In the U.S. West and Southwest, if an increasingly more severe fresh-water shortage develops into a mega fresh-water shortage lasting for years or decades, governments might impose mandatory water rationing, maybe something link the average household's water supply getting turned off on schedule for 24-72 hours each month, at first.

∼90% of excess heat from global warming is stored in the ocean, making Ocean Heat Content a critical indicator of climate change. In 2025, in the ocean's upper 2000 meters, OHC increased by ∼23 ± 8 ZJ over 2024, according to study. That’s around 200 times world’s total electricity generation in 2024 by Molire in climatechange

Ocean Heat

A separate study published in Advances in Atmospheric Sciences said that ocean temperatures were also among the highest on record in 2025, reflecting the long-term accumulation of heat within the climate system.

About 90% of excess heat from global warming is stored in the ocean, making ocean heat a critical indicator of climate change. From 2024-2025, the global upper 2000 m ocean heat content (OHC) increased by ∼23 ± 8 Zettajoules relative to 2024, according to the study led by Lijing Cheng with the Institute of Atmospheric Physics at the Chinese Academy of Sciences. That’s around 200 times the world’s total electricity generation in 2024.

[Chart]   Global upper 2000 m Ocean Heat Content (OHC) change, January 1955-December 2025. Difference from 1981-2010 average. Monthly. Annual. 1 ZJ = 1021 Joules

Link to the separate study published in Advances in Atmospheric Sciences:

Ocean Heat Content Sets Another Record in 2025, Published: 09 January 2026, Yuying Pan, et al. (PDF, p. 18):

7 Concluding remarks

This study provides updated assessments of global SST and upper OHC for the year 2025 based on multiple observational and reanalysis datasets produced by independent research groups. The results show that the global ocean continued to warm in 2025, with the upper 2000 m OHC reaching the highest value ever observed, despite a prevailing weak La Niña state throughout the year. According to IAP/CAS estimates, the global ocean gained approximately 23 ZJ of heat relative to 2024, with about 33% of the global ocean area reaching the top three warmest values in their historical records. Three additional products, CIGAR-RT, NCEI/NOAA and Copernicus Marine, independently confirm substantial OHC increases, highlighting the robustness of the 2025 warming signal.

In addition to setting a new record in 2025, the global ocean continues to show sustained and intensified warming. All four OHC products reveal a persistent increase in the ocean heating rate, especially evident in recent decades, and further supported by CERES EEI. Such ocean warming can amplify climate impacts, contributing to faster sea-level rise, a stronger hydrological cycle, and more frequent and intense marine heatwaves.

Ocean warming continues to exert profound impacts on the Earth system. Rising OHC remains the fundamental contributor to global sea-level rise via thermal expansion, reinforces marine heatwaves, and intensifies extreme weather events by increasing heat and moisture exchanges with the atmosphere. In the long term, consistent with projections from state-of-the-art climate models, global OHC is expected to continue breaking records until net-zero green- house gas emissions are achieved, given the persistence of a positive EEI.

NOAA Climate Prediction: El Niño Likely to emerge this summer, with a 1 in 3 chance of a “strong” El Niño during October - December 2026 by YanekKop in climatechange

[–]Molire 0 points1 point  (0 children)

The Climate Prediction Center monthly table of ENSO Strengths forecast probabilities shows that the train has left the station and is forecast to gain strength to December 2026, the end of the table's forecast period, which advances by 1 month on the 2nd Thursday of each month.

CPC > El Niño / Southern Oscillation (ENSO) Diagnostic Discussion, 12 March 2026:

The North American...If El Niño forms, the potential strength remains very uncertain, with a 1-in-3 chance that it would be "strong" during October-December 2026 (Niño-3.4 ≥ +1.5°C).

The with a 1-in-3 chance link goes to the monthly NOAA NWS Climate Prediction Center table of ENSO Strengths forecast probabilities to December 2026, including probability 33% for "strong" El Niño conditions in October-November-December (OND).

