<h1>Marine Ecosystems Are Preparing
for Climate Change</h1>
<p class="subtitle">Coral reefs, kelp
forests and other ocean ecosystems may be more resilient than we
think</p>

reefs, kelp forests and other marine ecosystems may be tougher than we
give them credit for, a new study suggests. While countless scientific
reports have documented the ravages of climate change on oceanic life,
a survey of the researchers who wrote them provides a silver lining:
An overwhelming majority noticed examples of sea life withstanding
climate change.
<p>"There are instances where sensitive
ecosystems have shown remarkable resilience after climatic events. You
can think of them as 'bright spots': They demonstrate that there are
conditions under which ecosystems can persist even with major climate
disturbances," said Jennifer O'Leary, a marine conservation biologist
with California Polytechnic State University and leader of the
study.</p>

<p>The results of the survey were compiled
in a report published in the journal BioScience. In all, 97
researchers were polled; 80 percent of those who had witnessed
climatic disturbances also reported noting instances of resilience. A
similar survey that looked at expert-recommended papers on ecosystems
found examples of resilience in 85 percent of them.</p>
<p>In Western Australia, for instance, a
reef lost 90 percent of its live coral after a bleaching event. But 12
years later, it had restored itself to 44 percent of its normal size.
Meanwhile, after an El Niño-related current destroyed kelp forests off
California's coast, they were able to bounce back within half a
decade.</p>
<p>Identifying examples of resilience and
highlighting the reasons behind it could prove to be a valuable
blueprint for conservation experts, said O'Leary. It could provide
them information on local conditions that could bolster ecosystems and
guide their strategies to protect them.</p>

<h1>"Snow Moon" Lunar Eclipse Shines

45P/Honda-Mrkos-Pajdusakova, which entered the media spotlight in
December as the "New Year's Eve comet" when it first became visible,
makes its closest approach to Earth on Saturday (Feb. 11). While the
comet has been visible for months, this weekend skywatchers will have
the best possible view of the blazing space rock. It will also be the
closest comet encounter in over 30 years, so it's certainly a must-see
for avid skywatchers. Look for Comet 45P in the eastern sky before
