**Fate of Mountain Glaciers in the Anthropocene, A Report by the Working Group Commissioned by the Pontifical Academy of Sciences **
Anthropocene: Aggressive exploitation of fossil fuels and other natural
resources has damaged the air we breathe, the water we drink, and the land we inhabit.
To give one example, some 1000 billion tons of carbon dioxide and other climatically
important “greenhouse” gases have been pumped into the atmosphere. As a result,
the concentration of carbon dioxide in the air now exceeds the highest levels of the
last 800,000 years. The climatic and ecological impacts of this human interference
with the Earth System are expected to last for many millennia, warranting a new name,
The Anthropocene, for the new “man-made” geologic epoch we are living in. p.3
An expert group of scientists met under the auspices of the Pontifical Academy
of Sciences at the Casina Pio IV in the Vatican from 2 to 4 April 2011 to discuss the
fate of mountain glaciers in the Anthropocene and consider the responses required
to stabilize the climate change affecting them. This group’s consensus statement is a
warning to humanity and a call for fast action—to mitigate global and regional warming,
to protect mountain glaciers and other vulnerable ecosystems, to assess national
and local climate risks, and to prepare to adapt to those climate impacts that cannot be
mitigated. The group also notes that another major anthropogenic risk to the climate
system is from the threat of nuclear war, which can be lessened by rapid and large
reductions in global nuclear arsenals. p 7
Because of the time lag between mitigation action and climate response, vulnerable
ecosystems and populations will face significant climate impacts and possibly unacceptable risks even with ultimately successful mitigation. Therefore, in addition to
mitigation, adaptation must also start now and be pursued aggressively. p 13

A comprehensive approach for reducing anthropogenic climate impacts including risk
of abrupt climate changes*
Successfully addressing long-term climate change requires fast and aggressive
cuts in CO2 emissions, but that is not enough. In the face of uneven
regional warming and increasing climate impacts that are already occurring
and that may be accelerating, fast and aggressive cuts in SLCFs also are essential p. 8
Faced with serious and largely irreversible changes to large components
of the Earth’s climate system, a comprehensive climate policy can benefit
from considering all sources of warming and all mitigation options. The
scale and speed of climate change impacts requires comprehensive fast-action
mitigation strategies, including strategies to reduce both CO2 and non-
CO2 climate forcers, and to protect and expand existing and new carbon
sinks. p 12
