Avoidance Credits vs Removal Credits: A Comparative Analysis of Carbon Market Instruments
Avoidance credits finance projects that prevent emissions, while removal credits support projects that extract CO2 from the atmosphere. Both are used in carbon markets…
Why Methane Causes Strong but Shorter-Lived Warming
Methane is a potent greenhouse gas that traps heat far more effectively than carbon dioxide but remains in the atmosphere for only about 12…
Per-Capita vs Total Environmental Impact: The Case of Global CO2 Emissions
In 2022, global total CO2 emissions from fossil fuels and industry reached 36.6 GtCO2, while per-capita emissions stood at 4.7 tCO2 per person, according…
Projected Global Warming by 2100 Under Current Policies: Insights from Integrated Assessment Models
According to the UNEP Emissions Gap Report 2023, integrated assessment models (IAMs) project a median global warming of 2.8°C by 2100 under current policies,…
Increasing CO₂ threatens human nutrition
A 2014 study in Nature found that rising atmospheric CO₂ levels reduce the protein, iron, and zinc content of staple crops like wheat, rice,…
Downscaling Climate Data: Statistical vs Dynamical Methods – Current State and Trends
As of 2024, dynamical downscaling achieves resolutions as fine as 1–3 km, while statistical downscaling provides point-scale projections; both methods are essential for local…
Climate Change Explained: Causes, Evidence, Impacts and Solutions
A complete guide to climate change, including causes, scientific evidence, impacts, adaptation, mitigation, carbon cycles, and practical climate solutions.
Climate Mitigation vs Climate Adaptation: Understanding the Two Pillars of Climate Action
Climate mitigation and climate adaptation are two complementary strategies for addressing climate change. Mitigation focuses on reducing greenhouse gas emissions to slow global warming,…
CO₂ vs CO₂-Equivalent: Understanding Greenhouse Gas Metrics
As of 2023, global CO₂ emissions from fossil fuels and industry reached approximately 36.8 billion tonnes (GtCO₂), while total greenhouse gas emissions expressed in…
