A group of scientists in Alaska notices that not only have atmospheric CO2 levels increased at their sampling site but so too have methane levels. What could account for this increase in methane levels

The release of methane from thawed permafrost.

Explanation:

The complete question is

A group of scientists in Alaska notices that not only have atmospheric CO2 levels increased at their sampling site but so too have methane levels. What could account for this increase in methane levels?

- None of the answer options is correct.

- The release of methane from thawed permafrost.

-A decrease in beef production near the researchers' sampling area.

-The melting of permafrost accompanied by the thawing of methane-producing bacteria.

-The failure of rice paddies to be established in Alaska, given its climate.

Permafrost regions like the arctic circle hold a large supply supply of methane in their soils and their seas. Ordinarily, this methane should be gradually released naturally over a long period of time, but the effects of global warming is making these permafrost to thaw at a much faster rate, accelerating the release of methane into the atmosphere. The dark side is that methane is about 80 times more deadly when compared to CO2 in its contribution to the green house effect on earth.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
