claim: Scientists were caught 'adjusting' sea level data to create false impression of rising oceans
evidence: Global average sea level has risen throughout the 20th century and continues to rise at an accelerating rate. Sea level rise primarily results from glacial ice melting and the expansion of seawater as it warms. Scientists do not arbitrarily adjust sea level data, but instead compare sea level measurements to stable benchmarks to generate accurate estimates of sea level change over time.
