2 verifications about Fossil Fuels Fossil Fuels ×
“Human activities, especially burning fossil fuels and land-use change such as deforestation, are altering the global carbon cycle by increasing atmospheric carbon dioxide concentrations.”
The evidence firmly supports this statement. Multiple authoritative scientific assessments and direct atmospheric measurements show that burning fossil fuels and land-use change have raised atmospheric CO2 and altered the global carbon cycle. Natural sources of CO2 exist, but they do not explain the sustained modern increase, which is attributable to net human emissions.
“As of March 1, 2026, renewable energy sources are more expensive per kilowatt-hour than fossil fuels in most major economies.”
This claim is false. As of early 2026, authoritative data from IRENA, BloombergNEF, and Lazard consistently show that renewable energy — particularly onshore wind (~$0.034/kWh) and solar PV (~$0.043/kWh) — is cheaper per kilowatt-hour than fossil fuels ($0.08–$0.17/kWh) for new electricity generation in most major economies. IRENA reports that 91% of newly commissioned utility-scale renewable projects undercut the cheapest fossil fuel alternatives. The claim inverts the actual cost relationship.
