Australia drying caused by greenhouse gases and ozone
NOAA scientists have developed a new high-resolution climate model that shows southwestern Australia's long-term decline in fall and winter rainfall is caused by increases in manmade greenhouse gas emissions ...
Researchers pinpoint massive harmful algal bloom
The bloom that began earlier this year and shut down several shellfish fisheries along the West Coast has grown into the largest and most severe in at least a decade.
Using new data, US finds no pause in global warming
Using updated data on the Earth's surface temperatures worldwide, US government scientists have found no evidence of a pause in global warming in recent years, according to research published on Thursday.
Global carbon dioxide levels reach new monthly record (Update)

New method efficiently estimates surface reflectivity from incoming sunlight bounced back by clouds
Capturing sunlight reflected off the Earth's surface and bounced off a cloud back to the Earth is an effective measure of surface reflectivity—or surface albedo, the measure of how mirror-like the Earth's ...
New research explains wintertime ozone pollution in Utah oil and gas fields
Chemicals released into the air by oil and gas exploration, extraction and related activities can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards, ...
