claim: I note particularly that sea-level rise is not affected by the warming; it continues at the same rate, 1.8 millimeters a year, according to a 1990 review by Andrew S. Trupin and John Wahr.
evidence: The last time the Earth was 2 °C ( 3.6 °F ) warmer than pre-industrial temperatures, sea levels were at least 5 metres ( 16 ft ) higher than now : this was when warming because of changes in the amount of sunlight due to slow changes in the Earth's orbit caused the last interglacial.
