Sentences with phrase «given temperature thresholds»

Not exact matches

The results paint a worrying picture of the future, given that the pledges world nations have submitted under the Paris Agreement are likely still not enough to keep global temperatures within the 2 C threshold envisioned by the accord.

Wet bulb globe temperature is the heat stress metric used by the International Organization for Standardization, and it has well - validated thresholds for when humans can safely work, giving it advantages over alternative metrics such as heat index, said study co-author Chao Li, a hydroclimatology scientist at the University of Victoria in Canada.

This is the difference between countries» pledged commitments to reduce emissions of heat - trapping greenhouse gases after 2020 and scientifically calculated trajectories giving good odds of keeping global warming below the threshold for danger countries pledged to try to avoid in climate talks in 2010 (to «hold the increase in global average temperature below 2 °C above pre-industrial levels»).

«Alternatively, the number of proxies can be lowered through a threshold screening process (Mannet al., 2008) whereby each proxy sequence is correlated with its closest local temperature series and only those proxies whose correlation exceeds a given threshold are retained for model building.

As the «2 °C threshold» came to define the global climate effort, it became common to characterize any given emissions pathway or greenhouse gas budget by its probability of causing a temperature increase of 2 °C or more.

However, it is important to note that there is no unique pathway associated with any given temperature or risk threshold.

While these uncertainties prevent the establishment of a high - confidence, one - to - one linkage between atmospheric greenhouse gas concentrations and global mean temperature increase, probabilistic analyses can assign a subjective probability of exceeding certain temperature thresholds for given emissions scenarios or concentration targets (e.g., Meinshausen, 2005; Harvey, 2007).
