I moved to Merced in 2015 to study for my PhD, and I found a place I could call home. The American Lung Association’s State of the Air report measures three of the major types of pollutants in the San Joaquin Valley: long-term particle matter, short-term particle matter, and ozone. Ozone plays a dual role in our atmosphere.

“If I look at the next 50 years, next hundred years maybe, nobody will be able to set up a telescope that’s powerful enough to resolve surface features,” says Jonathan Jiang , an atmospheric scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who uses Earth as a laboratory to model exoplanets.

Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. Back in 2015, Pollard et al.

Instead, environmentalists were mainly concerned about the ozone layer, nuclear meltdown and chemical industrial pollution, the erosion of biodiversity and population explosion. In June 1979, atmospheric carbon stood at 339ppm, just below the 350ppm level scientists believe to be safe. Today that number is 420ppm and rising.

One good example of the nexus between global warming and local pollution is ground-level ozone. Because of the complexity of atmospheric chemistry, there may be unexpected links between global warming and local pollution, so policies must address both kinds of pollution keeping in mind the latest science on how they are connected.

They do this by analysing the electromagnetic absorption spectra of an exoplanet’s atmosphere as it transits its sun, seeking the presence of gases such as oxygen, methane, water vapour and ozone (a proxy for oxygen). Analogous to technosignatures, these are the signs of life on alien worlds, intelligent or otherwise. Possible signal?

Unlocking UNCLOS as an Instrument of Climate Protection When it comes to addressing the problem of climate change through international law, the global climate treaties—the 1992 United Nations Framework Convention on Climate Change (‘UNFCCC’) and the 2015 Paris Agreement —are undoubtedly the main game in town (see ITLOS advisory opinion, para.
