Are humans responsible for climate change?

I will check the latest scientific consensus from authoritative sources.I am fetching a couple of key primary pages for precise statements.Yes, humans are the primary cause of recent climate change (global warming since the Industrial Revolution/pre-industrial period). This is the overwhelming scientific consensus, supported by multiple independent lines of evidence from observations, paleoclimate records, basic physics, isotopic analysis, and climate models.[1]

Scientific Consensus

Key Evidence

1. Rising greenhouse gases from human activities
Burning fossil fuels (coal, oil, gas), deforestation, agriculture, and industry have sharply increased atmospheric CO₂ (from ~280 ppm pre-industrial to over 410–420 ppm recently), methane, and N₂O. These gases trap heat (the enhanced greenhouse effect). Isotopic “fingerprints” (e.g., the ratio of carbon isotopes) confirm the extra CO₂ comes primarily from fossil fuels, not natural sources like volcanoes or the ocean. Concentrations are higher than at any time in at least the last 800,000 years.[4]

2. Climate models and attribution studies (“fingerprints”)
Models that include only natural factors (solar variability, volcanoes, orbital cycles) cannot reproduce the observed rapid warming of the past ~150 years—especially since the mid-20th century. Models that include human greenhouse gas emissions match the observations closely. Human “fingerprints” appear in many parts of the climate system: tropospheric warming + stratospheric cooling, ocean heat content rise and acidification, Arctic sea ice and glacier loss, sea-level rise, changes in precipitation patterns, and more.[5]

3. Rate and pattern of change
The current warming rate is unprecedented in at least the last 2,000 years (and much longer in many reconstructions). Paleoclimate data (ice cores, tree rings, sediments) show past natural changes were slower and driven by different mechanisms. Solar output has been stable or slightly declining in recent decades while temperatures rose; if the Sun were responsible, the upper atmosphere would warm too—but it is cooling.[6]

4. Basic physics
The greenhouse effect has been understood since the 19th century (Fourier, Tyndall, Arrhenius). Adding heat-trapping gases must warm the surface unless offset by an equally large cooling force—which has not occurred.

Natural climate variability and forcings still exist and influence year-to-year or decade-to-decade weather/climate (e.g., El Niño, volcanic eruptions), but they do not explain the long-term global warming trend. Earth’s climate has always changed, but the current rapid change is overwhelmingly anthropogenic.

In short: the evidence is robust, multi-faceted, and has strengthened over decades of research. Leading scientific bodies treat human responsibility for recent climate change as established fact.
