Mediante el estudio de sedimentos de lagos africanos de los últimos 20,000 años, los científicos están aprendiendo más sobre los cambios climáticos abruptos, obteniendo una mayor comprensión de los cambios del clima.

En un artículo reciente publicado en la revista Nature Geoscience, el profesor Nicholas McKay analiza muestras del núcleo del lago Bosumtwi en Ghana. El lago fue formado por un meteorito y luce como un cuenco en el paisaje dando a los científicos una visión clara de los cambios ambientales.

The financial cost of the diseases of modern civilization is almost double the budget of the National Health Service, writes Jules Pretty, while the economy has grown past the point of greatest satisfaction. Our over-riding priority should be to move to greener, healthier, more sustainable and satisfying ways of life.

A substantial financial dividend could be released by a greener and healthier economy. Instead of encouraging material growth and consumption, we should consume in a way that is environmentally sustainable.

By studying African lake sediments from the past 20,000 years, scientists are learning more about abrupt climate shifts, advancing their understanding of changing weather patterns. In a recent paper published in Nature Geoscience, co-author on an NAU assistant professor Nicholas McKay analyzes core samples from Lake Bosumtwi in Ghana. The isolated lake was formed by a meteor and sits like a bowl on the landscape giving scientists a clear view of environmental changes.

The Center for Biological Diversity this week launched its new Environmental Health program, greatly expanding its capacity to protect wildlife, people and the environment from pesticides, rodenticides, lead, mining, industrial pollution, and air and water pollution.

“The future of people is deeply intertwined with the fate of all the other species that evolved beside us,” said Lori Ann Burd, the program’s director. “This new program will work to protect biodiversity and human health from toxic substances while promoting a deep understanding of the connection between the health of people and imperiled species.”

The day I first set foot in a tropical rainforest, in Malaysia in the early 1980s, I experienced something profound. From the echoes of gibbons calling from the canopy in the early morning mist to the iridescent flash of a bird in a beam of sunlight, rainforests are a sensory delight as well as a marvel to anyone’s scientific curiosity. 

As I subsequently watched these forests dwindle and, in some cases, vanish, I have felt an equally profound sense of loss and a nagging guilt that I was somehow part of the story, because I had done little to remedy the situation.
