What does it mean to be undocumented in the United States, to live in fear of loved ones being deported, to feel the formalized language of being ‘alien’ knowing it is a tactic to dehumanize us? When asked to share our stories, which ones do we tell?
I’ve learned over time how to decipher which version to share and which aspects to keep. For me, it depends on the community in which I tell it and the sense of ‘belonging’ I perceive from the places I share it.
Understanding climate change has meant digging into history, my ancestral knowledge, why my parents moved from Zacatecas, Mexico, to Minnesota, and embracing what makes a place ‘home.’ I learned that Zacatecas was a hot spot for mining, silver, copper, and gold as exports to Canada and the United States. My family held these jobs, which meant handling the TNT for land blasting and other unimaginable work. My dad was a worker in an open mine just a few miles from our home, a profession that left him with the scars to prove the physical demand. When I was born in 1992, both of my parents were already sick, and I was born with a lot of health complications. Doctors told my parents that if we remained in the community, it would be challenging to keep me healthy. I am not sure that my parents made the connection between heavy industry and our sickness. Still, my parents desperately wanted me to be healthy, so we migrated to the U.S. Now, I see the interconnections with corporations who positioned jobs that poisoned us as viable opportunities to make a living and that my parents had to choose between staying and remaining sick or migrating for the promise of health and a better life. I see the sacrifice that they made for me.
I know how people think and talk about immigrants, and I know the importance of what it means to share my story as part of this collective narrative. I know that it will resonate with so many others. I am holding the fear of wanting to protect my people while learning the importance of being more open so that we can be visible and represented in the climate conversation, too.
Moving to Minneapolis, we rented a room, and my school was near the HERC (Hennepin Energy Recovery Center), the state’s largest trash incinerator. We did not know the HERC was burning 1,000 tons of trash per day, with it emitting mercury, lead, carbon monoxide, and dioxins into the air. We did not know that the surrounding community had asthma rates in children five times the national average. I spent childhood years playing in the neighborhood, but I only learned about the dangers of the HERC a year ago. I now recall when we moved to the suburb of Richfield, that my sickness had gotten better. The HERC was built 34 years ago, and for a long time was positioned as “green energy.” I wonder how might things have been different if this information had been more openly available? I am grateful for the work of community groups, environmental justice activists and organizers who are dedicated to telling these truths. Yet, there is more work to do to make this environmental injustice and its importance known in the Latinx community. In my role, as Associate Executive Director of COPAL (Communities Organizing Latinx Power and Action), I have the power and privilege to do something about it.
This begins with recognizing the known patterns: who are the culprits in Minnesota and our homelands? When I was 9 years old, my mom was diagnosed with cancer. I began to unpack the layered and cumulative impacts of environmental injustice following our family from one community to the next. The commonalities are powerful corporations that share a greed that puts people last, extraction of land and labor, and monies made for profit first. Thinking about my origin story in Mexico, I now understand that there were policies in place to lessen harm to the health and viability of the community that could have made it possible for my family to stay, but they were not followed. Here in Minnesota, the Cumulative Impacts Environmental Justice Bill passed in the 2023 Legislative Session, yet there are still loopholes for industries to pollute without facing penalties. So, we must keep asking questions and showing up to hold those accountable. To implement laws that protect our people and put the community first. The journey of learning about who I am, the connections of environmental justice in my own story, and knowing what we have been through to be here fills me with mixed feelings about how people talk or think about immigrants as less than. In reality, climate change and the corporations responsible have played a significant role in migrant stories, and that connection is often overlooked.
In 2016, the hateful rhetoric coming from the President of the United States left an impact on me. I remember doing homework at the dining table after school, and my mom was in the kitchen. We listened as he talked on the news, saying that illegal immigrants were not people but animals. Something deeply stirred in me as I heard threats to make our existence here less visible. As a DACA (Deferred Action for Childhood Arrivals) recipient, which granted me temporary protection, otherwise known as a “Dreamer.” This status and more were at stake, and it was deeply personal. I started teaching citizenship classes so that my community members in Minnesota could become eligible to vote and change the narrative to reflect more accurately seeing people as human beings worthy of that dignity.
With a group of friends, we started teaching courses in Spanish to address the language barrier for a test only offered in English. The first class had thirty participants, and it became an incredibly successful program. In 2018, I met Francisco Segovia, the Executive Director at COPAL. That began our work together at COPAL to address the immediate needs of the Latinx community through policy change. In my role, I work at the intersection of environmental justice, health, wellness, and communications. My pull into this work directly relates to my lived experiences, but making the climate connection to the migrant story is not always accessible to people. It requires deeper awareness and learning for people to unpack their own stories. A big part of this work is listening to people and asking curious questions: where is home? Where are our families from? What cultural aspects, favorite foods, and celebrations make us who we are? What represents home, and how can Minnesota be part of that?
Working on the cumulative impacts of environmental justice and with community members to pass legislation has shown me the importance of sharing our dreams and stories. Crafting stories to share in community are the powerful testimonies that will be essential in public commenting to impact rulemaking where the details and accountability matter and must reflect our lived realities and experiences. Unfortunately, I am not alone in deciphering which version of the story I can tell based on the audience. But I want to get better at leaning into the fullness of what I want to share, despite the reception level I receive or the willingness of mainstream audiences to hear my words. Mostly, I want to share my story in the presence of my beloved community to help others see themselves in my migrant story.

