    Antarctica Is Going Green, And Not In A Good Way

    New research indicates the "greenhouse effect" that helps drive climate change could be greening even the most inhospitable end of the Earth. A research team has confirmed that plant life on Antarctica has been growing and spreading rapidly across the continent that we tend to think of as being one big chunk of ice at the bottom of the world.

    Arctic stronghold of world’s seeds flooded after permafrost melts | Guardian

    On the Norwegian island of Spitsbergen the Global Seed Vault was built in underground tunnels in permafrost to provide “failsafe” protection against “the challenge of natural or man-made disasters”. But soaring temperatures in the Arctic at the end of the world’s hottest ever recorded year led to melting and heavy rain produced by the extraordinary temperatures over the winter, which sent meltwater gushing into the entrance tunnel. Fortunately, the meltwater did not reach the vault itself, the ice has been hacked out, and the precious seeds remain safe for now at the required storage temperature of -18C.

    Stop hoping we can fix climate change by pulling carbon out of the air, scientists warn | Washington Post

    Two studies, here and here, are showing that it is impractical to rely on pulling CO2 out of the air by planting trees to meet the max 2C temperature increase target set by the Paris agreement. To plant enough trees to meet the goal would require either that many of the trees be planted in fertile areas, which would unacceptably take land away from food production, or the trees could be planted in less less-productive soils, which would require large amounts of non-renewable resources to sustain the necessary growth. However, biomass energy and carbon capture can be an essential tool, along with the essential self-limiting of burning of fossil fuels.

    What happens to Earth if the US exits the climate deal? | Washington Post

    With the US producing 1/5 of the world's anthropogenic CO2, a number of groups have made estimates of how much higher temperatures will increase if the US pulls out of the Paris climate agreements. One group estimates an increase of 1/2F (0.3C) above what is expected. Another group say that number is too high, because the US is burning more low-carbon natural gas rather than high-carbon coal. Yet another group calculates that the number could be low, because if the US pulls out other countries are more apt to leave the agreements as well.

    No matter what the US does it is likely Earth's temperatures will exceed the 2C target set by the Paris agreements, with the preferred goal of 1.5C being a total pipe dream.

    Great Barrier Reef 2050 plan no longer achievable due to climate change, experts say | The Guardian

    Surveys show that 29% of corals died in 2016, greater than the figure of 22% projected in mid-2016. The worst-hit area was near Port Douglas, where 70% of shallow water corals died, but there was a recovery of corals in the south of the reef.

    The federal and Queensland government’s Reef 2050 Long Term Sustainability Plan, which was released in 2015, has as its central vision to “ensure the Great Barrier Reef continues to improve on its outstanding universal values”. The plan was created to satisfy the Unesco World Heritage Centre, which was considering adding the Great Barrier Reef to its list of world heritage sites in danger, as it was thought its condition could be improved. But now two experts from government science agencies said improving the natural heritage values of the reef was no longer possible. The experts said the plan should be revised to aim for something more achievable, suggesting it could aim to “maintain the ecological function” of the reef, while accepting that its overall health would inevitably decline.

    Stony corals more resistant to climate change than thought | Science Daily

    In a study published in Science, researchers have discovered that stony corals (which make "rock" reefs) use acid-rich proteins, rather than physical and chemical processes as was previously thought, to build their rock-hard skeletons made of calcium carbonate minerals. This suggests that at least the studied coral Stylophora pistillate will still be be able to make rock as the oceans' pH changes from 8.2 to the expected 7.8 during the next century. Nevertheless, increased water temperatures, which causes coral bleaching, are still a big concern.

    Scientists keep upping their projections for how much the oceans will rise this century | Washington Post

    The new Snow, Water, Ice and Permafrost in the Arctic report presents minimum estimates for global sea level rise by the end of the century, but not a maximum. This reflects the fact that scientists keep uncovering new insights that force them to increase their sea level estimates further. The assessment found that under a relatively moderate global warming scenario — one that slightly exceeds the temperature targets contained in the Paris climate agreement — seas could be expected to rise “at least” 52 centimeters, or 1.7 feet, by the year 2100. Under a more extreme, “business as usual” warming scenario, meanwhile, the minimum rise would be 74 centimeters, or 2.4 feet. The report bluntly contrasts its sea level findings with a previous 2013 report from the U.N. Intergovernmental Panel on Climate Change, which had put the “likely” low end sea level rise number for these two scenarios at 32 centimeters (about 1 foot) and 45 centimeters (1.5 feet) for the period between 2081 and 2100.

    A climate chain reaction: Major Greenland melting could devastate crops in Africa | Washington Post

    A new study, published in the Proceedings of the National Academy of Sciences, suggests that the run-off from increasing Greenland ice melt has the potential to slow down the Atlantic Meridional Overturning Circulation -- the major water and heat conveyor in the Atlantic Ocean. This, in turn, would likely turn dry out Africa’s Sahel, a narrow region of land stretching from Mauritania in the west to Sudan in the east. Tens of millions of people could be forced to migrate from the area due to agriculture failure.

    Scientists stunned by Antarctic rainfall and a melt area bigger than Texas | Washington Post

    In the Antarctic summer of 2016, the surface of the Ross Ice Shelf, the largest floating ice platform on Earth, developed a sheet of meltwater that lasted for as long as 15 days in some places. The total area affected by melt was 300,000 square miles, or larger than the state of Texas. That’s bad news because surface melting could work hand in hand with an already documented trend of ocean-driven melting to compromise West Antarctica, which contains over 10 feet of potential sea level rise. That makes them potentially much more unstable.”

    Researchers from Ohio State University published their report in Nature Communications.
