Comments Off on Humans can’t count on rainforests to offset their carbon

Instead of absorbing carbon dioxide from the air, tropical rainforests could become a source of carbon in the atmosphere as soon as the next decade. Long appreciated as “carbon sinks,” those days will soon be over, according to a new study published in the journal Nature. “We’ve found that one of the most worrying impacts of climate change has already begun,” Simon Lewis, study author and plant ecologist at University of Leeds, told The Guardian . “This is decades ahead of even the most pessimistic climate models.” Researchers spent 30 years tracking 300,000 trees in African and Amazonian rainforests. Their work took them to remote sites, and even required a week in a dugout canoe traveling deep into the Democratic Republic of the Congo. The team tagged individual trees with aluminum nails, charting their height and diameter every few years and calculating the carbon stored in both the surviving trees and those that died. The Amazonian forests — which face higher temperatures and worse droughts — were weakening first, but the African forests weren’t far behind. The researchers based their projections that the forests will soon turn into carbon sources on a statistical model, their own observations and trends in emissions, rainfall and temperatures to predict how forests will store carbon in the near future. Carbon uptake by tropical forests peaked in the 1990s. Back then, the forests absorbed about 17% of the carbon dioxide humans generated. But droughts, deforestation and high temperatures have adversely effected these carbon sinks. By last decade, forests could only take about 6% of global emissions off our hands. “Humans have been lucky so far, as tropical forests are mopping up lots of our pollution , but they can’t keep doing that indefinitely,” Lewis said. “We need to curb fossil fuel emissions before the global carbon cycle starts working against us. The time for action is now.” + Nature Via The Guardian and Phys.org Image via Etienne Delorieux

Comments Off on Upcoming vegan festivals around the US in 2020

As plant-based eating has crept into the mainstream in recent years, vegan festivals have proliferated. In addition to the long-established fests, like those in Boston and Portland , Oregon, vegan fests have sprung up in surprising places, from West Virginia to Houston. This is by no means an exhaustive list of vegan events but a sampling of some of the top 2020 U.S. vegan festivals, large and small. Vegan Street Fair Los Angeles, March 21-22 The Vegan Street Fair in the North Hollywood neighborhood of Los Angeles takes over a boulevard and fills it with vegan food and product vendors. Sample everything from plant-based “mozzarella” sticks, burgers, fried “chicken”, macaroni and “cheese” bites and more. The event is free, and you can purchase small samples or full meals from vendors. If you live in the area, the street fair is a larger extension of the weekly Vegan Exchange event in the same neighborhood.

