Considering cryosphere and warming uncertainties together implies drastically increased risk of threshold crossing in the cryosphere, even under lower-emission pathways, and underscores the need to halve emissions by 2030 in line with the 1.5 °C limit of the Paris Agreement.
Overcoming global inequality is critical for land-based mitigation in line with the Paris AgreementPeer reviewed
This report finds that overcoming global inequality is critical for land-based mitigation in line with the Paris Agreement. We show that if sustainable development in the land sector remained highly unequal and limited to high-income countries only, global agriculture, forestry and other land use emissions would remain substantial throughout the 21st century.
No time for complacency: without closing the 2030 gap, net zero targets cannot prevent severe climate impactsBriefing papers
The Glasgow Climate Pact doubled down on the commitment from 197 countries to limit global warming to 1.5°C, but current 2030 targets are insufficient to get us there. Instead, they would lead to 2.4°C of warming by the end of the 21st century.
The contributions of single greenhouse gas emitters to country-level climate change are generally not disentangled, despite their relevance for climate policy and litigation. Here, we quantify the contributions of the five largest emitters (China, US, EU-27, India, and Russia) to projected 2030 country-level warming and extreme hot years with respect to pre-industrial climate using an innovative suite of Earth System Model emulators.
