Solar activity cycles have stumped scientists around the world, and research continues
When the current solar cycle began in late 2019, experts from the Space Weather Prediction Center (SWPC), which includes scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA), predicted that solar maximum would likely begin sometime in 2025 and would be comparable to the previous, weaker cycle. However, as the current cycle progressed, it quickly became clear that this was not the case, and that solar maximum would occur earlier and be much more intense than initially anticipated.
The shallowing of the Caspian Sea is a dangerous environmental problem for many Eurasian countries
According to the Federal Agency for Fisheries, the Caspian Sea’s water level has dropped by nearly 2.4 meters since the mid-1990s. The coastline and aquatic bioresources are experiencing colossal external impacts. As a result, populations of entire species, including the Caspian seal, could disappear. The Caspian Sea is the largest enclosed body of water on Earth. Over 130 rivers flow into it, the largest of which are the Volga, Ural, Terek, Sulak, and Samur. Five countries are located on the Caspian coastline: Russia, Kazakhstan, Turkmenistan, Azerbaijan, and Iran. In 2023, a local emergency was declared in the Aktau region of Kazakhstan due to the rapid shallowing of the Caspian Sea, caused by a decrease in river inflow. This created problems for the local port and fishermen.
Drought and widespread desertification exacerbate poverty, hunger, energy insecurity and ecosystem destruction
According to a new UN-supported report, some of the most severe and devastating droughts in human history have occurred since 2023, driven by climate change and ongoing pressure on land and water resources. The report, “Global Drought Hotspots 2023–2025,” provides a comprehensive account of how droughts exacerbate poverty, hunger, energy insecurity, and ecosystem destruction.
The benefits and harms of the Earth’s ozone layer. The ozone hole in Antarctica is steadily shrinking
Countries are doing the right thing by continuing to ban chemicals called CFCs and HCFCs, which deplete the ozone layer above Earth. However, while this helps restore the protective ozone layer, scientists have found that restoring the ozone layer will lead to greater global warming than originally thought. Air pollution from vehicles, factories, and power plants also degrades the ozone layer near the Earth’s surface, causing health problems and warming the planet.
Coastal cities are predicted to be at risk of flooding by the end of the century
An oceanographer has warned of a possible rise in global sea levels of up to 1.3 meters by 2100. According to another new study, published in the journal Urban Sustainability, unless fossil fuel emissions are rapidly reduced, rising sea levels could put more than 100 million buildings at risk of regular flooding.
Geological age of planets: scientists reveal secrets of its determination
Recent advances in geochronology, or rock dating, allow geologists to measure radioactive decay and assign very precise absolute ages to geological events. In another study, scientists found isotopic evidence of a sudden switch to primitive plate tectonics dating back about 3.8 billion years. The discovery suggests that a simple form of subduction had begun at least in one place on the planet by that time. And a tree-lined African lake has provided data on the Earth’s magnetic field for the past 150,000 years.
New research describes how the Earth’s surface moves, the speed of Earth’s plates and the history of their movement
Earth’s plate tectonics traced back to a “tipping point” 3.2 billion years ago. The Earth’s surface is constantly changing today, with tectonic plates shifting and moving, forming mountain ranges, ripping apart the seafloor, and causing massive earthquakes. Geophysicist Dave Stegman of the Scripps Institution of Oceanography in La Jolla and colleagues used observational data and computer models to develop a new formula for how the speeds of Earth’s plates depend on the size and edges of subduction zones. About 200 million years ago, the continent of Pangea broke apart into two huge pieces, with the supercontinent Laurasia to the north and Gondwana to the south.
The Indian, Eurasian and Arabian continental tectonic plates are still converging and active
The massive tectonic collision that is causing the Himalayas to rise could also split Tibet apart, with the Indian Plate potentially breaking in two, sliding under the Eurasian Plate and tearing Tibet apart. The colorful swirls and streaks that characterize China’s Rainbow Mountains would go unnoticed if not for the massive tectonic collision that created the Himalayas. Also, the Arabian and Eurasian Plates are still converging, and recent research suggests that a chunk of oceanic crust that separated the two plates before they collided is now being torn apart under Iraq and Iran.
