Here’s a guest column from Greta Thunberg, Adriana Calderón, Farzana Faruk Jhumu and Eric Njuguna that’s running in The New York Times:
The authors are youth climate activists from Sweden, Mexico, Bangladesh and Kenya, working with the international youth-led Fridays For Future movement.
Last week, some of the world’s leading climate change scientists confirmed that humans are making irreversible changes to our planet and extreme weather will only become more severe. This news is a “code red for humanity,” said the United Nations secretary general.
It is — but young people like us have been sounding this alarm for years. You just haven’t listened.
On Aug. 20, 2018, one child staged a lone protest outside the Swedish Parliament, expecting to stay for three weeks. Tomorrow we will mark three years since Greta Thunberg’s strike. Even earlier, brave young people from around the world spoke out about the climate crisis in their communities. And today, millions of children and young people have united in a movement with one voice, demanding that decision makers do the work necessary to save our planet from the unprecedented heat waves, massive floods and vast wildfires we are increasingly witnessing. Our protest will not end until the inaction does.
For children and young people, climate change is the single greatest threat to our futures. We are the ones who will have to clean up the mess you adults have made, and we are the ones who are more likely to suffer now. Children are more vulnerable than adults to the dangerous weather events, diseases and other harms caused by climate change, which is why a new analysis released Friday by UNICEF is so important.
The Children’s Climate Risk Index provides the first comprehensive view of where and how this crisis affects children. It ranks countries based on children’s exposure to climate and environmental shocks, as well as their underlying vulnerability to those shocks.
It finds that virtually every child on the planet is exposed to at least one climate or environmental hazard right now. A staggering 850 million, about a third of all the world’s children, are exposed to four or more climate or environmental hazards, including heat waves, cyclones, air pollution, flooding or water scarcity. A billion children, nearly half the children in the world, live in “extremely high risk” countries, the UNICEF researchers report.
This is the world being left to us. But there is still time to change our climate future. Around the world, our movement of young activists continues to grow.
In Bangladesh, Tahsin Uddin, 23, saw the impacts of climate change in his village and other coastal areas and was moved to action. He is passionate about climate education and has created a network of young journalists and educators to spread awareness, all while organizing cleanups of waterways teeming with plastic waste pollution.
In the Philippines, Mitzi Jonelle Tan, 23, has had to complete her homework by candlelight as typhoons raged outside and wiped out her community’s electricity. She told us there were times she was afraid of drowning in her own bedroom as water flooded in. Now she is leading youth in her country to respond to the aftermath of those typhoons and other hazards through sharing food, water, clothes and support with the most affected communities.
In Zimbabwe, Nkosi Nyathi, 18, is worried about a potential food crisis if weather patterns continue. Heat waves made school a challenging experience for him and his peers. Now he speaks to leaders from around the world to demand the inclusion of young people in decisions that affect their future.
The fundamental goal of the adults in any society is to protect their young and do everything they can to leave a better world than the one they inherited. The current generation of adults, and those that came before, are failing at a global scale.
The Children’s Climate Risk Index reveals a disturbing global inequity when it comes to the worst effects of climate change. Thirty-three countries, including the Central African Republic, Chad, Nigeria and Guinea, are considered extremely high-risk for children, but those countries collectively emit just 9 percent of global carbon dioxide emissions. The 10 countries with the highest emissions, including China, the United States, Russia and Japan, collectively account for nearly 70 percent of global emissions. And children in those higher-emitting states face lower risks: Only one of these countries, India, is ranked as extremely high-risk in the UNICEF report.
Many higher-risk countries are poorer nations from the global south, and it’s there that people will be most impacted, despite contributing the least to the problem. We will not allow industrialized countries to duck responsibility for the suffering of children in other parts of the world. Governments, industry and the rest of the international community must work together to reduce greenhouse gas emissions, as 195 nations committed to do in the Paris Climate Agreement of 2015.
We have less than 100 days until the U.N. Climate Change Conference, also known as COP26, in Glasgow. The world’s climate scientists have made it clear that the time is now — we must act urgently to avoid the worst possible consequences. The world’s young people stand with the scientists and will continue to sound the alarm.
