Ocean Acidification Study uses pSense CO2 Meter

Ocean Acidification Study uses pSense CO2 Meter
How do you measure the effects of fossil fuel CO2 emissions on pH levels in oceans? That question was asked by in a paper presented at the American Institute of Chemical Engineers (AIChE) 2018 Spring Meeting and 14th Global Congress on Process Safety.

Haney Test Uses CO2 Sensor to Measure Soil Health

Haney Test Uses CO2 Sensor to Measure Soil Health
What’s the difference between poor and healthy soil? As early as 6,000 BC farmers understood the concept of alternating crops to improve soil conditions.

Southern hemisphere joins north in breaching carbon dioxide milestone

By Paul Krummel, Research Group Leader, and Paul Fraser, Honorary Fellow, CSIRO. Reprinted by permission. As we predicted last year, the background atmospheric carbon dioxide levels measured at Cape Grim on Tasmania’s northwest coast have officially passed the 400 parts per million (ppm) mark. Our measurements, compiled by our team at CSIRO together with the Bureau of Meteorology, show that the milestone was reached on May 10. In the past few days, the 400 ppm level has also been breached in Antarctica, where CSIRO’s measurements at Casey Station show the 400 ppm level was exceeded on May 14. Together, these...

Can CO2 influence plant transpiration and biodiversity?

Guest post by Michael Forster, Edaphic Scientific Pty Ltd Everyone knows that plants need carbon dioxide to grow. But fewer people know that carbon dioxide can also effect plant transpiration and even the water balance of entire ecosystems and catchments. Even fewer people know that carbon dioxide can affect biodiversity and which plant species are more common than other species. Let’s just leave aside all of the topics on how increasing carbon dioxide is leading to global warming and how this, in turn, is impacting on plant species. Let’s just focus purely on how increasing atmospheric carbon dioxide changes the...

EPA Plans to Cut CO2 from Power Plants in US

The U.S. Environmental Protection Agency has released the Clean Power Plan proposal, which is designed to cut carbon dioxide pollution from existing power plants. Older power plants are some of the largest single-sources of CO2 emission in the United States. The goal of the proposal is to, “protect public health, move the United States toward a cleaner environment and fight climate change while supplying Americans with reliable and affordable power,” according to information supplied by the EPA. The Clean Power Plan will be implemented through a state-federal partnership under which states identify a path forward using either current or new...