Different types of plankton have significantly changed the ocean’s color over the past two decades
The color of the Earth’s oceans has changed significantly over the past two decades, and these changes are the result of human-induced climate change. They cannot be explained by natural variability alone, and they affect more than 56 percent of our planet’s oceans, which is more than the total land area on our planet. At the same time, there has been an increase in the number of plankton species Noctiluca scintillans, which is destroying marine ecosystems by depleting oxygen and changing the shape of the food chain.
Antarctic and Atlantic currents weaken, La Niña delayed, scientists discover new ocean currents
Antarctic currents, which supply 40% of the world’s deep oceans with nutrients and oxygen, are slowing dramatically. These deep ocean tides supply nearly half the world’s oceans with vital nutrients and oxygen, but melting ice shelves are slowing them. Currents in the Atlantic Ocean are also weakening — which could make the climate in some regions unrecognizable. And a newly discovered body of water called Atlantic Equatorial Water stretches from Brazil to West Africa.
Acid zone could make up half of the world’s oceans by the end of the century
At 13,000 feet below the ocean’s surface is an acidic zone, and it’s growing. The carbonate compensation depth—the zone where high pressure and low temperatures create conditions so acidic that they dissolve shells and skeletons—could comprise half the world’s oceans by the end of the century. At the same time, declining oxygen levels in the water pose a critical threat to nature and society on Earth.
Oceanographers have explored the area around the Nazca Ridge in the Pacific Ocean and discovered a huge underwater mountain
Oceanographers led by the Schmidt Ocean Institute exploring the depths of the Pacific Ocean discovered a huge seamount in September 2024. The 3,109-meter-high seamount is a major find. It is one of many discoveries made during a 28-day survey in late summer by oceanographers on the research vessel Falkor. But satellites are no less important in exploring the ocean depths — satellites are mapping the Earth’s ocean floor in unprecedented detail.
Scientists have discovered an ancient ocean floor between the Earth’s mantle and outer core
A University of Alabama-led study has previously been seen as only a hint, but it shows that ancient ocean floors may have spanned the entire core-mantle boundary. If the new earthquake data is correct, we will need to add another layer to our understanding of the Earth. This layer, which fits neatly between the Earth’s mantle and outer core, is thought to be an ancient ocean floor that now reconstructs our view of the core-mantle boundary.
Sea levels rose faster than expected in 2024
A NASA analysis showed a surprising rise in sea levels in 2024. Last year’s rise was driven by unusually strong ocean warming combined with the melting of land ice such as glaciers. As a result, Hawaii, for example, is sinking 40 times faster than scientists had previously thought, with some parts of the island chain sinking at a rate of 0.6 millimeters per year, but others are in much worse shape.
36 Ways to Stop Global Warming
In recent years, scientists have proposed many ways to curb global warming, such as: spraying diamond dust, working with glaciers, reflecting sunlight, alternative energy, and working with human and farm waste.
How to escape from heat and other climate changes? Think about it right now
We offer for your consideration modern and ancient architectural solutions: smart windows, green spaces and special buildings.
Deadly Heat: Global Organizations Sound Alarm
Over 20 years, heat-related mortality has increased by 30%. In July 2024, more than 120 people died from heatstroke in the Tokyo metropolitan area. Climatologists and doctors have found that heat waves in Europe in 2023 caused the death of over 47.6 thousand residents of all 35 European countries between June and October 2023. The number of heat-related deaths in Europe could triple by the end of the century.
The number of fire-hazardous days on Earth has doubled, and the rate of spread of forest fires is increasing
Melting permafrost will cause an increase in the number of forest fires. Also, the number of fire-hazardous days on Earth has doubled, and the speed of forest fires is increasing.