We are in a crisis of crises. A pollution crisis. A climate crisis. A children’s rights crisis. We will not allow the world to look away.
From Colorado Politics (Marianne Goodland) via The Colorado Springs Gazette:
On Monday the bureau announced the first-ever shortage on the Colorado River basin, meaning limitations on water supplies for three states (Arizona, Nevada and California) and Mexico, beginning in January 2022 and continuing for the entire year.
The levels at Lake Mead have been flirting with that 1,075-foot level going back to 2014.
According to the Bureau of Reclamation, both Lake Mead and Lake Powell, the two largest reservoirs on the Colorado River, have been over-appropriated for years. Up until now, the imbalance has been managed and demands met as a result of “the considerable amount of reservoir storage capacity in the Colorado River system.” That includes the dozens of reservoirs in Colorado that feed into the Colorado River.
Water from the Colorado, which begins in Rocky Mountain National Park, is divided up among seven states and Mexico and governed by a 1922 compact that divides the states into upper basin and lower basin regions. The upper basin states are Colorado, Utah, New Mexico and Wyoming, and water is “banked” for those states in Lake Powell.
The lower basin states — Arizona, Nevada and California — rely on the river‘s waters when it reaches Lake Mead, and the hydropower generated by Hoover Dam…
The lower basin states will feel the first impacts of the bureau’s Monday announcement. Arizona is expected to lose 18% of its share from the Colorado, or 512,000 acre-feet of water. According to the Associated Press, that’s about 8% of the state’s total water use…
Nevada will lose about 7% of its allocation, or 21,000 acre-feet of water. But it will not feel the shortage because of conservation efforts and alternative sources of water, the AP reported Monday.
California holds more senior water rights than either of the two states, so its allocation will be spared, at least for now. Mexico will lose 80,000 acre-feet, about 5% of its allocation from the Colorado.
In a statement Monday, bureau officials said the Upper Basin experienced an exceptionally dry spring in 2021, with April to July runoff into Lake Powell totaling just 26% of average, and that’s even despite near-average snowfall last winter. Total Colorado River system storage today is 40% of capacity, down from 49% at this time last year, the bureau stated…
…22 years of drought along the Colorado have meant other reservoirs — not just Lake Mead and Lake Powell — are also being tapped. Last month, the bureau announced it would draw down water from two reservoirs in Colorado and one in Utah, in order to keep Lake Powell, which includes the Glen Canyon Dam, and its hydropower headed to Nevada, going.
The bureau intends to siphon 36,000 acre-feet from Blue Mesa Reservoir in Gunnison County beginning in August. It will draw 20,000 acre-feet from Navajo Reservoir, on the Colorado-New Mexico border in southwestern Colorado. Flaming Gorge Reservoir, in Utah, will send 125,000 acre-feet later this year.
All that water will raise Lake Powell’s levels by 3 feet.
According to the Bureau of Reclamation, on Monday, Lake Mead’s elevation was 1,067.8 feet (35% of capacity). Lake Mead dropped below 1,071.6 feet on June 8, the lowest elevation on record since the lake first filled in the late 1930s…
But the entire Colorado River basin system is struggling, according to a May Bureau of Reclamation draft report on reservoir operations.
At the beginning of water year 2021 (Oct. 1, 2020), the Colorado River’s total system storage was 48% of capacity, the bureau draft report said. As of Sept. 30, total system storage is expected to be at 41% of capacity.
Taylor Hawes, Colorado River program director for The Nature Conservancy, said in a statement Monday the Tier 1 shortage declaration did not come as a surprise.
“The Colorado River has witnessed a steady decline in flows since 2000 that impacts communities, agriculture, industry and the health of our rivers in the region. Even as flows decreased, our demand reductions have not kept pace,” Hawes said.
“The Colorado River can be a model for resiliency and sustainability, but not without a concerted and significant effort by stakeholders in the region.”
Becky Mitchell is director of the Colorado Water Conservation Board and Colorado’s commission for the Upper Basin states. She told Colorado Politics in a statement that “Colorado and the other Upper Basin states understand the risks and vulnerabilities we face in the Colorado River system due to severe drought and a potentially hotter and drier future.”
