Highlights

• The necessity of expanding satellite technology to monitor methane emissions more accurately and comprehensively.
• The importance of differentiating between natural and man-made sources of methane to better target reduction efforts.
• The critical role of high-resolution data in enabling precise identification of methane leak sources.
• The growing collaboration between public efforts like MethaneSAT and private endeavors like GHGSat in the fight against climate change.
• The ongoing development and future potential of methane monitoring technology to cover hard-to-track natural emissions.
• The vital need for more empirical data to support global pledges for emission reductions and regulatory measures.

The addition of MethaneSAT to the armada of methane-detecting satellites marks a significant milestone in efforts to understand and mitigate the effects of methane on climate change. This new satellite, designed to monitor methane emissions, joins a fleet that serves as Earth's eyes, identifying methane sources with increasing precision. Despite the humor that their sheer number might offset global warming by shadowing sunlight, scientists argue for the necessity of such tools in comprehensively mapping methane emissions, which come from both natural and anthropogenic sources.

Since the inception of methane monitoring from space with Japan's GOSAT in 2009, the field has evolved, now encompassing satellites like MethaneSAT by the Environmental Defense Fund and GHGSat by a private company. These initiatives underscore the transformation from ground-based observation to a more geographically diverse understanding of methane sources. Methane's potent warming effect despite its relatively short atmospheric life underscores the urgency of addressing its emissions swiftly. The technological advancements in satellite monitoring open doors to unprecedented granularity in data, enabling the attribution of emissions down to specific facilities.

The future of methane monitoring is bright with anticipated advancements aiming to bridge current gaps in coverage and resolution. While present efforts focus largely on anthropogenic sources, especially in the oil and gas sectors, there's a push towards understanding natural emissions better. The collaboration between various sectors, including governmental agencies, nonprofit organizations, and private companies, signifies a holistic approach towards tackling methane emissions. The role of technology in environmental protection is thus underscored, with methane monitoring from space playing a pivotal role in global climate change mitigation efforts.