Researchers have documented the destruction of infrastructure due to climate change and extreme weather conditions
In January 2025, the largest fire in U.S. history occurred. Other infrastructure destruction is linked to the land sinking in cities — a study by NASA and NOAA found that California is sinking in some areas: The rising and falling of the land, which the researchers called “vertical land motion,” is caused by natural processes like the movement of tectonic plates, according to the study. Then, according to a new report from The New York Times, bridges are under unprecedented stress due to climate events, including extreme temperatures, increased flooding, and severe soil erosion. And finally, rat populations are growing in cities around the world due to climate change.
Climate change is changing the policies of states
Switzerland and Italy have redrawn their Alpine border as glaciers melt, with changes affecting the area around the Matterhorn, one of Europe’s highest peaks, which borders the Swiss region of Zermatt. At the same time, richer countries are starting to pay poorer ones for the damage caused by climate change.
Scientists have recorded a slowdown and change in ocean currents
Antarctic currents, which supply 40% of the world’s deep oceans with nutrients and oxygen, are slowing dramatically. Other models show the Gulf Stream is weakening and the AMOC could be close to collapse, with serious implications for climate. The Italian findings suggest that current modeling used to track the flow of sediment and pollutants in the deep sea and reconstruct ancient ocean conditions needs to be updated.
The world is seeing a sharp drop in fresh water levels and rising sea levels
The Earth’s sea levels are rising, damaging the livelihoods and infrastructure of coastal communities around the world. Agencies and organizations are working to prepare people for the changing world around them. An international team of scientists, using observations from NASA-German satellites, has found evidence that the total amount of fresh water on Earth has dropped sharply since May 2014 and has remained low since then.
Mars’ gravitational pull may influence Earth’s climate
Every 2.4 million years, Mars tugs on Earth so hard that it reshapes the ocean floor. New geological research suggests that Mars’ gravity pulls Earth closer to the sun in cycles lasting millions of years, warming our climate.
Melting permafrost triggers release of hazardous gases from deep underground sources
A new physics model suggests that meltwater from thawing permafrost on Russia’s Yamal Peninsula could release methane gas sources at depth, causing explosions that create huge craters on the surface. Meanwhile, thawing permafrost in the Arctic could release cancer-causing radioactive radon. And off the coast of Alaska, the U.S. Coast Guard says an underwater volcano-like structure is spewing gas.
NASA Analysis Shows Irreversible Sea Level Rise in Pacific Islands
NASA analysis shows irreversible sea level rise in Pacific islands as climate change rapidly changes a region of the world home to millions of people. Over the next 30 years, Pacific island nations such as Tuvalu, Kiribati and Fiji will see sea levels rise by at least 6 inches (15 centimeters), according to an analysis by NASA’s Sea Level Change Science Group. That level of rise would occur regardless of whether greenhouse gas emissions change in the coming years.
Satellite data proves climate change is a climate crisis
ESA’s Sentinel-1 detects retreating Arctic glaciers. As Arctic temperatures rise, glaciers that end at sea, particularly in places like Svalbard, are retreating rapidly and calving at a rapid rate. Arctic sea ice has also retreated to near-historic minimums in the Northern Hemisphere this summer, according to NASA and the National Snow and Ice Data Center (NSIDC).
Redistribution of the Earth’s water balance – desertification of southern Russia and Europe and filling of lakes in deserts
The director of the Potsdam Institute for Climate Impact Research warned that precipitation, the source of all fresh water, can no longer be relied upon: the global water cycle has been disrupted for the first time in human history. Russian scientists have warned that deserts are gradually taking over southern Russia. Jim Skea, chairman of the UN Intergovernmental Panel on Climate Change, said that deserts could appear in southern Europe; climate change has intensified droughts in Europe. Their formation will be caused by global warming. Satellites have taken photographs showing how the sands of the Sahara Desert are filling with water.
Climate change is having a detrimental effect on marine life
Climate change is affecting salmon migration. Coral die-offs off Australia in the summer of 2024 are linked to rising Pacific temperatures. The world’s largest and most devastating sponge die-off has been recorded off New Zealand. Global warming will reduce the survival rate of shark embryos during spawning by up to eight times. The University of California Institute of Marine Science, along with a large team from other institutions, has created early warning systems that predict where marine heat waves (MHWS) will occur.
