Rising Arctic temperatures will impact global economy. Scientists monitor Arctic transformation under climate change
Scientists from the Vernadsky Institute of Geochemistry and Analytical Chemistry (GEOKHI RAS) have discovered a harmful increase in the biological productivity of remote Arctic lakes due to global warming. Scientists have discovered plumes of smoke that periodically appear in the vicinity of Bennett Island in the East Siberian Sea. This may indicate the presence of an active volcano and a tsunami threat to Arctic villages in Yakutia. As the ice melts, new shipping routes will appear, changing the global economy. Rapidly rising temperatures and melting ice in the Arctic will affect international shipping and coastal communities around the world.
Melting polar ice caused by climate change is redistributing the Earth’s mass and increasing the length of the day
Researchers used more than 120 years of data to understand how melting ice, depleting groundwater and rising sea levels are shifting the planet’s rotation axis and lengthening the days.
Climate is changing the Earth’s flora and water bodies
Decreasing oxygen levels in water pose a critical threat to nature and society on Earth. On average, lakes around the world will experience unprecedented climate conditions by the end of this century. Warming Arctic regions are causing toxic algae blooms. A NASA study found that tundra vegetation will be taller and greener by 2100.
The Arctic and Antarctica continue to melt rapidly, revealing ancient things hidden beneath the ice
The Arctic is warming faster than anywhere else on Earth. Ice and snow are melting, and Arctic sea ice is thinning and retreating. This means that algae living on the bottom of the sea ice are getting more sunlight, leading to an annual summer bloom once there is enough light. Erebus, located on Antarctica’s Ross Island (separated from the mainland by McMurdo Sound), is the southernmost active volcano on Earth; the second-tallest on the sixth continent, at 3,794 metres.
Global warming will allow species of flora and fauna to colonize previously uncharacteristic territories
In Russia, it was revealed that the fauna of Siberia is becoming more southern due to climate change. Global warming will allow tropical species from the Atlantic to colonize the Mediterranean Sea. Global warming is making some species of marine animals more susceptible to the spread of diseases such as avian influenza due to the animals congregating in breeding and feeding areas or changing migration patterns. Some researchers are concerned that current rates of warming could make oceans as warm and acidic as they were during the end of the Permian extinction, 250 million years ago, when up to 90 percent of marine species died out.
New natural sources of greenhouse gases and associated climate control technologies
Layers of methane are locked under permafrost in Arctic regions, but if they were released it could cause problems for the rest of the world. Researchers also discovered intense methane emissions deep in the Baltic Sea. Methane can be a real problem for the environment. The greenhouse gas, made up of carbon and hydrogen and about 80 percent more potent than carbon dioxide, occurs naturally in sedimentary layers of the seafloor and is responsible for about 30 percent of global temperature rise.
The Government of the Russian Federation has approved an action plan for adaptation to climate change. February was the warmest on record
The message on the approval of the national action plan for the second stage of adaptation to climate change was published on the website of the Government of the Russian Federation. February 2024 on Earth became the warmest on record. Sea ice on both the top and bottom of the planet continued to decline in 2024.
The Arctic could become ice-free in the 2030s, Antarctica and Greenland are melting at record rates
The Arctic will be ice-free within a decade during the summer months. A new study from the University of Colorado Boulder says the Arctic could become ice-free in August or September as early as the 2020s or 2030s. The Arctic could then remain ice-free for nine months of the year, as predicted by worst-case climate scenarios. This is largely due to the fact that sea ice, which reflects solar radiation, melts into the open ocean, which absorbs solar radiation.
Melting permafrost could release nuclear waste and pathogens
A team of scientists has discovered that thawing permafrost could release a dangerous legacy of the Cold War – nuclear waste that is still radioactive. In addition, the release of pathogenic microorganisms is possible, reports Nature Climate Change. Melting Arctic glaciers could release radioactive waste from Cold War-era nuclear submarines and reactors. The Arctic’s nine million square miles of ice have been accumulating for more than a million years a variety of substances that could be released into the air and water due to climate change.
Global warming has accelerated 4 times compared to expectations and the Paris Agreement
Faster warming in the Arctic will result in a global temperature rise of 2° being reached 8 years earlier than if the region had warmed at the global average, UCL researchers have found. The Arctic is currently warming almost 4 times faster than the global average.
The Arctic, Antarctica and Greenland have received special attention from organizations involved in space research
The Russian satellite constellation Arktika-M, launched in 2021 and 2023, transmitted the first images of the Arctic region and surrounding areas from space. On June 30, 2011, NASA’s Terra satellite made several passes over the Arctic. ICESat-2 is the second spacecraft to study the Earth’s ice cover. The US-India satellite NISAR will begin monitoring changes in the Earth’s frozen regions in 2024.
Anomalous temperatures were simultaneously recorded in the Arctic and Antarctica
Simultaneous significant warming was recorded at the North and South poles of the planet – the temperature at the Antarctic Concordia station, located at an altitude of 3234 meters above sea level, reached −12.2°C the day before, which is 40°C above average.
Warming continues to accelerate on its own
The accumulation of sea salt and the seepage of warm, salty seawater under ice sheets as glaciers melt accelerate the warming process.
A database of the sea coasts of the Russian Arctic has been created, and plans include a digital model of the World Ocean
More than sixty percent of Russia is permafrost zone. More than 15 million people live in this territory, and there is an infrastructure developed that is not found anywhere else in the world on permafrost soils.
Global warming is accelerating itself
On the Pacific islands, entire cities are retreating inland under the pressure of water. Melting permafrost is changing landscapes, destroying animal habitats, releasing carbon and releasing dangerous microorganisms that have been trapped in the ice for millennia.
Melting glaciers reveal unknown species and meteorite remains
Glaciers are capable of preserving information about the history of the Earth, as they trap dust particles, traces of gas, microbes and plant matter from the environment.
Tropical Pacific heat waves spread to mid- and polar latitudes
Abnormal July 2021: record heat in the Northern Hemisphere and record cold in the Southern Hemisphere of the Earth.
Researchers predict methane explosions, fires and thunderstorms in the Arctic and tundra
Methane explosions can affect the climate of the entire planet. Hundreds of millions of tons of methane may be hidden under the ocean floor, which is currently contained by the “cap” of the permafrost zone.
By the middle of the 21st century, Arctic ice may completely melt in summer
The planet’s “refrigerator” has broken down. The Arctic Ocean will be completely free of summer ice by 2030. This assumption was put forward by scientists in connection with the noticeable warming of the Arctic Ocean and the melting of Arctic ice.
