A global overview of drought and heat-induced tree mortality reveals emerging climate change risks for forests
Craig D. Allen,Alison K. Macalady,Haroun Chenchouni,Dominique Bachelet,Nate G. McDowell,Michel Vennetier,Thomas Kitzberger,Andreas Rigling,David D. Breshears,Edward H. Hogg,Patrick Gonzalez,Rod Fensham,Zhen Zhang,Jorge Castro,N.A. Demidova,Jong Hwan Lim,Gillian Allard,Steven W. Running,Akkin Semerci,Neil S. Cobb +19 more
TL;DR: In this paper, the authors present the first global assessment of recent tree mortality attributed to drought and heat stress and identify key information gaps and scientific uncertainties that currently hinder our ability to predict tree mortality in response to climate change and emphasizes the need for a globally coordinated observation system.
Journal ArticleDOI
A statistical explanation of MaxEnt for ecologists
TL;DR: A new statistical explanation of MaxEnt is described, showing that the model minimizes the relative entropy between two probability densities defined in covariate space, which is likely to be a more accessible way to understand the model than previous ones that rely on machine learning concepts.
Journal ArticleDOI
Social Capital, Collective Action, and Adaptation to Climate Change
TL;DR: The authors argue that societies have inherent capacities to adapt to climate change, but these capacities are bound up in their ability to act collectively, and they argue that this capacity is limited by the nature of the agents of change, states, markets and civil society.
Journal ArticleDOI
A blueprint for blue carbon: toward an improved understanding of the role of vegetated coastal habitats in sequestering CO2
Elizabeth Mcleod,Gail L. Chmura,Steven Bouillon,Rodney Salm,Mats Björk,Carlos M. Duarte,Carlos M. Duarte,Catherine E. Lovelock,William H. Schlesinger,Brian R. Silliman +9 more
TL;DR: In this paper, the authors identify key areas of uncertainty and specific actions needed to address them and identify the value of mangrove forests, seagrass beds, and salt marshes in sequestering carbon dioxide.
Journal ArticleDOI
A new scenario framework for climate change research: the concept of shared socioeconomic pathways
Brian C. O'Neill,Elmar Kriegler,Keywan Riahi,Kristie L. Ebi,Stephane Hallegatte,Timothy R. Carter,Ritu Mathur,Detlef P. van Vuuren,Detlef P. van Vuuren +8 more
TL;DR: A conceptual framework for how to define and develop a set of Shared Socioeconomic Pathways (SSPs) for use within the scenario framework for climate change research is proposed.

Journal ArticleDOI
Influence of variations in extratropical wintertime teleconnections on northern hemisphere temperature
TL;DR: The authors used multivariate linear regression to show that nearly all the cooling in the northwest Atlantic and the warming across Europe and downstream over Eurasia since the mid-1970s results from the changes in the North Atlantic Oscillation (NAO), and the NAO accounts for 31% of the hemispheric interannual variance over the past 60 winters.
Journal ArticleDOI
Oceanic forcing of Sahel rainfall on interannual to interdecadal time scales.
TL;DR: Evidence is presented to suggest that variability of rainfall in the Sahel results from the response of the African summer monsoon to oceanic forcing, amplified by land-atmosphere interaction.
Journal ArticleDOI
Extracting a Climate Signal from 169 Glacier Records
TL;DR: A temperature history for different parts of the world from 169 glacier length records is constructed using a first-order theory of glacier dynamics, which related changes in glacier length to changes in temperature.
Journal ArticleDOI
Climate over past millennia
Philip Jones,Michael E. Mann +1 more
TL;DR: This paper reviewed evidence for climate change over the past several millennia from instrumental and high-resolution climate "proxy" data sources and climate modeling studies and concluded that late 20th century warmth is unprecedented at hemispheric and, likely, global scales.
Journal ArticleDOI
Weakening of tropical Pacific atmospheric circulation due to anthropogenic forcing
Gabriel A. Vecchi,Brian J. Soden,Andrew T. Wittenberg,Isaac M. Held,Ants Leetmaa,Matthew Harrison +5 more
TL;DR: Observed Indo-Pacific sea level pressure reveals a weakening of the Walker circulation, and the climate model indicates that the weakened surface winds have altered the thermal structure and circulation of the tropical Pacific Ocean.
