It will take a decade before these high recent carbon dioxide emissions will reach their full warming impact. Furthermore, as the world makes progress with the necessary cuts in greenhouse gas emissions, this will also remove aerosols that have until now masked the full wrath of global warming. By implication, without geoengineering occurring over the coming decade, temperatures will keep rising, resulting in further increases in abundance and intensity of droughts and wildfires.
Temperatures in the Arctic are rising faster than elsewhere. As increasing amounts of soot from wildfires settle on its ice and snow cover, albedo decline in the Arctic will accelerate. In addition, heatwaves are causing rapid warming of rivers ending in the Arctic Ocean, further speeding up its warming. Then, there's the huge danger of methane releases from the seafloor of the Arctic Ocean. Meanwhile, rising temperatures will also result in more water vapor in the atmosphere, further amplifying warming.
In conclusion, feedbacks are threatening to cause runaway warming, potentially making temperatures rise by more than 10°C or 18°F within a decade.
The situation is dire and calls for comprehensive and effective action as described in the Climate Plan.
