According to recent projections, the number of people living on Earth could exceed ten billion by the end of this century. Now, a new study has examined what it would take to reverse that unrelenting growth and achieve a sustainable population that is less threatening to biodiversity and ecosystems around the world. Short of a global catastrophe, scientists say, the only way to halt this population momentum is to institute a planet-wide one-child policy within a few decades.

New study links carbon emissions and climate warming
Research has identified, for the first time, how global warming is related to the amount of carbon emitted.
​A team of researchers from the universities of Southampton, Bristol and Liverpool have derived the first theoretical equation to demonstrate that global warming is a direct result of the build-up of carbon emissions since the late 1800s when human-made carbon emissions began. The results are in accord with previous data from climate models.
The theoretical equation reveals the complex relationship between carbon dioxide levels and the ocean system. Burning fossil fuels increases atmospheric carbon dioxide levels leading to global warming and the greenhouse effect, which is partly offset by the oceans taking in both heat and carbon.
Do City Birds Outlive Country Birds?
Researchers at the Smithsonian Migratory Bird Center have found four bird species living in the Washington, D.C., metropolitan region that survive longer than those living in rural settings. The study was led by the Migratory Bird Center using the Smithsonian’s Neighborhood Nestwatch program in which citizen scientists and researchers visit participating residences and parks to collect information about local bird populations. From 2000 to 2012, Neighborhood Nestwatch participants captured, tagged and released more than 7,000 birds from about 280 sites within the urban forest of Rock Creek Park, suburban Maryland backyards and the National Mall.
What Drives the Global Warming Debate?
Scientists have presented the most comprehensive evidence to date that climate extremes such as droughts and record temperatures are failing to change people’s minds about global warming. Instead, political orientation is the most influential factor in shaping perceptions about climate change, both in the short-term and long-term, said Sandra Marquart-Pyatt, a Michigan State University sociologist and lead investigator on the study.
Education is a key to climate change adaption
Given that some climate change is already unavoidable investing in empowerment through universal education should be an essential element in climate change adaptation efforts, which so far focus mostly in engineering projects, according to a new study from the International Institute for Applied Systems Analysis (IIASA).
The article draws upon extensive analysis of natural disaster data for 167 countries over the past four decades as well as a number of studies carried out in individual countries and regions, published last year in a special issue of the journal Ecology and Society.
Is Premium Milk on the Horizon?
Could premium milk be the greatest coup for beverage companies since bottled water? Coca-Cola apparently thinks so. Like its competitors within the beverage industry, the company is trying to find new ways to boost profits since their flagship products, fizzy drinks, have long been suffering from flat sales. While more consumers avoid both sugary and diet sodas and hipsters find alternatives from cold brewed bottled coffee to kombucha, Coca-Cola’s shareholders want increased sales. Premium milk could be the answer for Coke. Coca-Cola is a major investor in Fairlife, which promises to transform the dairy industry by providing “more vroom for your milk.” Starting with the marketing, this is not your parents’ or grandparents’ dairy: instead of pastoral scenes of farmers and cows, the ads are a composite of Alicia Silverstone Aerosmith videos, Marilyn Monroe’s iconic Seven Year Itch photo and a certain scene in Something about Mary. So what is all the fuss about? After all, it is just milk, right? Not according to Coca-Cola.
