question - earth system boundaries - biodiversity - how do we reconcile these boundaries with climate departure? - Does the term "functional integrity" imply autonomy from climate feedbacks? Obviously, climate feedback plays a huge role in determining biodiversity health - In 2013, Mora et al. found that climate departure, the year in which a climate variable moves out of the historical bounds will occur everywhere on the planet, regardless of an aggressive RCP pathway being taken. In this study, climate departure was found to take place (relative to 2013) - 37.5 years in the future under RCP45, or - 22.5 years in the future under RCP85 - It would seem that the biodiversity boundaries should take into consideration climate departure as species extinction and ecological system disruption is projected to occur, regardless of whether RCP45 or RCP85 is adopted. - Currently, we are still on a Business-As-Usual trajectory, but since 2013, scientific research has moved the danger threshold even lower so climate departure dates are likely even sooner than those calculated in the 2013 Mora paper

If our interest is to attempt to create a global collective action campaign to address our existential polycrisis, which includes the climate crisis, then how do we mobilize at the community level in a meaningful way?
I suggest that this must be a cosmolocal effort. Why? Knowledge sharing across all the communities will accelerate the transition of any participating local community.
Building such a collaboration system requires expert knowledge. Once built, however, it requires testing in pilot communities. This is where a partnership can take place

A widely publicized study published last year by researchers at the University of Northern Arizona analyzed satellite images taken between 1985 and 2019. They show that large parts of the boreal forest have “browned” (i.e., died) in the south and greened with trees and shrubs in the north. If this shift, long hypothesized as a future outcome of warming, is already underway, the effects will be profound, transforming natural habitats, animal migration and human settlements.
Cities across the country will begin to reach “climate departure”: a symbolic rubicon, after which a climate falls completely outside historical norms.
An unprecedented heatwave occurred in the Pacific Northwest (PNW) from ~25 June to 2 July 2021, over lands colonially named British Columbia (BC) and Alberta (AB) in Canada, Washington (WA), and Oregon (OR) in the United States.
None of the 28 streams Cunningham and his colleagues studied hit summertime highs warmer than 25.9 C, the point where warming water can become lethal. But in four rivers, temperatures climbed past 20.3 C, the threshold where some have found juvenile coho stop growing.

we humans depend on the natural world 00:07:01 [Music] but what we depend on is healthy ecosystems [Music] that are made up of a complex mix of plants and animal species each one has a 00:07:24 role to play and you know I see it as like a beautiful living tapestry and as an animal or plant species disappears from that ecosystem it's like pulling 00:07:38 out a thread and if enough threads are pulled then the tapestry will hang in tatters and the ecosystem will disappear
you can imagine that that if that's happening today and climate change hasn't really even hit yet and biodiversity loss really hasn't even hit badly yet or at least this hasn't hit widespread 00:35:45 badly

A crucial year for understanding how ocean warming affects marine life
To provide an indication of the projected timing of climate depar-ture under alternative greenhouse gas emissions scenarios, we havedeveloped an index that determines the year when the values of agiven climatic variable exceed the bounds of historical variabilityfor a particular location (Fig. 1a).
There are temperature ceilings that humans and mammals (and many other animals) cannot survive, if breached. What those limits are, and what happens when they are crossed, will have profound implications for agriculture and biodiversity in a warming world.

