"Real world observations tell us that the IPCC's speculative computer models do not work, ice is not melting at an enhanced rate, sea-level rise is not accelerating, the frequency and intensity of extreme weather events is not increasing, and dangerous global warming is not occurring," he said in a news release.
Possibly by 2050, reports Bill Blakemore at ABC News, as the rate of sea level accelerates; the rate has doubled in just the past 15 years.
"Climate change is becoming a big issue," he said, and the increasing rate of sea level rise could soon overtake the rate of land loss, which has historically been greater.
That may not seem like much, but the rate of sea level rise has almost doubled in recent years, and scientists expect that rate to continue to go up.
The rate of sea level rise since the mid-19th century has been larger than the mean rate during the previous two millennia (high confidence).
Ice sheets are melting at an increasing rate and sea level rise was is accelerating.
The current rate of sea level rise is ~ 3 mm/year.
However, the rate of sea level rise is dependent on location, and the absolute amount is, again, highly uncertain.
The warming oceans account for about 40percentt of that rate of sea level rise over the past two decades.
These include more extreme weather, longer and more frequent droughts and heatwaves, and a higher rate of sea level rise.
The rate of sea level rise has mysteriously slowed down in the most recent decade, for example.
