Climate Change — Reality and Scenarios
A projection is not a prophecy; it links assumptions, models, uncertainty and observable indicators.01 · WHAT IT IS
Overview
IPCC scenarios describe conditional climate futures under different emissions and socioeconomic pathways.

65 · CLIMATE REALITY VERIFICATION
Climate Change
The reality already underway—and the future not yet fixed
This is not a prophecy with one hit-or-miss sentence. Atmospheric, ocean and cryosphere observations, causal physics, conditional scenarios and political claims belong in separate evidence boxes.01 · REALITY DASHBOARD
Five signals measured now
2025 global surface mean
Relative to 1850–1900 · centre of WMO's reported range
Hottest continuous run
2015–2025 were the eleven warmest years on record
Sea-level rise rate
2012–2025 · up from 2.65 mm/yr in 1993–2011
Ocean heat content
Global ocean heat content set another record in 2025
Atmospheric CO₂ rise
More than fifty per cent above the pre-industrial level
02 · EVIDENCE CHAIN
Independent observing systems point in the same direction
Physics
Greenhouse gases absorb outgoing infrared radiation. Laboratory spectroscopy and satellites measure that property.
Atmosphere
Surface networks, satellites and reanalyses all show long-term warming across independently produced datasets.
Ocean
The ocean takes up most of Earth's energy imbalance. Ocean heat content reveals accumulated heat more clearly than a noisy single surface year.
Ice · sea level
Glacier loss, ice-sheet mass loss, thermal expansion and satellite-altimeter sea level are linked but independently measured.
Causal fingerprints
Solar change alone cannot jointly explain tropospheric warming, stratospheric cooling, ocean heat gain and observed seasonal patterns.
03 · CERTAINTY MAP
Separate strong conclusions from conclusions that remain ranges
Observed cause
The planet has warmed and human activity is the principal cause of recent warming
Global direction
More cumulative emissions lead to more long-term warming and sea-level risk
Regional magnitude
Rain, drought and storm risks vary by region, metric and timeframe
Single-event attribution
Heat attribution is often stronger; a local storm or downpour needs a dedicated analysis
Social loss
Planning, poverty, building quality, warnings, insurance and grids change the same hazard's damage
04 · CONDITIONAL FUTURES
A scenario is a conditional statement, not destiny
IPCC AR6 values below describe 2081–2100 warming and sea level in 2100. Temperature is relative to 1850–1900; sea level to 1900.SSP1-1.9
Strong mitigation- Best estimate
- 1.4°C
- Likely range
- 1.0–1.8°C
- Sea level
- 0.28–0.55 m
Rapid cuts lower additional warming and the upper tail of end-century risk.
SSP2-4.5
Intermediate- Best estimate
- 2.7°C
- Likely range
- 2.1–3.5°C
- Sea level
- 0.44–0.76 m
Choices made now determine where the world travels through the middle range.
SSP5-8.5
Very high emissions- Best estimate
- 4.4°C
- Likely range
- 3.3–5.7°C
- Sea level
- 0.63–1.01 m
A high-emissions stress test, not an automatic baseline for every forecast.
05 · EVENT ATTRIBUTION
Climate alone does not make a disaster
Disaster loss = climate hazard × exposure × vulnerability. Climate change can alter odds and intensity; drainage, land management, construction and warnings shape the damage.Heat
Relatively strong attributionA warmer background raises the probability and intensity of many heat extremes.
Heavy rain
Strong moisture physicsBroad and long-duration signals are clearer; a short local event needs observations and modelling.
Drought · wildfire
Compound driversTemperature, soil moisture and wind interact with land management, ignition and water demand.
Tropical cyclones
Separate the metricsCounts, peak intensity, rainfall and translation speed cannot be compressed into one claim.
