Global greenhouse gas emissions increased 2.3 percent in 2013, reaching a record high, showing that the world is still far from being able to control global warming. However, the average growth rate in the last decade has been 2.5 percent.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.
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 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.
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.
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?
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.
Temperate grasslands and thickets, that is, grasslands and steppes, form a biome whose predominant ecosystems are grasses, juncales, grasses or grass. Most of the meadows have been extensively altered and are now the main world regions of cereal production such as wheat, corn and other grains.
