Climate change has had a significant impact on the world in 2019



Earth is now the warmest when it's been around for 120,000 years. Eighteen last 19 years were the warmest on record. And the concentration of carbon dioxide – a powerful greenhouse gas – is likely to be the highest in 15 million years.

The consequences of such a globally disturbing climate are many, and this is understandably difficult to trace. In order to help, here is a list of news-critical news climate that emerged in 2019 from historically unprecedented ice disappearance to flood-stricken cities.

  Carbon dioxide emissions from air transport increased in 2018.

In early 2019, the Rhodium Group, a research agency analyzing global economic and environmental trends, published a report that in 2018, carbon dioxide emissions in the United States grew by 3.4% comparatively with the previous year. This is the second largest increase over the past two decades.

"This trend in the wrong direction is not encouragement," said Robert McGrath, director of the Colorado Institute for Renewable and Sustainable Energy at the University of Colorado, who had no role in the report, but considered it.

Antarctica – the birthplace of the world's largest ice shields – does not just melt much faster than it was a decade ago. Large massifs of ice, which scientists believed were largely immune to melt, lose enough ice in the sea.

"People are beginning to realize that East Antarctica can wake up," said Josh Willis, oceanographer at NASA's Jet Propulsion Laboratory.

"There is growing evidence that eastern Antarctica will not just remain frozen and behave well during the next 50-100 years," he explained.

A triple blow from diseases, climate change and deforestation threatens about 60% of wild coffee species of the planet. Although it still does not threaten the global supply of coffee, it endangers the stability of your favorite coffee before deep planetary changes.

"As farmers are increasingly exposed to new climatic conditions and pest pressure changes, the genetic diversity of wildlife relatives may be important for the emergence of new varieties of coffee that can withstand these vices," Nathan Muller, associate professor at the Department of Earth Systems at the University of California, Irvine, who explores global food security, said by e-mail.

Whirlwind became a popular phenomenon for a valid reason: this weakening of the polar vortex and the subsequent spread of cold air has become more widespread over the past two decades.

"We see that these occur more often, n but recently, "said Jeff Weber, a meteorologist at the University of the Atmospheric Research Corporation.

Although this increase in the frequency of polar vortices is a hot spot in the research that occurs, there is a significant reduction in Arctic sea ice. The Arctic warms up more than twice as fast as the rest of the earth bullets and sea ice cover falls. As a result, recent climatic studies show that – without this ice cover – more heat comes from the oceans. In the end, the researchers found that this relatively warm air interacts and weakens the winds over the Arctic, allowing the cold polar air to escape more easily to southern locations such as Cleveland and New York.

In addition to the increasingly dark news from the north and south poles, the melting of the "third pole", known as the Hindu Kush Himalayas, takes place. Spreading more than 2000 miles in eight countries (from Afghanistan to Manganese), these mountainous lands are home to the world's third largest stock of ice on the planet and provide hundreds of millions of people with water.

In the most optimistic conditions it turned out that more than a third of the ice would disappear by the end of the century. But in more extreme climate scenarios where global climate control efforts fail, two-thirds of these powerful glaciers may disappear, and overall ice losses will be 90%.

"The wise glacier is not a great story," said Joseph Shey, one of the leading authors of the report and associate professor at the Department of Environmental Geomatics at the University of North British Columbia, in an interview.

In early 2017, the Trump administration tried to blow up the orbiting Observatory 3 or OCO-3. This did not work. Then, again in 2018, the White House sought to stop the instruments of earth science.

Again, the spacecraft with the size of the refrigerator was kept.

Now SpaceX intends to launch OCO-3 to the International Space Station in the coming months, already on April 25th. Using a long robotic hand, the cosmonauts will add the OCO-3 to the edge of the space station, allowing the tool to look at the Earth and measure the concentration of carbon dioxide accumulated on the planet – a powerful greenhouse gas.

"Dioxide of carbon is the most important human gas released into the atmosphere," said Henry Eldering, a researcher at OCO-3 in NASA's Jet Propulsion Laboratory.

