Sentences with phrase «confirmed atmospheric concentrations»

Not exact matches

The Solomon Committee report amplifies this conclusion when it confirms that we observe, in any year, only 50 % of the warming to which we have committed the planet by allowing atmospheric concentrations of greenhouse gases to rise to the then current level.

The report confirms that the current atmospheric concentration of carbon dioxide, a critical heat - trapping gas, «exceeds by far the natural range over the last 650,000 years.»

Doesn't this just confirm that anthropogenic emissions are not significant to atmospheric concentrations of C02?

We do not need models to anticipate that significant rises in atmospheric CO2 concentrations harbor the potential to raise temperatures significantly (Fourier, 1824, Arrhenius, 1896), nor that the warming will cause more water to evaporate (confirmed by satellite data), nor that the additional water will further warm the climate, nor that this effect will be partially offset by latent heat release in the troposphere (the «lapse - rate feedback»), nor that greenhouse gas increases will warm the troposphere but cool the stratosphere, while increases in solar intensity will warm both — one can go on and on

We can however confirm the temperature graph does not seem to fully correspond with the rising CO2 concentrations, as both CO2 emissions keep breaking records and the rise of the atmospheric CO2 level seems to be accelerating over recent years.

On Wednesday, scientists at the University of California in San Diego confirmed that April's monthly average atmospheric carbon dioxide concentration breached 410 parts per million for the first time in our history.

«Humans Didn't Exist the Last Time There Was This Much CO2 in the Air» (Eric Holthaus, Grist) «On Wednesday, scientists at the University of California in San Diego confirmed that April's monthly average atmospheric carbon dioxide concentration breached 410 parts per million for the first time in our history...» More...

OCO - 2 observations confirm that the tropical Pacific Ocean played an early and important role in the response of atmospheric CO2 concentrations to the 2015 — 2016 El Niño.

Most importantly, the observations have confirmed that human activities, in particular a 40 % increase in atmospheric carbon dioxide concentrations since the late 19th century, have had a discernible and significant impact on the climate system already.