30 previously unknown species of invertebrates and insects discovered on thawed glaciers of the Central Caucasus
Scientists have discovered 30 previously unknown species of invertebrates and insects in areas of the Central Caucasus glaciers that have thawed due to global warming. According to the press service of the Institute of Geography of the Russian Academy of Sciences, a total of 438 species of invertebrates live in the areas studied.
Cases of bears approaching people have become more frequent
One of the most pressing issues in the Arctic today is recognizing a bear’s entry into a populated area as an emergency. As with any other natural disaster, residents at such a time are unable to leave their homes and cannot work, since predators can be quite aggressive. At the same time, without declaring an emergency, the municipality cannot mobilize all possible resources. So, if in one part of the village residents understand that a polar bear has arrived, there is no way to notify the other part. Without certain permits, the heads of the municipality do not even have the right to turn on the warning system.
Deer and antelope have recently significantly expanded their habitat
Reindeer are expanding their range northwards. This could harm some species, such as the northern caribou. In recent decades, Taimyr reindeer and geese have significantly changed the timing and nature of their movements. Researchers have also recorded the largest wildlife migration in the world in eastern South Sudan.
Birds are changing their behavior and activities due to climate change
Climate change is preventing birds from reproducing. Scientists have already found out that changes in natural and climatic conditions have a negative impact on the population of seabirds. Accelerating trends in climate change on the planet are confirmed by new patterns in the behavior of animals and birds of Western Taimyr. New studies show that increasing tropical storms threaten seabirds. Southern birds and spiders get to the Arctic through “corridors” that have appeared due to the melting of permafrost.
The eruption of one small volcano can affect the climate of the Earth’s hemisphere for a couple of years
Antarctica is dotted with volcanoes, waiting to erupt. And a volcano in Tanzania and volcanoes in Iceland are close to erupting. The Tonga eruption, which released 150 megatons of water vapor into the stratosphere, affected the atmosphere for years. Satellite data suggests that a volcano in Tanzania, which spews extremely fluid lava, may be close to erupting. Iceland is threatened by uncontrolled volcanic eruptions due to climate change.
Spain suffered from DANA
The rushing water turned narrow streets into death traps and created rivers that tore through homes and businesses, sweeping away cars, people and everything else in their path. The floods destroyed bridges and left roads unrecognizable. With record-breaking temperatures across the Mediterranean and a year’s worth of rainfall in a matter of hours, Spain was hit by a weather phenomenon known as DANA. A freak weather phenomenon known as DANA caused catastrophic flooding in Valencia, Spain in late October 2024. More than 155 people were killed and dozens more were missing in what meteorologists are calling one of the worst natural disasters in recent memory.
The tsunami impacts in Russia include coastal areas of Kamchatka, the Kuril Islands, Sakhalin Island and Primorye
Climate change could trigger giant, deadly tsunamis from Antarctica, a new study warns. Sediment shifting beneath the Antarctic seabed could trigger giant tsunamis due to rising ocean temperatures. Fourteen cities and dozens of towns in Russia are vulnerable to tsunamis across three regions of the Far East, with powerful waves capable of hitting their coasts at speeds of up to 1,000 kilometres per hour.
The day before the earthquake in Primorsky Krai, the water receded from the shore by several tens of meters
Residents of Primorye noticed the strongest low tide in recent times on October 20, which is especially visible in closed bays and gulfs. An earthquake with a magnitude of 4.4 was recorded near Nakhodka, the earthquake occurred on October 21. Heavy and prolonged precipitation can intensify earthquakes.
The Earth’s Crust Doesn’t Stop – Scientists Discover Old and New Continents
Scientists have discovered an unexpected new continent hiding beneath Greenland. Zealandia, thought to be a candidate for Earth’s eighth continent, has been almost completely submerged by the sea. The new ocean could split Africa into two continents. Doggerland: Before it was inundated by a tsunami 8,000 years ago, this landmass connected Britain and continental Europe. Archaeologists and citizen scientists have discovered a number of artifacts from Doggerland over the years, including a deer bone with an arrowhead and a fragment of a human skull.