As a climate scientist Simon Donner, who explores climate-induced climate change at the University of British Columbia, highlighted through the list posted on Twitter 20 of the coldest years of the planet occurred almost a century ago, between 1884 and 1929.

The coldest year was recorded in 1904.

Two NASA satellites observed how the Earth grew greener over the past 20 years – largely because China has been distributing millions of trees.

Planting the Earth – that is, increasing the area covered with green leaves – has achieved the greatest successes in China and India since the mid-1990s. "The effect is mainly due to ambitious tree planting programs in China and intensive agriculture in both countries," he said.

China began mobilizing tree planting in the 1990s to combat erosion, climate change and air pollution.

The scale of a green new course – if such a program really corresponds to the scale of the original "New Year" – it's not just pushing millions of Americans to work, but it can well turn the mood, the culture and spirit of the United States in the 21st century.

The new course not only paid people to build things. People performed work that improves the nation. They planted three billion trees. They built many bridges and roads of the nation. Today, we ride under their tunnels and walk in their parks.

"Those people at the end of their lives will take their seven days ago to show them what they did – because they were very proud of it," said Gray Brechin, a historian geographer and scholar of the New Deal.

 Higher concentrations of CO2 spin around the Earth (shown in yellow and red)

Higher concentrations of CO2 are spinning around the Earth (shown in yellow and red). William Hupper was elected chair of the new Presidential Committee on Climate Safety, according to The Washington Post . Hopper argues that the atmosphere of the planet needs much more CO2, a powerful greenhouse gas that has been repeatedly emphasized by the US government – the government – and the grip of independent scientists – is accelerating climate change

. "More CO2 is actually beneficial to the Earth," states that the Earth is experiencing a "CO2 famine", and came to the conclusion that "if the plants could vote, they would vote for coal."

"The idea that the increase in CO2 is universal [to plants] is very false," said Jil Anderson, an evolutionary ecologist specializing in plant populations at the University of Georgia.

The Russian river, passing through the city of Hernovil, in the district of Sonoma, reached a height of 45 feet and flooded the area, forcing the sheriff to tell Twitter that the city was surrounded by water – without the exit or exit. Although California relies heavily on these winter atmospheric rivers for their water, scientists expect these storms to skyrocketed, as the Earth's climate warms up.

"We are likely to see rain in increasingly intense bursts," said Daniel Sueen, a climatologist at the National Center for Atmospheric Research.

Sunlight reflected from Earth

Solar geoengineering is widely regarded as a risky business. Several science fiction concepts – using airships, airplanes or other means to load the earth's atmosphere with particles or droplets that reflect sunlight and cool the planet – has shifted to the main conversation as a tool that changes the tireless climate change, should our efforts to reduce emit carbon dioxide, fail or spray. But the schemes of geoengineering come with many dangers. A number of studies have cited the bad effects of sun-earth intervention, including large crop losses, the probability of unforeseen negative side effects, and a critically weakened water cycle that can cause precipitation and widespread drought

. However, new research published in the journal Nature Climate Change acknowledges these problems, but finds a potential correction: only deploying a sufficient amount of reflection points in the atmosphere to reduce about half the warming of the Earth, rather than relying on geoengineering to fully turn the Earth in the cooler, which is the 19th-century climate. In other words, giving the Earth a dose of geoengineering, which can change a significant part of the warming, but not enough to raise the problem side effects.

"Solar engineering can not be a good choice in an emergency," said David Kate, a researcher at Solar Engineering at Harvard University and co-author of the study.

Without the benefit of herself, the Earth The huge sea swallowed about 30% of carbon dioxide emitted into the Earth's atmosphere during the last century. Critically, scientists have now confirmed that the ocean in the past decades has continued a steady pace of absorption of CO2, and not giving a powerful greenhouse gas to saturate the sky even more.

But the difficult question still emerges: How long can we rely on the ocean to save carbon dioxide effectively and significantly reduce global warming?

"At some point, the ability of the ocean to absorb carbon" will begin to decrease, "said Jeremy Mathis, climate scientist at the National Oceanic and Atmospheric Administration (NOAA) climate." This means that atmospheric CO2 levels can grow faster than it already is. "

" This is a big deal, "emphasized Mathis.
