Emissions are not falling

Temperature rise

For many years, alarms have been raised about the temperature rise. Forest fires and methane releases in the Arctic contribute strongly to the temperature rise and to the danger of the clouds tipping point getting crossed, as discussed in an earlier post. 

On July 21, 2026, the world (60°S–60°N, 0–360°E) sea surface temperature was 21.11°C, a record high temperature for the time of year and 0.92°C higher than 1982-2010, the highest anomaly versus 1982-2010 on record. The globe (inset top right) shows sea surface temperature anomalies versus 1991-2020 on July 21, 2026.

Ocean heat constitutes the primary cause of sea ice decline, as discussed in earlier post such as this one. In a publication issued July 13, 2026, NOAA announced El Niño to be present, adding that the 2026 El Niño will strengthen through the end of the year. The 2026 El Niño thus threatens to contribute to loss of virtually all Arctic sea ice in September 2026, as well as loss of virtually all Antarctic sea ice in early 2027, as also illustrated by the sea surface temperature anomaly forecast below for January 2027, a time of very rapid melting of Antarctic sea ice.

Clearly, politicians must take drastic action that includes action to increase resilience and action to reduce emissions caused by people. Yet, is effective action being taken? Sadly, it appears that politicians are not taking the necessary action and that - as a result - emissions are rising.

Greenhouse gases rising

Greenhouse gas concentrations have been rising since 1750, as illustrated by the image on the right. Carbon dioxide and nitrous oxide have been rising rapidly, while methane has been rising even more rapidly. 

More methane threatens to erupt from the seafloor, as discussed in earlier posts such as this one and this one. 

The 2026 El Niño is strengthening and sea surface temperatures are already at a record high for the time of year, as illustrated by the image below.

Ocean heat threatens to destabilize sediments at the seafloor of the Arctic Ocean, causing massive eruptions of methane contained in those sediments in the form of methane hydrates and free gas held underneath these hydrates. 

Concentrations of gases

The image below, dated July 21, 2026, shows carbon dioxide concentrations at Mauna Loa, Hawaii. While concentrations should be coming down at this time of year due to seasonal changes, recent concentrations are very high, with one recent flask reading exceeding 442 parts per million.

The image below, dated July 21, 2026, shows carbon monoxide concentrations at Mauna Loa, Hawaii. There is a huge spread in recent readings, which may reflect forest fires. 

The image below, dated July 21, 2026, shows hourly average methane concentrations at Utqiaġvik, formerly known as Barrow, Alaska. 

The image below, dated July 21, 2026, shows hourly average nitrous oxide concentrations at Utqiaġvik, formerly known as Barrow, Alaska. 

Sadly, the images indicate that concentrations of greenhouse gases are not falling, they are rising instead. Forest fires are striking across the globe, which contributes to forests turning from carbon sinks into carbon sources, as discussed in posts such as this one. Furthermore, forest fires come with huge releases of carbon monoxide that deplete hydroxyl, in turn extending the lifetime of methane, as discussed in an earlier post. 

Fossil fuel subsidies and investments 

Meanwhile, fossil fuel companies are planning to extract more natural gas. The IEA estimates that around $1.2 trillion is set to be invested in oil, natural gas and coal in 2026. Natural gas investment is projected to rise to $330 billion, the highest level in a decade.

The IMF describes two different types of fossil fuel subsidies. Explicit subsidies (when the retail price is below a fuel’s supply cost) and implicit subsidies (when the retail price fails to include external costs, inclusive of the standard consumption tax). External costs include contributions to climate change through greenhouse gas emissions, local health damages (primarily premature deaths) through the release of harmful local pollutants like fine particulates, and traffic congestion, accident, and road damage externalities associated with the use of road fuels.

Conclusion

The situation is dire and unacceptably dangerous, and the precautionary principle necessitates the danger to be acknowledged, while facilitating 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 in this 2022 post and this 2025 post, and as discussed in the Climate Plan group.

