Impact of greenhouse gases on global temperature and weather patterns.
The Shared Socioeconomic Pathways (SSPs) are a set of five global scenarios (SSP1–SSP5) used in climate research to describe alternative socioeconomic futures through 2100.…
Sea-level rise is not uniform across the globe due to a combination of factors including gravitational effects from melting ice sheets, ocean currents and…
Sea-level rise is driven by two main processes: thermal expansion of seawater as it warms, and the addition of freshwater from melting land ice.…
Gross zero emissions means eliminating all greenhouse gas emissions at their source, while net zero allows for some residual emissions to be balanced by…
Avoidance credits finance projects that prevent emissions, while removal credits support projects that extract CO2 from the atmosphere. Both are used in carbon markets…
Methane is a potent greenhouse gas that traps heat far more effectively than carbon dioxide but remains in the atmosphere for only about 12…
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…
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,…
A 2014 study in Nature found that rising atmospheric CO₂ levels reduce the protein, iron, and zinc content of staple crops like wheat, rice,…
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…
