At 9:30 am on March 12, 1963, in Room 1-B of Manhattan’s Rockefeller Institute, six experts gathered to discuss the implications of a newly identified atmospheric phenomenon: the rising level of carbon dioxide (CO2) caused by the burning of fossil fuels.
The use of biomass, a non-polluting and renewal material, has been a focal point within the chemical industry for quite some time. It’s hardly a mystery that reliance on fossil fuels to produce the earth’s heat, electricity, and other energy sources is both polluting and powering the world at the same time.
Black carbon (BC) aerosols significantly contribute to radiative budgets globally, however their actual contributions remain poorly constrained in many under-sampled ocean regions. The tropical waters north of Australia are a part of the Indo-Pacific warm pool, regarded as a heat engine of global climate, and are in proximity to large terrestrial sources of BC aerosols such as fossil fuel emissions, and biomass burning emissions from northern Australia. Despite this, measurements of marine aerosols, especially BC remain elusive, leading to large uncertainties and discrepancies in current chemistry-climate models for this region. Here, we report the first comprehensive measurements of aerosol properties collected over the tropical warm pool in Australian waters during a voyage in late 2019. The non-marine related aerosol emissions observed in the Arafura Sea region were more intense than in the Timor Sea marine region, as the Arafura Sea was subject to greater continental outflows. The
ANKARA - Despite declines in deaths from household air and water pollution, pollution still kills more than 9 million each year, or one in six deaths worldwide, according to research published Wednesday in a top medical journal. "Over the past two decades, deaths caused by the modern forms of pollution have increased by 66 percent, driven by industrialization, uncontrolled urbanization, population growth, fossil fuel combustion, and an absence of adequate national or international chemical policy," the study in Lancet Planetary Health said. More than 90 percent of pollution-related deaths happen in low- and middle-income countries. Air pollution causes over 6.5 million deaths each year globally, while lead and other chemicals are responsible for 1.8 million deaths. Increases in pollution-related deaths are especially evident in south Asia, east Asia, and southeast Asia. In Africa, household air pollution and water pollution are still the main causes of pollution-related disea
