Extrapolating based on date
from 1980 to the present yields and estimate around the 2040 for zero September

The same issues have dogged other attempts by climate scientists to glean clues on climate

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside
from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global
trend); otherwise it was always my understanding that the albedo feedback was key (while sea
ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat
from the albedo feedback, and this is released in the cold part of the year when
ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

ice core
trends).
However, during the mid-2000s, with several fewer years in the observational record, the

This means that the current warming
trend is qualitatively different
from those we can study through
ice cores etc., even if past warming was amplified by a CO2 feedback.
Over all, the analysts as a group see no deviation

Neil confronted them with the claim that the Antarctic
ice is getting thicker, and asked them to explain how this was compatible with global warming; he also talked about mean temperatures and the
trend in the same since 1998 (see the programme

from about 9m 15s in).
The researchers also found no predictive value in seeking insights

The latest research shows that while a decades - long

ice provides a 2500 year perspective indicating we headed into a mini-
ice-age as happened

from the 1200 or so floating buoys around the world's oceans are likewise showing a cooling
trend, and have been for some time.