Extreme weather events

Temperatures in the United States

As illustrated by the above image, adapted from a NOAA forecast, a massive winter storm is forecast to hit much of the U.S. (forecast valid through January 26, 2026).

The above image, adapted from ClimateReanalyzer, shows that temperature anomalies as low as -45°F (-25°C) are forecast to hit Texas on January 24, 2026. 

The above image, adapted from ClimateReanalyzer, shows that temperatures as low as 9°F (-12.78°C) are forecast to hit Texas on January 24, 2026.

The above image, adapted from nullschool.net, shows temperatures as low as -0.8°F (-18.12°C) forecast to hit Kansas on January 24, 20026 (at the green circle).

Temperatures in Russia

The image below shows that, on January 26, 2026, temperatures in Russia were as low as -52°F (-46.6°C) at a location in Russia at 63.5°N (green circle). This is well outside of the Arctic Circle, which is at 66°3'N. Within the Arctic Circle, sunlight is absent on the winter solstice. 

As temperatures keep rising, many feedbacks are striking with increasing vigor, resulting in higher temperature anomalies at the Arctic (polar amplification), resulting in more cold air descending deeper outside of the Arctic Circle (Jet Stream distortion), and resulting in more massive snowfall (7% more water in the air for each 1°C rise in temperature). 

Jet Stream distortion and further feedbacks

For some, the cold weather forecasts may raise questions as to how this can happen, given the overwhelming scientific evidence that global temperatures are rising as a result of activities by people.

The image below may be helpful when responding to such questions. The image shows Wind + Instantaneous Wind Power Density at 250 hPa, at an altitude where the Jet Stream is strong. The image illustrates that, because temperatures over continents are low in the Northern Hemisphere at this time of year while sea surface temperature are high due to global warming, there is a strong difference between temperatures over land and temperatures over the ocean. This strong temperature difference strengthens the speed of latitudinal winds, i.e. the prevailing wind patterns that are moving east-west across Earth, driven by solar heating differences and the Coriolis effect.

[ click on images to enlarge ]

The above image shows a wind speed of 377 km/h and a Wind Power Density of 206.8 kW/m² at 250 hPa at the green circle off the coast of Japan. Furthermore, polar amplification narrows the temperature difference between the Equator and the poles, which distorts the path of the Jet Stream, resulting in circular wind patterns at higher altitudes North. 

The Jet Stream used to keep cold air in the Arctic, separated from warmer air at lower latitudes. A distorted Jet Stream causes the Arctic to heat up strongly, while lower latitudes get colder, as illustrated by the image below, showing the temperature anomaly on January 24, 2026, 18z. This has been coined the 'open doors' feedback, it's like the door of the freezer is left open. 

The combination image below shows images adapted from Copernicus. The image on the left shows temperature anomalies at the bottom end of the scale over parts of North America and Russia on January 24, 2026, while temperature anomalies are at the top end of the scale over much of the Arctic. The image on the right shows absolute temperatures on January 24, 2025, further illustrating to what extent cold air has descended from the Arctic over the continents.

The image below shows the temperature anomaly (left) and the minimum temperature (right) on January 25, 2026, with images adapted from ClimateReanalyzer. 

The combination image below further illustrates the situation on January 26, 2026. Jet Stream distortion occurs due to a narrowing of the temperature difference between the Equator and the poles, and due to a stronger temperature difference between oceans and continents. This can cause the Jet Stream to form Omega patterns and even go circular. Further feedbacks that can amplify the situation include more water vapor in the air, which can come with strong precipitation. 

[ click on images to enlarge ]

The image on the left shows wind and surface temperatures; very low temperatures show up over land (Russia, Canada, Greenland), much lower than temperatures over the Arctic Ocean. The image at the center shows wind and sea surface temperature anomalies (SSTA). High SSTA show up off the east coast of Asia and off the east coast of North America. The image on the right shows wind patterns at 250 hPa, which corresponds with a Jet Stream altitude of approximately 10,500 m. A location (48°N,57°W) is highlighted by the green circle on each of the images, on at the image on the right the wind there reaches a speed of 399 km/h (or 248 mph). 

