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 ]

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.

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.

Will we be alive in 2025, who will survive, 2025?


The above image, created with monthly mean global temperature anomalies by LOTI Land+Ocean NASA/GISS/GISTEMP v4 data while using a 1903-1924 base, has a trend added based on Jan 2016-Aug 2024 data. The image also shows that anomalies could be 0.99°C higher when using a more genuine pre-industrial base.

The image below featured in an earlier post and was created with an image from the NASA website while using an 1885-1915 base, illustrating the calculation behind this 0.99°C. More details are here.


The image below from Copernicus illustrates that, for more than 14 consecutive months, the temperature anomaly has been high, i.e. about 0.8°C (± 0.3°C) above the 1991-2020 average and much more when compared to a pre-industrial base, with little or no sign of a return to earlier temperatures.


The image below, from an earlier post and created with an image from the NASA website while using a 1903-1924 base, confirms that the monthly temperature anomaly through August 2024 has been more than 1.5°C above this base for each of the past consecutive 14 months. The post adds that anomalies will be even higher when compared to a pre-industrial base. The red line shows a trend produced by the NASA website (2-year Lowess Smoothing).


Potential causes for such a rapid temperature rise include a cataclysmic alignment of the temperature peak of the next El Niño coinciding with a peak in sunspots expected to occur in July 2025.

The black dashed line in the image below, adapted from NOAA, indicates a transition to La Niña in October 2024, persisting through Jan-Mar 2025.


The image below, adapted from NOAA, illustrates that El Niño conditions were present from June 2023 through April 2024, and that ENSO-neutral started in May 2024.


While El Niños typically occur every 3 to 5 years, as NOAA explains, El Niños can occur as frequently as every two years, as happened in 2002, 2004 and 2006, as the above image shows. 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.

The danger is that we could move into a new El Niño in 2025, while temperatures remain high due to feedbacks and while sunspots move toward a peak in this cycle, expected to occur in July 2025.

The image below (top part), adapted from NOAA, shows the observed values for the number of sunspots for cycle 25, through August 2024, as well as the values predicted by NOAA (red line).

[ from earlier post, click on images to enlarge ]

The above image (bottom part) shows the observed values for the F10.7cm radio flux for cycle 25, through August 2024, as well as the values predicted by NOAA (red line).

The observed values are much higher than predicted. If this trend continues, the rise in sunspots forcing from early 2020 to July 2025 may well make a difference of more than 0.25°C.

This - in combination with further events, developments and short-term variables - could constitute a cataclysmic alignment that could result in runaway temperature rise by 2026, as an earlier post concluded.

Natural variability is mentioned by the IPCC, but because such events vary from year to year, their impact is smoothed out in climate change calculations that average the temperature rise over the course of decades. Yet, when such events coincide in a cataclysmic alignment, as could be the case within the next few years, the extra rise in temperature from - say - the year 2021 could be over 0.75°C. Note that this is an extra rise, on top of the long-term rise due to activities by people since pre-industrial.

Furthermore, as emissions and temperatures keep rising, such an extra rise could trigger feedbacks that threaten to grow in strength and strike with ever greater ferocity, further accelerating the temperature rise while extreme weather disasters hit numerous regions around the world more frequently over larger areas, with greater intensity and for longer periods.


Such feedbacks include loss of sea ice and permafrost degradation, both terrestrial and on the seafloor of the Arctic Ocean, which looks set to cause huge releases of greenhouse gases. Temperature anomalies are high and Arctic sea ice volume is very low, as illustrated by the compilation of images below, adapted from nullschool, Climate Reanalyzer and the Danish Meteorological Institute.  


Ominously, high methane concentrations (well over 2400 ppb) were recently recorded at the observatory in Utqiagvik (Barrow), Alaska, as illustrated by the image below, adapted from NOAA


Slowing down of ocean currents could cause less heat to move deep into the ocean and more heat to instead accumulate at the surface, while more water vapor would enter the atmosphere, further speeding up the temperature rise, as discussed in earlier posts such as this one and as illustrated by the image below, created with NOAA data.
[ surface precipitable water through August 2024 ]
The compilation image below, with forecasts for September 20, 2024 03 UTC (run 00 UTC) adapted from Copernicus, illustrates gases and biomass-burning aerosols released due to forest fires burning in the Amazon. Formaldehyde and carbon monoxide cause hydroxyl depletion and thus extend methane's lifetime. 


Conflict and socio-economic stress could add further forcing. Heatwaves, fires, famine, drought, floods, crop loss, loss of habitable land and corrupt politicians threaten to cause violent conflicts to erupt around the world, industrial activity to grind to a halt and the temperature to rise above 3°C from pre-industrial, driving humans into extinction. Sadly, politicians and mainstream media fail to inform people about the danger, and once the full horror reveals itself, panic could be added to the problems the world faces.

Dangers associated with high temperatures are discussed in this earlier post. A 2018 study (by Strona & Bradshaw) indicates that most life on Earth will disappear with a 5°C rise. Humans, who depend for their survival on many other species, will likely go extinct with a 3°C rise, as illustrated by the image below, from an earlier post.

Very high temperatures in Tropics

Temperatures in the Tropics (23.5°S-23.5°N, 0-360°E) have been very high in 2024 (see black line, image below), much higher than they were at this time of year in 2023 (orange line). 


The above image shows that on May 24, 2024, the temperature was 26.7°C (or 80.06°F), an anomaly of 1°C (or 1.8°F) compared to 1979-2000. 

The image below shows the average monthly temperature anomaly over the past few years through April 2024, when the anomaly was 1.327°C (or 2.389°F) compared to 1951-1980.  


Note that the above-mentioned anomalies are compared to 1979-2000 and 1951-1980, neither of which is pre-industrial. The anomalies would be much higher when calculated from a pre-industrial base. 

