OPEN WAGERS


Date for the 2024 Global Sea Surface Temperature to be Less than 2023 GSST

This is a simple over/under fake bet asking if the Global sea surface temperature in 2024 will be less than the Global sea surface temperature in 2023 on or before June 15, 2024. It is based on the expectation that the coming La Niña, predicted to begin in early June, will rapidly decrease Global sea surface temperatures.

This bet will be resolved on or before when the data for June 16, 2024 sea surface temperatures is released, using this data.

Second Wager on Date for the 2024 Global Sea Surface Temperature to be Less than 2023 GSST

This is a multiple-choice fake bet asking when the Global sea surface temperature in 2024 (GSST) will be less than the GSST in 2023. There are four wagers, each with different odds.

  1. Before June 15th (pays fake 2-to-1)
  2. June 15th to August 31st (pays fake 1-to-1)
  3. September 1 to December 31st (pays fake 2-to-1)
  4. Not in 2024 (pays fake 4-to-1)

This bet will be resolved by the end of 2024, one way or another, using this data.

New Record Global 2-meter Surface Temperature Maximum

The highest global surface temperature (GMST) ever recorded was 17.07°C on July 6, 2023. This wager is if the 2023 record will be broken in 2024.

    • 2024 GMST maximum > 2023 maximum (pays fake 1-to-2)
    • 2024 GMST maximum ≤ 2023 maximum (pays fake 2-to-1)

This wager will be resolved using ECMWF data.

New Record Minimum Arctic Sea Ice Extent in September, 2024

The all-time recorded minimum sea-ice extent for the Arctic occured on September 17th, 2021, at 3,177,455 square kilometers. This is a simple Over/Under even fake-money wager on whether this year’s minimum sea-ice extent will be above or below 3,177,455 square kilometers.

This bet will be resolved by early October 2024, using JAXA data.

Carbon Dioxide Rising 3.80 ppm from November, 2023 to November, 2024

Carbon dioxide tends to spike the year after an El Niño begins. There were huge spikes in 1998 and 2016, following the major El Niños of 1997 and 2015. The spike in 2016 was nearly 3.50 ppm.

This is a simple over/under even money fake bet on whether Mauna Loa carbon dioxide will rise 3.80 ppm from November 2023 to November 2024. This bet will be resolved in early December, 2024, after the data is published.

Global Temperatures Anomaly Rising 1.5°C for the full year 2024

Given the 50% chance of the return of El Niño by late 2023, do you think the global mean surface temperature (GMST) for 2024 will break 1.5°C above the 1850-1900 IPCC baseline? This fake bet pays fake even money for a correct answer.

This bet will be resolved in early 2025, after the data is published.

Here is a record of the Twitter betting: Twitter Link


Global Temperature Anomaly Rising 1.7°C for the full year 2024

Given the return of El Niño in 2023 and prediction for a very strong El Nino in late 2023, do you think the global mean surface temperature (GMST) for the entire year 2024 will break 1.7°C above the 1850-1900 IPCC baseline? This fake bet pays fake 10-to-1 for the over and fake 1-to-10 for the under

This bet will be resolved in early 2025, after the data is published.

Global Temperature Anomaly Rising 1.75C for the full year 2024

This is a follow-up wager to the wager above, which gave 10-to-1 odds for 1.70°C for the full year 2024. This wager is an even money over/under of 1.75°C for the entire year 2024 (ERA5 data).

This bet will be resolved in early 2025, after the data is published.

Here is a record of the Twitter betting: Twitter Link


Global Temperature Anomaly Horse Race for the full year 2024

Given the ongoing El Niño, and that this year is at least 1.46°C above the IPCC 1850-1900 baseline, what do you think the global temperature anomaly for 2024 will be?

    • Below 1.50°C (pays 4-to-1)
    • 1.50°C – 1.59°C (pays 1-to-1)
    • 1.60°C – 1.75°C (pays 1-to-2)
    • 1.76°C and above (pays 3-to-1)

This bet will be resolved in early 2025, after the data is published.

World Population on January 1, 2026

An even-money bet on the world population being over or under 8 billion on January 1, 2026.

An extinction-level wager on the world population being under 2 billion on January 1, 2026.  This wager pays 1000-to-1 (the maximum odds this casino permits). In other words, a $1 wager wins you $1000 if there are fewer than 2 billion humans on the planet on January 1, 2026.

Wagers will be settled based on the data posted here: https://www.census.gov/popclock/world


Global Mean Surface Temperature Anomaly for 2025

This is a simple over/under fake bet that the year 2025 will be 1.45°C or higher above the 1850-1900 IPCC pre-industrial baseline (using Copernicus ERA5 data).

Here is a record of Twitter betting.


World Cup in 2026

The World Cup is scheduled to take place in North America in 2026. Many believe that civilization won’t last long enough for the next World Cup to take place. Will there be a World Cup in 2026?