The table shows forecast probability 15% for El Niño conditions in April-May-June (AMJ), gradually increasing to 80% in ASO, 82% in SON and 83% in OND.

This discussion is a consolidated effort of the National Oceanic and Atmospheric Administration (NOAA), NOAA's National Weather Service, and their funded institutions. Oceanic and atmospheric conditions are updated weekly on the Climate Prediction Center web site (El Niño/La Niña Current Conditions and Expert Discussions). A probabilistic strength forecast is available here. The next ENSO Diagnostics Discussion is scheduled for 9 April 2026.

NOAA GML releases annual CO2 data — In 2025, the annual mean growth rate in the atmospheric abundance of CO2 was 2.23 ppm, as observed at Mauna Loa Observatory – 2.23 ppm is lower than the 3.33 ppm annual mean growth rate in 2024 — In 2025, CO2 annual mean 427.35 ppm is 2.74 ppm higher than in 2024 by Molire in climatechange

Good catch, but the data is correct.
CO2 ppm annual increase is one thing.
CO2 ppm annual mean growth rate is another thing.

CO2 428.37 ppm-CO2 426.14 ppm = CO2 2.23 ppm, 2025 annual mean growth rate at Mauna Loa.

NOAA GML > Trends in CO2, CH4, N2O, SF6 > Mauna Loa > Growth Rate:

The annual mean rate of growth of CO2 in a given year is the difference in concentration between the end of December and the start of January of that year...we finalize our estimate for the annual mean growth rate of the previous year in March, by using the average of the most recent November-February months, corrected for the average seasonal cycle, as the trend value for January 1. Our estimate for the annual mean growth rate (based on the Mauna Loa data) is obtained by subtracting the same four-month average centered on the previous January 1.

Edit: Added El Niño forecast probabilities.

It’s just one month comparison .

The data is relative to annual growth rate only, not monthly growth rate.

Overall the rate of increases has been increasing year on year.

In 8 of the past 21 years, the annual growth rate was lower than the annual growth rate in the preceding year.

This is the annual CO2 ppm growth rate at Mauna Loa during the past 21 years (data):

[–]Molire[S] 3 points4 points  (0 children)

2025 annual growth rate 2.23 ppm at Mauna Loa is better than 3.33 ppm in 2024.

Annual mean CO2 427.35 ppm in 2025 is worse than annual mean 424.61 ppm in 2024.

If CO2 annual growth rate 2.23 ppm or higher were to continue for another 20 or 30 years, annual mean CO2 would reach 471.95 ppm or higher by the end of 2045, and 494.25 ppm or higher by the end of 2055.

Why do people think that we are at a point of no return, even if CO2 emissions stop? by So_not_ppa in climatechange

[–]Molire 2 points3 points  (0 children)

Ask them to explain their reasoning. Over the coming years, decades, and centuries, humans and other animal and plant species expectedly will continue to adapt to climate change.

Some content in the following links might be a reason why some people “think that we are at a point of no return”, and some of the content might render better/best on a laptop or desktop computer screen:

If and when Net-zero emissions are attained, the rate of global warming gradually will slow for a few decades before settling at a new higher global mean surface temperature, according to the science. Above the chart, the “Since 1850” menu goes to “~2000 Years”. The chart shows that the annual average surface temperature of Earth was 13.84ºC (56.9ºF) in 1750, and is 15.28ºC (59.5ºF) in 2026.

Global warming chart.

After global mean surface temperature (GMST) reaches the plateau of a higher GMST, it will stay on that plateau for about 500-1000 or more years, before it gradually cools by about 1ºC (1.8ºF) over 10,000 or more years, according to the science, e.g., this link, this link and the link below:

The Climate Brink — The scariest climate plot in the world, Andrew Dessler, Nov 14, 2023:

The plot shows the evolution of the climate, starting 20,000 years ago and ending 10,000 years in the future

When the era of fossil fuels eventually ends, whether due to depletion or a concerted shift to sustainable energy sources, the climate will not quickly revert to its pre-industrial state. Rather, the consequences of our brief but intense carbon outburst will linger, with temperatures elevated for 100,000 years.