The image below shows the 2025 temperature anomaly versus 1951-1980 (NCEP/NCAR Reanalysis v1). The highest anomalies show up at the poles, reflecting polar amplification of the temperature rise, caused by decline of the snow and ice cover and by further feedbacks.

[ from earlier post ]

The global temperature rise comes with many feedbacks, including more water vapor in the atmosphere, polar amplification of the temperature rise and distortion of the Jet Stream, which can at times result in unusually low temperatures over continents in the Northern Hemisphere.

Importantly, distortion of the Jet Stream can at times also result in large amounts of ocean heat getting carried into the Arctic Ocean, abruptly heating up the water of the Arctic Ocean and threatening to destabilize methane hydrates contained in sediments at the seafloor, resulting in huge methane eruptions.

Climate Emergency Declaration

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 in this 2022 post and this 2025 post, and as discussed in the Climate Plan group.

Should people be told?

The image below, made with a screenshot from Berkeley Earth, shows an annual average temperature rise of 3°C or more in 2050 in China for each of the three scenarios looked at.

China is important, it has a large well-educated population and a large part of global emissions is released in China. Some countries face even more dire prospects. Have people been told how dire the situation is? The general lack of climate action around the world suggests that people have not been sufficiently informed. Moreover, many scientists, journalists, judges, politicians and civil servants bluntly refuse to inform people.

[ from earlier post ]

[ Top: Extreme risk impact, adapted from Planetary Solvency actuaries.org.uk (2025). 
Bottom: 5.163°C rise, climatereanalyzer.org image, from earlier post ]

The image below shows the January 2025 temperature anomaly, compared to NASA's default 1951-1980 base. 

The image below shows that monthly temperature anomalies have been more than 1.5°C above 1903-1924 (custom base, not pre-industrial) for 19 consecutive months (July 2023 through January 2025). The anomaly is rising rapidly, the red line (2-year Lowess Smoothing trend) points at a 2°C rise in 2026 (compared to 1903-1924, which - as said - is not pre-industrial).

Warnings about the potential for a huge rise in temperature have been sounded before, e.g. see the extinction page and the image below with daily data and added trends.

While La Niña conditions are definitely present in January 2025, the La Niña is expected to be short-lived. Temperatures are typically suppressed during La Niña. Despite temperatures being suppressed, the global surface air temperature reached 13.33°C on February 11, 2025, or 0.67°C above 1991-2020, according to ERA5 data. Temperatures keep rising, as indicated by the trends added to and based on the data, despite La Niña.

Will a new El Niño emerge in the course of 2025?

La Niña conditions are currently present. The probabilities of El Niño conditions are expected to rise in the course of 2025. Moving from the bottom of a La Niña to the peak of a strong El Niño could make a difference of more than 0.5°C, as illustrated by the image below.

[ Temperature rise due to El Niño from earlier post ]

The image below, adapted from NOAA, shows monthly temperature anomalies colored by ENSO values.

[ temperature anomaly through January 2025 colored by ENSO values, click to enlarge ]

Despite the presence of La Niña, temperatures keep rising. Will a new El Niño emerge in the course of 2025? The image below shows a NOAA forecast dated February 13, 2025. 

The potential for a huge temperature rise within a few months time

Earth's temperature imbalance is growing, as emissions and temperatures keep rising. In a cataclysmic alignment, the upcoming El Niño threatens to develop while sunspots are higher than expected. Sunspots are predicted to peak in July 2025. The temperature difference between maximum versus minimum sunspots could be as much as 0.25°C.

