Writing as background for their study, Duvat et al. (2017) state that “it has commonly been considered that atoll reef islands would disappear under climate change, as a result of sea-level rise and induced accelerating shoreline erosion,” citing the works of Connell (2003), Dickinson (2009) and McAdam (2010). This perception is based on model predictions, which have been hyped all over the globe, especially among politicians and the media, some of whom demand reparations for small island States who they fear will be forced to abandon their islands within decades.
But how much faith should one place in such projections and concerns?
According to Duvat et al., not that much … (…)

Have you been keeping an eye on Sol lately? One of the top astronomy stories for 2018 may be what’s not happening, and how inactive our host star has become.
The strange tale of Solar Cycle #24 is ending with an expected whimper: as of May 8th, the Earthward face of the Sun had been spotless for 73 out of 128 days thus far for 2018, or more than 57% of the time. This wasn’t entirely unexpected, as the solar minimum between solar cycle #23 and #24 saw 260 spotless days in 2009 – the most recorded in a single year since 1913.
Cycle #24 got off to a late and sputtering start, and though it produced some whopper sunspots reminiscent of the Sol we knew and loved on 20th century cycles past, it was a chronic under-performer overall. Mid-2018 may see the end of cycle #24 and the start of Cycle #25… or will it?
