Equilibrium climate sensitivity, the global surface temperature response to CO$_2$ doubling, has been persistently uncertain. Recent consensus places it likely within 1.5‐4.5K. Global climate models (GCMs), which attempt to represent all relevant physical processes, provide the most direct means of estimating climate sensitivity.

The 15th edition of the World Economic Forum’s Global Risks Report is published as critical risks are manifesting.

This publication assesses the potential of carbon dioxide-enhanced oil recovery (CO2-EOR) technology to mitigate climate change in Indonesia. Although the technology was designed to rejuvenate oil production in mature oilfields, its value in permanently storing CO2 has recently attracted global interest.

Since 2000, IOM has been producing world migration reports. The World Migration Report 2020, the tenth in the world migration report series, has been produced to contribute to increased understanding of migration throughout the world.

Transport-related emissions from tourism are expected to account for 5.3% of all anthropogenic emissions by 2030, up from 5% in 2016, according to a report published by the International Transport Forum (ITF) and the World Tourism Organization (UNWTO).