Massive floods, fires that have killed dozens of people are caused by global climate change
Massive floods that have engulfed Poland and Central European countries and caused the deaths of dozens of people are caused by global climate change, as are other similar cataclysms around the world, said Nobel Peace Prize laureate and former adviser to the UN Secretary-General on climate change Rae Kwon Chung. Record fires have engulfed South America, bringing black rain, green rivers and toxic air to the continent. Drought and prolonged heat have caused forest fires in the Bryansk region of Russia. At least 503 people have died in Chad as a result of floods, as of September 24. Coastal flooding due to high tides is becoming an increasingly common occurrence in most parts of the United States.
The current year 2024 has broken the heat records of the previous year
NASA considers the summer of 2024 to be the hottest to date. July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record temperatures are part of a long-term warming trend caused by human activity, primarily greenhouse gas emissions. Crimea recorded its hottest day on record.
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.
The southernmost continent, Antarctica, is warming and blooming
The remains of a 90-million-year-old rainforest have been discovered beneath the ice of Antarctica. Now, warmer temperatures are melting glaciers and the meltwater is allowing seeds to begin to germinate. Antarctica is in the grip of one of the world’s fastest climate changes. Its melting ice could contribute to sea level rises of up to 5 metres. Where the ice disappears, it leaves behind barren land. By the end of this century, land the size of a small country could emerge from beneath the ice. Antarctica’s Thwaites Glacier has earned its nickname “Doomsday Glacier” for its potential to flood coastlines around the world if it collapses.
Melting Glaciers: Andes, Altai, Alps and China May Be Completely Ice-Free
Isotopic analysis of rocks near the Andes glaciers has shown that these glaciers have become smaller than at any time in the Holocene, which indicates significant warming in the tropics. Scientists have recorded a violent bloom of blood-red algae Chlamydomonas nivalis on glaciers in the Altai Mountains this year, which leads to their more active melting and may be an indicator of climate change. Small glaciers in northwest China will disappear by the middle of the 21st century. The China Daily newspaper, citing local scientists, reports that the disappearance of glaciers is inevitable, and this should be expected “regardless of the climate scenario and the amount of precipitation.”
Land degradation and desertification associated with climate change are observed worldwide
The Volgograd Region in the Russian Federation has been named one of the most desertified territories in Russia. In just a few years, West Africa, South Asia, and the Midwest of the United States will become dangerous to human life due to climate change. Having analyzed data on climate change and abnormal heat waves on Earth, scientists have modeled temperature fluctuations for the coming years and have come to disappointing conclusions for certain regions of the planet.
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.
Solar flares and magnetic storms pose a real danger
About once every thousand years, Earth experiences an extreme solar event that can cause severe damage to the ozone layer and increase ultraviolet (UV) radiation levels at the surface. Over the past century, the north magnetic pole has moved across northern Canada at about 40 kilometers per year, and the field has weakened by more than 6%. Geological records show that there have been periods of centuries or millennia when the geomagnetic field was very weak or even absent.
Solar flares continue to break records
NOAA Is Rewriting the Book on How to Rank Solar Storms: The Capabilities, the Science, and Our Understanding of the Science — A lot has changed in space weather in the last 25 years. Technology has improved, and scientists have learned more about extreme space weather events from historic geomagnetic storms like the Halloween solar storm of October 2003 and the Gannon Event of May 2024. Looking to the future, scientists at the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center (SWPC) are now looking for ways to better inform the public about space weather events that can impact Earth. That’s why NOAA is asking the public for input on how to rewrite its space weather scales.
What are Hurricanes? Rescue and Evacuation Plan. Latest Hurricane and Storm News
The shift from El Niño to La Niña has made for longer, more severe hurricane seasons. This year’s hurricane season will be stronger than average, forecasters warn. The Atlantic and Pacific hurricane seasons bring a host of dangerous weather, from blistering winds, torrential rains, power outages, and flash flooding. And with climate change linked to increased hurricane intensity, those impacts could continue to worsen.
