Not exact matches

And while ozone high in the atmosphere helps shield Earth from the sun's ultraviolet radiation, at ground level, it mixes with fine particulates to form breath - choking smog.

As shown in previous studies, the litter from the polluted site, which had endured high levels of atmospheric nitrogen oxides and ozone, had higher nitrogen content than litter from the clean site.

At high levels, tropospheric ozone can cause respiratory problems from asthma to emphysema.

In the high atmosphere, ozone plays a crucial role in shielding the surface from harmful levels of ultraviolet light.

Higher levels of ultraviolet radiation penetrating the Earth's dwindling ozone layer may be driving some species of frogs to extinction, according to researchers from Oregon.

Ozone doesn't just live high in Earth's atmosphere; near the ground, it contributes to smog, and ground - level ozone has gradually increased in most places because of industrial pollution from vehicles and fossil - fuel burOzone doesn't just live high in Earth's atmosphere; near the ground, it contributes to smog, and ground - level ozone has gradually increased in most places because of industrial pollution from vehicles and fossil - fuel burozone has gradually increased in most places because of industrial pollution from vehicles and fossil - fuel burning.

Early Earth lacked an ozone layer to act as a shield against high - energy solar radiation, but microbes flourished by adapting to or finding other forms of protection from the higher ultraviolet radiation levels.

IPCC [26] projects the following trends, if global warming continue to increase, where only trends assigned very high confidence or high confidence are included: (i) increased malnutrition and consequent disorders, including those related to child growth and development, (ii) increased death, disease and injuries from heat waves, floods, storms, fires and droughts, (iii) increased cardio - respiratory morbidity and mortality associated with ground - level ozone.

Modeling studies caution that warmer days will lead to higher concentrations of ground - level ozone and smog, which cause sickness and death from respiratory and cardiac disease (79).

Tuft's photographs document the effects of high levels of these light spectrums, usually found in places suffering from ozone depletion.

Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).

There is growing evidence from EuroHEAT that the effects of heat - wave days on mortality are greater, particularly among the elderly, when levels of ozone or particulate matter are high.

In 2013, Fort Collins and Denver received «F» grades from the American Lung Association for high levels of ground - level ozone, a key element of smog; Colorado Springs received a «C» grade.

A paragraph from a 2007 United Nations - sponsored report provides a depressing introduction: «In the air, (reactive nitrogen) can contribute to higher levels of ozone in the lower atmosphere, causing respiratory ailments and damaging vegetation.

On ground level ozone they say they have a high confidence that the base line will change over the 21st century from either slightly less to slightly more, but it won't be exactly the same.

During extreme heat events, nighttime temperatures in the region's big cities are generally several degrees higher28 than surrounding regions, leading to increased heat - related death among those less able to recover from the heat of the day.36 Since the hottest days in the Northeast are often associated with high concentrations of ground - level ozone and other pollutants, 37 the combination of heat stress and poor air quality can pose a major health risk to vulnerable groups: young children, the elderly, and those with pre-existing health conditions including asthma.29 Vulnerability is further increased as key infrastructure, including electricity for potentially life - saving air conditioning, is more likely to fail precisely when it is most needed — when demand exceeds available supply.

IPCC [26] projects the following trends, if global warming continue to increase, where only trends assigned very high confidence or high confidence are included: (i) increased malnutrition and consequent disorders, including those related to child growth and development, (ii) increased death, disease and injuries from heat waves, floods, storms, fires and droughts, (iii) increased cardio - respiratory morbidity and mortality associated with ground - level ozone.
