Worldwide increases in the incidences of asthma, allergies, infectious and cardiovascular diseases will result from a variety of impacts of global climate change, including rising temperatures, worsening ozone levels in urban areas, the spread of desertification, and expansions of the ranges of communicable diseases as the planet heats up, the professional organization representing respiratory and airway physicians stated in a new position paper.
Chagas disease, a parasite-borne illness carried by kissing bugs afflicts millions of people in Central and South America today.
As Asian countries develop, they are emitting more ozone precursors that pollute surface level air. Many studies have documented this pollution being carried by air currents to the western United States.
The U.S. Environmental Protection Agency (EPA) is proposing not to change the greenhouse gas (GHG) permitting thresholds for the Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs.
In 2009, when the United States fell into economic recession, greenhouse gas emissions also fell, by 6.59 percent relative to 2008.
A new study led by the Georgia Institute of Technology provides further evidence of a relationship between melting ice in the Arctic regions and widespread cold outbreaks in the Northern Hemisphere. The study’s findings could be used to improve seasonal forecasting of snow and temperature anomalies across northern continents.
National results indicate that tree cover in urban areas of the United States is declining at a rate of about four million trees per year, according to a U.S. Forest Service study published recently in Urban Forestry & Urban Greening.
It’s not a take on climate change we often hear about. However, one man believes the two are connected.
Indigenous people around the world are among the most vulnerable to climate change and are increasingly susceptible to the pathogen loads found in potable water after heavy rainfall or rapid snow melt.
Extreme summer temperatures are already occurring more frequently in the United States, and will become normal by mid-century if the world continues on a business as usual schedule of emitting greenhouse gases.
Does it matter whether long periods of hot weather happen in June or July, August or September? Scientists studying the subtle effects of heat waves and droughts say that when such events happen makes a big difference.
Anthropogenic climate warming is leading to consideration of options for geoengineering to offset rising carbon dioxide levels. One potential technique involves injecting artificial sea spray into the atmosphere. The sea salt particles would affect Earth's radiation budget directly, by scattering incoming solar radiation, and indirectly, by acting as cloud condensation nuclei, which could lead to whiter clouds that reflect more radiation.
Scientists are preparing to launch a 10-year project to study water resources, gas exchange and carbon cycling in three man-made landscapes built in a half-acre laboratory at the University of Arizona’s Biosphere 2.
Climate change has impacts on forests, fields, rivers -- and thereby on humans that breathe, eat and drink. To assess these impacts more accurately, a comprehensive comparison of computer-based simulations from all over the world will start this week. For the first time, sectors ranging from ecosystems to agriculture to water supplies and health will be scrutinized in a common framework.
New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published in Nature Geoscience.
The effects of climate change could expose Australians to greater risks from toxic contamination, a leading scientist has warned.
Thirty-thousand-year-old bison bones discovered in permafrost at a Canadian goldmine are helping scientists unravel the mystery about how animals adapt to rapid environmental change.
Might a penguin's next meal be affected by the exhaust from your tailpipe? The answer may be yes, when you add your exhaust fumes to the total amount of carbon dioxide lofted into the atmosphere by humans since the industrial revolution. One-third of that carbon dioxide is absorbed by the world's oceans, making them more acidic and affecting marine life.
Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in in the world's drylands, according to a new landmark study.
No less than one third of a car's fuel consumption is spent in overcoming friction. This friction loss has a direct impact on both fuel consumption and emissions. However, new technology can reduce friction from 10 to 80 percent in various components of a car, according to a joint study by VTT Technical Research Centre of Finland and Argonne National Laboratory in the United States.
