Cement manufacturing is among the most carbon-intensive industrial processes, but an international team of researchers has found that over time, the widely used building material reabsorbs much of the CO2 emitted when it was made.

It turns out bird poop helps cool the Arctic.

That’s according to new research from Colorado State University atmospheric scientists, who are working to better understand key components of Arctic climate systems.

If society continues to pump greenhouse gases into the atmosphere at the current rate, Americans later this century will have to endure, on average, about 15 daily maximum temperature records for every time that the mercury notches a record low, new research indicates.

That ratio of record highs to record lows could also turn out to be much higher if the pace of emissions increases and produces even more warming, according to the study led by scientists at the National Center for Atmospheric Research (NCAR).

Los estadounidenses desechan cerca de 12,8 millones de toneladas de productos textiles anualmente, es decir, casi 40 kilos por cada hombre, mujer y niño. En los Estados Unidos y en todo el mundo, un número creciente de ecologistas y directivos de la industria textil coinciden en que ha llegado el momento de poner fin a la cultura del desperdicio textil y están empezando a fabricar a gran escala nuevas prendas de vestir elaboradas con material usado.

In large parts of Europe and North America, the decline in industrial emissions over the past 20 years has reduced pollution of the atmosphere and in turn of soils and water in many natural areas. The fact that this positive development can also have negative implications for these regions has been demonstrated by scientists at the Helmholtz Centre for Environmental Research (UFZ) in the journal Global Change Biology. According to their findings, declining nitrate concentrations in the riparian soils surrounding the tributary streams of reservoirs are responsible for the increasing release of dissolved organic carbon (DOC) and phosphate and a deterioration in water quality. In the case of drinking water reservoirs this can cause considerable problems with respect to water treatment.