Betting on “No” pays 6-to-1, your $1 fake bet will win fake $6 if no World Cup takes place in 2026.

Betting on “Yes” pays 1-to-6, your $1 fake bet will win fake $0.17 if a 2026 World Cup happens.

Wagers will be settled based on the data posted here: Twitter Link


12-Month Running Mean for Global Temperatures Breaks 2.0C above Pre-industrial Baseline by Dec. 31, 2028

When the dust settles on the current El Niño (posted in early 2024), we’re almost certain to see a 12-month running mean for the global temp of 1.6°C or more above the 1850-1900 pre-industrial. This is a simple over/under fake bet on the 12-month running mean breaking 2.0°C.

This wager will be decided using Copernicus ERA5 data (or whatever the latest dataset Copernicus is publishing at the time), which includes the Copernicus 1850-1900 baseline, on or before January 1, 2029.

Lake Mead in the US going Dead Pool by 2030

Lake Mead, on the border of Arizona and Nevada, supplies power and water to millions in the Southwest US.  Water levels have been decreasing year over year at a rate of about 20 feet per year.  Today the level is at about 1040 feet.  Dead pool is the water level at which water can no longer flow out of the dam, leaving millions without power and water. For Lake Mead, this level is 895 feet.

This wager is when Lake Mead will go dead pool. It is an even money bet with an over/under of the year 2030.  The “Under” bet wins if dead pool happens by December 31, 2029.  The “Over” bet wins if dead pool happens after January 1, 2031.  All wagers lose if dead pool happens in 2030.

Global Temperatures Exceeding 60°C = 140°F by January 1, 2030

We are now routinely seeing world temperatures that exceed 52°C. In 2021, the high temp was 54.4°C.  As the planet heats up, new record highs should occur. This is a wager when the first WMO recognized high temperature will equal or exceed 60°C = 140°F.  This wager wins and pays even money if 60°C occurs on or before December 31, 2029.


Blue Ocean Event by January 1, 2030

Will JAXA or NSIDC data show less than 1 million square kilometers of Arctic sea-ice extent before 2030 (one of the years 2022-2029)? This very long-term wager pays even money.


Total Sea Level Rise by January 1, 2040

This is my longest-term wager.

First, there is an “over” wager that pays 2-to-1 if global sea-level rise is greater than or equal to 14 inches (355 mm) between the period January 1, 2000 to January 1, 2040.

Second, there is an “under” wager that pays 1-to-2 if global sea-level rise is less than or equal to 10 inches (254 mm) between the period January 1, 2000 to January 1, 2040.

All wagers lose in the event global sea-level rise is between 10 inches and 14 inches.

Wagers will be settled based on this (or similar) US government data:

Peak Global CO₂ (approx. 2040-2050)

At some point global CO₂ will peak. This will happen for one of two reasons. Either there will be an effective reduction in CO₂ emissions to the point where net-0 is reached (currently predicted to be somewhere in the range of 2050-2070), or else global industrial civilization will collapse so that very little CO₂ is being emitted by humans. Combining the efforts of humans to reduce CO₂ emissions with the demise of global industrial civilization, the climate casino is offering an over/under of global CO₂ at 450 ppm, which will likely happen somewhere in the range 2040-2050.

This is an over/under wager with an unknown timeline.  You can fake wager that CO₂ will peak over 450 ppm or under 450 ppm. Each of these pays fake even-money.  Wagers will be settled based on this (or similar) NOAA data:

Human Population Minimum in the Decade 2050-2059

This is not a wager, but is the climate casino’s answer to the question of predictions for the future of humans on this planet. The climate casino is giving an over/under of 4 billion humans for the minimum human population reached during the decade 2050-2059.


RESOLVED WAGERS


Maximum Mauna Loa Monthly Carbon Dioxide Reading in 2024

This bet has been resolved. The “OVER” bet is the winner. The CO₂ reading for May, 2024 was 426.90 ppm.

  • 434 took the OVER, winning $434 fake dollars.
  • 133 took the UNDER, losing $133 fake dollars.
  • The climate casino LOST $301 fake dollars.

This is a simple over/under bet on the monthly average for May, 2024 (typically the yearly maximum). The line is set at 426.80 ppm, and the data used will be NOAA’s monthly reading, published here.

The May, 2024 reading will be published typically around June 5-8. It is also possible that the maximum will be hit in April’s reading (out around May 5-8). In any event, this wager should be fully finalized by early June, 2024.

Maximum Global Temperature Anomaly above 2.35°C by May 1, 2024.

This bet has been resolved. The “UNDER” bet is the winner. The actual maximum global 2-meter surface temperature anomaly was 2.06°C, on November 18th, 2023.

  • 279 took the OVER, losing $279 fake dollars.
  • 201 took the UNDER, winning $201 fake dollars.
  • The climate casino WON $78 fake dollars.

