Greenland is losing ice catastrophically

24.08.2020

The Greenland ice sheet, which is the second largest, lost a record 2019 billion tons of ice in 532. In July alone, 223 billion tons of ice melted.

For comparison, in 2003-2016, Greenland was losing 255 billion tons of ice per year. Last year, the glacier lost 15% of its ice than in 2012, when most of the shield also melted.

According to scientists, the water that melted in Greenland in 2019 could flood the entire territory of the UK by 2,5 meters.

Melting ice is linked to climate change. 2019 was the third hottest year since the 1880s, with temperatures in the Arctic also rising to record highs. Scientists believe that a constant increase in temperature, a small amount of snowfall, and cloudless skies led to a record melt. Because of this, more sunlight hit the glacier.

In 2017-2018, Greenland experienced a record amount of snow, and the summer was abnormally cold. But the temporary cooling did not save from record melting in 2019.

By the end of the century, only because of the melting of the glaciers of Greenland, the sea level will rise by 10 centimeters, but in general it is expected that by 2100 the water level will rise by a meter. This means that London, Shanghai, Hong Kong and the islands in the Pacific Ocean may be under water. 300 million people around the world could be affected.

Earlier, an international group of scientists said that since 2000, the rate of melting of the Greenland ice sheet has jumped sharply and the snow that falls does not have time to compensate for the losses. The researchers argue that this process can no longer be stopped.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Meteorites in limestone 21.10.2003

Large quantities of ancient meteorites have been found in several quarries in a vast limestone region in southern Sweden. This limestone accumulated from marine sediments over a period of about two million years, and appeared on land about 480 million years ago.

Meteorites lie in those layers that were formed 500 million years ago. The intensity of meteorite fall is now low: on average, one event per year for every 12,5 thousand square kilometers of the Earth's surface. Half a billion years ago, judging by the Swedish find, meteorites fell a hundred times more often. Astronomers suggest that then some powerful collisions occurred in the asteroid belt, as a result, a large asteroid broke up into separate stones and some of its fragments fell to Earth.

Now scientists intend to examine similar deposits of the same period in China and South America.
