Trends and drivers in global surface ocean pH over the past 3 decades

We report global long-term trends in surface ocean pH using a new pH data set computed by combining fCO2 observations from the Surface Ocean CO2 Atlas (SOCAT) version 2 with surface alkalinity estimates based on temperature and salinity. Trends were determined over the periods 1981–2011 and 1991–2011 for a set of 17 biomes using a weighted linear least squares method. We observe significant dec...

Rectal cancer: progress over the past two decades.

Changes in Earth's reflectance over the past two decades.

We correlate an overlapping period of earthshine measurements of Earth's reflectance (from 1999 through mid-2001) with satellite observations of global cloud properties to construct from the latter a proxy measure of Earth's global shortwave reflectance. This proxy shows a steady decrease in Earth's reflectance from 1984 to 2000, with a strong climatologically significant drop after 1995. From ...

Childhood leprosy in India over the past two decades.

OBJECTIVES Clinico-epidemiological pattern of childhood leprosy in India over the past two decades were analysed from the Indian studies conducted during the years 1990-2009. RESULTS Twelve studies on childhood leprosy were included. Ten were conducted in health institutions and one was a community-based survey. Voluntary reporting was the principal method of case detection; community survey ...
