Sentence examples for the safe threshold from inspiring English sources

And apparently we're not doing much to stop it: according to Professor Kevin Anderson, one of Britain's leading climate scientists, we've already blown our chances of keeping global warming below the "safe" threshold of 1.5 degrees.

Perhaps even more significantly, though, this will be the last IPCC assessment report before the end of this decade – a decade in which many international organisations say global greenhouse gas emissions need to peak, then start their rapid decline, if we are to have an odds-on chance of staying beneath the "safe" threshold of 2C of warming.

One is the uncomfortable fact that even if, by some miracle, we could immediately cut emissions to zero, due to inertia in the system it would take more than a century for CO2 levels to drop to 350 parts per million, which is considered the safe threshold.

An analysis of the pledges made by countries attending the climate summit in Paris this December has found that the promised reductions as they stand will still exceed the amount of greenhouses gases widely considered to breach of the safe threshold, it says.

Jamilian et al. in 2014 evaluated ion release from NiTi and SS wires in Oral B and Orthokin mouthwashes and noticed that this value was lower than the safe threshold.

The results of our study showed that the release of ions from both wires in Oral B 3D White Luxe, Listerine Advance White, and Oral B was within the safe threshold [14, 26, 27], but the release of nickel from NiTi wires in Listerine was higher than this threshold probably due to the low pH of this solution.

More recently, Fischer et al. [ 40] reported that already after 30 min of HCA at 15°C the oxygen saturation of the frontal cortex as measured on near infrared spectroscopy (NIRS) drops below the relatively safe threshold of 60%, increasing the risk of serious adverse outcomes (p = 0.038).

Mikulewicz et al. in 2012 assessed the release of ions from SS wires in artificial saliva and found that this value reached the maximum safe threshold for nickel ions at 30 days, but the release of chromium was lower than this rate [23].

However, official estimates of fetal doses after the Chernobyl explosion, even in the most contaminated regions of Germany, were < 1 mSv (UNSCEAR 2000), far below the presumed safe threshold.

Further studies are needed in larger multi-institutional prospective trials: 1) to more firmly establish the minimum safe threshold dose for single unit UCB in adult patients treated with RIC, and 2) to identify key parameters for graft selection in the two UCB unit setting that may contribute to enhanced graft vs. malignancy effects confirmed in this prospective single institution study.

The lack of a safe threshold reinforces the realization that to prevent the adverse health effects caused by lead exposure, we must exercise the wisdom to recognize and address the many sources of lead in children's environments.
