If a large hurricane struck NYC, should we immediately blame CO2?

From World Climate Report here:

The pair of geologists was able to reconstruct storm surge levels in the New York City area, and as seen in Figure 1, largest surges are found in 1788, 1821, and 1893. Maybe it is just us at World Climate Report, but we fail to see any trend upward coincident with the buildup of greenhouse gases. Furthermore, we notice that the three large surges occurred during a time when, last we checked, the Northern Hemisphere was considerably cooler than what we have today.
