However, the winter maximum extent has been lower during the last six winters than at any other time during thirty years
of satellite records.
In relying
on satellite records since 1994 we are further losing the context of these long term changes.
If you are discussing temperature
with satellite records in mind, then 1970 is the correct starting point as that's when the first satellites were available.
This theory doesn't account for the fact that
satellite records reveal that global temperatures have been flat over most of the past two decades despite higher atmospheric CO2 levels.
Obviously given the size of the temperature spike in the
monthly satellite record for 1998, it may be some time before this measurement is beaten.
Presumably this must be online so you can sit in your chair and carry out your own research into
pre satellite records.

in satellite records of ocean chlorophyll and productivity.
The polar vortex that swirls around the South Pole is not just stronger than it was
when satellite records began in the 1970s, it has more convergence, meaning it shoves the sea ice together to cause ridging.
Antarctica's ice shelves are shrinking at an accelerating rate, one of the
longest satellite records of ice thickness reveals.
When Dr. Lindzen first published this theory, in 2001, he said it was supported
by satellite records over the Pacific Ocean.
Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long -
term satellite record in the late 1970s.
One example taken at random, is in relation to the
MSU satellite record (which we've discussed here before, so skip this next section if you've heard it all already).
Suffice it to say that the more
recent satellite recordings do confirm a warming of the air until recently, albeit less than suggested by surface records and far less than that anticipated by climate models.
Since last fall, Arctic ice has been expanding faster than at any time since
satellite records became available in 1979.
