"What's up with me" in British English means "what's wrong with me". I'll answer both questions. I'm flying from Singapore to London on Friday. During the flight, I'll try to distil the reading I have been doing on atmospheric chemistry during the past weeks. I've ordered a great textbook on Atmospheric Chemistry that awaits me in the UK (more later). I started thinking about the Ozone layer, more on the lines of "why was action successful in that case ('tame Problem') compared to climate change action ('wicked problem')" (to use Hartwell paper language). Atmospheric chemistry became more interesting than the socio-political aspects (though I think the latter are as important as the science). From there to precision isotope ratio measurements by mass spectrometry (of which I know something), then to aerosols and surface chemistry. Isotope ratios are widely used proxies for all manner of things. Chemistry on this scale yet at low concentrations is utterly fascinating, and the reading could be endless.
I'm winding up my lab in Singapore and will return to the UK next year, so we are busy writing papers. To that extent, and also because I don't see climate action primarily as a scientific problem, I'm unlikely to post much outside atmospheric chemistry and isotope measurements.
I'm curious to know how much carbon dioxide I will add to the atmosphere flying to London (I do this every few months). It's the Singapore Airlines A380. British Airways has a voluntary carbon footprint charge (80 GBP if memory serves me). Fortunately, the travelling will end next year. (In part mitigation, I have long stopped going to conferences).