Also on Monday, governors of 10 Western states, including Colorado, sent a request to the Biden administration to issue a drought disaster declaration for the 10 states, which would allow the states to tap into resources from the Federal Emergency Management Agency.
From The Craig Daily Press:
With lower, warmer water levels in the Yampa River during this extreme drought year, town of Hayden employees are carefully watching operations at the water plant this summer to continue to alleviate taste or odor issues for the town’s 1,100 water taps.
“We are always concerned, but we are paying close attention this year due to the abnormal conditions we’ve been experiencing,” said Bryan Richards, Hayden public works director. “We are trying to be very cognizant of the potential water quality problems that may occur in the river. This is a tremendous drought year, and we want to make sure we don’t miss anything.”
Richards said the usual time of heightened summer concern for low water levels and thus increased algae is lasting longer this year, starting about one month earlier than usual in early July rather than the normal early August. Water levels have dropped at the intake on the Yampa River at the water plant north of town, and water temperatures at the intake have increased by 3 to 5 degrees above normal, rising as high as 75 degrees. Lower, slower, warmer water leads to more algae production…
Fortunately, major improvements to the Hayden water treatment plant during the past three years are working to help mitigate the algae increases, said Town Manager Mathew Mendisco. He said the town spent a total of $2.3 million in water system and plant upgrades with half of the funding coming from the Colorado Department of Local Affairs and other funding from a citizen-approved bond measure. The plant was first built in 1978…
Town of Hayden water users have been under outdoor water restrictions this summer that mimic city of Steamboat Springs restrictions and resulted in a 3% decrease in overall water use compared to the past three years, even though the watering season started earlier this dry year, Richards said. Hayden water users will need to continue water conservation efforts when the town’s 1 million gallon water tank on hospital hill goes offline for a planned refurbishment starting with the tank drained by the end of August through project completion Oct. 20, Richards said.
Mendisco said the town secured $989,000 in low-interest financing to upgrade the tank through a state revolving loan fund managed by the Colorado Water Resources and Power Development Authority. The town qualified for a 1.5% interest rate based on its status as a “disadvantaged community” dealing with the impacts of the transition from coal.
The town has a 500,000-gallon water tank near Yampa Valley Regional Airport, so officials do not anticipate impacts to water customers when the larger water tank is off line…
Mendisco said town officials are working with water engineering firm Leonard Rice Engineers in Glenwood Springs to make a decision on whether the town will take the historic step to call the water reserves it owns in Yamcolo and Stagecoach reservoirs in South Routt County. The town has 500 acre-feet of combined water reserves in the two reservoirs that are managed through Upper Yampa Water Conservancy District.
Mendisco said the decision will be made by Monday depending on rain received before then.
From Colorado State University (Aditi S. Bhaskar):
The following discusses work presented in a journal article by Fillo, Bhaskar, and Jefferson (2021), published in Water Resources Research.
Excess lawn irrigation may contribute to flow in urban streams when more water is applied than plants can use or when sidewalks or driveways receive water from mis-aimed sprinklers. We have applied a new approach to estimating how much flow in streams originally came from excess lawn irrigation by using a tracer that is different between tap water in the Denver, Colorado USA area and local rain. We applied this approach to 13 urban streams and 2 grassland streams in 2019 in the Denver area. We found that, on the dry weather days analyzed, over 65% of flow in urban streams was from tap water, and lawn irrigation was a larger source of water in the streams than leaking water pipes. We also found that grassland streams in the region have less streamflow than urban streams, and are generally dry for part or most of the year whereas urban streams generally flow all year. Lawn irrigation and leaking water pipes contributing to changes in streamflow from part of the year to all year round would be expected to lead to dramatic changes in water quality, bank stability, stream ecosystems, and water yield to downstream rivers. This work gives a new way to analyze how much flow is coming from different sources in urban areas that could be applied to other semi-arid regions. Further work in Denver is looking at applying the same tracer for a longer period looking at how contributions to baseflow change seasonally and from wet years to dry years.
