I am lucky to have been surrounded by many generous people throughout my life. As I wrote in my memoir Source Code, my parents were my first and biggest influences. My mom introduced me to the idea of giving back. She was a big believer in the idea of “to whom much is given much...
Air pollutants emitted from cars are believed to cause cancer and contribute to such problems as asthma, heart disease, birth defects and eye irritation. Greenhouse Gases Emissions from cars increase the levels of carbon dioxide and other greenhouse gases in the atmosphere. At normal levels, green...
Even Bressler found it hard to grasp what this number really meant, so he found another way to express it. That is: For every 4,434 metric tons of CO2 that we add beyond the 2020 rate of emissions, we will kill one person. Those 4,434 tons are equivalent to the current lifetim...

Considering the 500 km scenario, the travel time by zero-emission flight is 2.45, 3.30, and 4.15 h, while the travel cost is £47, £79, and £111. It was assumed that the CO2 emissions from zero-emission flights would be less than 2 kg/person in all scenarios of 500 km. Usin...
Carbon reduction is everyone's responsibility. What kind of person can be regarded as "low carbon family" and what does "low carbon" represent? For us, the lifestyle depicts each person's "carbon footprint" (how much carbon dioxide is produced, used and consumed), and low-carbon life is...
The money earned from selling these credits is mostly used to fund one or more environment-friendly projects. These projects aim to fight climate change by either preventing GHG emissions or removing the same amount of carbon from the air that was emitted by the polluting organization or person....
The first photon can stimulate or induce atomic emission such that the subsequent emitted photon (from the second atom) vibrates with the same frequency and direction as the incoming photon. Mirrors The other key to a laser is a pair of mirrors, one at each end of the lasing medium. ...
Climate change caused by greenhouse gases, which are mainly emitted via the burning of fossil fuels and biomass in the form of carbon dioxide but also include methane, nitrous oxide and fluorinated gases, harms both human and planetary health. Health effects can be direct and indirect and range...
Furthermore the biomass stock of tropical forests and its distribution remain poorly resolved at the regional scale [15,63,64]. Consensus has also yet to be reached on how much carbon is being emitted by changes in tropical land use (see, for example, [1,44,65–69]. There is thus an...
