| Author’s Note: This is a typical graphic used in meteorology and hydrology. The individual years are shown but may be difficult to see as they are faint but the average of the prior 50 years is clearly visible. The blue line shows this year to date (February 15, 2024). It is clearly unusual. Is it unusual enough to conclude that it is outside of the range of Post Industrial Revolution Climate? I do not know. If this pattern shows up a few more times some will draw that conclusion. And for sure the winter is not yet over and I think it is snowing there right now. Whether it is cold enough for ice to form I do not know. Since we are comparing the current to a 50 year average, I have categorized this as climate rather than weather but others may see it differently. |
