(CNN)A tsunami has hit Tonga’s largest island, Tongatapu, and reportedly sent waves flooding into the capital after an underwater volcano in the South Pacific exploded in a violent eruption on Saturday, sending a cloud of ash and gas steam into the air.Satellite imagery shows a massive ash cloud and shockwaves spreading from the eruption. The…
Flood basalts and mass extinctions – ancient hyperthermals as analogs for anthropogenic climate change. Oceanic Anoxic Event (OAE) and mass extinctions are considered to be hyperthermals – usually associated with flood basalt eruptions.[2] Phases of rapid global warming, known collectively as hyperthermals.[1] Flood basalts are a subset of large igneous provinces (LIPs), the terms flood basalt…

With news breaking that Alaska just had its warmest March to May on record with a statewide average temperature of 32.6°F, 8.6°F above the long-term average – the previous warmest spring in Alaska was in 2016, one must ask how this performs in relation to seismicity. First we learn that according to the University of…

Abstract The global warming potential of methane (CH4) is about 30 times stronger than that of carbon dioxide (CO2) over a century timescale. Methane emission is hypothesized…
We report the discovery of a large impact crater beneath Hiawatha Glacier in northwest Greenland. From airborne radar surveys, we identify a 31-kilometer-wide, circular bedrock depression beneath up to a kilometer of ice http://advances.sciencemag.org/content/4/11/eaar8173 Hiawatha Glacier https://en.wikipedia.org/wiki/Hiawatha_Glacier Sources Discovering a massive meteorite crater https://www.youtube.com/watch?v=hQ9maLsIcts Massive crater under Greenland’s ice points to climate-altering impact in the…
Climate unknowns include the rate of sea level rise, ozone loss, how the Gulf Stream will react and what it possibly means, the Earth’s response, and the potential for extra methane release from methane clathrates, stored at continental margins. There are many more climate unknowns, for example elaborated in this article https://thinkprogress.org/what-are-the-unknown-unknowns-of-global-warming-1438d934bdee 0:04 #1 Ozone…
