What are the long-term implications of these record CO2 levels, and what actions are needed to address them?

The sustained rise in atmospheric CO2, exceeding 430 ppm, will likely exacerbate existing climate challenges, including more frequent and intense heatwaves, droughts, and extreme weather. The long atmospheric lifetime of CO2 means these effects will persist for millennia, necessitating immediate global action to mitigate further increases and adapt to unavoidable changes. The impact on marine life from ocean acidification will also continue to worsen.

What are the immediate and specific impacts of the record-high atmospheric CO2 levels in 2024?

Human activities, primarily fossil fuel use since the 1800s, have released over 1.5 trillion tons of CO2 into the atmosphere, exceeding the planet's natural absorption capacity. This surplus is causing a rapid increase in global temperatures and ocean acidification, harming marine life and ecosystems. The consequences include more frequent and intense extreme weather events and rising sea levels.

How does Rohling's research on ocean warming and thermohaline circulation explain the inertia of the climate system and its response to emission reductions?

Rohling's work connects past climate data to future projections, highlighting the inertia of the climate system. He uses the analogy of a freight train to explain slow responses to emission changes, emphasizing that deep-sea warming, driven by thermohaline circulation, will prolong warming for centuries. This contrasts with IPCC models that haven't fully incorporated these long-term effects.