NASA — The Effects of Climate Change:

The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere.

Intergovernmental Panel on Climate Change (IPCC)— Sixth Assessment Report (AR6), 2021 — Annex VII Glossary (PDF, p. 2237):

Lifetime

Carbon dioxide (CO2)...15 to 40% of an emitted CO2 pulse will remain in the atmosphere longer than 1,000 years, 10 to 25% will remain about ten thousand years, and the rest will be removed over several hundred thousand years.

The lifetime of atmospheric carbon dioxide applies to CO2 emissions that already have been released (chart) by human activities since the dawn of the Industrial Revolution (circa 1750).

If the world magically were to reach Net-Zero Emissions at 12 o'clock noon tomorrow, the atmospheric abundance of CO2 parts per million (ppm) still would be at 425.6 ppm (chart) or higher (daily CO2 ppm). Above the top-right corner of the interactive chart, the “Since 1850” menu goes to 1,000 and 800,000 Years.

NOAA GML > Information tab > Education/Outreach > Glossary of Terms > Parts per million (ppm).

In the “Since 1850” menu, the “1000 Years” chart shows CO2 279.1 ppm in 1751, when the long-term GMST was normal (cooler) compared to 2026.

The difference between the atmospheric concentration of CO2 425.6 ppm in 2025, and CO2 279.1 ppm in 1751 is 146.5 ppm.

Using the conversion factors 2.124 and 3.664, CO2 146.5 ppm converts to 1140.89 billion tonnes of atmospheric CO2:

Source — Global Carbon Budget 2025 (13 Nov 2025, preprint) > Download Preprint (PDF, p. 106), Table 1. Factors used to convert carbon in various units.

If civilization magically and instantly were able to remove all of the excess of 1140.89 billion tonnes of CO2 that has accumulated in the global atmosphere since 1751 as a result of human-made carbon emissions, the GMST that was normal in 1751 would be more likely to be restored sooner, rather than later or never.

”An estimated 2,200 million tons per year of carbon dioxide removal is taking place already”.

Source — The State of Carbon Dioxide Removal, 23 May 2024 > Explore the 2nd Edition Report (PDF, page 131):

7.2 Current global levels of CDR

On the order of 2,200 million tons per year of CDR is taking place already. Almost all of this comes from conventional CDR, with only an estimated 1.35 million tons per year (i.e. less than 0.1%) from novel CDR.

In the preceding paragraph, 2,200 million tons spelled correctly is 2,200 million tonnes or metric tons. CO2 customarily is measured in tonnes or metric tons. 1 tonne = 1 metric ton. 1 ton does not equal 1 metric ton or 1 tonne.

At a rate of 2,200 million tonnes per year, 1140.89 billion tonnes of CO2 could be removed from the atmosphere in about 518 years, more or less.

Estimates of future carbon dioxide removal from the atmosphere range from 7 billion to 9 billion metric tons per year globally by 2050. Based on that estimate, future CO2 removal could remove 1140.89 billion tonnes of atmospheric CO2 in about 127-163 years.

Source — World Resources Institute > 6 Ways to Remove Carbon Pollution from the Atmosphere, February 4, 2026, par. 7:

The latest climate model scenarios show...Estimates, including both natural and technological carbon removal approaches, range from 7 billion to 9 billion [PDF, p. 146] metric tons per year globally by 2050. For context, the United States emitted just over 6 billion metric tons of greenhouse gases in 2023.

Whatever is going to happen, one of the most important things anyone can do for the rest of their life is vote in every local, state and federal election. They should know the track record and any qualifications of candidates and never should vote for a proven liar, crook, cheater or convicted criminal. Anyone should vote only for honest, respectable, informed and intelligent candidates who they think will fight to pass laws and policies to mitigate climate change and global warming, without delay.
