The largest source of carbon dioxide emissions globally is the combustion of fossil fuels such as coal, oil and gas in power plants, automobiles and industrial facilities. Carbon dioxide is the major driver of global warming. Although carbon dioxide is produced naturally by volcanoes, the decay of dead plant matter and natural forest fires, almost … Read more
The most common and most important greenhouse gases are carbon dioxide, methane and nitrous oxide. Black carbon is also a potent warmer, although not a greenhouse gas. Carbon dioxide (CO2) This greenhouse gas is present in relatively low concentrations in the atmosphere; prior to the Industrial Revolution, it made up about 0.03 percent of the … Read more
The Earth is habitable because it has a protective blanket of greenhouse gases surrounding it. This blanket traps heat from the sun and allows the Earth to stay at an optimal temperature for life to exist. If this blanket becomes too thick or thin, the Earth’s temperature will respond by becoming too hot or cold … Read more
Solutions: Reduced Speed Overall, speed reductions are a quick, easy and effective way to achieve emissions reductions from ocean-going vessels. Given the recent increases in oil prices, speed reduction makes sense not only environmentally but also economically. Emissions, especially those of carbon dioxide, are directly proportional to fuel consumption. Greater speeds require increased fuel consumption. … Read more
The following effects of climate change will have critical implications for sea turtles: Severe Storms More severe storms, such as hurricanes and tropical cyclones, could increase beach erosion rates, endangering sea turtle nesting habitat. Often severe storms could increase the chance that sea turtle nests will flood, decreasing nesting success rates. Hotter Sands The sex … Read more
During the last few years, Oceana has carried out campaigns to control and report the use of illegal drift nets, both through our observers in ports and through our high-seas campaigns on board the Oceana Ranger and the Marviva Med. During this time, we have located and reported French and Italian netters that continue fishing … Read more
This is one of the most unusual marine areas in the world due to the migratory routes of cetaceans, swordfish, tuna and other species, the heavy oil tanker traffic and the huge amount of concentrated rubbish. The Spanish, Portuguese and Moroccan fishing fleets all operate in this area.
Along with fishing gear and climate change, there are numerous human activity threats to sea turtles. These threats include coastal development, pollution, direct harvest, invasive species and vessel strikes. Coastal Development With the encroachment of hotels, parking lots and housing along nesting beaches, female turtles are forced to use suboptimal nesting habitats. After emerging from their … Read more
During the decade of the 90s, there was a significant increase in the number of vessels in the Moroccan fleet dedicated to fishing with drift nets. Among these, roughly 300 longliners temporarily or permanently used this fishing gear. This transformation was influenced by an increase in the demand for swordfish from the EU and the … Read more
The Azores is a key location for understanding the migration of sea turtles in the Atlantic. All loggerhead turtles found in these waters come from the laying beaches of North America and the Caribbean islands. The biggest longline fishing fleets in this area are the Spanish and Portuguese, searching for swordfish and tuna. Other major … Read more
