V1 is the critical engine failure recognition speed or takeoff decision speed. It is the speed above which the takeoff will continue even if an engine fails or another problem occurs, such as a blown tire.[9] The speed will vary among aircraft types and varies according to factors such as aircraft weight, runway length, wing flap setting, engine thrust used and runway surface contamination, thus it must be determined by the pilot before takeoff. Aborting a takeoff after V1 is strongly discouraged because the aircraft will by definition not be able to stop before the end of the runway, thus suffering a "runway overrun".[34]
V1 is defined differently in different jurisdictions:
The US Federal Aviation Administration defines it as: "the maximum speed in the takeoff at which the pilot must take the first action (e.g., apply brakes, reduce thrust, deploy speed brakes) to stop the airplane within the accelerate-stop distance. V1 also means the minimum speed in the takeoff, following a failure of the critical engine at VEF, at which the pilot can continue the takeoff and achieve the required height above the takeoff surface within the takeoff distance."[7]
Transport Canada defines it as: "Critical engine failure recognition speed" and adds: "This definition is not restrictive. An operator may adopt any other definition outlined in the aircraft flight manual (AFM) of TC type-approved aircraft as long as such definition does not compromise operational safety of the aircraft."[8]

OP
It's time to #drawdown CO2 to maintain any hope of agricultural, economic and political stability.

I hadn't checked the climatologists on twitter recently. Just did and I'm scared.

Well, no. That time was 40 or more years ago. Agricultural, economic and political stability are gone, washed away by #extremeweather events

The ones I follow are beating themselves up for not sounding the alarm effectively, earlier. And they're talking about how politics watered down the IPCC report so that it was overly conservative.
For all the talk about carbon sequestration--and don't get me wrong, we should do it!--I don't see how we can plant enough trees and change our agricultural systems enough to offset the CO2 released by the fires and permafrost.