There are further mechanisms that could accelerate the temperature rise, such as reductions in aerosols that are currently masking global warming. Furthermore, the temperature rise comes with numerous feedbacks such as loss of sea ice, loss of lower clouds, more water vapor in the atmosphere and changes in wind patterns and ocean currents that could cause extreme weather events such as forest fires and flooding to increase in frequency, intensity, duration and area covered, and oceans to take up less heat, with more heat instead remaining in the atmosphere. The self-reinforcing nature of many of these feedbacks could cause the temperature rise to accelerate strongly and rapidly within a few months time.

According to an earlier analysis, the 2°C above pre-industrial threshold may already have been crossed and we're moving toward 3°C at a pace that is accelerating, rather than slowing down. Once more, isn't it high time for people to be told how dire the situation is?

Double Blue Ocean Event 2025?

[ from earlier post ]

The above image, from Berkeley Earth, illustrates the importance of Antarctic Sea ice loss in accelerating the temperature rise.

Antarctic sea ice is moving toward 1 million km² in area, a threshold when a Blue Ocean Event could be declared in the Southern Hemisphere, as illustrated by the image below.

Researchers on board the ship Sarmiento de Gamboa recently observed columns of methane in the ocean up to 700 meters long and 70 meters wide. Researchers looked for leaks on the edges of Antarctica, according to a recent news report. “We have estimated that in this area there are some 24 gigatons of carbon accumulated in methane hydrates”, warns Roger Urgeles, of the Institute of Marine Sciences, based in Barcelona, leaders of the expedition.

An Antarctic Blue Ocean Event alone would dramatically increase Earth's Heat Imbalance. The combination of low sea ice area around Antarctica and in the Arctic looks set to cause a dramatic temperature rise over the coming months. 

[ Arctic sea ice volume, click to enlarge ]

Persistently low global sea ice area therefore also threatens a Blue Ocean Event to occur in the Arctic later this year. 

Ominously, Arctic sea ice volume is at a record low for the time of year, as illustrated by the image on the right, showing Arctic sea ice volume on February 15, 2025. 

An Arctic Blue Ocean Event threatens to destabilize hydrates contained in sediments at the seafloor of the Arctic Ocean, causing eruptions of huge amounts of methane, with the resulting temperature rise in the Arctic causing permafrost on land to thaw strongly and abruptly, in turn causing additional greenhouse gas releases. 

The above image shows methane as high as 2561 ppb at 399.1 mb recorded by the N21 satellite on February 5, 2025 am. 

[ for more background, also view the Extinction page ]

The stacked bar chart on the right includes (at the bottom) a potential 2.29°C for the rise in temperature from pre-industrial to 2020. 

A rise of 0.5°C is included for the additional CO₂ released through 2026 and for the rising impact of the recently emitted CO₂. Note that the chart was first conceived in 2016, so the impact of the CO₂ released from 2016 to today has meanwhile already eventuated. 

Changes in aerosols are given the potential for a 1.9°C rise due to reductions in cooling aerosols (mainly sulfate), while a 0.6°C rise is included due to additional warming gases and aerosols. 

In the bar chart, a potential rise of 1.6°C is reached by the end of 2026 as a result of snow and ice loss and changes in wind patterns and ocean currents. 

An additional 1.1°C is reached as a result of eruption of methane from the seafloor, while additional greenhouse gas emissions result in a 0.35°C rise. 

The temperature rise itself triggers further feedbacks such as an increase of water vapor in the atmosphere (2.1°C) and loss of lower clouds (8°C). Altogether, the rise could reach 18.44°C by the end of 2026. Warnings about the potential for such a rise have been sounded before, e.g. at the extinction page. Note the above-mentioned warning that humans will likely go extinct with a 3°C rise. 

Climate Emergency Declaration

The situation is dire and the precautionary principle calls for rapid, comprehensive and effective action to reduce the damage and to improve the situation, as described in this 2022 post, where needed in combination with a Climate Emergency Declaration, as discussed at this group.

