The threat of seafloor methane eruptions

Arctic sea ice volume

Arctic sea ice volume remains at a record daily low, as it has been for more than a year. The image below shows Arctic sea ice volume through November 2, 2025.


The image below shows monthly Arctic sea ice volume in the past 25 years. Markers show April (blue) and September (red) volume, corresponding with the year's maximum and minimum. In 2025, Arctic sea ice reached a record low maximum volume as well as a record low minimum volume.

[ from earlier post ]
Warmer water flowing into the Arctic Ocean causes Arctic sea ice to lose thickness and thus volume, diminishing its capacity to act as a buffer that consumes ocean heat entering the Arctic Ocean from the North Atlantic. This means that - as sea ice thickness decreases - a lot of incoming ocean heat can no longer be consumed by melting the sea ice from below, and the heat will therefore contribute to higher temperatures of the water of the Arctic Ocean. The danger of this is described in the screenshot below.

Global sea ice extent

The image below shows that the standard deviation from 1981-2010 of the global sea ice extent was -7.02σ on November 1, 2025, which is remarkable given the absence of El Niño conditions in 2025.

Low sea ice extent means that less sunlight gets reflected back into space and instead gets absorbed by the sea surface, resulting in higher sea surface temperatures. 

Sea surface temperature

The image below shows the standard deviation from 1951-1980 of the monthly sea surface temperature through September 2025, when it was 8.045σ. The image also shows that the deviation in August 2023 was 10.148σ. 


In statistics, the empirical rule states that in a normal distribution, 68% of the observed data will occur within one standard deviation (1σ), 95% within two standard deviations (2σ), and 99.7% within three standard deviations (3σ) of the mean. A 4σ event indicates that the observed result is 4 standard deviations (4σ) away from the expected mean. In a normal distribution, 99.993666% of data points would fall within this range. The chance for data to fall outside of 4σ is thus infinitesimally small.

The sea surface temperature anomaly versus 1951-1980 in the north mid latitudes (inset) reached a record monthly high of 1.657°C in August 2025, as illustrated by the image below.

[ from earlier post ]
Currently, sea ice is low at both poles. The low global sea ice extent at this time of year spells bad news for Antarctic sea ice, which typically reaches its minimum extent in February.

An Antarctic Blue Ocean Event (sea ice approaching a low of one million km²) threatens to occur in February 2026, triggering an Arctic Blue Ocean Event later in 2026 while the upcoming El Niño is strengthening. All this increases the danger that massive amounts of methane will erupt from the seafloor in 2026, further accelerating the temperature rise.

The methane danger


The methane danger is further illustrated by the images above (hourly methane) and below (monthly methane), adapted from images issued by NOAA November 2, 2025, showing methane averages recorded at the Barrow Atmospheric Baseline Observatory (BRW), a NOAA facility located near Utqiaġvik (formerly Barrow), Alaska, at 71.32 degrees North latitude.


Climate Emergency Declaration

UN secretary-general António Guterres recently spoke about the need for “a credible global response plan to get us on track” regarding the international goal of limiting the global temperature rise. “The science demands action, the law commands it,” Guterres said, in reference to a recent international court of justice ruling. “The economics compel it and people are calling for it.”

What could be added is that the situation is dire and unacceptably dangerous, and the precautionary principle necessitates rapid, comprehensive and effective action to reduce the damage and to improve the outlook, where needed in combination with a Climate Emergency Declaration, as described in posts such as this 2022 post and this one and as discussed in the Climate Plan group.

Antarctic sea ice area reaches record daily low

Antarctic sea ice area remained at a record daily low on October 24, 2025, following a record daily low on October 23, 2025. Antarctic sea ice area was 12.40 million km² on October 24, 2025, a deviation from 1981-2010 of -3.57σ, as illustrated by the image below.

The above image also shows that Antarctic sea ice reached a record low area of 1.09 million km² on February 24, 2023, close to a Blue Ocean Event and corresponding with a deviation of -2.86σ, i.e. smaller than the deviation of -3.57σ reached recently (on October 23, 2025).

Global sea ice extent

Low sea ice extent means that less sunlight gets reflected back into space and instead gets absorbed by the sea surface, resulting in high sea surface temperatures. Currently, sea ice is low at both poles. The low global sea ice extent at this time of year spells bad news for Antarctic sea ice, which typically reaches its minimum extent in February. 

The image below shows that the standard deviation from 1981-2010 of the global sea ice extent was -6.89σ on October 31, 2025, which is remarkable given the absence of El Niño conditions in 2025. 


