Doomsday by 2021?
5
November, 2018
The
Doomsday Clock, by the Bulletin
of the Atomic Scientists,
constitutes a potent symbol of the danger we're in. When taking the
'minutes to midnight' from statements 1991 to 2018, an added trend
points at Midnight by 2021. Will it be Doomsday by 2021?
The 2018 Statement said that "world leaders failed to respond effectively to the looming threats of nuclear war and climate change. [ . . ] Global carbon dioxide emissions have not yet shown the beginnings of the sustained decline towards zero that must occur if ever greater warming is to be avoided."
Recently, Fatih Birol, IEA Executive Director, said: "We expect energy-related CO2 emissions will increase once again in 2018 after growing in 2017."
Next to carbon dioxide, the outlook for other greenhouse gases is also very worrying and the situation could deteriorate very rapidly, as further described below.

As
above image shows, oceans continue to warm up, due to the rise in
greenhouse gas levels in the atmosphere.

The
image on the right shows sea surface temperature anomalies as high
as as 7.1°C (or 12.7°F) in the Bering Strait (at the green circle)
on October 15, 2018.
Warmer oceans result in stronger cyclones. The next image on the right shows that Typhoon Yutu was forecast to reach an Instantaneous Wind Power Density (WPD) as high as 207647 W/m² at 850 mb and wind speeds as fast as 268 km/h or 167 mph at the green circle, i.e. at 18.50° N, 124.00° E, on October 30, 2018, 00:00 UTC.
Cyclones can suddenly push huge amounts of salty warm water into the Arctic Ocean. The danger is that a strong influx of salty warm water into the Arctic Ocean will trigger destabilization of hydrates in sediments, resulting in massive eruptions of methane from the seafloor of the Arctic Ocean, as described in earlier posts such as this one.
This methane could cause temperatures to suddenly rise strongly, triggering extreme weather events such as storms, flooding, heatwaves and fires across the Northern Hemisphere that could devastate crops, take down power grids and cause meltdowns of nuclear power plants, making it appropriate to warn that it could be Doomsday by 2021.
The situation is dire and calls for comprehensive and effective action, as described at the Climate Plan.
