Coal, oil, and gas are responsible for much more atmospheric methane, the super-potent warming gas, than previously known.

It's the workhorse of any kitchen, almost taken for granted, so more often than not, skipping the stove on cleaning day isn't surprising at all.

Global levels of the potent greenhouse gas methane rose to a record high for a second consecutive year in 2021, according to data released by NOAA on Thursday, hitting the highest levels since scientists began measuring these emissions nearly four decades ago.

You may have noticed that different substances have widely varying boiling points. Ethanol, for example, boils at a lower temperature than water. Propane is a hydrocarbon and a gas, while gasoline, a mixture of hydrocarbons, is a liquid at the same temperature. You can rationalize or explain these differences by thinking about the structure of each molecule. In the process, you'll gain some new insights into everyday chemistry.