Arctic sea ice volume

Meanwhile, Arctic sea ice volume remains at a record daily low, as it has been for more than a year. The image below shows Arctic sea ice volume through October 31, 2025.


High temperatures

Low sea ice and polar amplification of the temperature rise contribute to high air temperatures at both poles. The image below shows the September 2025 temperature anomaly compared to 1951-1980.

[ from earlier post ]
The low sea ice and the high temperatures are even more remarkable given the absence of El Niño conditions.

Little sunlight is yet reaching the South Pole at this time of year. While temperatures over Antarctica are still well below zero °C, they are rising fast. Antarctic temperature anomalies were high in September 2025 (see the above image) and in October 2025 (see the image below). 

The image on the right, adapted from NOAA, shows the ENSO outlook (CFSv2 ensemble mean, black dashed line) favors La Niña persisting into the early Northern Hemisphere winter 2025-26.

The image on the right, adapted from ECMWF, shows the ENSO anomaly and forecast for developments in Niño3.4 through August 2026, indicating that the next El Niño will emerge and grow in strength in the course of 2026.  

A record high daily Antarctic temperature was reached on October 26, 2025, corresponding with a temperature anomaly of +5.08°C versus 1979-2000, as illustrated by the image below. 

The inset on the image below shows high temperature anomalies at both poles vs 1991-2020 on October 26, 2025. 


A record high daily Arctic temperature was reached on October 27, 2025, corresponding with a temperature anomaly of +5.99°C versus 1979-2000, as illustrated by the image below. The inset on the image below shows high temperature anomalies at both poles vs 1991-2020 on October 27, 2025. 

Global temperature anomalies have been rising over the past few months, and reached a record daily high of 15.04°C, an anomaly of +0.93°C versus 1991-2020, on October 25, 2025, as illustrated by the image below.

The following day, on October 26, 2025, the temperature reached another daily high. The image below shows temperature anomalies in red from January 1, 2023, through October 26, 2025, with a non-linear (polynomial) trend added in blue. 


Note that the anomalies on the above images are calculated from 1991-2020. When calculated from pre-industrial, the anomalies will be much higher, as discussed in earlier post such as this one

The image below shows a forecast of the temperature anomaly vs 1981-2010 for November 2025. 


The image below shows a forecast of the temperature anomaly versus 1981-2010 for December 2025. 


The situation is dire. An Antarctic Blue Ocean Event (sea ice approaching a low of one million km²) threatens to occur in February 2026, triggering an Arctic Blue Ocean Event later in 2026 while the next El Niño is strengthening, which comes with a huge danger of massive amounts of methane erupting from the seafloor. 

Southern Ocean sea surface getting more salty

High temperature anomalies are present at both the poles, as illustrated by the image below that shows the situation on October 25, 2025. 


High temperatures come with Jet Stream distortion on October 25, 2025, as illustrated by the image below that shows the Jet Stream (at 500 hPa) moving deep over Antarctica. 


This came with high precipitable water anomalies over Antarctica, as illustrated by the image below. 


This came with snowfall over Antarctica, as illustrated by the image below. 


The danger has been discussed in earlier posts such as this one. The increased snowfall thickens the snow on Antarctica with only little freshwater returning to the ocean. As a result, the Southern Ocean surface is getting more salty, and as also discussed in an earlier post, saltier surface waters sink more readily, allowing heat from the deep to rise, which can melt Antarctic sea ice from below, even during winter, making it harder for ice to reform. This vertical circulation also draws up more salt from deeper layers, reinforcing the cycle.

This leads to a loss of sea ice (and thus loss of albedo and latent heat buffer), as well as less heat getting transferred from the atmosphere into the Southern ocean, while more heat can be transferred from the Southern Ocean to the atmosphere. 

The methane danger

The methane danger is illustrated by the image below, adapted from an image issued by NOAA October 29, 2025, showing hourly methane averages recorded at the Barrow Atmospheric Baseline Observatory (BRW), a NOAA facility located near Utqiaġvik (formerly Barrow), Alaska, at 71.32 degrees North. 


Danger assessment

A state of emergency is typically declared after a disaster hits a specific area. The idea is that repairs or replacement of buildings, equipment and infrastructure can quickly restore the situation to what it previously was. Insurance companies have traditionally determined premiums for insurance policies by calculating the risk of events by their severity and probability.   

