to be vulgarized so that it is understood by as many people as possible.
The human being has already begun to modify the environment 4,000 years ago, before what was believed
The human being has already begun to modify the environment 4,000 years ago, before what was believed
Itinerant agriculture and grazing had already affected more than 40 percent of the Earth's land area 4,000 years ago. This is what a new study from the School of Human Evolution and Social Change of the Arizona State University published in the journal Science suggests. The study also notes that continuous cultivation was common and widespread throughout most of the planet 2 years ago.
Fighting air pollution with these artificial trees
Fighting air pollution with these artificial trees
Worldwide, an estimated seven million people die from exposure to air pollution each year. Trees are excellent tools for cleaning the air of the atmosphere, but they have certain drawbacks: they need time and space to grow. That could change thanks to this artificial tree that absorbs as much air pollution as 368 real trees.
Microplastics are not only in the water and animals, but also begin to meet in the snow
Microplastics are not only in the water and animals, but also begin to meet in the snow
In recent years, microplastic particles have been detected repeatedly in seawater, drinking water and even in animals. But these tiny particles are also transported by the atmosphere and subsequently removed from the air, especially by snow, and even in regions as remote as the Arctic and the Alps, as a study recently published in the journal Science Advances suggests.
According to the IPCC, to combat climate change you have to eat less meat
According to the IPCC, to combat climate change you have to eat less meat
Air temperatures above the earth have risen 1.5 degrees Celsius since the pre-industrial era, twice as high as the global average that also includes the oceans. To combat this trend, the Intergovernmental Panel on Climate Change (IPCC), in a study presented this Thursday in Geneva, says that you have to eat less meat.
This July 2019 was the hottest in history since there are records
This July 2019 was the hottest in history since there are records
July of this year has been approximately 0.04 degrees warmer than July 2016, the previous warmest July in this data record, the Copernicus Climate Change newsletter. In general, July was 0.56 ° C warmer than the average for this month of 1981-2010, bearing in mind that July is typically the warmest month of the year in the world average.
Cleaning up microplastic pollution in seas and rivers could be easier with these carbon-based magnets
Cleaning up microplastic pollution in seas and rivers could be easier with these carbon-based magnets
A new system to clean the water sources of the microplastics that contaminate them without damaging the microorganisms that live in them has been developed by Australian researchers. Using small coil-based carbon-based magnets, researchers at the University of Adelaide (Australia) hope to clean seas and rivers more effectively.
Watching Netflix is ​​much more polluting than you think
Watching Netflix is ​​much more polluting than you think
1 percent of global C02 emissions are generated by watching videos online. Watching Netflix, then, has a significant effect on the planet. Also read (although reading books on paper, on average, seems less polluting than reading online or in ebooks). Online video streaming and viewing generates 300 million tons of carbon dioxide per year.
The cultivation of corn pollutes the air to such an extent that it is responsible for the deaths of thousands of people a year.
The cultivation of corn pollutes the air to such an extent that it is responsible for the deaths of thousands of people a year.
Forget about coal or diesel powered cars. They are both primarily responsible for the poor quality of our air. But we should also start looking at other foci that seem harmless to us, such as corn production. This is what a new study published in Nature suggests that analyzed US corn crops and has concluded that these could contribute to thousands of deaths from air pollution per year.
The most effective and economical solution to combat global warming: plant trees in the equivalent of the US area.
The most effective and economical solution to combat global warming: plant trees in the equivalent of the US area.
The six nations with more space for new trees are Russia, the United States, Canada, Australia, Brazil and China. All of them should host the massive planting of trees. Because that would be the most effective and cheap way to reverse global warming, according to a new study: planting no less than 1 billion trees in 9 million square kilometers.
This will raise the sea level due to the melting of Greenland (within 200 years)
This will raise the sea level due to the melting of Greenland (within 200 years)
Over the next 200 years, the melting of Greenland's ice at the current rate could contribute from 48 (almost half a meter) to 160 centimeters to sea level rise worldwide, according to a new study using models that used data from the NASA's IceBridge Operation airborne campaign.
There are more and more methane emissions, but the cause is unknown
There are more and more methane emissions, but the cause is unknown
There are many possible sources of methane, but it is not known exactly which is increasing both methane emissions on our planet. Most likely, it is a combination of all of them. In any case, discovering how it is produced and how we can reduce it is crucial, because, rising temperatures could in turn cause wetlands to release more methane, and changes in atmospheric chemistry could reduce the rate at which it decomposes methane, as a new study published in Science points out.

Plants may be extinguishing twice as fast as animals
According to a new study published in the journal Nature, Ecology & Evolution, and conducted by researchers at the Royal Kew Botanical Garden in England and the University of Stockholm, in the last 250 years, almost 600 plant species would have disappeared, more than double the number of mammals, birds and amphibians extinct in total.
Is it morally right to have children in a world condemned by climate change?
Is it morally right to have children in a world condemned by climate change?
Having children is environmentally unsustainable, as a sinister character in the Utopia series already explained. And, although we support the pyramid scam that constitutes the current pension system, those children we will have will be doomed to a certainly apocalyptic world. So, is it morally questionable to have children?
It is time to calculate the CO2 emissions caused by Artificial Intelligence: as many as five cars
It is time to calculate the CO2 emissions caused by Artificial Intelligence: as many as five cars
Training an Artificial Intelligence (AI) through deep learning has an environmental impact equivalent to five cars. Specifically, the lifetime of these five cars, including the environmental impact of manufacturing the cars themselves. This is what researchers at the University of Massachusetts, Amherst, have just calculated in a study, which found that the process of training an AI can emit more than 626,000 pounds of carbon dioxide.