06 · THE U.S. ARGUMENT
Split ‘America called it a hoax’ into three different records
It is not one conclusion held by the United States or U.S. science. Trump-administration rhetoric and policy, federal scientific observations, and regional or industry interests occupy different layers.Politics · policy
The Trump administration framed the Paris Agreement as an unfair economic burden and ordered withdrawal. It also argued regulation raises energy costs and harms jobs.
Observation · science
Public NASA and NOAA observations continue to report warming, ocean heat gain and sea-level rise. Political rhetoric does not itself falsify those records.
Economy · industry
Oil and gas, power prices, vehicles, local jobs and transition costs intensify conflict. Non-fossil power employment and clean-technology industries also grew.
“Green New Scam”
Political sloganNot a measurable scientific proposition. Evaluate individual policy costs separately from greenhouse physics.
“Paris is unfair to America”
Distributional judgmentBurden sharing and competitiveness are policy disputes, not evidence against radiative forcing.
“Regulation destroys jobs”
Partly testableCount losses and gains by sector, region and period. In Dec 2025 U.S. power-generation employment was 86,000 non-fossil versus 75,000 fossil.
“Models failed, so it is a hoax”
OverstatedModels report ranges. A published audit found 63–83% of ExxonMobil's 1977–2003 warming projections accurately predicted later warming.
“It is all natural variability”
InsufficientEl Niño, volcanoes and the Sun explain fluctuations, not the full multidecadal trend and ocean heat accumulation.
“The U.S. abandoned climate action”
OvergeneralisedU.S. crude output reached a record 13.6 million barrels/day in 2025 while state, city, corporate and power-sector transitions continued.
07 · KOREA / ASIA
Korea is not waiting for a future climate
Summer 2025
Korea, China and Japan each recorded their hottest summer on record.
Asian ocean
Ocean heat content around Asia reached a record high in 2025.
Marine heatwaves
More than 10 million km² of Asian seas experienced marine heatwave conditions in July–September 2025.
Cities · power
Hot nights and cooling demand pressure health, peak electricity and vulnerable households together.
Coasts · food
Sea level, ocean temperature and extreme rain test ports, aquaculture, fisheries, drainage and farms.
08 · CLAIM CHECK
Test exaggeration from both sides by the same rules
“Climate always changes”
True premise, missing conclusionNatural variability does not exclude human forcing; rate, energy balance and causal fingerprints also matter.
“A cold day disproves warming”
Scale errorLocal weather and a multi-decade global average answer different questions.
“Scientists predicted an ice age in the 1970s”
Misrepresents the literatureThe peer-reviewed literature did not contain a dominant long-term global-cooling consensus.
“The world ends in 2030”
Unsupported deadlineAssessments describe risk ranges and pathways, not a fixed apocalypse date.
“Every flood and fire is climate change”
Single-cause errorClimate contribution, land use, preparedness, ignition and exposure must be assessed together.
“Crossing 1.5°C makes action pointless”
Threshold errorRisk rises with warming and some changes are irreversible, but every avoided increment reduces harm.
09 · METHOD
Reality-verification protocol
- 01Fix the observableName temperature, ocean heat, sea level or ice before arguing.
- 02Check the baselineRecord comparison period, spatial scale, unit and uncertainty.
- 03Cross independent recordsConnect WMO and IPCC assessments to NASA, NOAA and underlying observations.
- 04Separate cause from correlationLook for physics, fingerprints and counterfactual model tests.
- 05Keep forecasts conditionalStore pathway, period, central estimate and range together.
- 06Separate science and policyExistence, impact magnitude and policy cost require different evidence.
10 · SALGIL ASSESSMENT
Final assessment
Climate change is not a prophecy still waiting to happen. It is a reality measured across independent observing systems.
Evidence that human activity is the main cause of recent warming is strong. A single regional disaster, end-century temperature and economic loss should still be expressed as ranges conditional on scenarios and vulnerability. U.S. ‘hoax’ rhetoric is classified more accurately as a policy argument about cost, regulation, energy security and political identity—not a scientific falsification.
