Monarch butterflies migrate annually from Mexico and California to the northern US and Canada. Multiple facets of climate change are contributing to the variation in migratory patterns and population size. Global warming adversely affects monarchs’ reproductive cycles and development at all stages of life, and delays the butterflies’ natural instincts to make moves. Coupled with increased storms, rain, and high winds, the migration is greatly disrupted.
This great journey is further impeded by the declining availability of the monarch’s main food source and breeding place: milkweed. Increasing temperatures and periods of drought are making it harder for this plant to grow. Illegal logging and land-use changes are limiting the space where it can flourish. Farmers' use of herbicide-resistant varieties of crops allows for more liberal spraying of herbicides and pesticides. This helps control weeds in their fields but also depletes the natural habitat for butterflies.
Monarchs pollinate plants, like milkweed, and allow them to flourish. Without these pollinators the natural food web and human food systems are damaged. This unique migratory process is not only a spectacular sight, but has far-reaching effects on larger ecosystems. #everydayclimatechange#monarchbutterfly#mexico#biosphere#Michoacan#mariposa#ReservadelaBiosferadelaMariposaMonarca#SantuarioElRosario

The world is listening to @gretathunberg. Organizers estimate that on March 15, a remarkable 1.6 million people in 133 countries participated in a climate strike inspired by the 16-year-old Swedish activist’s solo action—mostly students who walked out of #school for a few minutes, an hour or a full day of #protest . Since then, the walkouts have continued, with students around the world united by the #FridaysForFuture and #YouthStrike4Climate hashtags. Thunberg attributes her determination to her diagnosis of Asperger’s, a mild form of autism spectrum disorder. “It makes me see the world differently. I see through lies more easily,” she says. “I don’t like compromising. For me, it’s either you are #sustainable or not—you can’t be a little bit sustainable.” Her openness about her diagnosis, and willingness to share about her experiences of depression, anxiety and eating disorders, are another reason why many see Thunberg as a role model. “To be different is not a weakness. It’s a strength in many ways, because you stand out from the crowd.” Thunberg is in the 2019 class of Next Generation Leaders, featuring rising stars in politics, technology, culture, science, sports and entertainment.

Photo by Ami Vitale @amivitale | On Monday, @UnitedNations released the Global Assessment Report on Biodiversity and Ecosystems. It states clearly that our human activity is taking down one million plants and animals, causing the sixth extinction event on this planet. It’s happening at an incredibly fast and accelerating rate. A million beautiful, ancient creatures like Sudan might breathe their last breath in our lifetime (here, in his final moments, Sudan was comforted by dedicated @olpejeta keeper Zacharia Mutai). Witnessing the last of anything die is something I never want to do again. Witnessing it a million times over may be more than my heart can stand and may be more than our fragile ecosystem can bear. Nature needs us now.
Support and engage @conservationorg@nature_org@nature_africa and other orgs working to build a future in which we can live in harmony with nature. In order to protect prevent more heartbreaking deaths like this, we need to conserve 30% of the planet by 2030. @safariparkdvurkralove#rhinos#DontLetThemDisappear#stoppoaching#kenya

Bleaching is bad for coral. It happens when heat-stressed polyps, the sessile animals that construct coral reefs, eject the photosynthetic algae which usually reside within them. These algae are symbionts, providing nutrients to their hosts in return for shelter, so losing them is harmful to polyps and often results in their death. The higher temperatures brought about by global warming have therefore led to worries that more frequent episodes of bleaching might result in the loss of entire reefs.

For more than a decade, the threat of North America’s largest copper and gold mine has loomed over the headwaters of Bristol Bay, Alaska. This project would directly impact the world’s largest and greatest sockeye salmon run, putting in jeopardy thousands of American jobs, a 10,000 year cultural tradition of subsistence, and a huge sport fishing and tourism economy. Today we have another chance to ensure the Pebble Mine doesn't put this all at risk.

#Regram#RG@cnn: For the first time since 1882, when the first coal-fired power plant started running in the UK, the country has gone coal-free for a full week, according to the National Grid Electricity System Operator. "While this is the first time this has happened, I predict it will become the new normal," said Fintan Slye, director of the ESO. "We believe that by 2025 we will be able to fully operate Great Britain's electricity system with zero carbon."
