Their favorite meal, herring, abounds, but climate change means both predator and prey must increasingly migrate further north. The clear and calm waters of Reisafjorden, in Norway’s Far North, have in recent years become the winter playground of the Scandinavian country’s killer whale population. At three degrees Celsius (37 Fahrenheit), the cold water is perfect for the herring which, ahead of the spawning season…

Scientists at the US-based advocacy group the Environmental Defense Fund suggest the short-term warming impact of these additional gases in the atmosphere could be equivalent to 1,200 coal power plants. Considering the importance of rice as a staple food crop, providing more calories to the global population than any other food, the researchers have recommended ways to adapt farming practices and make its cultivation…

So far, advocates and politicians have tended to focus on reducing fossil fuel consumption through technology and/or policy, such as a steep carbon tax, as climate solutions. These proposals are, of course, essential to reducing manmade carbon emissions—71 percent of which are generated by just 100 fossil fuel companies. For this reason, fossil-fuel–related emissions reductions rightly figure heavily in the national climate commitments of…

The study examines 10 major climate-related issues facing farmers in Africa, Asia, and Latin America and proposes site-specific CSA remedies. These include rotating rice fields with peanuts in Vietnam, manual blight control for cacao in Nicaragua, and planting drought-tolerant varieties of beans and maize alongside each other in Uganda. Where additional investment is required, initial rates of return on investment range from 17 percent…

The Annual Meetings took place in the wake of a new report published by the Intergovernmental Panel on Climate Change in early October, which warned that governments have just 12 years to reduce global greenhouse (GHG) emissions by 45per cent to avert irreversible global warming and limit global average temperature rise to 1.5°C. Countries’ current Nationally Determined Contributions to the Paris Climate Agreement (NDCs)…

Global heating and ocean acidification have already severely bleached 16 to 33% of all warm-water reefs, but the remainder is vulnerable to even a fraction of a degree more warming, said David Obura, chair of the Coral Specialist Group in the International Union for the Conservation of Nature. “It will be like lots of lights blinking off,” he told the Observer. “It won’t happen…

Since 2010, new plant varieties have been developed in molecular laboratories using new plant breeding techniques (NPBTs), including tilling, protoplast fusion, cisgenesis, oligonucleotide techniques, CRISPR-Cas9 and Talen, with CRISPR-Cas9 being more prominent than the rest. With these methods, there is no transfer of a gene from a foreign species like there is with GMOs. On the contrary, new varieties are created by silencing the…

In Bangladesh, low-lying and vulnerable to yearly flooding, farmers are shifting from raising chickens to raising ducks. Ducks can swim. In the Philippines, where half the mangrove forests have been lost to development, biologists are replanting the trees to recreate nature’s protective coastal shield against deadly typhoons. The gnarled tangle of mangrove roots slows the movement of tidal waters, reducing the…

She pointed out that climate-related disasters account for more than 80 percent of all major internationally reported disasters. Climate variability and extremes are already negatively undermining the production of major crops in tropical regions. “So climate variability and extremes, are not only events that will happen in the future; they are occurring now and are contributing to a rise in global hunger,” she warned. Holleman…

Nutrition in Pacific countries is very sensitive to climate extremes. Worldwide, five of the 15 countries considered the most vulnerable to natural hazards are Pacific small island developing states. Vanuatu is ranked as the world’s most vulnerable. Recurring climate shocks such as drought, delayed monsoons, tropical cyclones and floods – and with insufficient recovery time between disasters – have undermined food security across the…

A new international study headed by researchers at Florida State University and Duke University, reveals the outlook may not be as bleak. It finds that these swamps and marshes have a natural biochemical defense mechanism that helps them resist or retard decay -- even in warming temperatures and more severe droughts. "This is good news, because it indicates that scenarios where all this stored carbon…

After ambition comes action. With Pope Francis' moral leadership and the faith community worldwide, the Catholic Church is uniquely positioned to lead a global movement for climate action. Here are three things the Vatican can do to inspire the world and demonstrate its own leadership on climate action. 1) Push for Greater Ambition to Limit Warming To keep global temperature rise well below 2 degrees…

A little more than a year later, with the speedy publication of the 50 Reefs team’s scientific results in June, the project has wrapped and those involved are considering how to proceed. After scientific meetings in Hawaii and Australia featured heated debates, it turned out Kennedy was both right and wrong about the impossibility of the task. In the end, there is no simple straightforward…

But fish will start losing their ability to detect different smells by the end of the century if atmospheric carbon dioxide levels keep rising, scientists warned in a recent study published in the journal, Nature Climate Change. For fish, the sense of smell is “particularly important when visibility is not great”, said Cosima Porteus, a postdoctoral fellow at the University of Exeter in London and…

A recent study of global vegetable and legume production concluded that if greenhouse gas emissions continue on their current trajectory, yields could fall by 35 percent by 2100 due to water scarcity and increased salinity and ozone. Another new study found that U.S. production of corn (a.k.a. maize), much of which is used to feed livestock and make biofuel, could be cut in half by…

This year is shaping up to be a critical one for ocean action. The 53 member countries of the Commonwealth adopted the Commonwealth Blue Charter on Ocean Action earlier this year, a plan to protect coral reefs, restore mangroves and remove plastic pollution, among other actions. Ocean conservation was a centrepiece of the G7 meeting resulting in the “Charlevoix Blueprint for Healthy Oceans, Seas and…

Poor countries could have to pay up to $168 billion more in interest over the next decade as extreme weather events brought on by climate change affect their credit ratings, a study said on Monday. Nations that rely heavily on agriculture are likely to suffer as global temperatures rise, bringing more storms, floods, and droughts that can destroy crops and curb production, according to research…

Investing in climate mitigation Dr. Charles Donovan, Director of the Centre for Climate Finance and Investment at Imperial College Business School, said: "Our work demonstrates that climate change is not only imposing economic and social costs on developing countries, but it is also amplifying existing risks that are already priced in fixed income markets. These impacts will grow. "The good news is that investments in…

Farming, being highly dependent on rainfall, soil health, and temperature, is most vulnerable to change in climate,” says Raj Paroda, former director-general of the Indian Council of Agricultural Research and a senior adviser of the Asia-Pacific Association of Agricultural Research Institutions (APAARI). More than 2.2 billion people in Asia rely on agriculture to make a living, according to data from the Asian Development Bank. The…
