The statement is not accurate.
What scientists do agree on
- There is a very strong scientific consensus that the Earth is warming and that most of the recent warming is caused by human activities (greenhouse gas emissions). Major assessments (IPCC reports) state this explicitly.
- Many observed changes—rising global average temperature, shrinking Arctic sea ice, more intense heatwaves, changing precipitation patterns, and sea level rise—are already happening.
What the statement gets wrong
- It’s not true that “all scientists” agree. Scientific consensus is very strong but not absolute; there are legitimate, ongoing debates about details (regional changes, rates for particular impacts, feedbacks and tipping points).
- Whether change will happen “rapidly” depends on what you mean by rapid and on future emissions. Some aspects (heatwaves, extreme rainfall, Arctic sea-ice loss) can and already have changed quickly. Other changes (global sea level rise, deep-ocean warming) play out over decades to centuries. Models project much faster change under high-emission scenarios than under low-emission scenarios.
Why that nuance matters
- Risk depends on both the magnitude and the rate of change. Faster change gives ecosystems, infrastructure and societies less time to adapt and increases the chance of crossing thresholds with abrupt consequences (permafrost thaw, ice-sheet collapse).
- Scientists focus on probabilities and scenarios rather than absolute certainty. The consensus is about direction and cause (warming driven by humans); the timing and speed of particular impacts have uncertainties.
If you want, I can:
- Summarize the IPCC conclusions about likely rates of change under different emissions scenarios,
- Point to studies quantifying scientific consensus (e.g., Cook et al. and follow-ups),
- Give examples of impacts that are already changing quickly and those that will unfold more slowly.
