…it is a point along a continuum that we know leads to ever-worse consequences, with potentially irreversible impacts on water resources, biodiversity, ecosystems, and other key aspects of our planet’s functioning. And, as always, impacts on humans will be worst for those with the least capacity to deal with changes.
Hitting 400ppm also reminds us of the failure of the international community to reach an agreement that would permanently bend the emissions curve in the right direction. … Of course, we need to respect the complexity of the negotiations; after all, it involves the core of our development, including tomorrow’s energy systems, our consumption patterns, global trade and other fundamental aspects of our societies and lives. Still, this new CO2 record should add to the sense of urgency – making it clear that climate systems cannot be put on hold while we make a new agreement.
