Earth 2.0(°C)

MANY HIGHLY VULNERABLE POPULAtions and ecosystems are already facing the devastating impacts of climate change.

- WILLIAM SOLECKI

While COP 28 last year provided glimmers of hope that countries can meaningfully respond, it is increasingly clear that the rise in global temperature will exceed the 1.5°C threshold defined in the 2015 Paris Agreement. Already, we are at 1.15°C of heating above the 19th century baseline and will likely pass 1.5°C in the mid-2030s. The window to forestall this event is closing, because of barriers including lack of financing, institutional capacity, and such factors as poverty, consumption, and lack of societal trust. It's time to prepare to get closer to a 2.0°C warmer world.

Several opportunities for meaningful action lie well within our grasp. We must collectively work toward climate-resilient development-simultaneously adapting to climate risks and incentivizing opportunities to reduce greenhouse-gas emissions. Together, these two aims could tackle climate change while promoting sustainable and equitable economic advancement. Whether it is industries and employees retooling for a green economy, or communities fearing loss of their neighborhood to flooding or climate gentrification, the evidence is overwhelming that the more equitable and engaged the decision-making process, the more likely the climate action will succeed.
