Yes. Earth’s climate is warming, and the primary cause since the mid‑20th century is human activity—mainly the buildup of heat‑trapping gases from burning fossil fuels, deforestation, and some industrial processes. Key evidence: - Global temperatures: About 1.1–1.3°C warmer than late 1800s; the last decade was the warmest on record. - Ocean heat and sea level: Oceans are absorbing most excess hea

Yes. Climate change is real and primarily caused by human activities, especially burning fossil fuels and deforestation. Key evidence: - Temperature: Earth has warmed about 1.2°C since the late 1800s; the last decade was the warmest on record. - Greenhouse gases: CO2 rose from ~280 ppm preindustrial to over 420 ppm today; its isotopic “fingerprint” and falling atmospheric oxygen show it’s from fo

Yes. The planet is warming and the dominant cause is human activities—mainly burning fossil fuels, deforestation, and certain industrial and agricultural practices that raise greenhouse-gas levels. Key evidence: - Global average temperature has risen by about 1.1–1.3°C since the late 1800s. - Oceans are storing record amounts of heat; sea level has risen ~20–25 cm since 1900 and is accelerating.

Yes. Climate change is real, and the dominant cause of the current warming is human emissions of greenhouse gases, especially CO2 from burning fossil fuels and land-use change. Key evidence: - Global temperature: Earth has warmed about 1.2°C since the late 1800s; the past decade has been the warmest on record. - Greenhouse gases: CO2 has risen from ~280 ppm preindustrial to over 420 ppm today.

Yes. Climate change is real, and the evidence is overwhelming. The planet has warmed by about 1.2–1.3°C since the late 1800s, and the primary cause is human activity—mainly the burning of fossil fuels and deforestation, which increase heat‑trapping greenhouse gases. Key evidence: - Greenhouse gases: CO2 has risen from ~280 ppm preindustrial to over 420 ppm today. - Temperatures: Each of the past

Yes. The climate is warming and the primary cause is human activities, especially the burning of fossil fuels and deforestation. Key evidence: - Global temperatures have risen by about 1.1–1.3°C since the late 1800s; recent years are the hottest on record. - Atmospheric CO2 is ~420 ppm (up from ~280 ppm preindustrial), with a fossil-fuel isotope signature and well-understood heat-trapping physics
