The Chinese Carbon-Neutral Goal: Challenges and Prospects.

On 22 September 2020, within the backdrop of the COVID-19 global pandemic, China announced its climate goal for peak carbon emissions before 2030 and to reach carbon neutrality before 2060. This carbon-neutral goal is generally considered to cover all anthropogenic greenhouse gases. The planning effort is now in full swing in China, but the pathway to decarbonization is unclear.

An Assessment of Earth's Climate Sensitivity Using Multiple Lines of Evidence.

We assess evidence relevant to Earth's equilibrium climate sensitivity per doubling of atmospheric CO, characterized by an effective sensitivity . This evidence includes feedback process understanding, the historical climate record, and the paleoclimate record. An value lower than 2 K is difficult to reconcile with any of the three lines of evidence.
