The warmest 200-year-long interval took place around 6500 years ago when GMST was 0.7 °C (0.3, 1.8) warmer than the 19th Century (median, 5th, 95th percentiles). Following the Holocene global thermal maximum, GMST cooled at an average rate −0.08 °C per 1000 years (−0.24, −0.05).

Without humans, we'd be cooling, not warming.

We've literally cancel the next Ice Age for 50,000-100,000 yr.

As for solar activity? The recent upswing in flares and sunspots is unrelated to modern temperature spikes. How do we know this? Because recent activity is actually weaker than previous cycles. Blaming the Sun is a long-discredited linchpin of climate change denial.