However, extreme weather events can increasingly be expected to occur more frequently and important considerations are the intensity and severity at which one specific place gets hit by an event, as well as ubiquity and imminence of such events. As temperatures rise, more extreme weather events can be expected to occur with greater intensity, more frequently, over larger areas, with longer duration and to become more ubiquitous and follow each other up with increasing if not accelerating rapidity.


As the likeliness of a huge and accelerating temperature rise, the severity of its impact, and the ubiquity and the imminence with which it will strike all become more manifest—the more sobering it is to realize that a mere 3°C rise may suffice to cause human extinction.

Climate Emergency Declaration

UN secretary-general António Guterres recently spoke about the need for “a credible global response plan to get us on track” regarding the international goal of limiting the global temperature rise. “The science demands action, the law commands it,” Guterres said, in reference to a recent international court of justice ruling. “The economics compel it and people are calling for it.”

What could be added is that the situation is dire and unacceptably dangerous, and the precautionary principle necessitates rapid, comprehensive and effective action to reduce the damage and to improve the outlook, where needed in combination with a Climate Emergency Declaration, as described in posts such as this 2022 post and this one and as discussed in the Climate Plan group.

Antarctic sea ice in danger

The Antarctic sea ice area was 12.54 million km² on October 17, 2025, the second lowest daily area (behind 2023) and a deviation from 1981-2010 of -4.15σ.


This low Antarctic sea ice area is alarming. Antarctic sea ice typically reaches its annual low in February. The record low of 1.09 million km² that was reached on February 24, 2023, was very close to a Blue Ocean Event, yet the deviation then was only -2.86σ.

High temperature anomalies over Antarctica and high sea temperatures are behind the low sea ice area. The image below shows how much higher the September 2025 temperature was than it was in 1951-1980.

[ from earlier post ]
At this time of year, little sunlight is reaching the South Pole yet, so temperatures over Antarctica are still well below zero °C. Nevertheless, temperature anomalies were high in September 2025 and anomalies were as high as +4.22°C compared to 1979-2000 on October 14, 2025, which is remarkable given the absence of El Niño conditions. Record high daily temperatures were reached on each day of the period from 12 to 17 October 2025. The inset shows high polar temperature anomalies versus 1991-2020 on October 17, 2025.

[ click on images to enlarge ]
Meanwhile, Arctic sea ice volume remains at a record daily low, as it has been for more than a year, as illustrated by the image below. This contributes to low global sea ice, as this causes less sunlight to be reflected and instead more sunlight to be absorbed by the ocean surface. 


The global sea ice area was 3.45 million km² lower than 1981-2010 on October 17, 2025, a deviation from 1981-2010 of -4.47σ, as illustrated by the image below.


The image below shows Antarctic sea ice concentration on October 17, 2025.


The image below shows Antarctic sea ice thickness on October 17, 2025.


The situation is dire. An Antarctic Blue Ocean Event (sea ice approaching a low of one million km²) could occur in February 2026, triggering an Arctic Blue Ocean Event later in 2026.   

Climate Emergency Declaration

UN secretary-general António Guterres recently spoke about the need for “a credible global response plan to get us on track” regarding the international goal of limiting the global temperature rise. “The science demands action, the law commands it,” Guterres said, in reference to a recent international court of justice ruling. “The economics compel it and people are calling for it.”

Transform Society with the Climate Plan

[ image from this 2019 post, text discussed in earlier posts such as this 2022 one and links below ]

The Climate Plan calls for Transformation of Society in at least four sectors, as follows:

1. Energy - Generate clean, renewable energy with solar panels, turbines and batteries.

2. Food - Produce vegan-organic food and pursue synthetic food, solar food and precision fermentation.

3. Waste management - Pyrolyze organic waste with the biochar added to the soil.

4. Construction and Activities - Transition to online work, ordering, education and health diagnosis, using wood and green steel to construct buildings, vessels, bridges and water storage, while adding olivine sand to footpaths, bikeways, paths, gardens, beaches, forests and water bodies, and while letting eVTOL air taxis add extra mobility, battery exchange and mobile communications, in support of microgrids, WiFi, microwave and laser links.

The above transitions will help increase forests, as discussed in posts such as this one. Reforestation and afforestation efforts work best when including restoration of wildlife and creation of food forests as discussed in this post and in this post. A recent study led by Evan Fricke finds that with healthy populations of animals that disperse seeds, tropical forests can absorb up to four times more carbon. A 2024 study led by Maddi Artamendi finds a notable negative impact of reduced pollinator species diversity on plant reproductive success measures, such as seed set, fruit set and fruit weight. 