The projected timing of climate departurefrom recent variability
Although several studies have documented theareas on Earth where unprecedented climates is likely to occur inresponse to ongoing greenhouse gas emissions24,25 , our understandingof climate change still lacks a precise indication of the time at which theclimate of a given location will shift wholly outside the range of his-torical precedents.To provide an indication of the projected timing of climate depar-ture under alternative greenhouse gas emissions scenarios, we havedeveloped an index that determines the year when the values of agiven climatic variable exceed the bounds of historical variabilityfor a particular location (Fig. 1a). We emphasize that although ourindex commonly identifies future dates, this does not imply thatclimate change is not already occurring. In fact, our index projectswhen ongoing climate change signals the start of a radically differentclimate.
Climate departure for a specific location on the planet is defined as the year when the values of a given climatic variable exceed the bounds of historical variability.
Climate is a primary driver of biological processes, operating fromindividuals to ecosystems, and affects several aspects of human life.Therefore, climates without modern precedents could cause large andpotentially serious impacts on ecological and social systems 1–5 . Forinstance, species whose persistence is shaped by the climate canrespond by shifting their geographical ranges 4–7 , remaining in placeand adapting 5,8 , or becoming extinct 8–11 . Shifts in species distributionsand abundances can increase the risk of extinction 12 , alter communitystructure 3 and disrupt ecological interactions and the functioning ofecosystems. Changing climates could also affect the following: humanwelfare, through changes in the supply of food 13 and water 14,15 ; humanhealth 16, through wider spread of infectious vector-borne diseases 17,18,through heat stress19 and through mental illness20; the economy, throughchanges in goods and services21,22; and national security as a result ofpopulation shifts, heightened competition for natural resources, viol-ent conflict and geopolitical instability23. Although most ecological andsocial systems have the ability to adapt to a changing climate, themagnitude of disruption in both ecosystems and societies will bestrongly determined by the time frames in which the climate will reachunprecedented states1
As climate departure is projected to occur under all IPCC RCP scenarios, this implies profound changes will take place everywhere on the planet.
The biosphere will react to this unprecedented shift in equally unprecedented ways. Each species has a comfort zone temperature band to exist within. If the temperature falls outside that zone, it can remain in place and adapt, shift geographical location (migration) or go extinct.
In an ecosystem, species all depend on each other. When a number of these shift their patterns, it will affect the others, increasing total ecosystem disruptions. Since human activity is dependent on nature, this will also ripple up to humans in a variety of ways.
Ecological and societal disruptions by modern climate change are critically determined by the time frame over whichclimates shift beyond historical analogues. Here we present a new index of the year when the projected mean climate ofa given location moves to a state continuously outside the bounds of historical variability under alternative greenhouse gasemissions scenarios. Using 1860 to 2005 as the historical period, this index has a global mean of 2069 (618 years s.d.) fornear-surface air temperature under an emissions stabilization scenario and 2047 (614 years s.d.) under a ‘business-as-usual’scenario. Unprecedented climates will occur earliest in the tropics and among low-income countries, highlighting thevulnerability of global biodiversity and the limited governmental capacity to respond to the impacts of climate change.Our findings shed light on the urgency of mitigating greenhouse gas emissions if climates potentially harmful to biodiversityand society are to be prevented.
Read this abstract and let the profound implications sink in!
In other words, climate departure will occur REGARDLESS OF WHICH RCP (Representative Concentration Pathway) is taken, whether it is the best or the worst path as defined by IPCC, climate departure will happen! (Climate departure is defined in the second paragraph of the paper) Using historical data between 1860 and 2005 for defining normative climate around the globe, If the worst IPCC emissions scenario (RCP85) happens, climate departure (projected near-surface air temp of the average location on earth) around the globe at the average location happens by 2047 (+/- 14 years). if the BEST IPCC emissions scenario (RCP45) happens, then.climate departure still happens but moves beyond historical variability by 2069 (+/-18 years)
In other words, NO MATTER WHAT RCP of the ones IPCC publishes we take, climate departure is going to happen! How does the planet plan for such a drastic shift of every ecosystem on the globe? If it is unavoidable, then resiliency will be a key intervention.
The projected timing of climate departurefrom recent variability
gloss - Climate Departure
Climate Departure is the year that the local climate changes so radically that local species no longer recognize it as their environment.
for example arctic char the fish species that's already 00:09:00 all across the arctic region living at its temperature level about 24 degrees celsius in freshwater ecosystems one fraction of a decree further and we 00:09:13 will enter into a cycle of fish death events that will cascade in food security loss of culture and many other things of this keystone species on the aquatic ecosystems for 00:09:25 communities and nature alike
See Camilo Mora's nature 2013 paper on climate departure:.https://www.nature.com/articles/nature12540
arctic fox is now gone it's no longer nesting in in 00:09:38 finnish army and arctic areas and uh its habitats are overtaken by red fox more southern and boreal species so the species on the move is one of the factors that's really altering the kind 00:09:51 of life that we know here
Arctic Fox is being replaced by Red Fox
