The children's climate crusade
Many studies have sought to constrain climate projections based on recent observations.
Until recently, these constraints had limited impact, and projected warming ranges
were driven primarily by model outputs. Here, we use the newest climate model ...
The COVID-19 (coronavirus disease 2019) pandemic has resulted in a marked slowdown
in greenhouse gas and aerosol emissions. Although the resulting emission reductions
will continue to evolve, this will presumably be temporary. Here, we provide estimates
...
Studies have documented climate change–induced shifts in species distributions but
uncertainties associated with data and methods are typically unexplored. We reviewed
240 reports of climate-related species-range shifts and classified them based on three
...
Strategies for 21st-century environmental management and conservation under global
change require a strong understanding of the biological mechanisms that mediate responses
to climate- and human-driven change to successfully mitigate range contractions, ...
Anthropogenic climate change is expected to affect global river flow. Here, we analyze
time series of low, mean, and high river flows from 7250 observatories around the
world covering the years 1971 to 2010. We identify spatially complex trend patterns,
...
Unprecedented heatwave-drought concurrences in the past two decades have been reported
over inner East Asia. Tree-ring–based reconstructions of heatwaves and soil moisture
for the past 260 years reveal an abrupt shift to hotter and drier climate over this
...
Harvesting floodwaters to recharge depleted groundwater aquifers can simultaneously
reduce flood and drought risks and enhance groundwater sustainability. However, deployment
of this multibeneficial adaptation option is fundamentally constrained by how ...
Human societies will transform to address climate change and other stressors. How
they choose to transform will depend on what societal values they prioritize. Managed
retreat can play a powerful role in expanding the range of possible futures that ...
The impacts of climate change and the socioecological challenges they present are
ubiquitous and increasingly severe. Practical efforts to operationalize climate-responsive
design and management in the global network of marine protected areas (MPAs) are ...
Perspective
Surprises for climate stability
While the Atlantic Meridional Overturning Circulation (AMOC) is projected to slow
down under anthropogenic warming, the exact role of the AMOC in future climate change
has not been fully quantified. Here, we present a method to stabilize the AMOC ...
For the current generation of earth system models participating in the Coupled Model
Intercomparison Project Phase 6 (CMIP6), the range of equilibrium climate sensitivity
(ECS, a hypothetical value of global warming at equilibrium for a doubling of CO2) ...
New Guinea is the most biologically and linguistically diverse tropical island on
Earth, yet the potential impacts of climate change on its biocultural heritage remain
unknown. Analyzing 2353 endemic plant species distributions, we find that 63% of ...
As climate change intensifies, civil society is increasingly calling for transformative
adaptation that redresses drivers of climate vulnerability. We review trends in how
US federal government, private industry, and civil society are planning for climate
