**1. Summary of the results** The scientific evidence overwhelmingly supports that climate change is caused by human activity. Multiple independent analyses present a clear consensus: * 97% of climate scientists agree that human-caused climate change is real ^[1] * By March 2023, the IPCC concluded that human activities have "unequivocally caused global warming" ^[1] * A 2019 analysis found 100% agreement among scientists on anthropogenic global warming ^[2] * Earth's average surface temperature has risen by approximately 1.8°F since 1880 ^{[3] [3]} * Carbon dioxide levels have increased dramatically from 280 to 410 parts per million ^{[3] [3]} **2. Missing context/alternative viewpoints** The original question lacks several crucial pieces of context: * The rate of change is unprecedented - current CO2 increases are happening 250 times faster than natural sources after the last Ice Age ^[4] * The evidence isn't just about temperature - it includes multiple indicators: * Ocean warming * Ice sheet loss * Rising sea levels ^[4] * Changes in bird migration patterns * Glacier melting ^[3] * Scientists can identify the source of CO2 through isotopic "fingerprinting," which confirms it comes from fossil fuels rather than natural sources ^[3] * The scientific confidence in human-caused climate change equals that in the theory of gravity ^[2] **3. Potential misinformation/bias in the original statement** The original question's simplicity could lead to several misconceptions: * It might suggest there's still significant scientific debate about the cause, when in fact there isn't - the consensus is overwhelming ^{[1] [2]} * It doesn't acknowledge that natural climate variations have been ruled out as explanations for current trends ^{[1] [5]} * The question might imply this is a political rather than scientific issue Those who benefit from questioning human involvement in climate change often include: * Fossil fuel industries * Companies with significant carbon-intensive operations * Political entities aligned with these industries Meanwhile, those supporting the scientific consensus include: * The global scientific community, represented by the IPCC ^[1] * Independent experts like Andrew Dessler and Howard Diamond ^[6] * International scientific organizations and research institutions