This even money fake wager is on the maximum global 2-meter temperature anomaly hit at the height of the current El Nino. We already hit a 2.05°C anomaly twice in 2023. I’m setting the over/under max anomaly at 2.35°C, before May 1st, 2024, using Copernicus ERA5 data.

Here is a record of the Twitter betting: Twitter Link


Maximum Global Sea Surface Temperature above 21.40°C by May 1, 2024

This bet has been resolved. The “UNDER” bet is the winner. The actual maximum global sea surface temperature was 21.17°C on April 24th.

  • 518 bet on the OVER, losing $518 fake dollars.
  • 124 bet on the UNDER, winning, $124 fake dollars.
  • The climate casino WON $394 fake dollars.

This even money fake wager is on the maximum global sea surface temperature (SST) reached by the end of April, 2024. As this wager was posted, global SSTs were running about 0.40°C above 2023 levels. The 2023 peak in April was 21.05°C, hence this wager is setting a reasonable over/under of 21.40°C.

Here is a record of the Twitter betting: Twitter Link


Maximum Tropical 2m Temperature Over/Under 27.24°C by May 1, 2024

This bet has been resolved. The “UNDER” bet is the winner. The maximum tropical 2-meter temperature reached was 26.94°C on April 24, 2024.

  • 407 wagered on the OVER, losing $407 fake dollars.
  • 109 wagered on the UNDER, winning $109 fake dollars.
  • The climate casino WON $298 fake dollars.

This even money fake wager is on the maximum tropical 2-meter temperature by May 1, 2024 (or soon after).

On average, Tropical 2m temps peak on Apr. 22, with an average gain from Mar. 13 to Apr. 22 of 0.36°C. The 2m temp on Mar. 13 was 26.87°C. So I am setting an over/under line of 27.24°C for the peak Tropical temperature this year.

Global Temperatures Anomaly Rising 1.3°C for the full year 2023

This bet has been resolved. The “OVER” bet is the winner. The average for 2023 will be at least 1.46°C.

  • 141 wagered on the OVER, winning $141 fake dollars.
  • 42 wagered on the UNDER, losing $42 fake dollars.
  • The climate casino LOST $99 fake dollars.

Given the 50% chance of the return of El Niño by late 2023, do you think the global mean surface temperature (GMST) for 2023 will break 1.3°C above the 1850-1900 IPCC baseline? This fake bet pays fake even money for a correct answer.

This bet will be resolved in early 2024, after the data is published. (Resolved 12/21/2023)

Global Temperatures Breaking the previous all time record anomaly of 1.21°C for the full year 2023

This bet has been resolved. The “YES” bet is the winner. The average for 2023 will be at least 1.46°C.

  • 160 wagered on YES winning $40 fake dollars.
  • 32 wagered on NO losing $32 fake dollars.
  • The climate casino LOST $8 fake dollars.

Given the 50% chance of the return of El Niño by late 2023 and the implied heating from the Hunga-Tonga volcanic eruption, do you think the global mean surface temperature (GMST) for 2023 will break the previous record of 1.21°C above the 1850-1900 IPCC baseline?

Given the facts on the ground, this wager has some pretty stiff odds.  The “Over 1.21°C” wager pays 1-to-4.  A $1 fake-bet will pay $0.25.  The “Under 1.21°C” wager pays 4-to-1.

This bet will be resolved in early 2024, after the data is published. (Resolved 12/21/2023)

El Niño for the three month period Aug/Sep/Oct 2023

This bet has been resolved. The “YES!” bet is the winner. The average for the three month period Aug/Sep/Oct was 1.5°C and was officially an El Niño according to NOAA.

  • 102 wagered on YES, winning $34 fake dollars.
  • 30 wagered on NO, losing $30 fake dollars.
  • The climate casino LOST $4 fake dollars.

  • 358 took the OVER, losing $358 fake dollars.
  • 97 took the UNDER, winning $97 fake dollars.
  • The climate casino WON $261 fake dollars.

This is an even-money wager that on some day in 2023 the global 2 meter temperature will exceed 17.25°C. The previous record is 16.924°C set in 2022.

This bet will be resolved in late 2023, after the peak temperature for the year has been reached, or any time the temperature is equal to or greater than 17.25°C.

Arctic Sea-Ice Maximum is a New Record Low Maximum

This bet has been resolved. The “OVER” bet is the winner.

  • 75 bet the UNDER, losing $75 fake dollars.
  • 40 bet the OVER, winning $40 fake dollars.
  • The climate casino WON $35 fake dollars. 

We are nearing the annual Arctic sea-ice maximum. Using JAXA data, the previous all-time record low sea-ice maximum happened on March 6, 2017 with an extent of 13,878,287 km². As of this wager on January 25, 2023, Arctic sea-ice extent is 13,106,264 km² and ranks 3rd lowest overall for the date.

The wager is if this year’s maximum will be lower than the record low maximum from 2017.  The wager will be resolved either when this year’s sea-ice extent exceeds 13,878,287 km² or April 1, whichever comes first.  This is an even-money over/under bet.
