Most home air quality monitors are limited in their abilities—as well as their reliability—so if you’re concerned about the air quality inside your home, the first thing we suggest you do is monitor the air outside, because outdoor conditions often determine indoor conditions. There’s no simpler way to do that than to use the Environmental Protection Agency’s AirNow mobile app, available free on iOS and Android. Searchable by zip code or place name, and presented on a map, AirNow’s air quality readings come from direct measurements ...
"Ventilation is the way forward," says infectious disease doctor Abraar Karan of Stanford. Here's how to get better air flow at home, in schools and offices — even in gyms — to stave off COVID.
Humanity is on thin ice. Only rapid reductions in fossil fuel use, increased efficiency and deep reductions in greenhouse gas emissions in all sectors can mean we avoid the worst of climate change, according to a new report published by the United Nation's (UN) Intergovernmental Panel on Climate Change (IPCC). The new report should serve as a "a survival guide for humanity" ...
Direct air capture (DAC) technologies extract CO2 directly from the atmosphere at any location, unlike carbon capture which is generally carried out at the point of emissions, such as a steel plant...
Find out how much carbon dioxide levels have changed during your lifetime! Seeing what CO2 levels were like the year you were born compared to today.
Mauna Loa is an active volcano on 'Big Island', the largest of the chain that makes up the state of Hawaii. It does not erupt that often; the last four times at the time of writing (2023) were in 1950, 1975, 1984 and 2022-23. The summit is 4,169 metres (13,679 feet) above sea level. The observatory that takes regular CO2 measurements is situated some 6.4 kilometres (4 miles) from the summit, on the volcano's northern slopes. Here, the prevailing winds are the north-easterly Trades, blowing in clean air off the Pacific Ocean. Hour to hour CO 2 l ...
Experiments involving various gas mixtures had demonstrated the heat-trapping properties of water vapour, CO 2 and methane in the 1850s. But those effects were yet to be quantified - there were no meaningful numbers. It was to be another 40 years before that happened. Swedish scientist Svante Arrhenius (1859-1927) was the person who ...
GFW at 11:02 AM on 16 October, 2009 · My apologies for what is in effect a repost, but I asked this question at the bottom of a second page of comments where I first saw this diagram. Here I can be first :-) (and I think it's a relatively important question) There is one thing that bothers me about figure 1 (the differential spectrum). The decreased emission in certain absorption bands makes perfect sense. But it's a fact of the (surface) instrumental record that the planet was (a little) warm...
