Year-to-year variations in climate, including rainfall and the length of the growing season, remain the greatest determinant of agricultural productivity and the cost of food.
Let’s have less hot air, more clean air.
Globally, air pollution is estimated to cause 3.3 million premature deaths each year.
Phosphorus futures
When it’s gone, it will be very difficult to supply phosphorus to crops without major expense, and there is no substitute.
Sugarbush
Maple sugaring, which dates back to the indigenous peoples of North America, is an elegant mix of biology, physics, and patience.
Our experience with solar
You can join the movement now, or wait until the panels are even more efficient and cheaper in just a few years. Either way, you will want renewable energy in your future.
Melting at the bottom of the Earth
Some of the ice sheets lost in Antarctica have been stable for up to 10,000 years; their loss is indicative of a new set of conditions, likely due to human activity.
Clathrates
Global warming may beget drastically more global warming, if we ever destabilize the pool of methane clathrates that are buried in polar regions.

Designer Ecosystems
Global survey of restoration projects found only 25% of the ecosystem services provided by nature were found in the restored systems.
