It has been estimated that the solid earth as a whole contains 730 ppm of carbon, with 2000 ppm in the core and 120 ppm in the combined mantle and crust.

This imbalance, if we want to stabilize climate, means that we must reduce CO2 from 391 ppm, parts per million, back to 350 ppm.

The salt concentration is usually expressed in parts per thousand (permille, ) or parts per million (ppm).

When boron levels in plant tissue exceed 200 ppm, symptoms of boron toxicity are likely to appear.

The evidence also shows that contamination levels are extremely variable, ranging from non detectable amounts to 810,000 ppm.

The last time CO2 was 390 ppm, today's value, sea level was higher by at least 15 meters, 50 feet.

Today, Earth s atmosphere already contains 380 parts per million of CO2. The tipping point could come when we reach 450 ppm.

In our research, we exploit this requirement to specifically target the BRCA1 or BRCA2 defective cancer cells with inhibitors of PARP.

For chemicals, the chemical regulation is usually expressed in parts per million (ppm), or sometimes in milligrams per cubic meter (mg m3).

Ultimately, the culprit was precisely identified as a defective O ring that became too stiff at low temperatures and caused a leak.

Mass production favors the growth of mega banks, so, unlike the misjudgments of lending officers, these behemoths defective models have had disastrous consequences.

As with defective software, they have introduced successive new versions of EMU at a frantic pace only to discover remaining vulnerabilities shortly afterwards.

In other words, even if OECD countries reduce their emissions to zero, they alone could not put the world onto the 450 ppm trajectory.

Rare earth elements change through time in small quantities (ppm, parts per million), so their proportion can be used for geochronology and dating fossils.

Democracy is either defective or missing in Cuba, Mexico, and Nicaragua, and it is threatened by one cause or another in Venezuela and Colombia.

Given that the defective eggs miscarry naturally, more eggs than expected would be needed for the technique possibly posing a risk to the donors.

In my humble opinion, the authoritative sheikh in KSA, who also happens to be the employee of the Saudi king, is using a defective calculator ..

A Japanese propaganda film in 1934 portrayed foreign national flags as incomplete or defective with their designs, while the Japanese flag is perfect in all forms.

One function of the system area is to log defective sectors within the drive essentially telling the hard drive where it can and cannot write data.

The triphosphate serves as a defective substrate for the NS5B protein, which is the viral RNA polymerase, thus acts as an inhibitor of viral RNA synthesis.

Only 155 ppm include deuterium ( or D), a hydrogen isotope with one neutron, and fewer than 20 parts per quintillion include tritium ( or T), which has two.

Nearly all countries neighboring Saudi Arabia already practice one form of electoral participation or another, although most of these nods toward democracy are defective in some way.

A combination of defective growth models, rising longevity, and unanticipated increases in costs (such as health care in America) have caused these longer term liabilities to explode.

When the Sun begins to go nova, everything is on schedule, but most of the spaceships turn out to be defective, and fail en route to Mars.

To avoid the severe risks that would result from a rise in global average temperature of more than 2 C, we must get atmospheric concentrations below 450 ppm.

Consider some numbers from the Stern Review concerning the future benefits of preventing greenhouse gas concentrations from exceeding 550 ppm, as well as the costs of accomplishing this.

Hundreds of people were discovered to have levels greater than 50 ppm of mercury in their hair, the level at which people are likely to experience nerve damage.

The name comes from the number of parts per million of carbon dioxide in the atmosphere that, according to Jim Hansen, perhaps the world s leading climate scientist, we should not exceed if we are to avoid potentially catastrophic climate change. It is a measure of the seriousness of our problem that CO2 is already at 386 ppm, and is rising by two ppm each year.

It suggests that policymakers are playing for longer run sustainable growth and have become warier of policies that, if used persistently, amount to a defective, unsustainable growth model.

Other factors included defective financial regulations, expansionary fiscal policies in countries like the United States, Britain, and Ireland, a lack of appropriate macro prudential regulations, and so on.

And this is to say nothing of the structural faults that continue to impede political progress a defective constitution, censored media, and a partisan security and military establishment.

However, the case for intervention to keep CO2 levels within bounds (say, aiming to stabilize them at about 550 ppm) is sufficiently strong to be insensitive to this dispute.

If we continue with business as usual emissions from activities such as burning fossil fuels and cutting down forests, concentrations could reach 750 ppm by the end of the century.

When the first IPCC report was published in 1990, the concentration of CO2 in the atmosphere had reached 354 parts per million (up from the preindustrial baseline of 280 ppm).

Climate change is not very different from these unsustainable or defective growth patterns. It, too, is essentially a balance sheet problem, based on the stock of CO2 in the atmosphere

And so they also account for development of defective processing in a substantial population of children who are more limited, as a consequence, in their language abilities at an older age.

Still, the problem with genocide is not narrow judging, but that the crime itself is doubly irredeemable it is defective in its definition and troubling in its moral and political effects.
