Antarctic ice is vanishing at its fastest rate in recorded history whilst Greenland ice melt is accelerating exponentially. This will have catastrophic consequences for all life on Earth by 2029. 
Is 'catastrophic' by 2029 an absurd exaggeration?
Well, no, it isn't:
⚠️ Greenland's ice melting alters air circulation leading to extreme weather like July 2019's heatwaves.
2029 heatwaves, exacerbated by additional factors, will surely be far worse.euronews.com/2019/08/01/gre…

But will this be catastrophic for all life on Earth?
Pretty much.
Changes in the Cryosphere are not happening in isolation. As we move towards 1.5- 2C by 2029, feedback processes will continue to radically affect ecosystems from the tropics to the Arctic.scientificamerican.com/article/tropic…

The truth is that climate catastrophe is here already for 100s of millions of people.
'Climate shocks and conflict will continue driving food insecurity...'
Over 250 million are already experiencing 'acute hunger' or are on 'the cusp of severe hunger'.

1/ 'even if the Paris Accord target of a 1.5 °C to 2.0 °C rise in temperature is met, we cannot exclude the risk that a cascade of feedbacks could push the Earth System irreversibly onto a “Hothouse Earth” pathway'.

2 cont'd/ 'Sustained warming of the northern high latitudes as a result of this process could accelerate feedbacks or activate tipping elements in that region, such as permafrost degradation, loss of Arctic sea ice, and boreal forest dieback.'
3/ 'While this may seem to be an extreme scenario, it illustrates that a warming into the range of even the lower-temperature cluster (i.e., the Paris targets) could lead to tipping in the mid- and higher-temperature clusters via cascade effects...
3 cont'd/ Based on this analysis of tipping cascades and taking a risk-averse approach, we suggest that a potential planetary threshold could occur at a temperature rise as low as ∼2.0 °C above preindustrial (Fig. 1).'

Ecological calamity is here now.
By 2029 it will be worse.
Have scientists been 'underestimating how global climate change will affect biodiversity and the number of extinctions that will occur'?newsweek.com/climate-change…
