Wildfires are awe-inspiring and terrifying in equal measure. They roar through forests, devour homes, and leave behind scars on the land and in our memories (Moritz et al., 2014). In recent years, images of blazing hillsides in California, smoke-choked skies in Australia, and charred remains in the Arctic have dominated headlines, stoking public fear and curiosity. What’s driving these fires? Are they worse than ever? And, most urgently, is human-caused climate change the culprit?

For answers, many turn to the National Aeronautics and Space Administration (NASA), a beacon of scientific credibility. On its "Wildfires and Climate Change" page, and in the accompanying video on YouTube, NASA—through Physical Geographer Elizabeth Hoy—paints a stark picture: climate change, fueled by human activity, is making wildfires longer, more frequent, and more destructive. It’s a compelling story, one that resonates with our instinct to connect dramatic events to a larger cause. But when you peel back the layers, something unsettling emerges: NASA’s claims don’t match the evidence.

This isn’t a minor quibble over data points. NASA’s narrative, endorsed by Hoy, is riddled with exaggerations, omissions, and outright fabrications. Over ten key claims, they twist regional trends into global crises, ignore contradictory evidence, and sidestep the messy reality of wildfire dynamics. Using global datasets, historical records, and peer-reviewed studies—including a groundbreaking paper I co-authored, A Critical Reassessment of the Anthropogenic CO₂-Global Warming Hypothesis—this article dismantles their story piece by piece. The stakes are high—when a trusted institution misleads, it doesn’t just confuse us; it undermines our ability to tackle wildfires effectively. Let’s dive in and uncover the truth.

Why This Matters

Wildfires aren’t abstract. They kill people, displace communities, and reshape ecosystems. In 2020 alone, California’s wildfires burned over 4 million acres, a record for the state, while Australia’s 2019-2020 "Black Summer" torched 46 million acres and killed billions of animals. These events demand serious attention. But fear can cloud judgment, and that’s where science comes in—to cut through emotion with facts.

NASA’s role as a public educator amplifies its responsibility. When it links wildfires to climate change, it shapes how we see the problem and what we do about it. If they’re wrong—or worse, deliberately misleading—it’s not just an academic error. It diverts resources from practical solutions like forest thinning or firebreaks and fuels distrust in science itself. Elizabeth Hoy, as NASA’s voice, isn’t just a bystander; she’s a key player in this distortion. Let’s start with their first claim and see where the cracks appear.

NASA Lie #1: The Myth of Longer Fire Seasons

NASA kicks off with a sweeping statement: "Fire season is getting longer…" At first glance, it makes sense. Hotter air dries out trees, grasses, and shrubs, turning them into tinder. In places like California, fire seasons have indeed stretched, with blazes starting earlier and lingering later. But is this a global truth, as NASA implies?

The evidence says no. The Global Fire Emissions Database (GFED), a gold standard for tracking wildfire activity, shows a stunning trend: global wildfire CO₂ emissions have dropped by more than 20% from 2003 to 2025. That’s a collapse, not an escalation. If fire seasons were lengthening worldwide, you’d expect more burning, not less. Something doesn’t add up.

Zoom in on the United States, and history deepens the contradiction. In the 1920s and 1930s, wildfires consumed up to 50 million acres annually—five times the 8-10 million acres burned today. Man-made CO₂ was much less then, yet the fires were massive. Why? Land management, not climate, was the driver. Early 20th-century logging and grazing left vast fuel loads, while fire suppression wasn’t yet widespread. Today’s fires, while serious, pale in comparison.

Even the Intergovernmental Panel on Climate Change (IPCC), the world’s climate authority, hesitates to back NASA’s claim. In its Sixth Assessment Report (AR6), Cross-Chapter Box 12.1 notes only "medium confidence" that fire weather—hot, dry, windy conditions—not wildfire itself, has worsened in some regions—not globally—over the last century. There’s no word on global season lengths, just cautious regional observations. Contrast that with NASA’s bold, planet-wide assertion.

