These high-flying hopes were eventually doused by reality; today, we have the more humble objective of merely keeping the climate stable—in particular, mitigating the impact of greenhouse gases (GHGs). But this is an equally daunting task and one that necessitates political action and widespread...

However, the “man-made"greenhouse effect has now become a big problem.When people produce huge amounts of extr a greenhouse gases 5burning fossil fuels, more heat is trapped in the atmosphere and causes Earth's surface temperature to rise 6(rapid ).There is strong and comprehensive evidence7...

The low-cost and abundant supply of shale gas in the United States has increased the interest in using natural gas for transportation. We compare the life cycle greenhouse gas (GHG) emissions from different natural gas pathways for medium and heavy-duty vehicles (MHDVs). For Class 8 tractor-...
This will put a long-term strain on the ability of developing economies to feed their own people. Climate change is aggravated by the emissions of greenhouse gases from chemical and natural fertilisers used in agriculture which increased by more than a quarter between 2000 and 2010. Other ...
Forest fires can affect climate and weather to a great extent, besides causing severe damage to valuable trees. Wildfires can increase the level of greenhouse gases(water vapor, carbon dioxide, etc), and therefore increase pollution and global warming. However, they are also an important part of...
Low prices and abundant resources open new opportunities for using natural gas, one of which is the production of transportation fuels. In this study, we use a Monte Carlo analysis combined with a life cycle analysis framework to assess the greenhouse gas (GHG) implications of a transition to ...
June 4, 2021Holding the rise of global temperatures to 1.5 degrees Celsius above preindustrial averages, an ambition specified in the Paris Agreement, will require cutting net emissions of greenhouse gases roughly in half by 2030 and to zero by 2050. This enviro...
Global surface warming (global warming hereafter) since the beginning of the twentieth century is unequivocal, and humans are the main cause through the emission of vast amounts of greenhouse gases (GHGs), especially carbon dioxide (CO2)1,2,3. The oceans have stored more than 90% of the hea...
