Number of premature deaths worldwide caused by consumption in G20 nations

Added: 08.11.2021 21:37 | 252 views | 0 comments

The haze that blurs a blue sky or a beautiful skyline is caused by particulate matter, often made from pollution, less than 2.5 microns wide. Despite their microscopic size, PM2.5 are responsible for more than 4 million premature deaths every year. A new study shows that the pollution caused by consumption in the world's biggest economies leads to half of those deaths.

Highways shape the sociology of cities

Added: 08.11.2021 21:37 | 217 views | 0 comments

The development of transport infrastructure is a central issue for states, which spend billions to connect cities. But what is their real effect on the municipalities concerned? Researchers have looked at the evolution of the income composition of the population of cities in Switzerland once they are connected to the motorway network. By analyzing data from 1950 to 2010, they found that this new accessibility leads to substantial benefits for wealthy people, but indirect costs fall disproportionately on people with low incomes.

Climate change will triple impacts to world’s 'life zones' unless emission rates are dramatically reduced

A new study that modeled changes in the world's 45 different 'life zones' from climate change revealed that climate impacts may soon triple over these areas if the earth continues 'business-as-usual' emissions.

Twenty-four trillion pieces of microplastics in the ocean and counting

Added: 08.11.2021 21:37 | 229 views | 0 comments

Based on a total of 8,218 pelagic microplastic samples from the world's oceans collected between 2000 and 2019, a team of scientists has developed a publicly available dataset for assessing the abundance of microplastics and their long-term trend in the world's upper oceans. The team found 24.4 trillion pieces (82,000--578,000 tons) of microplastics in the world's oceans, but the actual amount is likely to be much greater.

The ripple factor: Economic losses from weather extremes can amplify each other across the world

Added: 08.11.2021 21:37 | 213 views | 0 comments

Weather extremes can cause economic ripples along our supply chains. If they occur at roughly the same time the ripples start interacting and can amplify even if they occur at completely different places around the world, a new study shows. The resulting economic losses are greater than the sum of the initial events, the researchers find in computer simulations of the global economic network. Rich economies are affected much more strongly than poor ones, according to the calculations. Currently, weather extremes around the world are increasing due to greenhouse gas emissions from burning fossil fuels. If they happen simultaneously or in quick succession even at different places on the planet, their economic repercussions can become much bigger than previously thought.

Affordable policy which could stop fossil fuels causing global warming

Added: 08.11.2021 21:37 | 252 views | 0 comments

Imagine a single policy, imposed on one industry, which would, if enforced consistently, stop fossil fuels causing global warming within a generation. The Carbon Takeback Obligation could do just that. It requires fossil fuel extractors and importers to dispose safely and permanently of a rising fraction of the CO2 they generate, with that fraction rising to 100% by the year of net-zero. Critically, this would include carbon dioxide generated by the products they sell.

A new analysis finds that if greenhouse gas emissions continue along the high-emissions scenario, low-to-no-snow winters will become a regular occurrence in the western U.S. in 35 to 60 years.

Urban areas across the US are undercounting greenhouse gas emissions

Methane emissions from the distribution and use of natural gas across U.S. cities are 2 to 10 times higher than recent estimates from the Environmental Protect Agency, according to a new study. In Boston, methane emissions from the natural gas system are six times higher than recent estimates by the Massachusetts DEP and have not significantly changed in eight years, despite legislation aimed at repairing leaks in natural gas pipelines.

Historical analysis finds no precedent for the rate of coal and gas power decline needed to limit climate change to 1.5°C

Added: 08.11.2021 21:37 | 202 views | 0 comments

Limiting climate change to the 1.5°C target set by the Paris Climate Agreement will likely require coal and gas power use to decline at rates that are unprecedented for any large country, finds an analysis of decadal episodes of fossil fuel decline in 105 countries between 1960 and 2018. Furthermore, the findings suggest that the most rapid historical cases of fossil fuel decline occurred when oil was replaced by coal, gas, or nuclear power in response to energy security threats of the 1970s and the 1980s.
