Ice on Fire is a 2019 documentary which explores the potential extinction level event caused by arctic methane release, and the newly developed technologies that could reverse global warming by sequestering carbon out of the atmosphere.
Jun 23, 2019 · Ice on Fire explores the many ways we reduce carbon inputs to the atmosphere and, more important, how to "draw" carbon down, bringing CO2 out of the atmosphere and thus paving the way for global temperatures to go down.

Fire is the result of a chemical reaction called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Ordinarily, flames consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. In the usual combustion reaction, a carbon-based fuel burns in air (oxygen). Potentially, fire only con...
However, fire does not actually require oxygen. Yes, the oxidizer most often encounteredisoxygen, but other chemicals also work. For example, burning hydrogen with chlorine as an oxidizer also produces a flame. The product of the reaction is hydrogen chloride (HCl), so the fire consists of hydrogen, chlorine, HCl, light, and heat. Other combination...
In a candle flame or small fire, most of the matter in a flame consists of hot gases. A very hot fire releases enough energy to ionize the gaseous atoms, forming the state of matter called plasma. Examples of flames that contain plasma include those produced by plasma torches and the thermite reaction. The main differences between gases and plasma ...
Fire emits heat and light because the chemical reactionthat produces flames is exothermic. In other words, combustion releases more energy than is needed to ignite or sustain it. In order for combustion to occur and flames to form, three things must be present: fuel, oxygen, and energy (usually in the form of heat). Once energy starts the reaction,...
While all fire produced heat or is exothermic, some fires are cooler than others. So-called cold fire refers to a fire that burns below a temperature of about 400 °C (752 °F). At this temperature, the flame of the fire is invisible, yet the reaction proceeds. While cold fire is fairly uncommon on Earth, scientists have produced it in space. In a mi...

Ice is water that is frozen into a solid state, typically forming at or below temperatures of 0 ° C, 32 ° F, or 273.15 K. It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice.
