What was the Sahara like before it became the biggest hot desert on the planet? A Terra é planeta antigo, para o conceito humano de tempo.
Com cerca de 4,5 bilhões de anos, ela foi palco de profundas mudanças em sua superfície. Se uma pessoa viajasse para um momento bem distante no passado, encontraria um cenário bastante diferente do atual. Entre essas transformações, está a formação do Saara, o maior deserto quente do planeta — com mais de 9 milhões de quilômetros quadrados —, que, há 11 mil anos, abrigou lagos, rios, pastagens e até mesmo florestas. O que transformou esse lugar verde e úmido em uma das regiões mais secas do mundo? É importante destacar que mensurar com exatidão o que provocou esta profunda mudança é um desafio de quebra-cabeça, pois tudo no planeta está intimamente ligado. Mudança no eixo da Terra Os principais estudos sobre a formação do Saara apontam a alteração do eixo da Terra como um dos principais fatores de seu surgimento.

United Nations Climate Change Report Is a "Code Red for Humanity" The report proves that the climate crisis is even more widespread and dire than previously thought.
It makes it clear that unless major action is taken, we will not meet the Paris Agreement’s 1.5-degree goal — and we will therefore achieve irreversible climate catastrophe within the decade. The United Nations climate change report is “a code red for humanity.” On Monday, Aug. 9 the United Nations’ Intergovernmental Panel on Climate Change (IPCC) published The Working Group I report, which is the IPCC’s Sixth Assessment Report’s sixth installment (and clocks in at 3,949 pages). The report will be published in full sometime next year, according to a press release by the IPCC.
Dubai Is Creating Artificial Rainstorms as a Form of Heat Wave Relief. Cities worldwide have endured insufferable heat waves this summer — Portland, Ore., Seattle, Wash., and Vancouver, B.C., Canada, are only a few of the effected areas.
Parts of the Middle East, such as Dubai, have also been enveloped by a massive heat wave, with temperatures hitting the triple digits for days at a time. But researchers from England's University of Reading have done quite a bit of work, and figured out how to create artificial rainstorms to cool things down. "Our ability to manipulate weather is puny compared to the forces of nature," stated University of Reading's Professor Robert Van de Noort. "We are mindful that we as a University have a big role to play, by working with global partners to understand and help prevent the worst effects of climate change.”
Humans exploiting and destroying nature on unprecedented scale – report. Posted on: September 11, 2020 at 6:45 pm Advertisement Over the last several years, we have witnessed a number of disastrous environmental events, and from what it looks like, it has a lot to do with humans destroying nature.
The devastating fires in Australia, California, and Brazil have wiped out millions of acres of forest. Extreme weather like hurricanes, earthquakes, and tornadoes have destroyed people’s homes and taken countless lives. Mother Elephant And Her Calf Attacked With Firebombs As Deforestation Drives Them Into The Paths Of Humans. Due to the deforestation across India, numerous elephants can be seen wandering in the villages and communities.
Amazon rainforest ‘being destroyed at a record rate in coronavirus lockdown as illegal loggers exploit crisis’ ILLEGAL loggers in the Amazon rainforest are taking advantage of the coronavirus pandemic as the rate of deforestation has doubled, researchers have warned.
Trees are being cut down at twice the rate of last year with almost 2,000 square miles of the Amazon being cleared in the first three months of 2020. ⚠️ Read our coronavirus live blog for the latest news & updates. 3.4.20 a tribute to protectors at Crackley Woods. Bomullsodlingar fick en av världens största sjöar att försvinna. 3,000 Dolphins Found Dead on the Coast of Peru. Along just one stretch of coastline in Peru, more than 3,000 dead dolphins have washed ashore in just the last 3 months, and the disturbing trend may only be escalating.
