NIST Issues New Standard Reference Materials to Ensure Accurate Measurements of Greenhouse Gases

When it comes to tallying emissions of greenhouse gases, there is no better substitute than directly measuring the atmosphere. But this important accounting can be obscured, and even confused, if measurements of the air-borne heat-trapping chemicals are inaccurate or can’t be compared from one instrument or data set to the next.

Multi-Year Droughts Significantly Alter Structure, Composition, and Dynamics of Second-Growth Tropical Forests

New research suggests that multi-year droughts will significantly alter the structure, composition, and dynamics of second-growth tropical forests, which have re-grown after cessation of agricultural activity or a major disturbance such as fire. These second-growth forests represent the prevalent tropical forest cover today.

New Method to Project Future Climate Scenarios at Local Level

Global climate models are essential for climate prediction and assessing the impacts of climate change across large areas, but a Dartmouth College-led team has developed a new method to project future climate scenarios at the local level.

Biologists Develop New Method for Measuring Ecosystem Sensitivity to Climate Variability

By developing this method, the international team of researchers has been able to map which areas are most sensitive to climate variability across the world.

UCLA Researcher Reveals Impact of Long-Term Ozone Exposure

Adults with long-term exposure to ozone face an increased risk of dying from respiratory and cardiovascular diseases, a new study suggests.

Research Demonstrates Impact of Climate Change on Treatment & Prevention of Parasite Infections

New research demonstrates how climate change and the immune reaction of the infected individual can affect the long-term and seasonal dynamics of parasite infections. The study, led by Penn State scientists, assessed the infection dynamics of two species of soil-transmitted parasites in a population of rabbits in Scotland every month for 23 years.

Cloud Droplets Play Key Role in Atmospheric Transformation of Volatile Organic Pollutants

In addition to precipitation, clouds influence the climate in various ways: they cover 70% of the Earth's surface and represent nearly 15% of the volume of the atmosphere. Scientists need to understand their underlying chemical and physical mechanisms in order to better integrate them into climate change models.

New Findings Reveal Major Northward Expansion of Marine Mammal Exposure to Toxins

Toxins from harmful algae are present in Alaskan marine food webs in high enough concentrations to be detected in marine mammals such as whales, walruses, sea lions, seals, porpoises and sea otters, according to new research from NOAA and its federal, state, local and academic partners.

Newly Developed Dynamic Model Focuses on Site Scale Conservation

Knowing how climate change may affect an entire region is only marginally useful to land managers trying to preserve the small white lady’s slipper, a once-abundant orchid that today is found in small “postage stamp” prairie fragments as little as 10 acres in size in Minnesota and another dozen states across the Midwest. Land managers need the details: how might a small fragment of orchid habitat change with climate change, and what climate adaptation strategies will be most effective in preserving remaining populations of small white lady’s slipper?

Study Shows Increasing Water on Land Affects Rate of Sea Level Rise

New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise.
