"Houses were shut tight, and cloth wedged around doors and windows, but
the dust came in so thinly that it could not be seen in the air, and it settled like
pollen on the chairs and tables, on the dishes.” – Grapes of Wrath
77. KEY POINTS
Climate change effects have already emerged in New Jersey.
Supporting improvements to observations and climate models will
reduce uncertainty in future climate projections.
We can still prevent the worst of the impacts globally.
