Rafts, rainbow, & dark clouds looming, Colorado River, 2009
Due to decades of historic drought, Lakes Mead & Powell, 2 largest reservoirs in US, are approx 3/4 empty. Fed gov't gave deadline of today for 7 states that depend on Colorado 💧 to reach consensus
2/5 ...on substantial cuts to their water use;
"Federal officials in June called for the seven states to come up with plans to drastically reduce water diversions by 2 million to 4 million acre-feet per year, a reduction of roughly 15% to 25%."
Today is birthday of 2 great writers of powerful reflections on rivers:
Langston Hughes (1901 - 1967)
Jason Isbell (b. 1979)
A thread on their words on rivers, including "The Negro Speaks of Rivers" (1921) and "River" 99 years later

Hughes wrote "A Negro Speaks of Rivers" when he was 17 after he crossed the Mississippi while traveling from his home in Cleveland OH to visit his father who was living in Mexico. Published in 1921 in The Crisis, it marks start of his literary career

New York City just broke record for latest measurable snowfall (previous record was January 29, 1973) and will soon break record for longest stretch without snow (332 days, set in Dec. 2020) - and no snow in 10-day forecast...
The first detailed draft of the new post-2020 global biodiversity framework was released by the Convention on Biological Diversity (CBD) in July, calling for protection of “at least 30% of land and sea areas globally.” 2/19 @david_tickner@MicheleThieme cbd.int/article/draft-…
This overarching goal for protection of “land and seas” continues a pattern in global conservation policies and plans: omission of freshwater habitats such as rivers, lakes & wetlands.
Beyond omission in high level goals, what about tracking of progress? 3/19
Though origins of SARS-CoV-2 remain uncertain, all previous pandemics of past century involve zoonotic diseases. Activities bringing people, domestic & wild animals into close contact, in new ways, increase spillover risk @WWFscience@WWFLeadWater forbes.com/sites/jeffoppe…
2/7
These activities include deforestation, intensified livestock operations on cleared land, + wildlife hunting & trade. In figure, green symbols represent drivers (including ways that we manage the environment) that increase the risk of spillover.
Over the past century, novel infectious diseases have been emerging at an increasing rate, with 3-4 new diseases identified annually. The majority of these (60%) have been zoonotic, with most (72%) coming from wildlife.
#2 To bend the curve on freshwater biodiversity, improve water quality.
The Cuyahoga River (below in @CVNPNPS) once was biologically dead from pollution. Actions-local to federal-tackled pollution & bent the curve for Cuyahoga; sections which lacked fish now have > 40 species.
#3 to bend the curve on freshwater biodiversity loss, protect and restore critical habitats.
Ramsar designation and other protected areas can safeguard habitats and species, such as this American crocodile in the Terraba-Sierpe National Wetlands in Costa Rica
