You're probably referring to three lakes in Central Africa, Lakes Nyos, Monoun, and Kivu. They periodically undergo what's called "lake overturn," also known scientifically as a limnic eruption. It's a rare set of circumstances: nearby volcanic activity, deep lakes, and an equitorial latitude. The nearby vulcanism means carbon dioxide (CO2) and methane (CH4) bubble up into the lakes' deepest regions. The CO2 dissolves in the water as a result of the increased pressure at that depth (CO2 won't dissolve in water near the surface.) The geographic location of the lakes means there isn't a lot of variance in temperature between seasons, so there's little convection current action going on in the lakes to mix things up. So, the carbon dioxide just accumulates down there, and something like a landslide or small earthquake can shake things up just enough to cause all that CO2 to erupt to the surface. This can cause locally destructive tsunamis, but even more deadly than that, the huge amount of carbon dioxide can blanket whole towns, suffocating people and animals. Carbon dioxide, at 44 grams/mole, is heavier than the mixture of air we breathe, so it doesn't disperse as quickly into the atmosphere. Limnic eruptions in this region have already proven deadly, and efforts are underway to try and "vent" excess CO2 from the lake bottoms before this happens again.

Do cars pollute the air or people?
Both. Cars emit Hydrocarbons + Nitrogen Oxides + Carbon Dioxide + Carbon Monoxide. People emit Methane and Carbon Dioxide.
Does cutting down trees increase the amount of carbon dioxide in the air?
Cutting down trees does increase the amount of carbon dioxide in the air because trees take the carbon monoxide in the air and turn it into oxygen in a process called photosynthesis. Without as many trees then there is going to be more carbon dioxide in the air.
How can you reduce the impact of burning methane on global warming?
We can stop burning methane. Actually burning methane is better than letting it escape into the atmosphere. Methane, when burnt, emits carbon dioxide, a powerful greenhouse gas, but methane, when released into the air, is twenty-one times more dangerous.
What is mars atmosphere like?
very thin and made mostly of carbon dioxide.
The atmospheric concentration of carbon dioxide is regulated by?
Plants play the biggest role in regulating the amount of carbon dioxide in the atmosphere. They do so by using it during photosynthesis and release oxygen.
How many moles of carbon dioxide are produced from the complete combustion of 100.0 grams of methane?
The balanced chemical equation for the combustion of methane is: CH4 + 2O2 -> CO2 + 2H2O From the equation, 1 mole of methane produces 1 mole of carbon dioxide. The molar mass of methane is 16 g/mol, so 100.0 grams of methane is 100.0/16 = 6.25 moles. Therefore, 6.25 moles of carbon dioxide will be produced.
Does the hydrogen on methane go when it becomes carbon dioxide?
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
When methane burns carbon dioxide and water are formed The mass of carbon dioxide plus the mass of water equal the mass of the methane plus the mass of OXYGEN?
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
What commonly contains water ammonia carbon dioxide and methane.?
Water is H2O, ammonia is NH3, carbon dioxide is CO2 and methane is CH4.
What has more energy rich bonds carbon dioxide or methane?
methane
How are the products of combustion different when carbon is burnt rather than methane?
When carbon is burnt, Carbon Dioxide only is produced. When methane is burnt, both carbon dioxide and water are produced.
What volume of carbon dioxide gas is produced after the complete combustion of 1 L of methane gas?
When methane is completely combusted, 1 mole of methane yields 1 mole of carbon dioxide. So, if 1 liter of methane gas is burned, it would produce 1 liter of carbon dioxide gas.
How does cows increase the level of carbon dioxide?
Cows contribute to increased levels of carbon dioxide by producing methane during digestion, a potent greenhouse gas. This methane is released through belching and manure, contributing to the overall greenhouse gas emissions that drive climate change.
Which are the two major greenhouse gases?
Carbon dioxide is emitted by burning fossil fuels (coal, oil and natural gas).Methane is emitted by bad farming practices in cattle and rice farming.
How many times worse is methane compared to carbon dioxide?
Methane is roughly 25 times more potent as a greenhouse gas than carbon dioxide over a 100-year period. This means that, molecule for molecule, methane has a significantly higher global warming potential than carbon dioxide.
What mass of carbon dioxide is produced from the complete combustion of 2.70103 g of methane?
Burning 2 700 g of methane produce 70406 g of carbon dioxide.
When methane is burnt does it produce more carbon dioxide than natural gas?
Yes, burning methane produces carbon dioxide. Methane is the main component of natural gas, so both burning methane and natural gas will release carbon dioxide. However, methane has a higher global warming potential than carbon dioxide, so minimizing methane leaks is also important for reducing overall greenhouse gas emissions.