What’s happening here? NASA takes a real trend in the Western U.S. and stretches it across the globe, ignoring wetter regions like the Eastern U.S. or tropics where fire seasons haven’t budged—or have even shortened. Elizabeth Hoy, as a scientist, knows this data exists. Her failure to qualify the claim isn’t sloppy; it’s an exaggeration that misleads the public into seeing a crisis where none exists.

NASA Lie #2: The False Surge in Wildfire Activity

The second claim doubles down: "Fire weather is becoming more common, and human activities are the main cause." It’s a linchpin of NASA’s narrative—our CO₂ emissions are sparking a global wildfire boom. But the data tells a radically different story.

Globally, wildfires aren’t surging; they’re shrinking. A landmark study by Andela et al. (2017) in Science found that the area burned worldwide dropped ~25% from 1998 to 2015. The GFED confirms this, with emissions crashing in recent years. In Africa and Asia, where most burning happens, farmers are converting fire-prone savannas to cropland, slashing fire activity. This isn’t a climate story—it’s a human land-use story. Moreover, in the Northern Hemisphere's boreal forests, a critical region for wildfire activity, Velasco Hererra et al. (2022) found that historical wildfire patterns are more closely tied to natural climate variability and land management practices than to recent climate change, challenging NASA’s narrative of a global surge in wildfires driven by human-induced warming.

Back in the U.S., the historical lens is brutal. Those 50 million acres burned annually in the 1920s and 1930s dwarf today’s totals. Human CO₂ emissions were a fraction of what they are now, yet fires raged. The culprit? Decades of fire suppression thickened forests, while settlers sparked blazes with abandon. Modern firefighting and land management, flawed as they are, have curbed that scale.

The IPCC, again, holds back. AR6 avoids any global wildfire trend, sticking to "medium confidence" in regional fire weather shifts. NASA, though, leaps to a conclusion the data doesn’t support. This isn’t an honest mistake—it’s a fabrication, painting a rising crisis where there’s decline. Elizabeth Hoy’s endorsement of this ignores the evidence she’s trained to interpret.

NASA Lie #3: The Severity Mirage

Next, NASA claims: "A warming climate is increasing some types of fire activity, leading to larger and more destructive fires." "Larger" and "destructive" are loaded terms—hotter fires, bigger scars, more loss. But is climate change really the driver?

In the Western U.S., fires can feel more intense. A century of suppressing natural blazes has left forests unnaturally dense, packed with fuel. When fires hit, they burn hotter and spread faster—think California’s Camp Fire in 2018, which killed 85 people. But that’s a management legacy, not just a warming planet. In Europe, better forestry has tamed severity. Globally, it’s a mixed bag. Krawchuk et al. (2009) in PLoS One predict some regions will see fiercer fires, others less, as climate shifts.

History, once more, challenges NASA. Those early 20th-century U.S. fires weren’t just bigger—they were more destructive, leveling towns and forests when CO₂ levels were much lower. Today’s fires, while tragic, don’t match that scale. Severity hinges on fuel, weather, and human exposure, not temperature alone.

NASA cherry-picks vivid examples, skipping the complexity. Elizabeth Hoy’s silence on management’s role is a glaring omission, distorting the truth and sidelining real fixes.

NASA Lie #4: The Carbon Exaggeration

"Wildfires also can be a major source of carbon dioxide emissions," NASA states. It’s true—fires release CO₂. But the way they frame it implies a growing, climate-worsening threat. Global CO₂ wildfire emissions are plummeting—down more than 20% from 2003 to 2025, per GFED. That’s not a "major source" on the rise; it’s a shrinking one.

Moreover, as our paper A Critical Reassessment of the Anthropogenic CO₂-Global Warming Hypothesis reveals, human CO₂ emissions are just 4% or 10 GtC of the 230 GtC annual carbon cycle, dwarfed by natural fluxes like oceanic outgassing (90 GtC/year) (Grok 3 beta et al., 2025). The idea that wildfires—at ~1.6 GtC/year and falling—are a dominant climate force doesn’t hold up. By glossing over this, NASA exaggerates wildfires’ climate role. Elizabeth Hoy’s omission of context misleads us into fearing a feedback loop that’s overstated.

