As Cyclones Move North, Glimmers of the Ancient Earth

September 24, 2022

Above, aftermath of Post-Tropical Cyclone Fiona in Nova Scotia. In a previous post, we heard Dr. Jason Box talk about Fiona’s path and how it will continue on to have impacts on the Greenland Ice sheet.

Below, I spoke to Paleoclimatologist Jeffrey Kiehl in 2015 at the American Geophysical Union Fall Meeting in San Francisco.
I was reminded of his remarks this week as we saw an outburst of tropical storms, Typhoon Merbok and Hurricane Fiona, strengthening and having severe impacts in regions well north of where we usually expect.

Yale Climate Connections:

Update (8 p.m. EDT): A suddenly dire situation has developed in the Northwest Pacific, where what was a tropical storm just a day earlier has explosively intensified into Super Typhoon Nori less than 18 hours before landfall. Nori is now predicted to strike the Philippines at category 5 intensity on Sunday night local time. See the end of this post for more details.

Post-tropical cyclone Fiona – the strongest storm in Canadian history, as measured by central pressure – crashed into the coast of eastern Nova Scotia early Saturday. More than 500,000 customers had lost power by midday Saturday according to, and countless trees have been brought down across wide stretches of Atlantic Canada. It’s too soon for a solid assessment of damage, but Fiona clearly gave several provinces their worst night of wind, water, and damage in decades, and perhaps in their modern history.

Especially hard hit were eastern stretches of the Cape Breton Peninsula, including Glace Bay, as well as Port aux Basques, on the southwestern tip of Newfoundland, which experienced a full-force hit from the front right-hand quadrant of Fiona. A number of coastal homes in Port aux Basques have been damaged or destroyed by storm-surge flooding, leading to an emergency evacuation order for the town on Saturday morning. Washed-out roads were making evacuation even tougher.

    With a common meme of denial being “that the climate is a;ways changing”, what really seems to be badly under appreciated is the rate at which it is changing.

    This is plain to see just looking at simple monthly data from the main scientific data providers. The fact we are getting glimpses of ancient Earth is not surprising, and is a glimpse of what might be increasingly more common in the near future.


    “The problem today is not higher global temperature or carbon dioxide levels alone. The problem is the rate of change,” explained Olsen. “Throughout most of the Earth’s history, carbon dioxide levels have generally changed very slowly. That gave organisms and their ecosystems sufficient time to adapt to climate change through both evolution and migration.”
