Remember:

1. summer Arctic sea ice gone
2. demise of tropical ecosystems
3. high risk of global food calamity
4. most people facing water stress

All by around 2029.

RT if you'd like journalists to focus on this reality.

Hi

1. Summer Arctic sea ice disappearance within 15 years.

2034 most likely? Satellite observations suggest models underestimate, so 2020-2033 to be expected. A number of recent studies support this.ncei.noaa.gov/news/arctic-ic…

Major events of the next 15 years:

1. summer Arctic sea ice vanishes
2. rainforests turn to savannah
3. rapid deglaciation of Antarctica
4. Greenland ice sheet loss begins
5. all tropical coral reefs collapse
6. 50% of birds head to extinction

Greenland:

1. ice sheet now beyond tipping point and expected to completely disappear due to global warming of more than 2°C which will hit around 2030 - 2040

2. ice loss: 1/4 trillion tons per year

3. melt acceleration is exponential

4. sea level rise feedback has begun
The climate and ecological catastrophe is much worse than people think, but it will never be too late to take action to limit the inevitable damage.

'The Greenland ice sheet is expected to completely disappear due to global warming of more than 2.0°C'.
advances.sciencemag.org/content/6/2/ea…
"Models suggest that the Greenland Ice Sheet could be doomed at 1.5C of warming, which could happen as soon as 2030".

New climate models show that 1.5C could well hit in the 2020s, with 2C looking likely well before 2045 (one or two studies even say 2030).e360.yale.edu/features/as-cl…

Did you know?

1. Even moderate emissions cuts risk horrific death and destruction at 2C by 2035 (and that's ignoring very real methane, permafrost & vegetation feedbacks), then billions dead between 3C and 4C by 2045 - 2060.

2. The next IPCC assessment still won't include this.
'It is important to note that the range of carbon-cycle feedback estimates considered here may still be conservative, as many of these carbon-cycle models lack a number of feedbacks'

The intermediate RCP6.0 emissions scenario could see warming of up to 5C'carbonbrief.org/analysis-how-c…
UK Met Office and World Bank projections of utterly catastrophic 4C by 2060 (from 2009 & 2012) are more valid than ever, but, now even significant emissions reductions may not be enough.

Feedbacks still not captured by climate models mean risks are huge.climatecentral.org/news/co2-hits-…
