May 2019 - April 2020:

'Deforestation in the Brazilian Amazon over the past 12 months has reached the highest level since monthly tracking began in 2007.' news.mongabay.com/2020/05/amazon…
December 2019:

'researchers are seeing evidence in both the atmosphere and on the ground that this tipping point has been reached and will worsen if no action is taken immediately to reverse the situation.'

'The tipping point is here, it is now,’ top Amazon scientists warn:

'It is urgent...that Brazil move away from unsustainable agribusiness monocultures of cattle, soy, and sugarcane, while launching a major reforestation project on already degraded lands'

“I would think of the summer ice disappearing as the true tipping point we’ve all been afraid of..."

Veerabhadran Ramanathan, Scripps Institution of Oceanography, discoverer of role of CFCs in amplifying global warming and destroying the ozone layer

'The reason Arctic ice is shrinking so fast, and why scientists are worried about it continuing, is one and the same.

There is a well-known feedback loop in the Arctic, caused by the reflectivity of ice and the darkness of the ocean.'

'When the Arctic Ocean is covered by lighter, white ice, it reflects more sunlight back to space. But when there is less ice, more heat gets absorbed by the darker ocean — warming the planet further. That warmer ocean then inhibits the growth of future ice...'

1. “Temperature increases beyond 1C may elicit rapid, unpredictable and non-linear responses that could lead to extensive ecosystem damage.”

2. '2C would be enough to threaten life as we know it.'

3. We're set to go over 2C of global warming by the 2040s

Thread:
The quotes come from this 2017 article.

“The consequences of failing to keep the temperature below 1.5C will be to wilfully condemn hundreds of millions of the poorest citizens of Earth to certain deaths from the severe impacts of climate change.”

amp.theguardian.com/environment/20…
From 2016: "I think it is fair to say that there is literally no chance of making the 1.5C target".

'Earth is on track to sail past the two degree Celsius (3.6 degrees Fahrenheit) threshold for dangerous global warming by 2050'.

Emissions from permafrost thaw could raise global temperatures by 0.3C (including 0.2C before 2100) by the next century.

However, some of the coldest permafrost (expected to remain stable until the 22nd century) now looks likely to degrade more quickly than previously thought.

'If greenhouse gas emissions continue to increase at current rates, this warming will lead to the widespread thawing of permafrost and the release of hundreds of billions of tonnes of CO2 and billions of tonnes of CH4'

'Emissions from melted permafrost could raise global temperatures by 0.2 C' by 2100, and 0.3C by the 22nd century.

However, permafrost has been thawing far more quickly than expected since this 2015 study (in some cases 70 years earlier). rcinet.ca/en/2015/09/24/…
