The past helps us to understand the present and provide insights into the response of the Earth Systems to the increase in greenhouse gases. We study the natural dynamics of the atmosphere, oceans and continental ecosystems, and the global biogeochemical and hydrological cycles, during episodes of global warmth and extreme climates.
To limit the increase in global mean temperature to 1.5 °C, CO2 emissions must be drastically reduced. Accordingly, approximately 97%, 81%, and 71% of existing coal and conventional gas and oil resources, respectively, need to remain unburned. The UNBURNED project will develop the first global geospatial platform integrating policy-relevant information on fossil fuel reserves, state-level political indicators, biodiversity indicators, and social and economic indicators associated with fossil fuel divestment plans, impacts and activities. The platform will be presented in the COP29 next November and will propose sensitive areas that should remain entirely off-limits to fossil fuel extraction.
Tropical climates are changing rapidly in the most populated regions of the planet. The changes largely arise from alterations in the Hadley circulation driven by natural and anthropogenic factors, ...
