The last chapter on climate change books don't need to tell us how "it's not to late, that if we just work together and change our ways..." The time of action is well past us. You can call me a doomerist, but humanity has made it choice long ago: "WE WILL NOT CHANGE".

Yeah, they do need to do that.  We do need to change.  Not because change avoids a very bad outcome at this point, but because change will avoid an unthinkable outcome.  We are at a point where we can’t avoid a very bad outcome.  It’s impossible.  Nothing to be done about what’s baked in at this point.  The past has passed.  Anything we do now will help to avoid the unthinkable.  It’s still a necessary thing to do.  What’s the alternative?  Not calling on people to take action?  Rage, rage against the dying of the light and all that.  Think of it this way.  You have a patient that’s bleeding out.  You can stop the bleeding, but not completely.  What do you do?  You stop the bleeding as best you can.  It’s not a perfect metaphor, I know.  I went into climate resilience because of the disaster that’s already baked in, I stay because of the worse disaster that’s coming.  Change, whether we intentionally embrace it or now, will happen.  Change is (shout out to the amazing Octavia E. Butler).  I believe it will likely be forced upon us.  It will be terrible.  One good thing to do now is to frantically claw back emissions.  The best thing to do is find an adaptive and resilient path through the future assuming emissions continue.  I need everyone to know that the adaptive and resilient paths are by no means easy or comfortable or attractive.  Adaptation and resilience are the best out choices out of a truly dismal set of options.  But, goddamnit, I have to say I tried.

The IPCC reports, from what I understand, need approval from world governments, and by extension (since they are very corrupt), from businesses interests. That's why sometimes those estimates use an awful concept when talking about the real world: Accounting tricks.

Accounting tricks must work for business and corrupt governments, but when we are talking about physical reality, it doesn't make sense. You may not count US Army's emissions but they're still there. Reality is not convenient like that. The fact that grown people rely on magical thinking like this... let's face it, it's delusional.

The IPCC is the United Nations body for assessing the science related to climate change. 

“The main activity of the IPCC is the preparation of reports assessing the state of knowledge of climate change. These include assessment reports, special reports and methodology reports. To deliver this work programme, the IPCC holds meetings of its government representatives, convening as plenary sessions of the Panel or IPCC Working Groups to approve, adopt and accept reports. Plenary Sessions of the IPCC also determine the IPCC work programme, and other business including its budget and outlines of reports. The IPCC Bureau meets regularly to provide guidance to the Panel on scientific and technical aspects of its work. The IPCC organizes scoping meetings of experts and meetings of lead authors to prepare reports. It organizes expert meetings and workshops on various topics to support its work programme, and publishes the proceedings of these meetings.  To communicate its findings and explain its work, the IPCC takes part in outreach activities organized by the IPCC or hosted by other organizations and provides speakers to other conferences.” 

Have you ever even read an IPCC report?  Please educate yourself further.

As for the “accounting tricks,” I agree.  It does amount to magical thinking.  We aren’t going to cap and trade and carbon offset our way out of this.  Your beef isn’t with climate scientists, it’s with economists and policy makers.
