Mitigation implications of remaining carbon budget allocation rules for Mediterranean countries

The Mediterranean Basin is a climate change hotspot, experiencing accelerated warming and strong environmental vulnerability. Mediterranean Sea surface temperatures have increased by approximately 1.5 °C over the past four decades, underscoring the urgency of coordinated mitigation efforts. In this context, this study...

A scenario assessment of the global mitigation effort in the light of the 2035 climate finance goal

The United Nations Framework Convention on Climate Change (UNFCCC) agreed in 2024 to boost finance for climate change in developing countries to USD 300 billion by 2035. In this study, we assess how much mitigation of greenhouse gases (GHGs) is possible by generating this amount of revenues from carbon pricing in indus...

Establishing SI in space for climate action

The Earth is unequivocally warming with consensus mankind is the major cause. The potential for societal catastrophe is second to none!. The ‘Paris Agreement’ (2015) seeks to contain the rise in mean Earth temperature to <2°C above pre-industrial levels with a target of <1.5°C and led to the establishment of ‘NetZero’...

Analysis and Outlook on Actions to Address Climate Change in 2025

The World Meteorological Organization (WMO) has confirmed that 2024 was the warmest year on record. Global warming is moving increasingly closer to the [Formula: see text]C temperature limit set by the Paris Agreement. Against a background of global economic uncertainty and geopolitical instability, international effor...

Limiting warming by CO2 and methane mitigation in an expanded scenario space

Anthropogenic methane (CH4) currently contributes more than 0.6 ∘C to global warming, and CH4 mitigation is a powerful option to limit near-term warming. Assessments of greenhouse gas (GHG) mitigation rely on Integrated Assessment Model scenarios with typically non-linear emission trajectories (due to economic optimiza...
