Planetary Health Check A Scientific Assessment of the State of the Planet
 (FIRST EDITION-2024)


Part 3 "The Interconnection& Drivers" is still not clarified - "everything 
is connected to everything"-))
That is, the conclusions and recommendations are also quite general: the 
limit of 1.5C.


Part 3.2.- Nothing about the biotic pump?


"Land System Change: How Deforestation Creates a Vicious Cycle of Forest 
Loss Fueling Freshwater Overuse, Biodiversity Loss & Climate Change
When agricultural expansion leads to forest loss, it reduces a wide range of 
ecosystem services and impacts several PB processes simultaneously. Forests 
often transpire more water than other land cover types, for exam- ple, by 
accessing deep soil water through their deep roots.38,39 Reduced forest 
cover means less transpiration, which in turn lowers at- mospheric moisture 
supply and reduces local and downwind precipitation..40,41 Additional- ly, 
the loss of forests increases near-surface wind speeds, which accelerates 
the drying of landscapes and reduces the time that mois- ture stays in the 
environment.42 Trees also re- lease organic compounds into the air that act 
as condensation nuclei — tiny particles that provide surfaces for water 
vapor to condense into clouds.43,44 Fewer trees mean fewer con- densation 
nuclei, leading to decreased cloud formation.42,45

With fewer clouds to reflect sunlight, more so- lar energy reaches the 
Earth's surface, caus- ing increased temperatures.46,47 Additionally, a 
reduced forest canopy means less shad- ing and cooling by 
evapotranspiration, which

further increases surface temperatures.48,49 Forest cover loss also results 
in open and dry understories, which elevate the likelihood of wildfires.50 
Higher wind speeds increase ero- sion, the process by which soil is worn 
away by wind and water.51 Reduced rainfall, higher temperatures, erosion, 
and increased water demands force farmers to use more freshwater for 
irrigation.52,53

Forest loss almost always results in direct biodiversity loss through 
habitat loss, degra- dation, or fragmentation.54 Furthermore, the 
climate-related impacts mentioned above also lead to biodiversity loss in 
the remaining nat- ural and semi-natural areas. This occurs due to drastic 
climatic shifts with high speed — meaning rapid changes in climate that 
species and ecosystems may not be able to adapt to quickly enough.55 All 
these factors contribute to the loss of biomass (the total mass of living 
organisms in an area) and carbon sinks (natural systems that absorb more 
carbon dioxide than they emit) as well as their resilience, further ac- 
celerating global climate change"

Viktor Gorshkov was more accurate not only in assessing, but also in 
explaining the natural mechanisms of life support, as well as in 
recommendations for stopping collapse!

Опубликован Доклад о состоянии здоровья планеты 2024. Точно так же, как 
анализ крови позволяет получить представление о состоянии здоровья 
человеческого организма и выявить проблемные области, эта проверка 
планетарного здоровья оценивает 13 контрольных переменных для определения 
степени нарушенности 9 планетарных границ системы Земли, определяющих её 
стабильность, адаптивность и способность поддерживать жизнь — общее 
состояние здоровья нашей планеты. Оценка 2024 года показывает, что были 
нарушены шесть из девяти планетарных границ: изменение климата, 
функциональная целостность биосферы, изменение экосистем суши, изменение 
пресноводной системы, биогеохимические потоки и влияние новых факторов. Все 
это свидетельствует о тенденциях дальнейшего усугубления нарушенности в 
ближайшем будущем. Три процесса, связанных с планетарными границами, 
остаются в пределах пространства безопасного существования человечества: 
подкисление океана (тенденция к увеличению и близка к границе), атмосферная 
аэрозольная нагрузка (глобальная тенденция к снижению) и разрушение 
стратосферного озона (отсутствие тенденции). Подробно