The maps below are adapted from Climate Reanalyzer and show maximum temperatures for three days. The image directly below shows maximum temperatures on May 29, 2024. Extremely high temperatures were recorded in India and Pakistan.


The image below has a focus on Asia, showing the extremely high temperatures recorded in India and Pakistan on May 30, 2024. 


The image below shows maximum temperatures around the world on May 31, 2024. 


Surface precipitable water

Surface precipitable water reached a record high of 27.139 kg/m² in July 2023. Worryingly, data for the first four months of 2024 are a lot higher than they were in 2023 at the same time of year, as illustrated by the image below, adapted from NOAA. This raises fears that surface precipitable water will reach an even higher peak in 2024 than was reached in 2023. 


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.

Temperatures in the Tropics

The image below shows that temperatures in the Tropics (23.5°S-23.5°N, 0-360°E) were very high during the second half of April 2024, and these very high temperatures were sustained during the first part of May 2024. The temperature was 26.9°C (or 80.42°F) on May 11, 2024, an anomaly of 1.1°C (or 1.98°F) from 1979-2000. 


The image below shows the average monthly temperature anomaly over the past few years through April 2024, when the anomaly was 1.327°C (or 2.389°F) from 1951-1980.  


The image below, adapted from Climate Reanalyzer, shows maximum temperatures on May 28, 2024.


Calculating the temperature rise

Note that the anomalies for the top image are calculated from 1979-2000 as a base, while anomalies for the above image are calculated from 1951-1980 as a base. When calculated from a pre-industrial base, these anomalies will be much higher.

Also have a look at the analysis of sponges collected in the Caribbean, illustrated by the image on the right, from an earlier post.

Furthermore, a recent analysis shows that land temperatures 30°N- 90°N in summer 2023 were 2.07°C warmer than 1850-1900, while a subsequent longer-range analysis shows that the mean temperature in the period 1850 to 1900 was actually 0.24°C lower than had been presumed on the basis of the data collected at the time by meteorological stations.

A larger temperature rise comes with stronger feedbacks, e.g. the February 2024 temperature could be as much as 2.75°C above pre-industrial, corresponding with almost ⅕ more water vapor in the air. This is just one out of numerous feedbacks, while there are also developments such as reductions of sulfur emissions that can push up the temperature rise, as discussed in many earlier posts such as this one.

A larger temperature rise comes with increasingly extreme weather events that cause widespread damage and threaten to cause even more loss of life of people, livestock and wildlife, crop failures and ecosystem collapse in the tropics and elsewhere.

Strong hurricanes can significantly add to the danger. More hurricanes are forecast for the 2024 Atlantic hurricane season than during 1950-2020, as illustrated by the above image, from an earlier post.

The IPCC keeps downplaying how dire the situation is we're in

Meanwhile, the IPCC keeps giving the impression that the temperature rise is small, e.g. by using the period 1850-1900 as "reference", despite mounting evidence that the temperature rise is much larger, especially when calculated from a genuinely pre-industrial base. The IPCC also keeps giving the impression that there was a carbon budget to divide among polluters, a carbon budget large enough for polluters to keep polluting for decades to come, whereas there is just a huge carbon debt for which there is no short-term remedy.

A recent analysis concludes that Arctic terrestrial permafrost now emits more greenhouse gases than it stores, and the trend is likely to accelerate as temperatures keep rising in the Arctic. The highest carbon dioxide emissions over the 2000-2020 period came from inland rivers and wildfires. The non-permafrost wetlands exhaled the most methane, and dry tundra released the most nitrous oxide.

The joint CO₂e of emissions in this analysis only cover part of global emissions, e.g. the analysis excludes emissions from Arctic subsea permafrost and from oceans in general, from many mountain areas and from the Southern Hemisphere. The study also appears to have excluded emissions caused by anthropogenic disturbances such as clear-cutting, logging and fracking activities in the region, while calculations typically use a low global warming potential (GWP) for methane (100-year horizon).

The prospect of further releases looks dire. The analysis gives estimates that the upper three meters of permafrost region soils store 1,000 Gt of soil organic carbon, while deeper deposits could store an additional amount of as much as 1,000 Gt C. The analysis concludes that the permafrost region is the largest terrestrial carbon and nitrogen pool on Earth. Miesner et al. warn that an additional 2822 Gt of organic carbon is stored in subsea Arctic shelf permafrost and Huang et al. warn that the top two meters of soil globally holds about 2300 Gt of inorganic carbon, which has been left out of environmental models, and 23 Gt of this carbon may be released over the next 30 years.

The transition from sink to source of the region is an important feedback of the temperature rise that is not fully reflected in many climate models. According to the IPCC, 14–175 Gt CO₂e (in carbon dioxide and methane) gets released per 1°C of global warming, which is likely to underestimate the situation by downplaying many feedbacks. Despite the dire situation, the IPCC keeps promoting less effective policies such as support for biofuel and fuel efficiency standards, as discussed in earlier posts such as this one.

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.

Temperature rise in the Tropics (update 5)

The temperature in the Tropics (23.5°S-23.5°N, 0-360°E) reached a new record high on April 24, 2024 of 27°C (or 80.6°F). 


The image below shows the monthly temperature anomaly over the past few years through March 2024, when the anomaly reached a record high of 1.448°C (or 2.606°F).  


Note that the anomaly in the top image is calculated from 1979-2000 as a base, while anomalies in the above image are calculated from 1951-1980 as a base. When calculated from a pre-industrial base, these anomalies will be much higher.

The high temperatures are causing widespread damage and are threatening to cause huge loss of life of people, livestock and wildlife, crop failure and ecosystem collapse in the tropics and elsewhere.
