Global Wave of Climate Action

15.000 scientists:

We are venturing into uncharted climate territory

20 of the 35 vital signs are now showing record extremes

Such anomalies may become more frequent and could have increasingly catastrophic impacts

Energy:

Fossil fuels remain dominant

Carbon emissions have continued soaring

Annual coal consumption reaching a near all-time high

Forests:

Global tree cover loss rate declined 9.7%

Humanity is not on track to end and reverse deforestation by 2030

Forests are increasingly threatened by powerful climate feedback loops

Global mean greenhouse gases and temperature:

CO2 is now at 420 ppm (Far above the save limit of 350 ppm)

Carbon dioxide, methane, and nitrous oxide—are all at record levels

2023 is on track to be one of the hottest years on record

Oceans and ice:

Ocean acidity, glacier thickness, and Greenland ice mass all fell to record lows

Sea level rise and ocean heat content rose to record highs

Atlantic meridional overturning circulation could pass a tipping point and start to collapse this century

Climate impacts and extreme weather:

Deadly flash floods in northern India

Record-breaking heat waves in the United States

Exceptionally intense Mediterranean storm that killed thousands of people

China experienced its heaviest rainfall in at least 140 years

Economics:

Economic growth, as it is conventionally pursued, is unlikely to allow us to achieve our social, climate, and biodiversity goals

Technological advancements often fall short in mitigating the overall ecological footprint of economic activities

Stopping warming: efforts must be directed toward

Eliminating emissions from fossil fuels and land-use change

Increasing carbon sequestration with nature-based climate solutions

We should not rely on unproven carbon removal techniques

Stopping coal consumption:

Global coal consumption is near record levels

Coal usage in China has accelerated rapidly in the past decades

Support the Powering Past Coal Alliance

Adoption of the international Coal Elimination Treaty

Food security and undernourishment:

Undernourishment is now on the rise

735 million people faced chronic hunger

Hunger could escalate in the absence of immediate climate action

Risks of synchronized harvest failures caused by increased waviness of the jet stream

Efforts are needed to improve crop resilience and resistance to heat, drought, and other climate stressors

A shift toward plant-based diets could improve global food security and help mitigate climate change

Justice:

Impacts of climate change are already catastrophic for many

They disproportionately affect the world's most impoverished individuals

Strive for a convergence in per capita resource and energy consumption

Conclusions:

The truth is that we are shocked by the ferocity of the extreme weather events in 2023

We are afraid of the uncharted territory that we have now entered

This is our moment to make a profound difference for all life on Earth

Possibilities such as a worldwide societal breakdown are feasible and dangerously underexplored

By 2100 an estimated 3 to 6 billion individuals might find themselves confined beyond the livable region

Climate emergency is systemic, existential threat

Challenge the prevailing notion of endless growth and overconsumption

Advocate for reducing resource overconsumption

Transformation of the global economy to prioritize human well-being

Every further 0.1°C increase in future global heating cannot be overstated

Rather than focusing only on carbon reduction and climate change, addressing the underlying issue of ecological overshoot will give us our best shot at surviving