Global temperature rise

The image below illustrates the threat that the temperature rise may exceed 3°C. The blue trend, based on January 1880 to March 2023 data, shows how 3°C could be crossed in 2036. The magenta trend, based on January 2010 to March 2023 data, better reflects relatively short-term variables such as El Niño and illustrates how 3°C could be crossed as early as in 2025.

The above image uses monthly NASA Land+Ocean temperature anomalies versus 1886-1915 that are further adjusted by 0.99°C to reflect ocean air temperatures, higher polar anomalies and a pre-industral base, as also illustrated by the image below. 

What could cause the temperature rise to cross 3°C in 2025? This has been discussed in earlier posts such as this one. Briefly, such a rise could be triggered by relatively short-term variables such as the upcoming El Niño, high sunspots and extra water vapor in the atmosphere due to the eruption of a submarine volcano. Together, they could raise temperatures by more than half a degree Celsius, triggering the compound impact of further events including feedbacks kicking in with greater ferocity and tipping points getting crossed, such as the latent heat tipping point and the seafloor methane tipping point.

Indeed, rising temperatures threaten to cause massive loss of sea ice followed by eruptions of methane from the seafloor of the Arctic Ocean. This threat is further illustrated by the image below. 

Sea surface temperature

On April 29, 2023, the sea surface off the coast of South America was as much as 6.1°C or 10.9°F hotter than it was in 1981-2011, as illustrated by the image below that also shows a distorted Jet Stream that is stretched out from pole to pole (wind at 250 hPa).

Sea Surface Temperature World (60S-60N)

On April 28, 2023, the world sea surface temperature (SST between 60°South and 60°North) had been at 21°C or higher for as many as 38 days. Such temperatures are unprecedented in the NOAA record that goes back to 1981.

Recently (e.g. on April 4, 2023), the sea surface temperature in 2023 (black line) was as much as 0.3°C higher than in 2022 (orange line) on April 28, 2023, and this while we're only just entering the upcoming El Niño.

Sea Surface Temperature North Atlantic

The situation is especially critical in the North Atlantic. Last year (in 2022), North Atlantic sea surface temperatures reached a record high of 24.9°C in early September. Recently (e.g. on April 4, 2023), the North Atlantic sea surface temperature was as much as 0.5°C higher (black line) than in 2022 (orange line).

On April 28, 2023, the sea surface temperature in the North Atlantic was 20.6°C, the highest temperature for the time of year in the NOAA record that goes back to 1981. 

As we're moving into the upcoming El Niño, the Arctic Ocean can be expected to receive more and more heat over the next few years, i.e. more heat from direct sunlight, more heat from rivers, more heat from heatwaves and more ocean heat from the Atlantic Ocean and the Pacific Ocean.

Monthly Northern Hemisphere Land Temperature Anomaly

Temperatures have been rising especially fast on land in the Northern Hemisphere, where most people are living. As temperatures keep rising, more extreme weather events can be expected that can make life hard, if not impossible, even at higher latitudes.

The image below shows monthly anomalies up to March 2023, with two trends added. The blue trend, based on January 1850-March 2023 NOAA data, points at a 3°C rise in 2032. The magenta trend, based on October 2010-March 2023 NOAA data, better reflects variables such as El Niño and sunspots, and illustrates how they could trigger a rise of more than 3°C in 2024 and a rise of more than 5°C in 2026. Note that the image displays anomalies versus 1901-2000, anomalies versus pre-industrial would be significantly higher.

  

[ from earlier post ]

Greenhouse gas levels

Carbon dioxide (CO₂) broke three records recently, for the daily, weekly and monthly average. The daily CO₂ average was 425.01 ppm on April 28, 2023, the weekly CO₂ average was 424.4 ppm for the week beginning on April 23, 2023, and the monthly CO₂ average was 423.38 ppm in April 2023, each of them the highest carbon dioxide levels on record at Mauna Loa, Hawaii, as illustrated by the image below.

