The Double Crisis: Climate & Biodiversity | DLD Nature

with Johan Rockström (Potsdam Institute for Climate Impact Research)

In his DLD Nature presentation, leading climate scientist Johan Rockström
(Potsdam Institute for Climate Impact Research) makes a compelling case that
climate change and biodiversity loss are deeply interconnected.

Protecting up to 50% of nature is necessary to maintain the planet’s buffering
capacity, and the Paris climate goals cannot be met without protecting nature as
well, Rockström makes clear.

“70% of the population of vertebrates are gone since 1970. The weight of
livestock plus humans now outpast the weight of wild mammals”, he notes. “This
is drama at a planetary scale.”

boundaries framework, and how sustainable economic development is related to
prosperity on a stable and resilient planet

One of the most important speakers in this space is Mr Rockstrom. Yet....after three days up, there are only 1.2k views. Lady Ga Ga should have delivered the talk instead - what does it take?

[BLUESKYX]

Good presentation but we are NOT at 1.2 deg C...it is long gone; We are surpassing 1.5 deg C as James Hansen said and others

[cynthiatheresasuzara]

We need to protect nature and keep the big trees standing, and we should all consider eating a plant based

[thf]

Saddened by the call for economic growth. What is the sole purpose for saving our home?

[ulrichschonhardt]

50 years of ecological overshoot!! His optimistic closing words sound ridiculous to me. We're also destroying the Congo rainforest.

[Jibbolino]

As expected, Rockström ended the lecture by administering some Hopium for the masses and leaving the audience with the sensation that "The Window of Opportunity" is still open.

[stoodmuffinpersonal]

This is serious stuff, and yet. I feel like more and more is done to stop anything done about it, than fix it.

[TomZanetic]

Change can only be made by government leaders, the majority who are self centred.

[cynthiatheresasuzara]

If we want CHANGE, each one of us has to start changing first because we can’t change others.

[HedgehogInTheCPP]

Thank you, it's essential talk, it's not new data, but the massive impact of the people's knowledge about the climate and biodiversity crisis.

Some on this site have stated wrongly that extinctions are actually declining since 1900. This is not true. It can easily be fact-checked. Here is a quote from the Royal Society as one example: One of the largest effects of humans on the natural world has been to raise the rate of extinction of species far above natural levels. This began many thousands of years ago, and as a result the human-caused loss of global biodiversity was already significant before the modern era. Now, the extinction rate is accelerating, biodiversity is in rapid decline, and many ecosystem processes are being degraded or lost.

The likelihood of the entire human population having this paradigm shift is perhaps very close to zero, at least in the time left to do it. With this in mind, why are we not talking about what would happen if we don’t shift our ways in time? What are the real world scenarios of climate refugees, sea level rise, food production interruptions through climate stresses, what food will our children be eating and will they be fighting each other for it? Will the countries with the biggest sticks take control of global food production by force, will nut jobs try and reduce the population through bio-weaponry, or will others push nuke buttons? We need to be honest here, everyone alive today has only known Goldilocks living conditions and if these shift substantially, as I believe tipping points may effect, then we need to have plans and skills taught to the young to manage it (how to fix things, grow things, repurpose things, communicate new ideas without fear, self defence, regional defence, health knowledge, working as small communities in contact with each other sharing new knowledge.

70 years warning, nothing ever changed

[knallhardt]

Dear Prof Rockström. Iam always impressed by your speeches. I would love to meet you. But today presentation and please Iam sorry for my words, but today Iam feeling like I have to puke and cry in the same time. What can a single person, a father, a husband do to change our Path of humanity? What can we do? Iam so scared and Iam a scientist, a geographer for climaterisk. Looking forward to your answer.

[patricialongo]

While the animals were being decimated, while they were killed my family ridiculed and tortured me when I tried to talk about it. They're Americans. Happy, successful and far more popular than I am, capable of decking me, their sister, for talking.

[pokemonjodeldodel]

its been 50 years of explaining. now change something!

[felixsandstrom]

I want him to show some graph where it clearly show how much more extreme weather we have today relative to the beginning of industrial revolution. That would be interesting to see. How much higher hurricane frequency, how much higher intensity, how much more droughts, how much stronger heatwaves etc.

[RickLarsonPermacultureDesigner]

Also, nature is a path for humans to walk with for a satisfying healthy life.

[ChristopherLecky]

Humanity's current level of influence on the planet represents a fundamentally new variable, one that has no precise historical precedent in Earth's long history. While natural cycles like ice ages, tectonic shifts, and even volcanic events have shaped the Earth for billions of years, the scale and speed at which humans are impacting the environment are unparalleled.
The only thing we should be doing given that this is the case is empowering those able to reimagine humanities existence on earth rather than looking to keep things as similar to todays arrangement as is humanly possible, , , , if those gripping on to humanity to harvest the spending potential of our species do not let go, the window of opportunity we have to utilise the creative variation and potential of our population will vanish in order to maintain the advantages of a

We simply need to evolve as a species and come together as a common humanity fighting for survival; we can do this as easily as I can write it!
