Sentences with phrase «atmospheric concentrations»

Scientific predictions of the impacts of increasing atmospheric concentrations of greenhouse gases from fossil fuels and deforestation match observed changes.

However, the rise in atmospheric concentration of CO2 driving the modern warming is NOT coming from the oceans, but from the human burning of fossil fuels.

Both of these trends are consistent with the influence of increasing atmospheric concentrations of greenhouse gases.

However, for at least the past three centuries, rising energy production globally has been matched by rising atmospheric concentrations of carbon dioxide.

First, we need to realize that to stabilize atmospheric concentrations of greenhouse gases, our current emissions have to tend towards zero.

Nor are the commitments that have been made even remotely consistent with stabilizing atmospheric concentrations at anywhere close to 2 degrees Celsius, much less 1.5.

About half of this near - term warming represents a «commitment» to future climate change arising from the inertia of the climate system response to current atmospheric concentrations of greenhouse gases.

It is misleading to refer to CO2 emissions that do not increase atmospheric concentration by 100 percent of their value as «missing».

Why are the global atmospheric concentrations of methane leveling off?

As a result, the average atmospheric concentration can be monitored well by existing ground stations (about 160 worldwide).

These emissions are run through a carbon - cycle model (which may be simple or complex) to produce atmospheric concentrations over time.

Recent evidence suggests that decreasing atmospheric concentrations of carbon dioxide during this period may have initiated a steady and irreversible cooling trend over the next few million years.

It also means that scientists and other experts are going to have to monitor measures other than just atmospheric concentration of greenhouse gases to catch catastrophic climate change developing.

However, albedo modification would only temporarily mask the warming effect of greenhouse gases and would not address atmospheric concentrations of CO2 or related impacts such as ocean acidification.

Scientists can determine ancient atmospheric concentrations by measuring CO2 and methane levels in tiny air bubbles trapped in such ice, formed when the ice fell to the earth as snow.

The first confirmed atmospheric concentrations of carbon dioxide are at their highest levels in at least 800,000 years and possibly 3 million to 5 million years.

The dangers of climate change are rising as the burning of fossil fuels and deforestation worldwide boost atmospheric concentrations of carbon dioxide.

It's not like carbon dioxide is a poison at current atmospheric concentrations.

Global atmospheric concentrations of methane are rising — along with scientific scrutiny of this potent greenhouse gas.

Yet understanding how delay makes achieving the goals of preventing dangerous climate change extraordinarily more challenging also requires some knowledge about how increasing atmospheric concentrations affect global emissions reductions pathways options.

A central conclusion of the report is that it is more effective to assess climate stabilization goals using global mean temperature change as a primary metric, rather than atmospheric concentration levels.

There is no distinction between «old» and «new» CO2, just atmospheric concentration.

At that time they did not have good data for atmospheric concentrations prior to 1958, hence their hindcast back to 1900 was wrong, but despite this, their projection for changes forward to 2000 were remarkably good.

Parkes and his colleagues ran simulations of a «very mild form» of climate change where carbon emissions rise by 1 % a year until atmospheric concentrations reach double pre-industrial levels (560 parts per million, ppm).

The first couple of lines on your web page read «Carbon dioxide is NOT a Pollutant» and «The increase in atmospheric concentration from 280 ppm in 1750 to 384 ppm at end 2007 is trivial».

For example, a change in carbon storage in ecosystems that reduces atmospheric concentrations causes changes in climate forcing and ocean acidification, which in turn affect myriad other environmental attributes, including precipitation patterns, with effects on agricultural production, the probability and severity of flooding, and the health of marine resources, among others.
