Monday was Earth Information Day at COP30. Earth Information Day is a plenary briefing where all the UNFCCC science groups, including the World Meteorological Organization, the World Climate Research Programme, and others brief the COP delegates on the state of climate science. As the UNFCCC “information note” explains:
Systematic observation is vital for monitoring and understanding weather and climate status and trends to inform climate action. Earth observation networks, including in-situ and satellite-based observations, provide relevant data for forecasting and modelling climate change, response mechanism, risk management including supporting relate services such as early warning systems (EWS). Within the UNFCCC process, the annual Earth Information Day (EID) provides an opportunity for Parties to engage with the systematic observation community to share and understand latest information, trends and projections of the climate to inform negotiations and wider decision-making. Through EID, messages on closing observation gaps, enhancing systematic observations and related initiatives, and advancing cooperation have been recognized.
As a highlight of COP30, which is being dubbed “the COP of Truth,” Earth Information Day 2025 delivered some hard truths. It featured scary science, even scarier policy, and interesting takeaways for state and local governments.
UNFCCC Executive Director Simon Steil kicked off the discussion by pointing out that “science and data give us resilience,” not just bad news. Observations are more important than ever, but unfortunately our observation systems are under strain.
WMO executive director Celeste Saulo WMO reported that the past three years have been the warmest 3 yrs on record, and have delivered destructive weather on a daily basis. Science not only warns us, but also—and increasingly importantly—equips us. She argued the need for more and better bridges between science and policy. She also pointed out that scientists are increasingly able to attribute weather events to climate change, an important condition for policy action.
Ten years after the Paris Agreement with its core “1.5 C” ceiling for global C02 emissions—the maximum emissions allowable to avoid the worst climate impacts by 2100—and for the first time, every speaker has agreed there is virtually no chance of avoiding “overshoot.” The common trope now is to keep the overshoot as low as possible and bring emissions back below 1.5C as quickly as possible, certainly by the end of the century.
The even more concerning common theme at EID was the ill-timed, ongoing global disinvestment from science, especially in meteorology. At a time when humanity is experiencing ever-increasing disastrous weather, now would seem to be a uniquely poor moment to scale back funding for the systems that provide early warnings to local communities—but funding for the WMO is falling short because countries including the US have not honored their pledges, and the organization is mounting an investor campaign while also looking at staffing cutbacks. Read more about the bond issue.
For states like Texas that experience frequent severe weather impacts, early warning systems—undergirded by the best available science and technology—are critical, especially for sudden-onset events like the July 4 floods in the Texas Hill Country. Reducing the availability of information now would be a cruel irony that would cost more in human suffering than it would save in funding.
But while global finance struggles, it’s also a key moment for subnational groups to step up. As home to some of the top research institutions in the country, Texas is well-positioned to be a leader, not only in diagnostic science, but in life-saving public climate information.

This update from COP30 doesn’t just deliver facts it pulses with urgency, with the quiet heartbreak of knowing we’re running out of time. Earth Information Day becomes more than a briefing; it’s a mirror held up to humanity, reflecting both our brilliance and our blind spots. What makes it so deeply human is the tension between what we know and what we choose to do. The science is clear, the warnings louder than ever, and yet the systems meant to protect us are being starved. Still, there’s a thread of hope thin but strong in the call for local action, for communities to rise where global powers falter. Because in the end, resilience isn’t abstract. It’s personal. It’s now.
