How to estimate energy footprint in highways
Researchers at the Universidad Politécnica de Madrid have developed an application to estimate energy footprint in highways.
This application software, HERA, was developed by researchers of The Transport Research Centre (TRANSyT) at the Universidad Politécnica de Madrid. This application consists of a methodology and a software tool to estimate energy consumption and green house gas of the traffic demand linked to a highway.
Greenhouse gas levels in atmosphere hit new high, UN reports
Surging levels of carbon dioxide sent greenhouse gases in the atmosphere to a new record in 2013, while oceans, which absorb the emissions, have become more acidic than ever, the UN said on Tuesday.
"We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels," said Michel Jarraud, the head of the World Meteorological Organization (WMO) that released a report on the issue on Tuesday.
Ozone layer recovering but remains threatened – UN reports
The Earth’s protective ozone layer is on track to recover by the middle of the century, the United Nations today reported, urging unified action to tackle climate change and curb continued fluctuations to the composition of the atmosphere.
That is according to the assessment of 300 scientists in the summary document of the Scientific Assessment of Ozone Depletion 2014, published by the UN Environment Programme (UNEP) and the UN World Meteorological Organization (WMO).
Researchers suggest reforestation around urban areas to reduce ozone levels
A team of research conservationists with members from several universities in the U.S. is suggesting in a paper they've had published in Proceedings of the National Academy of Sciences, that urban areas could benefit by investing in cost effective reforestation efforts around urban areas that currently suffer from high ozone levels.
Planting trees, they suggest could help cities bring those levels down.
Rising CO2 levels will intensify algal blooms across the globe
Rising CO2 concentrations in the atmosphere will stimulate harmful algal blooms at a global level.
This warning is issued by scientists Jolanda Verspagen and Jef Huisman of the University of Amsterdam, The Netherlands, on the basis of new mathematical models, laboratory experiments and field research. Their results will be published open access in the scientific journal PLOS ONE.
