🛢 The fact that human activity affects the Earth’s climate and ecosystems is not groundbreaking news for decades. But now more than ever this risks the stability of the entire planet. 💡 In 2009, the Stockholm Resilience Center's former director, Johan Rockström, together with a group of 28 internationally renowned scientists proposed the concept of planetary boundaries. 📊 In 2023, for the first time ever all nine planetary boundaries were assessed and six of them are now transgressed. 🌍 "A global focus on climate change alone is not sufficient for increased sustainability. Instead, understanding the interplay of [the planetary] boundaries, especially climate, and loss of biodiversity, is key in science and practice".

"Currently, anthropogenic perturbations of the global environment are primarily addressed as if they were separate issues, e.g., climate change, biodiversity loss, or pollution. This approach, however, ignores these perturbations’ nonlinear interactions and resulting aggregate effects on the overall state of Earth system. Planetary boundaries bring a scientific understanding of anthropogenic global environmental impacts into a framework that calls for considering the state of Earth system as a whole." - Richardson et al., 2023 #PlanetaryBoundaries #PlanetaryBoundaries2023 quantified #ClimateAction #ClimateChange #Resilience #scienceandenvironment https://lnkd.in/gG5JV3d9

Well deserved! The 2024 Tyler Prize for Environmental Achievement will go to Johan Rockström who led the team of international researchers who originated the planetary boundary framework in 2009. The theory defines a scientifically based “safe operating space for humanity” to safeguard stable Earth conditions established in the Holocene when civilization arose, with the intention of preventing dangerous tipping points in the Anthropocene — a new era in which humanity has the capacity to wreak havoc on Earth systems. In a new interview with Mongabay, Rockström discusses how the planetary boundaries framework formulates quantified safe limits to protect nine Earth systems (including climate, biodiversity, freshwater and more), all vital for sustaining life and he shares some updates on this cutting-edge research. “Planetary sustainability is a security issue because staying within planetary boundaries gives us stable societies, food security, water security and reduces conflicts,” says Rockström. “Placing planetary boundaries at the UN Security Council positions sustainability, climate, biodiversity, water, where it belongs — in security.” #planetaryhealth #planetaryboundaries #environment #environmental #environmentalhealth #environmentalpolicy #foodsystems #foodsystemtransformation #sustainablefoodsystems #sustainability #climate #climatechange #climatecrisis #biodiversity #biodiversityloss #dietitians #nutritionists #globalfoodsecurity #globalsecurity

"Earth beyond six of nine planetary boundaries" 🌎 🚫 Last week, a new study revealed that six out of nine planetary boundaries have been crossed, highlighting the urgency of our collective action. As the Stockholm Resilience Centre mentioned, "crossing boundaries increases the risk of generating large-scale abrupt or irreversible environmental changes. Drastic changes will not necessarily happen overnight, but together the boundaries mark a critical threshold for increasing risks to people and the ecosystems we are part of."

For the first time, an international team of scientists from the Stockholm Resilience Centre quantified the limits of our planet. They published an outline of planetary resilience by mapping out nine planetary boundaries. The planetary boundaries show the safe limits within which humans can live and develop. Research shows that we have already crossed six of these nine boundaries. These six include: - climate change - biodiversity (biosphere integrity) - freshwater consumption - chemical and plastic pollution (novel entities) - nutrient pollution (biogeochemical flows) - forest cover (land-system change) The news are not great and underscore the need for capital, dedicated time, and talent to create a space within which humanity can continue to develop and thrive for generations to come. 🌍 Learn more about the planetary boundaries and their current state via the link below. The study was published in September 2023.

Today's #Champion in the #Community of #Climate #Changemakers is the Stockholm Resilience Centre who came up with the #planetaryboundaries concept which presents a set of nine planetary boundaries (including for instance: ocean acidification, stratospheric ozone depletion) within which humanity can continue to develop and thrive for generations to come. Six boundaries are now transgressed (in the red) and pressure is increasing on all boundary processes except ozone depletion. The #planetarybounderies concept has equiped us with a clear and simple way to communicate the need for action, and has obtained enormous interest within science, policy, and practice. #savetheplanet #positivechange #climateimpact #climatecrisis #sustainability --- I am tired of all the messages about how bad our planet is doing and about all the actions that are not being taken. Instead, #everyday I share an initiative that is already making positive change to our planet. I invite you to do the same. #FiveCs4Earth https://lnkd.in/epy8Szqm

The ocean, a mysterious realm of endless discoveries - a metaphorical abyss of knowledge waiting to be unraveled. 🌊 Today, after delving into an enlightening article on the biggest stories in ocean science over the past decade, I find myself pondering the intricate dance of tides and research. 🔍 The exploration of marine biodiversity, akin to peeling back the layers of a well-kept secret garden, revealing the wonders of underwater life that thrive in the depths unseen by many. 🌍 Climate change impacts, a global symphony where each wave echoes the urgent need for collaborative efforts to protect our oceans from the looming threats, mirroring the delicate balance of nature endangered by human actions. 🕵️♂️ Scientific breakthroughs, like uncovering buried treasures on the ocean floor, shedding light on the hidden marvels and mysteries that stir the curiosity of both experts and enthusiasts alike. 🌟 As we navigate the vast seas of knowledge, let's remember that every ripple we create in our understanding of the ocean's secrets contributes to the ocean of wisdom we collectively sail upon. Let's continue our voyage towards exploration, conservation, and awe-inspiring revelations to safeguard the ocean's legacy for generations to come. https://lnkd.in/eQwcGuG

How is the carbon cycle responding to climate change? Accurately quantifying and projecting changes in the carbon balance is central to understanding and projecting climate change and its impacts on ecosystems and biodiversity. This in turn provides a necessary basis for mitigation strategies. In the strategic research area BECC (Biodiversity and Ecosystem services in a Changing Climate), one major focus is to reduce uncertainty in the carbon cycle and its responses to anthropogenic and biophysical drivers. Listen to Edith Hammer, the lead researcher at BECC for this theme, as she explains more and give some practical examples on how she and her colleagues tackle this challenge. BECC engage about 300 researchers at Lund University and the University of Gothenburg, bringing together scientists from the natural and social sciences. The research area is hosted by CEC.

I came across an article of Camilla Drejer today. It's about the "tunnel environmental vision". And this problem really exists! What do you usually hear? I think I won't be wrong if say it's Climate. Maybe recently Biodiversity came into the news. Maybe a little bit - Plastic pollution. Doesn't it remind you something? Or maybe you think "Why exactly are these themes"? If you look into research of Stockholm Resilience Centre you'll find the concept of Planetary boundaries. You can read more about the concept here - https://lnkd.in/eP7b3Es4 The main idea of this concept is good. But! Firstly, it's still in the developing stage and some boundaries haven't been counted yet. Secondly, some themes are presented as more important than others. Thirdly, as stakeholders see the most sensitive boundary - all forces are there. Unintentionally, the Planetary Boundaries concept creates such tunnel vision. But it's essential to remember that Nature is a complex system. There are no such individual separate components. You can't talk about Climate change without biodiversity, or pollution, or acidification (by the way, not only the oceans), etc. And protection measures should be also complex! #scienceandenvironment When you're protecting one animal actually you are protecting its habitat which includes soils, air, vegetation, water, lands, and so on, and so on! If you would like to discuss more please do not hesitate to contact me. I'm interested to hear different opinions.