With the latest discovery of 481 lifeless dolphins there in recent days, residents have begun to demand an explanation for the mysterious mass deaths -- and as far as enlisted experts can tell, offshore oil exploration in the region is the most likely culprit. According to a report from Peru 21, local fishermen in Lambayeque, north Peru, were first to notice the inexplicable rise in dead dolphin appearing on shore -- averaging roughly 30 per day. The Rapid Decline Of The Natural World Is A Crisis Even Bigger Than Climate Change. Nature is in freefall and the planet’s support systems are so stretched that we face widespread species extinctions and mass human migration unless urgent action is taken.
Chimps Have Their Own Cultures, And Humans Are Destroying Them. 9 Tons of Pangolin Scales Are Seized in Hong Kong. Amazing Tourist Attractions That No Longer Exist Because We've Destroyed Them. The Amazon is approaching a point of no return - but it's not too late. The world’s forests are shrinking.
For years, they’ve withstood a multitude of human impact. But according to a new study published in the journal Science Advances, they may be reaching a crisis point. If deforestation goes beyond 20 percent of its original spread, the Amazon Rainforest will have reached the “point of no return”. Palm oil boycott could actually increase deforestation – sustainable products are the solution. Palm oil can be found in food and cosmetics everywhere: in fact, half of the world’s population uses palm oil in food.
But public awareness about the loss of wildlife through deforestation caused by palm oil crops is growing, and there’s mounting pressure on retailers to reduce their sales of palm oil products, or boycott them altogether. Top 10 Most Polluted Rivers in the World Ravaging our Oceans Today! Advertisement. Hundreds of birds dead during 5G experiment in The Hague, The Netherlands. About a week ago at The Hague, many birds died spontaneously, falling dead in a park. You likely haven’t heard a lot about this because it seems keeping it quiet was the plan all along. However, when about 150 more suddenly died- bringing the death toll to 297- some started to take notice.
And if you are looking around that park you might have seen what is on the corner of the roof across the street from where they died: a new 5G mast, where they had done a test, in connection with the Dutch railway station, to see how large the range was and whether no harmful equipment would occur on and around the station. And harm happened, indeed. This is how long everyday plastic items last in the ocean. Depending on how thirsty you are, it might take you less than five minutes to swig back the contents of a plastic bottle.
But it takes the ocean 450 years to break down the plastic. This is the estimate from the US’ National Oceanic and Atmospheric Administration (NOAA) and Woods Hole Sea Grant, which compiled data showing the length of time for man-made marine debris to biodegrade in the sea. As the chart below shows, fishing line is the worst offender, taking up to 600 years to biodegrade, while disposable diapers will take as long as plastic bottles – 450 years – to break down. Plastic shopping bags will take up to 20 years to break down, while styrofoam takeaway coffee cups take 50 years, and cigarette butts take 10. Chroniclelive.co.

In the latest “oh my god, what are we doing to our planet” news, a recent lab-based study has shown human industrial activity is leading to ocean acidification that’s so severe it could be dissolving the seafloor in some parts of the ocean. The ocean really is our savior. It is the world’s biggest carbon sink, absorbing colossal amounts of carbon dioxide from the Earth’s atmosphere.
Without this service, the planet would have warmed 36°C (64.8°F) since the Industrial Revolution, as opposed to the 1°C (1.8°F) rise we are currently facing. Most of this absorbed carbon dioxide remains as dissolved carbon dioxide, but a small fraction reacts with the water to form carbonic acid. FN: Bevara biologisk mångfald annars dör vi också ut. China is Turning the Rainforest into Cheap Furniture for the U.S. U.S. consumers have long f, but little have we known the high price the global community has paid for it. Recent reports of Brazil’s new president’s plans to open up the Amazon rain forest to agriculture and mining have the world worried about the effects of deforestation on global climate change. The entire planet is dependent on these two major rainforests for sinking carbon dioxide and keeping global warming from spiraling out of control. In addition to potential climate catastrophe, China’s illegal deforestation of the Congo Basin is robbing local Africans of resources vital to their survival.
