Sentences with phrase «emit at current rates»

Since even the IPCC estimates this constant at ~ 8 years (corresponding to a half - life of 5 years), this means that if humankind had been emitting at the current rate of 8GTC / yr for the last century we still would only be responsible for ~ 30ppm of the 100ppm increase over that time.

Not exact matches

This is partly due to the current atmosphere containing much less CO2 — approximately 400 ppm (parts per million)-- compared to before the PETM, where the concentration was about 1,000 ppm and partly because we emit carbon into the atmosphere at a much faster rate than during the PETM.

«Dramatic rises in sea level are almost inevitable if we continue to emit greenhouse gases at the current rate.»

If demand for meat continues to increase at its current rate, by 2050 we'll be eating two thirds more meat than we do today — which would also mean emitting two thirds more greenhouse gases from meat production.

Just over half that amount has already been emitted since the beginning of the Industrial Revolution, and at current rates of energy consumption, the trillionth ton will be released around 2040, according to calculations by Myles R. Allen, a scientist at the University of Oxford and one of the authors of the new report.

You could argue the paleo isn't refined enough for the current period, but there is nothing to suggest that the current warming will not continue at its current rate as long as we continue to emit.

The Intergovernmental Panel on Climate Change projects that if the world continues to emit greenhouse gasses at its current rate, carbon dioxide could double somewhere around the middle of the century.

Their unwillingness to take immediate action is intellectually and morally bankrupt because unless carbon emissions are stopped very soon (remember that the damage is cumulative so continuing to emit at current of even reduced rates still causes additional damage hundreds if not thousands of years into the future.)

therefore: ``... If we continue to emit greenhouse gases at our current rate, we risk doubling that atmospheric CO2 level in roughly 2050.»

About 24 years — that's how long it will take for humans to burn enough fossil fuels and emit enough carbon (at current and projected rates) to use up that «carbon budget.»

We will get to about 580ppm by 2100 simply by continuing to emit CO2 at our current rate (about 2ppm p.a.) with our current population and level of GDP.

At the current carbon emissions rate of more than 10 billion tons each year and growing at around 2 percent, humans will have emitted a trillion tons of carbon by 204At the current carbon emissions rate of more than 10 billion tons each year and growing at around 2 percent, humans will have emitted a trillion tons of carbon by 204at around 2 percent, humans will have emitted a trillion tons of carbon by 2041.

If humans continue to emit greenhouse gases at current rates, the remaining carbon budget to reduce the risk of exceeding the internationally - agreed 2 °C temperature rise target will be exhausted in around 20 years.

If, for instance, the United States and India are required to reduce ghg emissions by the same percentage amount, for instance 90 %, then the US per capita emissions of approximately 20 tons CO2 per capita would allow US citizens to emit CO2 at the rate of 2 tons per capita while the current India per capita emissions of approximately 1.8 tons per capita would mean that the Indian citizens could emit only at the rate 0.18 tons per capita even though India needs to dramatically increase its energy use to assure that hundreds of millions of people economically rise out of grinding poverty and India has comparatively done little to cause the existing problem.

That means emitting in total no more than about 800 billion tons of CO2 from all sources — or less than 20 years worth at current rates.

Since the world is now emitting carbon dioxide equivalent emissions at approximately 10 metric gigatons per year, the world will run out of emissions under the budget in approximately 25 years at current emissions rates.

In any case, again, figure 3 shows that if we stop all emissions now (and yes, Jim, that means completely stop emitting any more CO2, not just stabilize the rate we are emitting at now, unless I'm missing something), with a climate sensitivity of 3 degrees C we will see atmospheric CO2 levels remain at current high levels for centuries.

To radiate all that energy away at the current rate the earth emits would be: Current emitted power = 1.22 * 10 ^ 17W 7.62 * 10 ^ 23J / 1.22 * 10 ^ 17W = 6.25 million seconds =current rate the earth emits would be: Current emitted power = 1.22 * 10 ^ 17W 7.62 * 10 ^ 23J / 1.22 * 10 ^ 17W = 6.25 million seconds =Current emitted power = 1.22 * 10 ^ 17W 7.62 * 10 ^ 23J / 1.22 * 10 ^ 17W = 6.25 million seconds = 72days

Assuming China's emissions continue to rise at the current rate of about three per cent a year for the next sixteen years, the country will be emitting around 16 gigatonnes of carbon dioxide equivalent a year by 2030, according to thinktank Climate Action Tracker.
