*White Christmas Forecast For Some From Wyoming Through Maine 
<https://www.npr.org/sections/thetwo-way/2017/12/23/573175529/white-christmas-forecast-for-some-from-wyoming-through-maine>*
  for millions of people along the projected path of a system forming 
Saturday in the Great Plains that is forecast to become a nor'easter in 
New England by Monday, a white Christmas is looking more like a reality.
"We are going to have a decent swath of snow," meteorologist Marc 
Chenard with the National Weather Service tells NPR.
Beginning Saturday, a couple of inches are expected in Wyoming, Colorado 
and Nebraska.
As the system shifts eastward by Christmas Eve, it is forecast to 
blanket parts of the Midwest, including Illinois, Michigan and Indiana.
Chicago should get 2 to 3 inches; Kansas City, Mo., 1 to 2 inches, 
Chenard says.

**Climate Change Likely To Increase Volcanic Eruptions, Scientists Say 
<https://www.npr.org/sections/thetwo-way/2017/12/22/572795936/climate-change-likely-to-increase-volcanic-eruptions-scientists-say>*
A warming planet due to human-induced climate change is likely to 
contribute to an increase in volcanic activity, according to a recent 
study in the journal Geology.
While a relationship between climate and volcanism might seem 
counterintuitive, it turns out that pressure exerted by thick glaciers 
on the Earth's crust - what geologists call "surface loading" — has an 
impact on the flow of magma below the surface.
The correlation affects "magma flow and the voids and gaps in the Earth 
where magma flows to the surface as well as how much magma the crust can 
actually hold," study lead author Graeme T. Swindles, an associate 
professor of Earth system dynamics at the University of Leeds, wrote in 
an email to Scientific American...
Swindles says his team found about a 600-year lag between advancing 
glaciers and diminished volcanic activity. "That's because it takes a 
long time to grow ice masses," he told the magazine.
In reverse, the team found that as the climate warmed and glaciers 
melted, there were more and bigger eruptions.
"After glaciers are removed the surface pressure decreases, and the 
magmas more easily propagate to the surface and thus erupt," Swindles says.
There was also a lag between retreating glaciers and increased volcanic 
activity, but it was shorter, the team found — although the study 
cautions there could be other climate-related factors that contributed 
to the compressed lag time.

*Partnership will use robotic network to explore Antarctic ice shelves 
<https://www.washington.edu/news/2017/12/18/partnership-will-use-robotic-network-to-explore-antarctic-ice-shelves/>*
One of the biggest unknowns for the future of Earth's climate is 
Antarctica, where the West Antarctic Ice Sheet holds so much ice that if 
it collapsed could bring several feet of rising seas.
A new partnership between the University of Washington's College of the 
Environment, the UW Applied Physics Laboratory and Paul G. Allen 
Philanthropies will use a robotic network to observe the conditions 
beneath a floating Antarctic ice shelf...
Ice shelves act as buttresses that restrain the flow of inland ice into 
the sea, which under a warmer climate could trigger many feet of global 
sea level rise, on a timeline that is largely unknown. Observations in 
the water-filled caves under ice shelves could help explain how warmer 
seawater interacts with the glacier's underbelly...
the seafloor," Christianson said. "If we can do that, we'll be able to 
collect tons of new data. We often don't even know what the topography 
of the seafloor is like beneath the shelf, which affects water flow, 
temperature and other factors that control the melting rate."...

[AGWA Water]
Water infrastructure <www.alliance4water.org> is expensive and 
long-lived. How do we design and plan for resilience if we can't see 
what the future holds in terms of climate or other relevant drivers? The 
World Bank's Decision Tree Framework 
<https://openknowledge.worldbank.org/handle/10986/22544> is a new tool - 
one of a suite of "bottom-up approaches <http://agwaguide.org/>" - that 
embraces uncertainty. It allows users to assess and address long-term 
climatic and non-climatic risks. In the latest episode of the 
/#ClimateReady Podcast <http://agwaguide.org/library/climateready/>/, 
Dr. Patrick Ray 
<http://ceas.uc.edu/chemical-environmental-engineering/Ray_lab.html> 
explains how the process works, where it's being implemented, and how 
institutions can incorporate the DTF into their water management 
projects. Take a listen and make sure to subscribe on iTunes

*This Day in Climate History December 24, 1988

-  from D.R. Tucker*
December 24, 1988: TIME Magazine names "Endangered Earth" its "Planet
of the Year" for 1988, citing in part rising concerns over global
warming.

    TIME MAGAZINE PICKS EARTH IN LIEU OF MAN OF THE YEAR
      In the cover article of its Jan. 2 issue, released Saturday, Time
    warned of a series of impending environmental catastrophes:
    -Pollution-caused warming of the atmosphere, known as the
    "greenhouse effect," threatening weather changes that could flood
    coastlines and render large areas of the planet infertile and
    uninhabitable.
    -Toxic and radioactive wastes and dumped garbage that could poison
    drinking water and despoil the land.
    -Chemical pollution that is depleting the atmosphere's protective
    ozone layer.
    -Clearing of tropical rain forests, driving thousands of species to
    extinction.
