Ecological and societal disruptions by modern climate change are critically determined by the time frame over which climates shift beyond historical analogues. Here we present a new index of the year when the projected mean climate of a given location moves to a state continuously outside the bounds of historical variability under alternative greenhouse gas emissions scenarios. Using 1860 to 2005 as the historical period, this index has a global mean of 2069 (±18 years s.d.) for near-surface… 
The projected timing of abrupt ecological disruption from climate change
TLDR
Using annual projections of temperature and precipitation across the ranges of more than 30,000 marine and terrestrial species to estimate when species will be exposed to potentially harmful climate conditions reveals that disruption of ecological assemblages as a result of climate change will be abrupt and could start as early as the current decade.
Earth science: The timing of climate change
TLDR
An innovative assessment of climate change calculates the year in which ongoing warming will surpass the limits of historical climate variability, and suggests that the often economically challenged areas in the tropics will face the highest burden of rapidly adapting to the biological effects ofClimate change.
Historical and Projected Climates as a Basis for Climate Change Exposure and Adaptation Potential across the Appalachian Landscape Conservation Cooperative
Global temperatures have risen over the last few decades, and even the most conservative climate models project these trends to continue over the next eighty-five years (IPCC 2013). As climate
Projected timing of perceivable changes in climate extremes for terrestrial and marine ecosystems
TLDR
Simulated TOE patterns suggest unprecedented consecutive dry day occurrence in >50% of 14 terrestrial biomes and 12 marine realms prior to 2100, earlier perceivable changes in climate extremes in countries with lower per capita GDP, and emergence of severe and frequent heat extremes well-before 2030 for the 590 most populous urban centers.
Rapid emergence of climate change in environmental drivers of marine ecosystems
TLDR
It is demonstrated that the exposure of marine ecosystems to climate change-induced stress can be drastically reduced via climate mitigation measures; with mitigation, the proportion of ocean susceptible to multiple drivers within the next 15 years is reduced to 34%.
Projected novelty in the climate envelope of the California Current at multiple spatial-temporal scales
A useful measure of general climate stress is where and when novel habitats emerge. Here we evaluate ‘climate envelope novelty’–a spatial indicator of system-level habitat change–in the California
The timing of unprecedented hydrological drought under climate change
Droughts that exceed the magnitudes of historical variation ranges could occur increasingly frequently under future climate conditions. However, the time of the emergence of unprecedented drought
Climate Exposure of US National Parks in a New Era of Change
TLDR
This work evaluates the climate change exposure of 289 natural resource parks administered by the US National Park Service, and asks which are presently experiencing extreme climates relative to their 1901–2012 historical range of variability (HRV).
Probability of emergence of novel temperature regimes at different levels of cumulative carbon emissions
The United Nations Paris Agreement creates new urgency and importance for understanding the emergence of climate impacts at different levels of cumulative carbon emissions. Using observations and
Dynamical Downscaling of Near‐Term (2026–2035) Climate Variability and Change for the Main Hawaiian Islands
Natural climate variability poses a limit to the confidence in regional climate projections, particularly for the near‐term. Therefore, the next decades are of importance for regional impact studies

Projected distributions of novel and disappearing climates by 2100 AD
TLDR
This work analyzes multimodel ensembles for the A2 and B1 emission scenarios produced for the fourth assessment report of the Intergovernmental Panel on Climate Change with the goal of identifying regions projected to experience high magnitudes of local climate change, development of novel 21st-century climates, and/or the disappearance of extant climates.
Tracking of climatic niche boundaries under recent climate change.
TLDR
A continental assessment of the temporal structure of species responses to recent spatial shifts in climatic conditions is provided, suggesting that the efficiency of species' responses under climate change is likely to be highly idiosyncratic and difficult to predict.
Impacts of climate warming on terrestrial ectotherms across latitude
TLDR
The results show that warming in the tropics, although relatively small in magnitude, is likely to have the most deleterious consequences because tropical insects are relatively sensitive to temperature change and are currently living very close to their optimal temperature, so that warming may even enhance their fitness.
Climate change impacts on marine ecosystems.
In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean
Abrupt Climate Change and Extinction Events in Earth History
TLDR
The analysis suggests that a terrestrially induced climate instability is a viable mechanism for causing rapid environmental change and biotic turnover in earth history, but the relation is not so strong that other sources of variance can be excluded.

A globally coherent fingerprint of climate change impacts across natural systems
TLDR
A diagnostic fingerprint of temporal and spatial ‘sign-switching’ responses uniquely predicted by twentieth century climate trends is defined and generates ‘very high confidence’ (as laid down by the IPCC) that climate change is already affecting living systems.
Abrupt climate change.
TLDR
Policy-makers should consider expanding research into abrupt climate change, improving monitoring systems, and taking actions designed to enhance the adaptability and resilience of ecosystems and economies.
