Scientists warn 1.5°C climate change threshold could arrive by 2029
Summary
Global warming could pass the Paris Agreement’s 1.5°C threshold as soon as 2029, according to the EU’s Copernicus climate service. Current climate policies still point to substantial warming by 2100, while scientists say greenhouse gas emissions and continued fossil fuel development are driving the trend.Key Facts
- Copernicus projected that global warming could exceed 1.5°C above preindustrial levels by 2029, earlier than the estimate made when the Paris Agreement was adopted in 2015.
- Climate Action Tracker estimated that current policies could lead to nearly 5°F of warming by 2100.
- Even if existing policies and pledges are fully implemented, one estimate puts warming at 3.4°F above preindustrial levels by 2100.
- Copernicus said human-caused greenhouse gas emissions remain the main driver of rising global temperatures.
- Climate policy analysts said new oil and gas projects and weakened or delayed climate policies are hindering efforts to cut emissions.
- The conference co-hosts, Turkey and Australia, had opposed adding the word “clean” to proposed electrification targets.
- Australia is a major coal exporter, while Turkey relies heavily on coal for electricity.