The images below illustrate the decline over time of wild mammals and birds, compared to humans, livestock and poultry.

Emissions and Temperature Rise

The image below shows the Planet by land biome, i.e. forests, grassland, desert, tundra and shrubland. Rainforests are common in equatorial areas and they have steady temperatures year-round and high precipitation allowing for evergreen and semi-evergreen trees. Boreal forests, also called Taiga, cover much of the planet’s northern latitudes and their trees are coniferous (non-shedding), while trees in temperate areas do shed their leaves (deciduous).


Forests come with many climate benefits. Trees take carbon out of the atmosphere and store the carbon in the trees and in the soil, thus reducing global warming. Less carbon dioxide in the atmosphere also reduces ocean acidification. The top layer (canopy) of rainforests contains giant trees that can grow to heights of 75 m (about 250 ft) or more. The canopy prevents much sunlight from reaching the ground, thus cooling the surface locally. Trees hold the soil together and can pump up water from deep in the soil and, through evaporation, keep the surface and soil cool, thus also avoiding erosion and reducing fire hazards.

So, trees are responsible for cooling in many ways. Trees can darken the surface, which can cause more sunlight to be absorbed, thus resulting in more warming, but trees can also cause cooling in another way. Trees also release terpines and other biogenic volatile organic compounds (BVOCs) into the air. These BVOCs can react chemically in the atmosphere to form aerosols that reflect incoming solar radiation and thereby cause global cooling. These aerosols can also act to start clouds to form that result in rainfall and that shade the surface, reflecting more solar radiation back into space and thus cause further global cooling. 

While BVOCs have many benefits, they can also indirectly increase potent greenhouse gases including ozone and methane by depleting hydroxyl. A study led by Gillian Thornhill found that this could cause half the cooling effects of BVOCs to be lost. A recent study led by James Weber found that, when all the effects are combined, they can reduce the net climate benefit of wide scale tree-planting by up to one third.



The above image shows that organic matter aerosol optical thickness (55 nm) as high as 0.93 τ was recorded over North Australia on October 14, 2025 06:00 UTC.

A recent study led by Hannah Carle finds that a transition from sink to source has occurred for the aboveground woody biomass of the Australian moist tropical forests. Forests need to be supported and not just for their capacity to sequester carbon. The net climate benefit of trees is huge and is underestimated. While trees can cause some warming, they also cause more cooling. Their BVOCs are responsible for some depletion of hydroxyl, but this should be no reason to withhold support for forests. Instead, climate action should strongly support forests, while greater hydroxyl abundance is best accomplished by cleaning up industry sectors such as agriculture, transport and electricity generation.

IPCC downplays the temperature rise

The IPCC downplays the temperature rise in efforts to hide some of the most effective and necessary action, e.g. by presenting the impact of land use, gases and aerosols in most peculiar ways. Instead of comparing the climate impact of forests versus agriculture in commonly comprehensible language, such as a rise in degrees Celsius, the IPCC uses technical terms to make things less comprehensible for the typical reader (and voter).

As an example, the IPCC seeks to present deforestation as a change in land use that results in greater cooling, e.g. by arguing that deserts reflect more light back into space. As another example, the IPCC makes it look as if the temperature started rising only from 1850-1900, in efforts to hide the huge impact of deforestation that took place before those years.

Of the 14.9 billion hectares of land on the planet, only 71% of it is habitable – the other 29% is either covered by ice and glaciers, or is barren land such as deserts, salt flats, or dunes. About 10,000 years ago, 57% of habitable land was covered by forest and 42% was covered by wild grassland and shrubs. In 2023, 45% of habitable land was used for agriculture, as illustrated by the image below.


People have been herding animals and burning or cutting down trees for thousands of years. Before the Industrial Revolution, wood and plants were used for shelter and as building material. Plants also provided food for people and fodder for animals that were herded and that were used for food, ploughing, hunting, herding and transport. Biomass was also burned for heating, preparing food, cooking water, lighting and protection. 

Deforestation was the result of people's growing demand for biomass. Deforestation also increased due to trees getting cut down or burned as demand grew for land that could be used for urban purposes, as pasture or to grow more food and fodder.

[ click on images to enlarge ]

The 1850-1900 period that the IPCC uses as base to measure the temperature rise doesn't reflect pre-industrial well, for a number of reasons. Firstly, people's emissions pushed up temperatures long before that. Secondly, the 1850-1900 period was dominated by burning coal to provide heating and energy, which came with sulphur co-emission causing surface cooling, masking the temperature rise.

