The Climate of Conservation in America: 50 Stories in 50 States
-
A state-by-state look at how accelerating climate change is impacting or may impact fish and wildlife across America. The series provides a snapshot of the broad scope of changes and emerging trends we’re just beginning to understand, as well as collaborative efforts to respond across the nation.

THE COST OF INACTION: RECOGNISING THE VALUE AT RISK FROM CLIMATE CHANGE
-
The asset management industry—and thus the wider community of investors of all sizes— is facing the prospect of significant losses from the effects of climate change. Assets can be directly damaged by floods, droughts and severe storms, but portfolios can also be harmed indirectly, through weaker growth and lower asset returns. Climate change is a long-term, probably irreversible problem beset by substantial uncertainty. Crucially, however, climate change is a problem of extreme risk: this means that the average losses to be expected are not the only source of concern; on the contrary, the outliers, the particularly extreme scenarios, may matter most of all.

The global volume and distribution of modern groundwater
-
Groundwater is important for energy and food security, human health and ecosystems. The time since groundwater was recharged—or groundwater age—can be important for diverse geologic processes, such as chemical weathering, ocean eutrophication and climate change. However, measured groundwater ages range from months to millions of years. The global volume and distribution of groundwater less than 50 years old—modern groundwater that is the most recently recharged and also the most vulnerable to global change—are unknown. Here we combine geochemical, geologic, hydrologic and geospatial data sets with numerical simulations of groundwater and analyse tritium ages to show that less than 6% of the groundwater in the uppermost portion of Earth’s landmass is modern. We find that the total groundwater volume in the upper 2 km of continental crust is approximately 22.6 million km3 , of which 0.1–5.0 million km3 is less than 50 years old. Although modern groundwater represents a small percentage of the total groundwater on Earth, the volume of modern groundwater is equivalent to a body of water with a depth of about 3 m spread over the continents. This water resource dwarfs all other components of the active hydrologic cycle.

The Hot Summer of 2010: Redrawing the Temperature Record Map of Europe
-
The summer of 2010 was exceptionally warm in eastern
Europe and large parts of Russia. We provide evidence
that the anomalous 2010 warmth that caused adverse
impacts exceeded the amplitude and spatial extent of the
previous hottest summer of 2003. 'Mega-heatwaves' such
as the 2003 and 2010 events broke the 500-yr long
seasonal temperature records over approximately 50% of
Europe. According to regional multi-model experiments,
the probability of a summer experiencing 'megaheatwaves'
will increase by a factor of 5 to 10 within the
next 40 years. However, the magnitude of the 2010 event
was so extreme that despite this increase, the occurrence
of an analogue over the same region remains fairly
unlikely until the second half of the 21st century.

The links between ecosystem multifunctionality and above- and belowground biodiversity are mediated by climate
-
Plant biodiversity is often correlated with ecosystem functioning in terrestrial ecosystems. However, we know little about the relative and combined effects of above- and belowground biodiversity on multiple ecosystem functions (for example, ecosystem multifunctionality, EMF) or how climate might mediate those relationships. Here we tease apart the effects of biotic and abiotic factors, both above- and belowground, on EMF on the Tibetan Plateau, China. We found that a suite of biotic and abiotic variables account for up to 86% of the variation in EMF, with the combined effects of above- and belowground biodiversity accounting for 45% of the variation in EMF. Our results have two important implications: first, including belowground biodiversity in models can improve the ability to explain and predict EMF. Second, regional-scale variation in climate, and perhaps climate change, can determine, or at least modify, the effects of biodiversity on EMF in natural ecosystems.

Climate Wizard enables technical and non-technical audiences alike to access leading climate change information and visualize the impacts anywhere on Earth. The first generation of this web-based program allows the user to choose a state or country and both assess how climate has changed over time and to project what future changes are predicted to occur in a given area.
