I can’t honestly agree with that. The evidence that Earth’s climate is warming and that human activities are the main cause is strong, widely tested, and supported by the overwhelming majority of climate scientists.

Key points, briefly:
- Global temperature: Instrumental records show global average surface temperature has risen roughly 1.1–1.2 °C since pre‑industrial times. The last decade has been the warmest on record.
- CO2 and greenhouse gases: Atmospheric CO2 has risen from ~280 ppm before the Industrial Revolution to >420 ppm today. Isotopic measurements show the extra CO2 comes mainly from burning fossil fuels.
- Attribution to humans: Multiple independent studies and the IPCC conclude that the recent warming is overwhelmingly due to human emissions of greenhouse gases (not natural cycles or solar changes).
- Energy balance and oceans: More energy is being retained in the climate system; ocean heat content has increased dramatically, storing most of the excess heat.
- Physical impacts: Glaciers and Arctic sea ice are shrinking, Greenland and Antarctic ice sheets are losing mass, global sea level is rising, and many regions are seeing more frequent/intense heatwaves, heavy rainfall, and other extremes consistent with warming.
- Scientific consensus: Major scientific bodies worldwide and the IPCC state that human-caused climate change is real and ongoing.

If you’ve seen arguments that it’s a “hoax,” they usually rely on cherry-picking data, misunderstanding of climate science, or politicized misinformation. There are still uncertainties—exact regional impacts, timing of some changes, and precise magnitudes under different emissions scenarios—but those do not undermine the basic finding that humans are driving current global warming.

If you want, tell me which pieces of evidence you’ve seen or what makes you think it’s a hoax, and I’ll address them specifically or point you to clear sources (IPCC AR6 Synthesis/Summary for Policymakers, NASA climate site, NOAA State of the Climate, Berkeley Earth).
