Human-caused climate change: examine the evidence yourself
We do not begin with projections or individual disasters, but with the simplest testable question: what has actually been measured? We then examine possible causes, attribution to human influence and the consequences for extreme events.
What instruments and observational records show.
Which causes explain the observed change.
What models project under clearly stated assumptions.
Four questions, one at a time
Each step stands on its own. No later conclusion is used as evidence for an earlier step.
-
01Available now
Is the climate changing measurably?
Global and European temperature records and atmospheric CO₂ concentration are plotted directly from published datasets.
-
02Next section
Can natural factors explain the trend?
Solar activity, volcanoes and internal climate variability are compared using their measured influence.
-
03Planned
How is the human contribution determined?
Physics, emissions, characteristic warming patterns and model comparisons provide independent lines of evidence.

04Planned
What does this mean for extreme events?
Long-term risk trends and studies of individual events remain separate. Where no attribution is available, we say so explicitly.
A single event is not proof of climate change
A wildfire, flood or cold winter day cannot by itself prove or disprove that the climate is changing. The live map shows events. The climate section examines long-term records and, where available, scientific attribution studies.
Every central claim remains verifiable
Charts are generated from versioned datasets, not traced from images.
Source, time period, reference period and latest value appear directly beside the chart.
Measurement uncertainty, natural variability and model ranges are not mixed into one number.
Every dataset links back to the responsible scientific institution.
