Ask a Scientist: ‘Danger Season’ Summers Disproportionately Harm Disadvantaged Communities

Union of Concerned Scientists

JDB: Cities have dense concentrations of asphalt, cement and other surfaces that absorb solar heat during the day and radiate it back into the environment. Obviously, the federal government also has a role to play to mitigate carbon emissions and protect the country from unavoidable climate impacts.

Back in Black: Creating positive changes by focusing on a short-lived pollutant

HumanNature

This is because of black carbon’s enhanced ability to absorb visible light; it actually absorbs nearly a million times more energy per unit mass than CO 2. Black carbon’s lifetime is on the order of days to a couple weeks, which is about 0.004% of the lifetime of other pollutants like CO 2 (which has a lifetime of 300 – 1000 years).

Green jobs for physics graduates: policy and behaviour change

Physics World

Lo first became interested in this area while studying physics and astronomy at Durham University , UK, where her final-year project looked at how to calibrate telescopes to correct for atmospheric effects on the radiation they detect. To pursue this further, Lo did a PhD in atmosphere, oceans and climate at the University of Reading , UK.

Getting physical with the climate crisis

Physics World

An area of high pressure above the Pacific Ocean was driven eastwards through the jet stream by a “Rossby wave” – a planetary-scale fluctuation arising from the Coriolis force. The Rossby wave eventually “broke”, dumping its energy – like an ocean wave hitting the shore – to create an area of high pressure locked over western Canada and US.

Climatology: The Science of Global Weather Systems over the Long Term

Environmental Science

From the ocean oscillations to trade winds, pressure systems that drives temperature, airborne particles that influence local conditions and even the phases of the moon and Earth's wobble all affect the climate (1). The east of the ocean is colder than normal while the west is warmer than average. What Climatology Is.

Environmental Law: Government and Public Policy Towards the Environment

Environmental Science

Acidification : Reducing the pH rating of a substance making it more acidic in nature, for example, increased carbon emissions lead to the oceans absorbing more of it, increasing acidification and damaging ecology such as coral bleaching. Radiation : The transmission of energy through space. For Ecology.

Deserts as Ecosystems and Why They Need Protecting

Environmental Science

Surface albedo is high - heat acquired during the day is radiated at night. Radiation is intense - both in terms of how much deserts receive and how much they reflect back into the environment. Many are not aware that deserts are a net carbon sink, providing some relief from the increase in greenhouse gases.
