warmed when exposed to sunlight & concluded that rising water and CO2 in the atmosphere would increase temperature in 1856. Amongst Tyndall's contributions (following Foote’s paper, but without reading it), he investigated Earth's #atmosphere greenhouse effect by measuring the infrared absorption of atmospheric gases (nitrogen, oxygen, water vapour, carbon dioxide, ozone, methane etc.) in 1859. In case you thought the #science behind #climateChange was newfangled... it's not.

This poetic quotation is a good reminder to stop polluting our own home. What we do to the atmosphere has direct impact on us and the environment.

Water vapour is a greenhouse gas but clouds can reflect sunlight. Warming can increase likelihood of severe storms or drought in different areas. The interplay between warming and the water cycle is complex but these changes can have an array of negative impacts. In Canada this summer we’ve seen horrendous forest fires which are linked

to higher temperatures and lack of rain.

The clouds represented are shown as they would appear in the sky; the lower altitude clouds are lowest, the mid-altitude clouds in the middle and the high altitude clouds at the top. We have cumulonimbus, stratocumulus and cumulus at the bottom. There are three types of altocumulus and one altostratus in the middle. The top level contains cirrocumulus and two types of cirrus clouds. Each is denoted by its own symbol.⁠