CO₂ typically reaches its annual high in May or June, so these records can be expected to be broken over the next few months.

[ from earlier post ]

Even more crucially, methane emissions should be cut rapidly and dramatically, as discussed in an earlier post. If a trend such as the one in the above image continues, the Clouds Tipping Point could be crossed as early as in 2027 due to forcing caused by the rise in methane alone, while  this could happen even earlier than in 2027 when further forcing other than just the forcing from methane is taken into account. Crossing the Clouds Tipping Point, at 1200 ppm CO₂e, could on its own cause a further rise of 8°C. 

NOAA's 1924.99 ppb for the December 2022 global methane mean translates into 385 ppm CO₂e when using a 1-year GWP of 200 for methane.

So, adding this 385 ppm CO₂e to 425 ppm CO₂ would leave just 390 ppm CO₂e for further forcing, before the Clouds Tipping Point would get crossed, as the image on the right illustrates.

Methane at higher altitude can reach even higher levels than NOAA's global marine surface data. As illustrated by an image in an earlier post, monthly methane recently rose to above 1950 ppb at Mauna Loa, Hawaii.

Further changes such as caused by sea ice loss and changes in aerosols can also speed up the temperature rise.

El Niño and further variables

We're moving into an El Niño, as illustrated by the image on the right, adapted from NOAA.

Moving from the bottom of a La Niña to the peak of a strong El Niño could make a difference of more than half a degree Celsius, as discussed in an earlier post. El Niño can be expected to reach its full strength within a few years, with a maximum possible in 2026.

Furthermore, sunspots look set to reach a very high maximum within years, while the 2022 Tonga submarine volcano eruption did add a huge amount of water vapor to the atmosphere, as discussed in an earlier post.

In the video below, Guy McPherson gives his views.

Extinction

Vast amounts of ocean heat are moving toward the Arctic, especially in the North Atlantic, threatening to cause rapid melting of Arctic sea ice and thawing of permafrost.

The image on the right, adapted from NOAA, shows ocean heat moving toward the Arctic along the path of the Gulf Stream. 

Rising temperatures of the water in the Arctic Ocean threaten to trigger massive loss of sea ice (and loss of albedo) and eruptions of methane from the seafloor of the Arctic Ocean, as has been described many times before, such as in this post, in this post and in this post.

[ from earlier post ]

The above image illustrates the danger of two tipping points getting crossed, i.e. the Latent Heat Tipping Point and the Seafloor Methane Tipping Point.

Latent heat loss, feedback #14 on the Feedbacks page

[ see analysis at the Extinction page ]

Destabilization of methane hydrates at the seafloor of the Arctic Ocean threatens to result in explosive eruptions of methane, as its volume increases 160 to 180-fold when leaving the hydrates, as illustrated by the above image.

Conclusion

A huge temperature rise thus threatens to unfold over the next few years, as illustrated by the image on the right. The annual rise from pre-industrial to 2026 could be more than 18.44°C by 2026, and monthly anomalies could reach even higher.

Meanwhile, humans are likely to go extinct with a rise of 3°C and most life on Earth will disappear with a 5°C rise, as illustrated by the image below, from an analysis discussed in an earlier post.

This dire situation calls for urgent action as described in the Climate Plan. Reducing emissions alone won't be enough. Carbon also needs to be removed from the atmosphere and oceans, through re-/afforestation, through pyrolysis of biowaste with the resulting biochar (and nutrients) returned to the soil and further methods. Even with a rapid transition to clean, renewable energy, with changes to food, land use, construction and waste management, and with removal of large amounts of carbon from the atmosphere and oceans, still more action is needed.

Marine Cloud Brightening is a good idea, while many further methods may first need more surplus clean energy to be available and/or require more R&D.

Whether action will happen successfully and rapidly enough is indeed a good question, but that question shouldn't be used as an excuse to delay such action, since taking such action simply is the right thing to do.
