It's also time-dependent. Roger's not the only one who can draw pretty

how useful a linear trend line is, depending on what you want to show. The
data is from Roger's thoughtfully provided source. I added another trend
line that's probably a little more representative of what's been happening
lately.

You're cherrypicking, again
R^2=0.0075 means nothing.

So are you. You're using an entire record to show "continued warming", when
clearly, the latest records do not show that it's "continuing".

So, what "falcon" is saying is that since last night was cold, the
northern hemisphere has some how skipped summer and fall and gone
straight back to winter: THE LATEST DATA SHOWS IT.

Goopd bloody gods.

Why are you continuing with this "canard" ? The latest records can
show neither warming, cooling or flat, because the scatter about any
trend line drawn, however robust that might be in statistical terms,
is too great to allow meaningful inference.

But he knows that fact already; he just does not give a ****.

Data for the last twenty years allows meaningful inference. It shows
warming is highly likely to have taken place. Data for the last thirty
years shows warming to be so likely, that any proposal it has not
warmed would be unthinkable.

With the March data now published, the statistical significance is
now.... (Excel Spreadsheet)... 97.63% confidence that
unprecedented global warming has happened. That is a drop from
97.71% three months ago.

At this rate, in 300 years the confidence will dropped almost to zero!!
;=))

Proof we don't need to worry about it! Whew.
