Electron Beams might reduce NOx (smog) emissions in coal plants and cut costs

coal plant flue gas

With the EPA setting stricter guidelines for NOx emissions fired by coal plants, the industry is now in a position where it needs new, advanced technologies that clean flue gases. Such a solution might came from the U.S. Naval Research Laboratory (NRL), which recently partnered with a leading coal corporation to implement its electron beam technology. The system works by zapping…

World’s largest polluters, China and US, agree to cut emissions in historic agreement

china-pollution

President Obama and Chinese leader  Xi Jinping agreed to sign a deal that will see the US nearly double its efforts to cut CO2 emissions by 2025 and China cap its CO2 emissions for the very first time. This historic agreement between the two largest polluters in the world, which together amount to 45% of all greenhouse gases released in…

Scientists have long known that climate change has a major negative impact on global agriculture, potentially even threatening global food security. But a new research shows that air pollution is actually much more threatening. Anthropogenic climate change caused 3.5% decrease in potential wheat yield on a country level in India; air pollution caused more than 32% decrease in potential yield. Ozone…

Dr. Michael Honeycutt, the top toxicologist in the state of Texas argued that the Environmental Protection Agency (EPA) shouldn’t tighten smog rules because there would be little to no health benefit. “Ozone is an outdoor air pollutant because systems such as air conditioning remove it from indoor air,” he argues on a blog post on the TCEQ website. “Since most…

A trio of newly published studies showed once again that natural gas is not a clean energy bridge – the studies highlighting the various problems associated with natural gas. Firstly, it was shown that emissions databases underestimate the methane released from fossil-fuel extraction in the U.S. Southwest. “A global gas boom is not a replacement for energy and climate policies,” write…

Sweden recycles 99 percent of its garbage. Here’s how they do it

Waste-Management-Sweden-recycling-program-300x290

Recycling is still a field where we have much work to do; while you hear talks about it everywhere, it’s still not done at a satisfying scale in most parts of the world. But Sweden is not part of that group. Virtually all of Swedish garbage is recycled; as a matter of fact, they are so good at making garbage…

Thousands of runners signed up for the Beijing marathon, hoping to better themselves in the 42 km race. But the 34th Beijing International Marathon which took place on Sunday was not a fit place for a record, as air 
pollution soared to 16 times the maximum recommended level. The air in Beijing is among the most polluted urban areas in the world. The…

NASA confirms there’s a huge cloud of methane over southwest US

A cloud of methane gas about the size of Delaware was detected over the Four Corners area of the American southwest years ago. But people didn’t take it seriously, because (believe it or not) – it was so big that they thought it was an instrument error. “We didn’t focus on it because we weren’t sure if it was a true…

Ocean Abyss hasn’t Warmed – Where’s All The Heat?

e. This image shows heat radiating from the Pacific Ocean as imaged by the NASA’s Clouds and the Earth's Radiant Energy System instrument on the Terra satellite. (Blue regions indicate thick cloud cover.)

The ocean abyss hasn’t warmed significantly since 2005, according to a new NASA study, further deepening the mystery of why global warming has apparently ground to halt in the past couple of years. The researchers stress, however, that the findings do not indicate that there isn’t any man-made climate change; sea levels are still rising, it’s just the fine details that…

For the first time, China surpasses the EU in per capita CO2 emissions

China co2

Despite significant steps towards a more sustainable future, China is still the world’s most polluting country – and it’s not only their sheer population that’s the cause. A new study conducted by two British researchers revealed that China emits more CO2 per capita than Europe. They also estimate that we have already released two thirds of the fossil-fuel emissions allowable under…
