The amount of methane released by natural gas is the single biggest contributor to global warming.

Methane is a byproduct of natural gas extraction and the methane gas leaks into the atmosphere.

Methanogenicity is measured by a formula: mHg + Hg + CO 2 (1) and is calculated as mH + CO 3 + (mH + H 2 O) + H + CO 4 (2) where: m = mass of gas, H = gas content, CO = carbon dioxide, CO 2 = carbon monoxide.

Methanol, a by-product of gas extraction, is also a major contributor to warming.

There are several sources of methane emissions, but most of them are not in use today.

Here are some examples of the methane emissions produced by natural-gas producers, in order of importance.

The most important sources of natural-Gas emissions are: methane-producing plants: oil refineries and refineries for oil, gas and coal are major sources of emissions of methane.

Some of the major oil refiners and refiners are the U.S. Gulf Coast refineries, the Canadian oil sands refineries in Alberta, the British Columbia oil sands and the Texas oil sands.

Natural gas processing plants: these facilities process natural gas for electricity generation, heating, refrigeration and air conditioning, and for transportation.

Methanes produced from natural gas production are emitted by the plants as well as to the atmosphere from the natural gas being processed.

Methene gas, also known as natural gas condensate, is produced by liquefying natural gas at a higher pressure than natural gas, so that natural gas reacts with other gases in the atmosphere, causing methane to escape.

Methylamine gas, or ethane, is released as methane gas, when ethane is mixed with water and methane is combined with oxygen to produce ethane.

Ethane is the major natural-gases greenhouse gas.

Methyl is another greenhouse gas, produced by combustion of natural gases.

Some chemicals that are produced as by-products of natural energy production also contribute to greenhouse gas emissions.

Methamphetamine and methamphetamine-producing companies: Methamphetamine is a synthetic opioid that has been linked to increased health risks, especially in the United States.

Methadone, an opioid analgesic used to treat opioid dependence, has been shown to increase the risk of suicide, homicide and overdoses.

Methacycline, an anti-inflammatory drug, can also contribute.

In 2013, the European Union banned the sale and use of methadone and methamphetamine and said it will require that methadones and methamphetamine be prescribed only by health care professionals.

Methoxetamine, an anesthetic, can cause convulsions, paralysis and hallucinations in some people.

In 2014, a British study found that methoxetamines, like the synthetic opioid, could increase the chances of having suicidal thoughts.

Methuselah, a synthetic stimulant, has also been linked with addiction and death in people who take it.

In 2017, the U and Australia banned the manufacture and sale of methuselahs and methualles, and introduced stricter testing for the substance.

Methazine, a stimulant and sedative, has become a favorite drug of athletes.

In 2010, it was reported that the use of amphetamines by athletes increased over the past 10 years.

Methotrexate, an antipsychotic medication, has caused side effects, such as delusions, hallucinations and memory loss.

Methylexamphetamine, a highly addictive stimulant used in the manufacture of methamphetamine, has increased in popularity.

Methoxyamphetamine, an illegal drug, has shown to have the same addictive qualities as methamphetamine.

In 2015, the FDA issued new guidelines on the safety of methamphetamine.

Methamphetamines are often used as a recreational drug by young people, which is a problem because it can lead to withdrawal symptoms.

Methamidazole, a commonly prescribed benzodiazepine, has resulted in withdrawal symptoms in people with bipolar disorder, schizophrenia and alcohol abuse, and some people develop psychosis.

Methazolium chloride, a widely used anti-seizure drug, causes sedation and a temporary loss of coordination.

Methosulfur mustard gas, a liquid nitrogen-based substance used to make explosives, can kill and cause severe brain damage.

A chemical that makes up the backbone of the nuclear fuel rods in nuclear power plants releases highly toxic chemicals into the air, including sulfur mustard gas.

The release of these gases from nuclear reactors and power plants contributes to climate change.

The United States Department of Energy has been researching the use and effects of natural compounds in the nuclear power sector.

Natural compounds are compounds that have been produced by nature and are not manufactured or derived from any commercial product.

Some examples of natural molecules that are commonly used in natural gas combustion include: carbon monosulphur compounds (coconut, cocoa, soybean and cotton)
