Try this:
import seaborn as sns
import matplotlib.pyplot as plt
fig, axs = plt.subplots(ncols=1, nrows=2)
sns.kdeplot(data=avg_100_data, x="AVGT", ax=axs[0])
sns.kdeplot(data=avg_100_data, x="SE AVGT", ax=axs[1])
axs[0].set(xlabel="Average temperature estimates")
axs[1].set(xlabel="Average temperature SE")
plt.show()
