Agricultural and wetland emissions” from the planet’s tropical areas, not oil and gas activities in the United States, are more than likely responsible for a post-2007 global increase in methane levels, according to the National Oceanic and Atmospheric Administration’s Climate.gov.

As noted in my article four years ago, Japan has a program for producing natural gas from methane hydrates located near its coast, and predicts it will be successful by 2019.
Most people believe that Japan’s objective is highly optimistic, but it does shed light on the efforts currently underway to develop the technology for extracting natural gas from methane hydrates.

Methane emissions influence but do not undermine the environmental case for gas. If the industry can build on the progress to date and deliver a clearer picture on the level of emissions and actions to address them, the arguments for gas displacing coal in power generation and oil products in transport become much stronger.

In their seminal paper on the Vostok Ice Core, Petit et al (1999)  note that CO2 lags temperature during the onset of glaciations by several thousand years but offer no explanation. They also observe that CH4 and CO2 are not perfectly aligned with each other but offer no explanation. The significance of these observations are therefore ignored. At the onset of glaciations temperature drops to glacial values before CO2 begins to fall suggesting that CO2 has little influence on temperature modulation at these times.

The fuel-hungry country has been pursuing the energy source, located at the bottom of oceans and in polar regions, for nearly two decades. China’s minister of land and resources, Jiang Daming, said Thursday that the successful collection of the frozen fuel was “a major breakthrough that may lead to a global energy revolution,” according to state media.
Experts agree that flammable ice could be a game changer for the energy industry, similar to the U.S. shale boom. But they caution that big barriers — both technological and environmental — need to be cleared to build an industry around the frozen fuel, which is also known as gas hydrate.

Good news about climate change is especially rare in the Arctic. But now comes news that increases in one greenhouse gas—methane—lead to the dramatic decline of another. Research off the coast of Norway’s Svalbard archipelago suggests that where methane gas bubbles up from seafloor seeps, surface waters directly above absorb twice as much carbon dioxide (CO2) as surrounding waters. The findings suggest that methane seeps in isolated spots in the Arctic could lessen the impact of climate change.

It is becoming more and more appreciated that a major part of the biologic activity is not going on at the ground surface, but is hidden underneath the soil down to depths of several kilometres in an environment coined the « deep biosphere ». Studies of life-forms in this energy-poor system have implications for the origin of life on our planet and for how life may have evolved on other planets, where hostile conditions may have inhibited colonization of the surface environment. The knowledge about ancient life in this environment deep under our feet is extremely scarce.

Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes Island, Canadian High Arctic, discovered an astounding number of methane seep mounds in Cretaceous age sediments.

Methane is about 25 times stronger than carbon dioxide, with some estimates as high as 33 times stronger due to its effects when it is in the atmosphere.
Because of methane’s global warming potential, identifying the sources and « sinks » or storehouses of this greenhouse gas is critical for measuring and understanding its implications across ecosystems.
