Tackling the Biodiversity and Climate Crises Together, and Their Combined Social Impacts

The peer-reviewed workshop report is the product of a four-day digital workshop between consultants chosen by a 12-person Scientific Steering Committee assembled by the Intergovernmental Science-Coverage Platform on Biodiversity and Ecosystem Companies (IPBES) and the Intergovernmental Panel on Climate Change (IPCC) — the first-ever collaboration between these two intergovernmental our bodies.

International consultants determine key choices for options; First-ever collaboration between IPBES- and IPCC-selected scientists.

Unprecedented modifications in local weather and biodiversity, pushed by human actions, have mixed and more and more threaten nature, human lives, livelihoods and well-being round the world. Biodiversity loss and local weather change are each pushed by human financial actions and mutually reinforce one another. Neither will probably be efficiently resolved except each are tackled collectively.

That is the message of a workshop report, printed immediately by 50 of the world’s main biodiversity and local weather consultants.

The peer-reviewed workshop report is the product of a four-day digital workshop between consultants chosen by a 12-person Scientific Steering Committee assembled by the Intergovernmental Science-Coverage Platform on Biodiversity and Ecosystem Companies (IPBES) and the Intergovernmental Panel on Climate Change (IPCC) — the first-ever collaboration between these two intergovernmental our bodies.

The report finds that earlier insurance policies have largely tackled biodiversity loss and local weather change independently of one another, and that addressing the synergies between mitigating biodiversity loss and local weather change, whereas contemplating their social impacts, gives the alternative to maximise advantages and meet international growth targets.

“Human-caused local weather change is more and more threatening nature and its contributions to individuals, together with its potential to assist mitigate local weather change. The hotter the world will get, the much less meals, ingesting water and different key contributions nature could make to our lives, in lots of areas” mentioned Prof. Hans-Otto Pörtner, co-chair of the Scientific Steering Committee.

“Adjustments in biodiversity, in flip, have an effect on local weather, particularly by impacts on nitrogen, carbon and water cycles,” he mentioned. “The proof is obvious: a sustainable international future for individuals and nature remains to be achievable, but it surely requires transformative change with speedy and far-reaching actions of a kind by no means earlier than tried, constructing on bold emissions reductions. Fixing a few of the sturdy and apparently unavoidable trade-offs between local weather and biodiversity will entail a profound collective shift of particular person and shared values regarding nature — corresponding to shifting away from the conception of financial progress based mostly solely on GDP development, to at least one that balances human growth with a number of values of nature for high quality of life, whereas not overshooting biophysical and social limits.”

The authors additionally warn that narrowly-focused actions to fight local weather change can instantly and not directly hurt nature and vice-versa, however many measures exist that may make important constructive contributions in each areas.

Amongst the most vital accessible actions recognized in the report are:

Some centered local weather mitigation and adaptation measures recognized by the report as dangerous to biodiversity and nature’s contributions to individuals embody:

The report authors stress that whereas nature gives efficient methods to assist mitigate local weather change, these options can solely be efficient if constructing on bold reductions in all human-caused greenhouse fuel emissions. “Land and ocean are already doing quite a bit — absorbing virtually 50% of CO2 from human emissions — however nature can’t do all the pieces,” mentioned Ana María Hernández Salgar, Chair of IPBES. “Transformative change in all components of society and our economic system is required to stabilize our local weather, cease biodiversity loss and chart a path to the sustainable future we would like. This may also require us to deal with each crises collectively, in complementary methods.”

Highlighting the significance of the co-sponsored workshop, Dr. Hoesung Lee, Chair of the IPCC, mentioned: “Climate change and biodiversity loss mix to threaten society — typically magnifying and accelerating one another. By specializing in synergies and trade-offs between biodiversity safety and local weather change mitigation and adaptation, this workshop superior the debate on methods to maximize advantages to individuals and the planet. It additionally represented an vital step in collaboration between our two communities.”

“It could be unimaginable to realize win-win synergies, and even handle the tradeoffs between local weather and biodiversity actions in each single patch of a panorama or seascape,” mentioned Prof. Pörtner, “However attaining sustainable outcomes turns into progressively simpler when integrating a mixture of actions at bigger spatial scales, by cross-border collaboration and joint consultative spatial planning, which is why you will need to additionally handle the lack of efficient governance techniques and mechanisms to enhance integration between options for local weather change and biodiversity.”

The Governments of the United Kingdom and of Norway co-hosted the digital workshop. “That is a fully crucial 12 months for nature and local weather,” mentioned Lord Zac Goldsmith, UK Minister of State for Pacific and the Atmosphere. “With the UN Biodiversity Convention in Kunming, and the Glasgow Climate Change Convention in the UK, now we have a chance and duty to place the world on a path to restoration. This massively beneficial report by the consultants of IPBES and IPCC makes it clear that addressing biodiversity loss and local weather change collectively gives our greatest probability of doing so.”

Sveinung Rotevatn, Norwegian Minister for Climate and Atmosphere added: “Insurance policies, efforts and actions to unravel the international biodiversity and local weather crises will solely succeed if they’re based mostly on the finest information and proof, which is why Norway welcomes this knowledgeable workshop report. It’s clear that we can’t clear up these threats in isolation — we both clear up each or we clear up neither.”

Paying tribute to the work of all the authors and knowledgeable reviewers, the Govt Secretary of IPBES, Dr. Anne Larigauderie, additionally recalled the current and tragic passing of Prof. Robert Scholes, the different Co-Chair of the workshop’s Scientific Steering Committee, and his many contributions to each the IPCC and IPBES.

You will need to observe that the workshop report has not been subjected to IPBES or IPCC assessment, and that IPBES and IPCC co-sponsorship of the workshop doesn’t suggest IPBES or IPCC endorsement or approval of the workshop or its conclusions.
