Natural cycles exist—but cannot explain the observed rate or magnitude of modern warming. Physics-based attribution studies show the current energy imbalance aligns with greenhouse gas forcing, not orbital or solar changes.
CO₂’s radiative importance depends on infrared absorption, not concentration alone. Even trace gases can dominate radiative forcing when they absorb in otherwise transparent atmospheric windows.
Models are testable physical frameworks. While imperfect, they reproduce large-scale energy balance and trends verified by satellite and surface observations. Their uncertainties are quantifiable, not disqualifying.
Multiple independent studies find over 97 % of climate scientists agree that human activity is warming the planet. Apparent “debate” often arises from misrepresentation or non-expert amplification.
Past climate changes were driven by orbital, volcanic, and solar variations acting over millennia. Today’s rapid shift—occurring within decades—matches the fingerprint of anthropogenic greenhouse forcing.
Weather and climate operate on different scales. Local cold events do not negate global trends; in fact, a warmer atmosphere can amplify extreme patterns by altering jet-stream dynamics and moisture availability.