The case for global energy transition has rarely been clearer. The closure of the Strait of Hormuz earlier this year exposed the cost of unplanned, fossil-dependent systems, while the falling cost of renewables, the rising penetration of electric vehicles, and the growing value of demand flexibility have made the direction of travel obvious. The benefits of a clean, secure, integrated system are no longer in dispute. What remains unclear is how to build it.
Countries around the world have called for faster renewable energy deployment and alternative energy arrangements. A secure, affordable, resilient, decarbonised system requires specific investments in specific places in a specific sequence, optimised across sectors and borders. But very few governments have the analytical foundation to translate those imperatives into investment.
The two instruments that are supposed to determine investment priorities for decarbonisation – Nationally Determined Contributions (NDCs) and country platforms – cannot answer the most basic question facing any country undertaking an energy transition: what should the energy system look like?

China and Australia drove global decline in new capacity additions in 2025, but planned production kept growing
To close this gap, every country needs a bankable, economy-wide optimisation model for its energy system. A model is not a plan, but it can help answer the critical question of what the future energy system should look like. It shows how optimal scenarios vary as assumptions and policies are adjusted, calculates investment requirements and sequencing, and quantifies how system costs are affected by assumptions, policies, and exogenous variables like trade policy and financing terms.
Tool for efficient investment
Optimisation is a simplified way of simulating an energy system, but it can be an extremely powerful tool for moving energy planning from reactive (how do we manage the disparate actions in the energy system?) to intentional (what energy system underpins our national objectives?). A model can show how optimal scenarios vary as assumptions and policies are adjusted, and how investment requirements are quantified and sequenced.
Optimisation models can treat the energy system and the sectors it serves as an integrated whole, optimising across sectors and projects in ways that can be mutually reinforcing. If considered independently, growth in industrial demand, transport electrification, and digital infrastructure can add stress to the energy system. But an optimised plan can arrange these and other changes in an efficient, synergistic way.
Two to tango: How governments can unlock private investment for national climate goals
New load can be added where low-cost power is available; industrial customers can ensure the viability of investments in energy supply; electric vehicle charging policy can smooth load curves and reduce costs for all consumers.
Additionally, optimisation modeling can also change the financeability of investments. Taken alone, each project faces uncertainty about the rest of the system, which raises the cost of capital and causes projects to stall or unwind after contracts are signed. A coherent, optimised plan makes visible the coordination that private capital would otherwise have to bet on: identified offtake, sequenced and committed transmission, contracted power supply, and so on.
What COP31 and COP32 should do
The upcoming COPs in Turkey and Ethiopia can shift the center of gravity of international climate cooperation from fragmented commitments to planning. Three moves are urgently needed.
First, optimised, economy-wide, long-term energy system planning must be the foundation on which any meaningful NDC, country platform, or finance commitment rests. NDCs are typically drafted by environment or single-line ministries, with limited cross-sectoral input from ministries of energy, finance, and planning. They contain targets, derived from sectoral strategies or national commitments, not from an analytically grounded picture of what the energy system should look like and what investments would make it work. Country platforms are generally a portfolio of investments assembled from existing project pipelines, rather than derived from a system-level analysis of what an optimised, decarbonised energy system would require.
Second, recognise regions as a key planning unit. Modern integrated energy systems are inherently regional. Renewable endowments are unevenly distributed; balancing variable supply across borders lowers aggregate cost, reduces redundant backup capacity, and unlocks economies of scale no individual nation can achieve. Many energy investments in Southeast Asia, East Africa, Southern Africa and Central Asia may only be financeable in a regional context. Assessing domestic infrastructure without regional optimisation perpetuates the perception that decarbonisation is more expensive than it is.

Third, finance the planning capacity. A coordinated commitment by multilateral development banks, bilateral donors, and philanthropic partners to help every region and its constituent countries develop and maintain their own modelling capability, with open-source tools and regional analytical hubs, would close the most consequential gap in the current architecture. The cost is small relative to current spending on country platforms, failed project preparation, and misallocated infrastructure investment.
This includes supporting regional institutions such as the ASEAN Centre for Energy, the African Energy Commission, regional power pools, and the Latin American and Caribbean Energy Organization to determine what optimised regional systems require. Country-by-country pledging, repeated at every COP, will not deliver what meaningfully integrated systems can.
The 2026 energy crisis made the cost of unplanned, fossil-dependent systems newly visible. That window of clarity will close. The international community should seize the moment to build the planning foundation that has been missing for thirty years, rather than commissioning another round of NDCs or pledges, striving for outcomes neither was designed to deliver.

