What was claimed

Climate is not changing in any discernible way and emissions are having no discernible effect on the atmosphere. [...] The only fingerprint here is that of the climate hoax

Our verdict

Inaccurate

Average global temperatures have risen by approximately 1.3°C since pre-industrial times, and climate extremes of 2023–2024 were exceptional even compared to recent warming trends, with record-breaking global surface air and sea surface temperatures. This is measurable and discernible change. Atmospheric carbon dioxide reached 152% of the pre-industrial level in 2024, primarily because of emissions from the combustion of fossil fuels and cement production. Human activities (primarily the human burning of fossil fuels) have warmed Earth's surface and its ocean basins. The effect is well-documented and measurable. (Only 2 of 3 AI systems responded.)

What other AI think

Both claims in this statement are directly contradicted by overwhelming scientific evidence. Climate is demonstrably changing with measurable warming, and human emissions have a well-documented, significant effect on the atmosphere. The characterization as a "hoax" contradicts the scientific consensus held by 97-99.9% of climate scientists.

Why this verdict

  • Both claims in this statement are directly contradicted by overwhelming scientific evidence.
  • Climate is demonstrably changing with measurable warming, and human emissions have a well-documented, significant effect on the atmosphere.
  • The characterization as a "hoax" contradicts the scientific consensus held by 97-99.9% of climate scientists.

Climate is not changing in any discernible way

Incorrect99%
Average global temperatures have risen by approximately 1.3°C since pre-industrial times, and climate extremes of 2023–2024 were exceptional even compared to recent warming trends, with record-breaking global surface air and sea surface temperatures. This is measurable and discernible change.

This claim may mislead readers without added context.

Emissions are having no discernible effect on the atmosphere

Incorrect99%
Atmospheric carbon dioxide reached 152% of the pre-industrial level in 2024, primarily because of emissions from the combustion of fossil fuels and cement production. Human activities (primarily the human burning of fossil fuels) have warmed Earth's surface and its ocean basins. The effect is well-documented and measurable.

This claim may mislead readers without added context.

The only fingerprint here is that of the climate hoax

Incorrect99%
97% to 99.9% of climate scientists agree that climate change is happening and that human activity is the primary cause. The IPCC's Sixth Assessment Report states, 'It is unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times'. The scientific consensus is overwhelming and based on extensive evidence, not a hoax.

This claim may mislead readers without added context.

The statement contradicts well-established, repeatedly measured evidence. Multiple independent lines of observation link rising greenhouse gas emissions to measurable atmospheric and climate changes.

Why this verdict

  • The statement contradicts well-established, repeatedly measured evidence.
  • Multiple independent lines of observation link rising greenhouse gas emissions to measurable atmospheric and climate changes.

Claims checked

Climate is not changing in any discernible way

Incorrect95%
Global temperature records, ice loss, sea level rise, and shifting weather patterns show clear, measurable climate change over decades.

This claim may mislead readers without added context.

Emissions are having no discernible effect on the atmosphere

Incorrect95%
Atmospheric concentrations of CO2 and other greenhouse gases have risen sharply since the industrial era and are directly attributable to human emissions, altering radiative balance.

This claim may mislead readers without added context.

The only fingerprint here is that of the climate hoax

Incorrect95%
Observed fingerprints (e.g., tropospheric warming and stratospheric cooling, isotopic carbon signatures) match expected effects of greenhouse gas forcing, not a hoax.

This claim may mislead readers without added context.
