Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.

That study provided estimates of vessel traffic (numbers of vessels and transits) based on modeling of current vessel activity patterns, growth potential, and vessel projection scenarios, including diversion from other routes, and oil and gas development. fuel for Arctic vessels assuming a low-growth scenario.

CSIRO publishes Southern Hemisphere GHG data online

Green Car Congress

For the first time, observed Southern Hemisphere greenhouse gas (GHG) data can be easily accessed by the public on a new CSIRO website. The atmospheric level of carbon dioxide, which is the most important long-lived greenhouse gas influenced by human activities, is at its highest level in more than a million years. per cent each year.

Climate Expert: Don't Call It Geoengineering

Cars That Think

In light of this situation, there's increasing talk of actions that governments can take beyond reducing greenhouse gas emissions—actions that could either remove existing greenhouse gases from the atmosphere or reduce the amount of sunlight coming into the atmosphere. Hardly the breakthroughs we need to stave off disaster.

Study finds global rivers and streams emitting 3x IPCC estimates of the GHG N2O

Green Car Congress

Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. It is produced via a microbial process called denitrification, which converts nitrogen to nitrous oxide and an inert gas called dinitrogen. Beaulieu et al.

UN Review of Recent Climate Research Concludes That Impacts Of Climate Change Coming Faster Than Anticipated

This is despite the fact that natural variation will partially offset the warming signal from greenhouse gas emissions. The observed increase in greenhouse gas concentrations are raising concern among some scientists that warming of between 1.4 Marine ecosystems as a whole may see a species turnover of up to 60%.
