The UW has released its assessment for Arctic ice volume for Jun 2018.

The number is 17218 km3, the 6th lowest June volume in the sat record.

Using NOAA's ice extent/area for the past 40 years we can also
approximate the average sea ice thickness. A tipping point is
reached when the average thickness can be melted in a single summer --
it means the end of "permanent" (aka "multi year") sea ice.

From the data about 1.5m of sea ice can be melted in the usual 21st cent

For PIOMAS ice volume the top10 lowest Arctic seaice volumes are now:

Year vol
(000s of km3)
2017 15.4
2012 16.002
2016 16.493
2011 16.5
2010 17.142
2018 17.218 <-- new #6 lowest vol
2013 17.538
2014 17.68
2015 18.557
2007 19.19

For calculated sea ice av thickness the record lows for June are now:

Year av thickness
2017 1.4366 <-- "past" tipping point
2012 1.4997 <-- "past" tipping point
2011 1.5349
2013 1.5438
2016 1.5935
2014 1.6029
2018 1.6077 <-- 7th lowest sea ice thickness
2010 1.6187
2015 1.7056
2007 1.7103

(NOTE: thickness has a counterintuitive aspect. As summer progresses
the av thickness can get larger as the thinner ice disappears).

UK counter-terrorism police confirm [another!] couple poisoned by nerve
agent Novichok

Counter-terrorism police are now investigating whether the case is linked
with the poisoning of former Russian spy Sergei Skripal but say there is no
evidence yet that the couple were deliberately targeted.

How use of land in pursuit of 1.5C could impact biodiversity
"For biodiversity, the benefits of holding warming to 1.5C rather than
2C are clear," writes Prof Pete Smith in a guest post for Carbon
Brief. "But there is another side to how climate change could affect
biodiversity - through the land management decisions we take as part
of efforts to reduce greenhouse gas (GHG) levels in the atmosphere,"
Smith writes. These decisions include how and whether the world ramps
up "negative emissions" to increase the CO2 absorbed by the land
surface, he says, with potential risks to biodiversity.

Flood damage costs under the sea level rise with warming of 1.5C and 2C
Without efforts to curb global warming, the annual damage costs of
rising sea levels could hit $14tn a year by 2100, a new study
estimates, or even $27tn a year if sea level rise hits 1.8 metres. For
the Paris temperature limits, annual damages from sea level rise at 2C
of warming are likely to cost $1.4tn a year more than at 1.5C, the
researchers find. "Upper middle income countries" are projected to
experience the largest increase in annual flood costs - as much as 8%
GDP of national income - with China particularly at risk. Adaptation
could potentially reduce these costs by a factor of 10, the
researchers note. -- Environmental Research Letters

Inclusive climate change mitigation and food security policy under
1.5C climate goal
An "inclusive policy design" can help avoid negative impacts on food
security of land use measures taken to mitigate climate change, a new
study suggests. Large-scale deployment of land-related options, such
as afforestation and bioenergy production, has the potential to
increase food prices, and hence raises food security
concerns. However, food-security support through dedicated policies,
such as international aid and bioenergy tax, can shield impoverished
and vulnerable people from the additional risk of hunger, the
researchers say. -- Environmental Research Letters