On March 22, locals will celebrate all things vegan in beautiful Forsyth Park at the Savannah Veg Fest . Organizers are asking folks to RSVP for an accurate head count, as they’re aiming for a zero-waste event. Whole food advocate Dr. Michael Greger, author of How Not to Die, is the keynote speaker. Inland Empire Vegan Festival, March 28 The Inland Empire is a vast swath of southern California between Los Angeles and Nevada. While California is known as a land full of vegans, the Inland Empire is less so. Edward Yniguez and Kawani Brown, in partnership with their nonprofit Plant Based For All, are behind several popular vegan events in southern California, including the annual Long Beach Vegan Fest. Last year, they put on the first Inland Empire Vegan Festival . “We didn’t know what to expect,” Yniguez told Inhabitat. “It was just a huge response. That’s why we’re doing it again.” Expect dynamic live performances from musicians like Mia Sera and Rebecca Jane, and a music fest-feel that might make you want to stay all day. Yniguez recommended the perfectly spiced vegan carne asada from Cena Vegan, which will be at the fest. “The seasoning, how they do it, that’s the killer right there.” VIP tickets get you early access to the event, a swag bag and a shady, seated area by the stage. Puerto Rico Vegan Fest, March 29 Started in 2016, the largest vegan festival in Puerto Rico features 25 food kiosks from around the island, cooking demos, an art exhibition, vendors selling cruelty-free crafts and special activities for kids. An exercise pavilion features talks about vegan athletes, a boot camp class with Malcolm Cuadra and Cris “Chally” Maldonado and the Booty Vegan Workout led by trainer and herbal nutritionist Pearl Alessandra. Santa Cruz VegFest, April 11 Santa Cruz, California always makes the lists of top vegan cities. So you can expect it to throw an especially good vegan festival. More than 5,000 people attended in 2019. This year, more than 100 exhibitors will be showing off cruelty-free beauty products, educating people on animal-related nonprofits and offering samples of vegan foods at the Santa Cruz VegFest . Experts will lecture on plant-based kids, food justice and vegan nutrition. Internet sensation Brian Manowitz, better known as the Vegan Black Metal Chef, is sure to draw legions of fans. Alabama Vegan Fest in Birmingham, April 26 Desare Flournoy, owner of Elegance on any Budget, founded this festival last year and was thrilled to have more than 2,000 people attend. Flournoy told Inhabitat that this year’s fest will include several local bands, spoken word performers and belly dancers. She’s also introducing a series of speakers, with topics like managing fibromyalgia naturally and understanding veganism. The Alabama Vegan Fest aims to welcome omnivores and the vegan-curious, not just die-hard vegans. Orcas Veg Fest, May 16 If you find yourself in Washington State’s San Juan Islands in mid-May, support the fledgling Orcas Veg Fest , debuting in 2020. In addition to the food samples and educational booths, the Orcas Winery will facilitate a special wine and beer garden. Plant-Based World Conference & Expo 2020, New York, June 5-6 This one is for the pros. Now in its second year, the Plant-Based World Conference & Expo bills itself as “The only professional 100% plant-based focused event for food service, retail, and healthcare professionals, distributors, investors, manufacturers, and the savvy consumer community.” Want to find out what’s next in revolutionary plant-based products? Looking to invest in the next big vegan thing? Looking for new suppliers for your wellness business? Network on the exhibition floor and attend sessions like “Data-Driven Plant-Based Merchandising: How to Turn Retail Insights Into Results” and “Why Big Food is Betting Big on Plants.” Vegan SoulFest in Baltimore, Aug 22 Baltimore’s seventh annual Vegan SoulFest invites the local community to bring their lawn chairs and spend a summer day in Clifton Park soaking up soul and hip-hop music, watching cooking demos, trying yoga or a workout with Khnum “Stic” Ibomu (now a wellness trainer) of the legendary rap group Dead Prez and, of course, eating lots of good vegan food. Co-founders Naijha Wright and Brenda Sanders are deeply involved in the local vegan scene. Wright co-owns vegan soul food restaurant Land of Kush , and Sanders heads a public health organization and co-directs an animal advocacy group. Portland VegFest, October 24-25 Now in its 16th year, Portland hosts one of the country’s biggest vegan festivals. The schedule hasn’t been released yet, but expect tons of food samples and a full day of lectures and cooking demos from this two-day fest. If you’re especially interested in health, a plant-based nutrition conference takes place on the Friday before Portland VegFest . Boston Veg Food Fest, October 24-25 Another biggie, the two-day Boston Veg Food Fest is turning 25 this year! There will be plenty of exhibits and speakers, not yet announced, not to mention an abundance of vegan foods to try. Expect to be greeted by a huge inflatable cow. The event, parking and food samples are all free. Seed Food and Wine Miami, November 5-8 For a more upscale veg experience, Seed bills itself as, “the premiere plant based food and wine festival in the country.” Activities span a week and include celebrity chef dinners, yoga, spirit tastings and endless vegan food and wine samples from more than 150 restaurants and brands.

Comments Off on Report Shows Greenland’s Ice Sheet is Melting from Above AND Below Due to Heat from the Earth’s Mantle

Greenland’s arctic ice sheet is in trouble – and it turns out that global warming isn’t the only force at work. A new study in Nature Geoscience by the GFZ German Research Center for Geosciences shows that high heat flow from the planet’s interior into the lithosphere (the area between the Earth’s crust and upper mantle) is accelerating Greenland’s ice melt.

Comments Off on Study Shows the Antarctic Ozone Hole is Contributing to Global Warming

Climate scientists at Columbia University in New York have discovered that the hole in the Earth’s ozone layer may be contributing to global warming by altering wind patterns and cloud cover in the southern hemisphere. These meteorological changes appear to be affecting the way the sun’s radiation reflects off the clouds, leading to a warmer planet.

Comments Off on Earth’s Temperature 30-50% More Sensitive to CO2 than Previously Thought

Image credit: suburbanbloke /Flickr Studying past climates can help scientists predict how the planet will change in the future. Using historical data, scientists at the University of Bristol, have developed a new model of climate change they believe is more accurate than previous estimates. Leaving certain data out of climate models, researchers discovered, has led to exceedingly modest estimates of the effect of carbon emissions on the planet….
