“hottest on record” claims are not meaningful

“These ludicrous headlines by these charlatans often say “hottest on record” or “hottest since records began” without ever saying when that was, even though any records complete and accurate enough to even pretend they are meaningful, by any stretch of the imagination (and these charlatans have quite the imaginations) go back only a few decades, a timescale which climate has been naturally varying over since there was climate, long before man.” click here

Reef islands (e.g. Tuvalu) respond naturally to sea-level changes

Megan E. Tuck, Paul S. Kench, Murray R. Ford, Gerd Masselink. Physical modelling of the response of reef islands to sea-level rise. Geology (2019), https://doi.org/10.1130/G46362.1

“Sea-level rise and increased storminess are expected to destabilize low-lying reef islands formed on coral reef platforms, and increased flooding is expected to render them uninhabitable within the coming decades. Such projections are founded on the assumption that islands are geologically static landforms that will simply drown as sea-level rises. Here, we present evidence from physical model experiments of a reef island that demonstrates islands have the capability to morphodynamically respond to rising sea level through island accretion. Challenging outputs from existing models based on the assumption that islands are geomorphologically inert, results demonstrate that islands not only move laterally on reef platforms, but overwash processes provide a mechanism to build and maintain the freeboard of islands above sea level. Implications of island building are profound, as it will offset existing scenarios of dramatic increases in island flooding. Future predictive models must include the morphodynamic behavior of islands to better resolve flood impacts and future island vulnerability.” click here
