<p>Zhaohua,</p>
<p><br>
</p>
<p>Is it OK to give me a link for this talk? I didn't sleep well.
I can keep awake if I have my computer, but in the lecture hall it
would be a challenge.</p>
<p><br>
</p>
<p>Cheers,<br>

<b class="x_ContentPasted0">Abstract</b>: New regulations
from the International Maritime Organization (IMO) limiting
sulfur emissions from the shipping industry are expected to
have large benefits in terms of public health but may come
with an undesired side effect: acceleration of global
warming as the climate-cooling effects of ship pollution on
marine clouds are diminished. Previous work has found a
substantial decrease in the detection of ship tracks in
clouds after the IMO 2020 regulations went into effect, but
changes in large-scale cloud properties have been more
equivocal. Using a statistical technique that estimates
counterfactual fields of what large-scale cloud and
radiative properties within an isolated shipping corridor in
the southeastern Atlantic would have been in the absence of
shipping, we confidently detect a reduction in the magnitude
of cloud droplet effective radius decreases within the
shipping corridor and find evidence for a reduction in the
magnitude of cloud brightening as well. The instantaneous
radiative forcing due to aerosol–cloud interactions from the
IMO 2020 regulations is estimated to be of order 1 W m−2
within the shipping corridor, lending credence to global
estimates of order 0.1 W m−2 from climate models. Although
the contribution to warming since 2020 is expected to be
small globally, the effects may be much larger regionally in
the north Atlantic and Pacific. In addition to their
geophysical significance, our results also provide
independent evidence for general compliance with the IMO
2020 regulations.