The rise from 1750 to 2024 in methane, carbon dioxide and nitrous oxide is illustrated by the image on the right, based on IPCC and WMO data.

While emission by people did accelerate since the start of the Industrial Revolution and even more recently, the rise in emission by people had already started thousands of years ago with growth in agriculture, herding of animals and associated deforestation, as illustrated by the combination image below, based on Ruddiman et al. (2015).

[ from earlier post ]
The temperature has risen accordingly since those times. Deforestation and growth in irrigation and numbers of people, livestock and herded animals and their crop waste, sewage and manure resulted in emissions. While much of the forests could initially regrow, the net result was a gradual loss of trees and the cooling aerosols they previously provided and a gradual growth in emissions such as methane, carbon dioxide, carbon monoxide and black carbon (soot). 

A 2013 study by Bond et al. calculates that black carbon has a warming effect of about 1.1 W/m², part of which is caused by black carbon darkening the snow and ice cover since pre-industrial times, as discussed on the aerosols page. By some calculations, the temperature in 1520 had risen by 0.29°C, compared to thousands of years earlier.

September 2025 temperature anomaly

The image below shows how much higher the September 2025 temperature was than it was in 1951-1980. 


The above image shows that the September 2025 temperature anomaly was high over both poles and especially high over some areas in Antarctica, where anomalies higher than +10°C versus 1951-1980 were recorded. 

As the image below shows, the temperatures recorded over Antarctica throughout September 2025 were higher than in most earlier years, while a record daily high temperature was recorded on October 10, 2025, a +3.62°C anomaly compared to 1979-2000. The inset shows high temperature anomalies versus 1991-2020 at both poles on October 10, 2025.


The image below shows that the global September 2025 temperature anomaly was 1.306°C higher than 1951-1980. Note that the 2025 anomalies were reached under borderline La Niña conditions that suppress temperatures and that the monthly temperature anomaly would be significantly higher when calculated from 1850-1900, which is typically used by the IPCC as baseline. 

[ Temperature Rise, click on images to enlarge ]
The full historic temperature rise and the rise to come soon could be much higher, as described on the image and below. The inset is also displayed and discussed in more detail below. 

Emissions and Temperature Rise

The observed temperature rise (O) is actually masked by aerosols (M) and the IPCC only includes the rise from the period 1850-1900, ignoring the rise before the period 1850-1900 (P) and the rise that took place to negate the natural fall in temperature. Aerosols could fall out of the air soon, so when adding things up (E1+E2), the historic temperature rise from pre-industrial (O+M+P) is huge. 

When also taking into account that the temperature would have fallen naturally (i.e. in the absence of these emissions and in line with Milankovitch cycles, the rise caused by people to negate that could also be included (E3), adding up to an even higher historic temperature rise (O+M+P+H).


Additionally, the full impact of all past emissions may not be fully felt yet, e.g. the full effect of carbon dioxide emissions reaches its peak only a decade after emission (E4). Furthermore, humans are likely to continue to cause emissions in the near future (E5). Finally, additional releases of greenhouse gases are likely to come from what was once called permafrost and from sinks turning into sources, resulting in an additional rise that's already baked into the cake (E6). Therefore, the historic rise plus the rise to come soon (O+M+P+H+F) may approach 5°C.

The diagram below further illustrates the importance of feedbacks and deforestation. Removal of trees has caused deforestation and soil carbon loss since prehistoric times, in turn causing emissions including carbon dioxide, methane and black carbon, while also reducing cooling aerosols released by trees and while also reducing the heat buffer of evaporation that previously cooled the atmosphere. Since prehistoric times, burning wood and deforestation has caused emissions of black carbon and dust that blackened the snow and ice cover, thus speeding up its decline. 

[ from earlier post ]

The image below illustrates how much the temperature may have risen from pre-industrial times and how much potential there is for a 3°C rise as early as in 2026.

Climate Emergency Declaration

UN secretary-general António Guterres recently spoke about the need for “a credible global response plan to get us on track” regarding the international goal of limiting the global temperature rise. “The science demands action, the law commands it,” Guterres said, in reference to a recent international court of justice ruling. “The economics compel it and people are calling for it.”

What could be added is that the situation is dire and unacceptably dangerous, and the precautionary principle necessitates rapid, comprehensive and effective action to reduce the damage and to improve the outlook, where needed in combination with a Climate Emergency Declaration, as described in posts such as this 2022 post and this one and as discussed in the Climate Plan group.
