Climate change could bring sudden drought to La Paz

As the world warms, scientists expect some ecosystems to gradually migrate up slopes, essentially chasing environmental conditions they need to thrive.

But according to recent research on the historical ecology of the Andes conducted in part by a Westfield State University assistant professor, those steady changes can reach a tipping point in some cases that flips local ecosystems on their head.

The scientists examined fossilized pollen in Lake Titicaca, the world’s highest elevation great lake on the border of Peru and Bolivia, which allowed them to look 370,000 years back in time. They found that in two periods of past warming, the lake shrank by as much as 85 percent, and switched the grassland ecosystem into desert.

High Lead Levels Found in Urban Gardens

Researchers from Wellesley College have found that urban vegetable gardeners can be exposed to lead contamination even if they use raised beds with clean compost or topsoil. It isn’t the vegetables but the dirt itself that can collect fine lead particles. The lead, from industrial site around the city, can sometimes become airborne and lands in urban gardens, Daniel Brabander and his team of researcher found. The group presented their findings at the 2010 annual meeting of the Geological Society of America.

Debate Over Turning a Sea Salt Operation into Smart Growth Development

A 1,436 acre sea salt operation south of San Francisco Bay may be the future site of a smart growth development. The natural evaporation ponds, located in Redwood City, have been in production since 1901. Cargill, who owns the operation, plans to develop this area with the help of Arizona developer DMB Associates. The development will be promoted as a “50/50 balance plan,” a community of 8,000 to 12,000 low-rise, energy efficient apartments, schools, offices, and retail space, mixed with open space and restored wetlands.
