Paris, France – The UN’s biodiversity report warning of mass species loss due to human impacts must spark urgent action to protect the world’s forests and oceans and lead to sweeping change in agriculture and food production and consumption.
The global assessment report on biodiversity and ecosystem services from the Intergovernmental Panel on Biodiversity and Ecosystem Services (IPBES) warned that 1 million species are at risk of extinction, more than at any time in human history.
A new study of algal bloom activity in dozens of freshwater lakes around the world provides an answer: For the past 30 years, lakes nearly everywhere have been experiencing more frequent and severe toxic algal blooms—and a changing climate is one reason why.
Researchers at theCarnegie Institution for Scienceused satellite data collected over the past three decades to examine large freshwater lakes across six continents. They searched through more than 72 billion data points to identify statistically significant patterns in algal bloom intensity and found that the severity of algal blooms has increased in over two-thirds of the 71 large lakes studied across 33 countries.
The Sierra Club’s Santa Monica Mountains Task Force (SMMTF) was created in 1972. Our initial efforts were to bring attention and support to the Santa Monica Mountains as a great natural, cultural and recreational resource.
The SMMTF has long played an active role in campaigning to purchase significant open space in these mountains. We have worked to elect political leaders who fight to obtain new parkland and who endorse the highest level of protection for natural resources.
The Canadian government has banned commercial hunting of these vulnerable white pups since 1987 and established strict rules for tourist interaction. That helped to protect the population, but climate change brings new uncertainty to their future. Already the Magdalen archipelago is experiencing stronger storms like Hurricane Dorian, which tore away parts of the islands in 2019. And a diminishing ice barrier no longer protects against winter storms. One study shows that temperatures around the islands have “warmed 4.2 degrees Fahrenheit since the late 19th century, twice the global average.”
The difficulty in reaching harp seals is not for lack of seal numbers. According to Canada’s Department of Fisheries and Oceans (DFO), they are 7.4 million strong in three population groups (Northwest Atlantic, Greenland Sea, and White Sea/Barents Sea). The problem is retreating ice resulting from warming waters. This ice loss affects both the seals, who pup on the ice to avoid predators, and the humans on Quebec’s Magdalen Islands, who rely on the ice for protection from winter storms.
We must ban all gill netting and trawling from Māui habitat out to 100 metres immediately, but why aren’t the same protections being offered for Hector’s dolphins? We know they are dying by the dozen in fishing nets but there is no equivalent proposal to stop those methods in Hector’s habitat.
Male Canyon Wrens songs are composed of clear, descending notes – almost sounding as if the bird is tumbling headfirst into a chasm. Chances are good that a Canyon Wren that’s singing persistently and acting territorial is a male. The female sings much less frequently, usually in response to a male’s song; her song is buzzy and ascending.
Many think this species’ tumbling, echoing notes formone of the West’s most beautiful bird songs. Both males and females sing, although their tunes sound a bit different.
