The hottest four years on record for atmospheric temps are 2015, 2016, 2017 and 2018. However: 2018 was the hottest year on record for LaNina years!
2018 was the hottest year on record for global ocean temperatures. The hottest four years on record for global ocean temperatures are 2014, 2015, 2016, 2017 and 2018.
ATMOSPHERIC CO2 CROSSES 414 PPM FOR THE FIRST TIME.
Driving the exponential rate increase in global warming is the continued increases in CO2 emissions, including the US. Worse is expected this year.
This is actually less alarming than the amount of CO2 being absorbed by the ocean. And then there is the methane feedback loop: as the permafrost thaws, the CH4 that had been trapped is no longer trapped. This process is just beginning, but is accelerating.
GREENLAND SHEET ICE AT THE TIPPING POINT…NOW
There are trillions of tons of freshwater ice sitting on top of Greenland…for now.
Warming waters in fjords are melting coastal glaciers now, even in the middle of winter. Greenland’s ice sheet is second only to Antarctica and contributes about 20% to sea level rise. This is fresh water being dumped in the ocean, which changes salinity, which screws up a lot of other things.
The feedback loops: Visit our primer on how global warming both drives and is driven by the various types of ice. Link.

Antarctic land ice is melting 6X faster than 1980's rate: Jan 13 - Two alarming new research reports (University of California) tell us that the rate of Antarctic land ice melt has increased 280% over the past four decade. The current rate - which is accelerating - is enough to add one millimeter a year in sea level rise. New estimates indicate an end-of-century rise over near 200 ft. Ice has increased from 40 gigatons / year from 1979-90 to 252 gigatons per year from 2009-17. Six times faster.
Ocean waters have warmed about 40% faster than previously understood Jan 10 - The global ocean has been absorbing massive amounts of heat over the past 20 years. The ability of the ocean to absorb excess heat has moderated the atmospheric increase to some degree, but once heat is absorbed it remains in the oceans much much longer. The significant increase in extreme weather, landslides, hurricanes and storms is attributable to the warming seas.
Other current data:
- 2018 has been confirmed as the 4th warmest year on record. The four hottest are 2015, 2016, 2017 and 2018. The is all the more ominous due to the fact that 2018 was a La Nina year, which are typically cooler than 2016 years.
- Jan 10: Ocean waters have warmed to an unprecedented degree, far more quickly than projected, and at an alarming and accelerating rate. Some consequences.
- US carbon emissions rose again in 2018 after leveling off in previous years.
- 2018 record year for global heat records
- Antarctic sea ice pack extent at all time record low for early Jan.
- Recurring Solomon Island Flooding
- Wildfire apocalypse Tasmania
- Ongoing jellyfish incursion brought about by pollution and warming
- Glaciers going dark with soot, reduced ability to sunlight back into space + absorb more heat energy. This is one of two major feedback loops that accelerate global warming.
- The once stable land glaciers in East Antarctica are melting. The Totten Glacier alone contains ten feet of sea level rise.