The world is currently experiencing what is expected to become the strongest El Niño on record – dubbed a “super El Niño” by many.
El Niño is the warm phase of a recurring climate pattern in the tropical Pacific that releases heat from the ocean into the atmosphere.
This temporarily raises global temperatures and reshapes rainfall and extreme weather around the world – impacting the lives of billions of people.
The current El Niño event began in June and is expected to last into 2027.
El Niño is part of a wider climate pattern called the El Niño-Southern Oscillation (ENSO) cycle.
The ENSO cycle also has a cool phase, known as La Niña, as well as a “neutral” phase. El Niño and La Niña events typically last between nine and 12 months, but can go on longer.
Below, Carbon Brief explains how the ENSO cycle works, its impacts on extreme weather and global temperatures and why this El Niño event is projected to be the most intense since records began.

The second-largest reservoir in the US reached a record-low water height on Saturday – just days after the country’s largest reservoir broke its own record.
Both Lake Mead and Lake Powell are located on the Colorado River.
They provide water for populations across seven US states in the south-western US, with around 40 million people getting some or all of their municipal water from the Colorado River.
The river also provides water for around 5.5m acres (22,258 square kilometres) of farmland across Colorado, Arizona, California and the other states in the river basin.
Experts tell Carbon Brief that climate change, population growth and over-consumption are all contributing to the current record-low levels of the reservoirs.
Record lows
At full capacity, Lakes Mead and Powell can hold a combined 68 cubic kilometres of water – enough to supply all household consumption in the contiguous US for nearly 1.5 years. However, the water level in both reservoirs has been declining for decades.
The chart below shows the water level of Lake Mead, in metres above mean sea level. The reservoir, which began to fill in 1935 following the construction of the Hoover Dam, has a “full pool” maximum capacity of 347.60 metres. The water level in Lake Mead reached a record low of 317.11 metres on 7 August.
The following chart shows the water level of Lake Powell, in metres above mean sea level. Lake Powell’s full-pool level is 1,127.76 metres.
While the reservoir reached its maximum capacity several times in the 1980s, it has not done so since. On 15 August, the water level in Lake Powell was recorded at a new record-low of 1,072.87 metres.
Both reservoirs have continued to decline in the days since breaking their respective records. The downward trend will largely continue in both lakes until next spring, when the snowpack in the mountains of the Upper Colorado River Basin begins to melt, says Dr Jack Schmidt, a senior research scientist at Utah State University’s Center for Colorado River Studies. He tells Carbon Brief:
“The big dilemma of the moment is that we’re only in the middle of August, and we have no assurance of what the coming winter will be. The only thing we can be sure of is that we will be depleting overall total basin reservoir storage from now until, roughly, early April.”
Compounding factors
The record lows across the two reservoirs are the result of several compounding factors, experts tell Carbon Brief.
Since the turn of the 20th century, the amount of water flowing along the Upper Colorado River has declined by about 20%. Research suggests that half of this decline can be attributed to human-induced climate change.
Most of the river’s streamflow comes from the snowpack of the Upper Colorado River Basin, which stretches across five western US states but is primarily located in Colorado and Utah.
This region has been gripped by a historic “megadrought” for more than a quarter of a century. Nearly half of the megadrought’s intensity over 2000-18 is attributable to climate change, according to a 2020 study.
At the same time, the increasing population in the US south-west has put added pressure on the Colorado River’s water supply. The number of people obtaining some or all of their water from the Colorado system has grown by 15 million (around 60%) since 1992.
Schmidt tells Carbon Brief:
“There’s an ultimate cause of the present water crisis, and there’s a proximate cause. The ultimate cause is a warming climate, a warming planet and a pretty clear correlation between warming conditions and decreased runoff in the Colorado River Basin.
“The proximate cause is that in this messy democratic republic of ours, big policy decisions that match the variability of the climate occur painfully slowly – with intense political negotiations – and only incrementally.”
On 31 July, the US Bureau of Reclamation, which manages water resources in the western US, released an environmental impact statement on its proposed post-2026 strategy for managing Lakes Powell and Mead. The strategy itself has not been released yet.
Schmidt notes that the statement does appear to give the Bureau flexibility to “respond to crisis” by reducing the delivery of water to several states. However, he adds:
“They acknowledge it won’t work if we just stay critically dry, and of course every climate model for the 21st century, especially with a continually warming planet, says that that’s exactly what’s going to happen.”
