How High Could the Tide Go?
"In
previous research,
scientists have determined that when the earth warms by only a couple
of degrees Fahrenheit, enough polar ice melts, over time, to raise
the global sea level by about 25 to 30 feet.
But in the coming century, the earth is expected to warm more than
that, perhaps four or five degrees, because of human emissions of
greenhouse gases.
Scientists
say it has been difficult to get people to understand or focus on the
importance, for future generations, of today’s decisions about
greenhouse gases. Their evidence that the gases represent a problem
is based not just on computerized forecasts of
the future, as is commonly believed, but on what they describe as a
growing body of evidence about
what occurred in the past.
To
add to that body of knowledge, Dr. Raymo is studying geologic history
going back several million years. The earth has warmed up many times,
for purely natural reasons, and those episodes often featured huge
shifts of climate, partial collapse of the polar ice sheets and
substantial increases in sea level.
“I
wish I could take people that question the significance of sea level
rise out in the field with me,” Dr. Raymo said. “Because you just
walk them up 30 or 40 feet in elevation above today’s sea level and
show them a fossil beach, with shells the size of a fist eroding out,
and they can look at it with their own eyes and say, ‘Wow, you
didn’t just make that up.’"

Obama's Climate Challenge
"I
think the president understands the climate crisis intellectually,
but he has not had the 'holy shit' moment you arrive at when you
think about this deeply enough," says a leading climate advocate
who has had private conversations with Obama about global warming.
Instead of talking about the risks of climate change during the
campaign, Obama touted an "all of the above" energy plan
that was a soft-porn version of "drill, baby, drill." Under
Obama, in fact, oil and gas production have soared: Last year, U.S.
oil production grew by 766,000 barrels a day, the largest jump ever,
and domestic oil production is at its highest level in 15 years.
Obama,
who prides himself on his pragmatism and willingness to compromise,
may also be ill-suited to address such an urgent and unyielding
crisis – especially because it would mean taking on the
climate-denying Republican majority in the House. "Climate is
the toughest issue to get any cooperation from Republicans on,"
says Podesta. In fact, House Republicans see climate change as a
wedge issue, the atmospheric equivalent to abortion, which allows
them to collect mountains of cash from oil-industry magnates like the
Koch brothers while painting themselves as defenders of free
enterprise.
"You
can't continue with business as usual and pretend you are dealing
with the problem," says former Sen. Tim Wirth, who now heads the
United Nations Foundation. "It requires a fundamental
realignment of how you think about everything, from national security
to agriculture to economic investment. Climate change is not one of
those issues you can deal with in a few tactical moves."

Photographing Climate Change
Click here to view the blog/slideshow from our friend Rachelle Klapheke at The New Yorker
Climate
change is not only a major issue for scientists and politicians but
for artists as well. Here are ten examples of photographers and other
visual artists who are challenging viewers to consider the dangers of
inaction by capturing the effects of extreme weather and a warming
world.
