The TULIP Score is a 1–10 urgency rating for climate and environmental problems. It combines evidence about how serious a problem is now, how close it is to a dangerous level, whether it is getting worse, and how widely it is happening.
TULIP prefers recent, global measurements. When those are available, it asks four questions: How large is the problem now? How close is it to a dangerous threshold? How quickly is it changing? How much of the world does it affect?
If current measurements are incomplete, TULIP uses documented harm that has already occurred—to natural systems, people, and the economy. A model estimate is used only as a last resort and is clearly marked Modeled.
Climate problems are measured in incompatible units: degrees of warming, tonnes of pollution, hectares lost, people exposed, or dollars of damage. Before combining them, TULIP translates every measurement to a common 0–1 scale.
0 means the reference condition. About 0.33 means concerning. About 0.67 means critical. 1 means extreme. A measurement between two points receives a value between them. This translation makes different kinds of problems comparable without pretending that their original units are the same.
For issues with current data, the four signals do not count equally. Current magnitude counts for 30%, dangerous-threshold position for 30%, momentum for 25%, and geographic extent for 15%.
In shorthand: (magnitude × 0.30) + (threshold × 0.30) + (momentum × 0.25) + (extent × 0.15) = the weighted composite.
When TULIP has to use documented harm instead, the blend changes to 35% physical or ecological harm, 30% harm to people or the economy, 20% persistence, and 15% geographic extent. The result is still a weighted composite between 0 and 1.
The weighted composite is still between 0 and 1. To turn it into the familiar TULIP scale, multiply it by 9 and add 1: TULIP Score = 1 + (9 × weighted composite). Multiplying by 9 stretches the range from nine points wide; adding 1 shifts it from 0–9 to 1–10.
The result is rounded to one decimal place. 1.0–2.9 is Low, 3.0–4.9 is Elevated, 5.0–6.9 is Rising, and 7.0–10.0 is Critical.
For Global Temperature, TULIP translates the evidence into four 0–1 values: 0.62 for current magnitude, 0.62 for threshold position, 0.71 for momentum, and 1.00 for global extent.
Apply the weights: (0.62 × 0.30) + (0.62 × 0.30) + (0.71 × 0.25) + (1.00 × 0.15) ≈ 0.70. That 0.70 is the weighted composite, not the final score.
Convert it to 1–10: 1 + (9 × 0.70) = 7.3. Global Temperature therefore receives a TULIP Score of 7.3, or Critical.
A 7.3 does not mean 73% damage or a 73% chance of disaster. It means the available evidence places the issue high on TULIP's urgency scale. The score also does not measure scientific confidence, popularity, or how easy the issue is to solve.
Receipt verification is computational, not scientific proof. It checks that stored components reproduce the score and band and that hashed content has not changed. Scientific review separately evaluates the measurement, anchors, transformation, scoring route, and continuing source support.
The TULIP Project helps people understand how human choices affect Earth’s atmosphere, oceans, ecosystems, economies, and future.
It brings climate data and interconnected relationships into one explorable system.
This makes complex causes and consequences easier to understand without reducing them to a single story.
TULIP combines public datasets, institutional monitoring, reported disclosures, and modeled relationships.
Not every connection carries the same level of certainty, and TULIP is not a substitute for primary scientific institutions.
