Remember

1. Arctic sea ice is nearly gone
2. 1000 bee species face extinction
3. coral reefs won't survive
4. rainforests are at a tipping point
5. soil: 90% infertile by 2050
6. today's trees may all die by 2060

For human survival, all these must be headline news in the 2020s.
1. summer Arctic sea ice set to disappear between 2020 and 2040.

Scientific reports from this year back up the projections of this 2013 research:

2. 1000 bee species face extinction in the US and Europe alone.

3. and 4.

Tropical corals & rainforests face collapse between 2020 and 2080 (most likely between 2025 and 2045 given current government plans for fossil fuel emissions, the accelerating rate of global warming, and projected heat waves and droughts).

5.
'Over 75% of the Earth's land area is already degraded, and over 90% could become degraded by 2050.'

6.
Forests (and therefore humans, along with 80% of terrestrial animals) 'are in big trouble if global warming continues at the present pace. Most trees alive today won't be able to survive in the climate expected in 40 years'.

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-…
