An increase of just 1-2 degrees Celsius in shallow waters on the West Antarctic Peninsula has radically reduced marine diversity, a new study revealed.
The dead zone is primarily the result of nutrient pollution that stimulates massive blooms of algae. When this algae decomposes, oxygen levels drop below levels needed by many Gulf species to survive or develop normally; scientists refer to low-oxygen conditions as hypoxia.
The study has developed the first ever Global Rainfall Erosivity Database and a Global Erosivity Map. It notes that while rainfall provides moisture critical for plant growth, it is also one of the prime causes of soil degradation, referred to as rainfall erosivity, and which threatens food and water sustainability. For experts, global erosivity model predictions are very important since it will help them assess risks, plan and implement effective soil mitigation and restoration strategies.
Canada’s Arctic glaciers have become a major contributor to sea level change, according to glaciologists at the University of California, Irvine (UCI).
Pollution from the controlled fires that burn across Brazil’s São Paulo state during the sugarcane-harvesting season has a negative impact on infant health nearby.
A new study published in The Cryosphere, an European Geosciences Union journal, has found that Bolivian glaciers shrunk by 43% between 1986 and 2014, and will continue to diminish if temperatures in the region continue to increase.
The level of the oceans could rise several meters in the next few years, according to some scientists, after they discovered that the temperatures of the oceans were similar to those of the last period of the warming.
Significant melting of Arctic sea ice is linked to changing global weather patterns, but climate scientists still have a lot of unanswered questions.
Mexican farmers can make higher profits than most other crops so are thinning out pine forests to plant young avocado trees. The popularity of the avocado in the US and rising prices for the “superfood” are fuelling deforestation in central Mexico.
Three NGOs, the Venezuelan Program for Education and Action in Human Rights-Provea, the Peace Lab, and the Working Group on Indigenous Issues at the Andes University, issued a statement blasting Nicolás Maduro’s government’s push to exploit mineral resources on ancestral lands in the Bolívar, Amazonas, and Delta Amacuro states.
According to the website mongabay.com they have obtained a new, high-resolution satellite image of Petroamazona’s suspected pipeline and drilling platforms in the famed Ishpingo-Tambococha-Tiputini (ITT) block. Obtained from Planet, the image was analyzed by the team at the Monitoring of the Andean Amazon Project (MAAP) just after Ecuador announced it had begun drilling in arguably the most biodiverse place on the planet.
New research shows that landowners in Brazil are clearing more forest than government measures suggest. In the satellite image above, black boxes and yellow dots indicate deforestation taking place in the blind spots of Brazil’s forest monitoring system.
An Ayoreo group in the Chaco whose ancestral land was sold to international ranchers in 2012 is battling for its return – and to hang on to their way of life.
Global warming is making the oceans sicker than ever before, spreading disease among animals and humans and threatening food security across the planet, a major scientific report said recently.
Some 92% of the population live in places where air pollution exceeds WHO limits, which can contribute to lung cancer, heart disease, and strokes.
