David Walters gives us the usual litany of alarmist claims:
however, data is overwhelming from almost all of the specialists in the fields of climatology that shows we are warming.
The surface temperature record is manifestly contaminated with urban heat island effects. See the studies of Ross McKitrick.
The present observed change is not consistent with what is naturally expected.
You mean, it is not consistent with what the climate models predict. The climate models all universally predict the greatest warming to occur in the tropical troposphere. But such is not the case, hence, the models are wrong.
What’s more, the models are incapable of recreating the medieval warm period, no matter what magnitude of warming occurred. Hence, the models clearly do not include all the possible variables that can cause warming.
Greenland’s icecaps are experiencing more summer melting that has been recorded. Arctic sea ice is thinning, and open water exists where none has ever been recorded.
And what you conveniently ignore is that the “recorded history” only goes back to 1979.
Permafrost is thawing that has not ben witnessed before by natives who have lived there for millennium.
Anecdotal “data” carries very little weight in science.
Yes, there was a medieval warming, but that warming was not as warm as what we’ve experienced in the mid 20th century.
False. All such claims about past warming versus current conditions rely on proxy data, which has been shown repeatedly to have significant reliabity problems. See the work of McIntyre and McKitrick.
