FAQ.
Climate change refers to significant, long-term changes in the Earth’s climate patterns, particularly the rise in global average temperatures due to human activities like burning fossil fuels, deforestation, and industrial processes.
Multiple independent datasets from NASA, NOAA, and the IPCC show a clear upward trend in global temperatures over the past century. In 2024, the global average temperature was 1.5 degrees Celsius above pre-industrial levels, marking the warmest year on record.
Greenhouse gases like carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) trap heat in the Earth’s atmosphere, causing the greenhouse effect. Human activities have significantly increased their concentrations, intensifying global warming.
Rising global temperatures cause polar ice melt and thermal expansion of seawater, leading to sea level rise. This threatens coastal communities with increased flooding and erosion.
Yes, climate change is increasing the frequency and intensity of extreme weather events such as heatwaves, hurricanes, and wildfires. In 2024, southern Europe experienced devastating wildfires due to record-breaking temperatures.
The primary drivers of climate change are human activities, including burning fossil fuels for energy, deforestation, industrial processes, and agricultural practices. These activities release large amounts of greenhouse gases into the atmosphere.
Climate change disrupts ecosystems, leading to habitat loss, altered migration patterns, and increased risk of extinction for many species. Tropical bird populations, for example, have declined by 25 to 38% since 1980 due to heat extremes.
Rising temperatures and extreme weather increase heat-related illnesses, respiratory problems, and vector-borne diseases. Extreme heat, for example, can raise the risk of newborn deaths by up to 22%.
The Paris Agreement is an international treaty adopted in 2015 by nearly 200 countries aiming to limit global warming to well below 2 degrees Celsius, preferably to 1.5 degrees Celsius, compared to pre-industrial levels. It focuses on reducing greenhouse gas emissions and enhancing climate resilience.
Individuals can reduce their carbon footprint by adopting sustainable practices such as using renewable energy, reducing waste, conserving water, supporting climate-friendly policies, and promoting reforestation efforts.
