Because Agung is located near the equator, a major eruption with ash flying up into the stratosphere would have short-term climatic impacts that could last a few years. Agung last erupted in 1963 with an explosivity index of VEI 5, sending a plume of ash some 25 km into the atmosphere before leading to a cooling of 0.5°C. The eruption of Pinatubo in the Philippines in 1991 led to a global cooling of 0.5°C.
The National Snow and Ice Data Center (NSIDC) was forced to admit:
Overall, however, reduced melting and heavy early springtime snowfall may result in a net increase in Greenland’s ice mass this year for the first time this century.
The 2017 melt season has been less intense than recent years, and is below average melting for the 1981-to-2010 reference period. Surface melting has been low in the southeast, and has been limited to coastal regions at low elevations. “
Study: Melting sea ice could help cool the planet by flooding the atmosphere with particles that deflect sunlight. - The study wa published by the American Meteorological Society. Australian research suggests climate modelers have underestimated a natural “thermostat” that helps alleviate the rise in temperatures: immense quantities of reflective compounds, emitted by marine microbes, that act like a handbrake on global warming.
We have seen lots of claims about the temperature records for 2016 and 2015 proving dangerous man made warming. At least one senator stated that in a confirmation hearing. Yet HadSST3 data for the last two years show how obvious is the ocean’s governing of global average temperatures.
