Over the past weekend, every time that I looked at the message board, I'd been logged out.

They are, in fact, monthly.
Eventually, all restart files will lose their sequence numbers and be identified with ".restart".

Carbon dioxide levels often hit lows,
in September, but now remain above a crucial benchmark.

In the centuries to come, history books will likely look back on,
September 2016 as a major milestone for the world’s climate.
At a time when atmospheric carbon dioxide is usually at,
its minimum, the monthly value failed to drop below 400 parts per million.

That all but ensures that 2016 will be the year that carbon dioxide,
officially passed the symbolic 400 ppm mark,
never to return below it in our lifetimes, according to scientists.

Because carbon pollution has been increasing since,
the start of the Industrial Revolution and has shown no signs,
of abating, it was more a question of,
“when” rather than “if” we would cross this threshold.
The inevitability doesn’t make it any less significant, though.

September is usually the month when carbon dioxide,
is at its lowest after a summer of plants growing and sucking,
it up in the northern hemisphere.

As fall wears on, those plants lose their leaves,
which in turn decompose, releasing the stored carbon dioxide,
back into the atmosphere. At Mauna Loa Observatory,
the world’s marquee site for monitoring carbon dioxide,
there are signs that the process has begun
but levels have remained above 400 ppm.

if the researchers don't get their results in a reasonable time, they can just re-issue them (plus a few more perhaps), as a new batch, and then forget about the earlier unreturned tasks.
