+  title: Sea ice sensitivity
+
+  description: |
+    Recipe for quantifying the sensitivity of sea ice to global warming.
+    Siconc data is summed for each hemisphere and then compared to the
+    change in globally meaned, annually meaned surface air temperature.
+    In the northern hemisphere, September sea ice data is used.
+    In the southern hemisphere, annual mean sea ice data is used.
+    Two plots are produced for each hemisphere, one showing the gradient
+    of the direct regression of sea ice area over temperature, and the
+    other showing the two separate trends over time.