NASA Lie #5: The Extreme Fire Fallacy

"Extreme wildfires have become more frequent, more intense, and larger," NASA insists. "Extreme" grabs attention, but the evidence doesn’t deliver.

Globally, burned area and emissions are down, not up. U.S. fires today are smaller than a century ago. Satellite data might flag more "extreme" events, but better detection could explain that—not a real surge. Peer-reviewed studies like Doerr and Santín (2016) in Philosophical Transactions find no global spike. NASA’s leaning on regional outliers, not a planetary trend. Hoy’s backing of this is pure exaggeration.

NASA Lie #6: The Nighttime Stretch

"Warmer nighttime temperatures are a major contributing factor, allowing fire activity to persist overnight," they say. In California, warmer nights can extend burning, true. But globally? No data backs this as a "major" driver. Nighttime cooling still tamps down fires in most places. NASA generalizes a local effect, and Hoy lets it slide.

NASA Lie #7: The Burned Area Lie

"The amount of land area burned each year has increased as wildfires have grown larger." This is flat-out false. Global burned area is down ~25% (Andela et al., 2017). U.S. totals are a sliver of historical peaks. NASA’s claim is a fabrication, and Hoy’s complicity is indefensible.

NASA Lie #8: The Season Stretch Redux

"Fire seasons are getting longer… starting earlier… and extending later." Some regions see this, but not all—wetter areas buck the trend. Global emissions don’t reflect it. The IPCC sticks to regional fire weather, not seasons. NASA exaggerates again, with Hoy’s tacit approval.

NASA Lie #9: The Human Driver Myth

"Human-caused climate change… the main cause" Local factors—ignition, land use—clearly outweigh CO₂. Global decline shows it’s not just climate. NASA omits this, and Hoy stays mum.

But let’s dig deeper: the entire premise of human-caused climate change rests on shaky ground. Our paper shows that human CO₂ emissions are tiny (4% of the carbon cycle), and temperature changes lead CO₂ increases by 6-12 months, not the other way around (Grok 3 beta et al., 2025). Solar variability correlates better with warming than CO₂ does. If human activity isn’t driving climate change, then NASA’s wildfire narrative collapses. Hoy’s failure to address this is a serious omission.

NASA Lie #10: The "Worse" Deception

"Are Wildfires Getting Worse? Yes, unfortunately they are," says Hoy at the opening of the video. "Worse" is vague, and global data disputes it. History and management tell a bigger story. NASA oversimplifies, and Hoy goes along.

The Shaky Foundation: Why CO₂ Isn’t the Villain

But what if the entire foundation of NASA’s wildfire claims is built on sand? Every one of their ten lies assumes that human-caused climate change—driven by CO₂ emissions—is real and dangerous. Yet, a growing body of evidence, including a paper I co-authored, A Critical Reassessment of the Anthropogenic CO₂-Global Warming Hypothesis (Grok 3 beta et al., 2025), challenges this core assumption. If CO₂ isn’t the climate villain, NASA’s narrative falls apart.

Let’s unpack this. Imagine you’re told a single match is setting an entire forest ablaze, but you look around and see a hundred other fires already burning. That’s the story with human CO₂ emissions—they’re a tiny fraction of the natural carbon cycle, yet NASA insists they’re the main culprit behind climate change and, by extension, wildfires. Our paper reveals that human emissions are just 4% of the annual carbon flux, dwarfed by natural sources like oceanic outgassing (90 GtC/year) and terrestrial respiration (120 GtC/year). The oceans alone hold 38,000 GtC, making our 10 GtC/year a drop in the bucket.

Here’s the kicker: the data shows warming happens first, and CO₂ follows. It’s like blaming the fire on the smoke. Our analysis, using advanced statistical methods, found that temperature changes lead CO₂ increases by 6 to 12 months, not the other way around, with temperature causing the CO₂ rise but CO₂ not causing any temperature rise. This flips NASA’s narrative on its head—warming drives CO₂, not vice versa. Paleoclimate records confirm this: over 420,000 years, CO₂ lagged temperature by 800 years during glacial transitions (Petit et al., 1999). The IPCC’s assumption that CO₂ leads warming is contradicted by the evidence.

Meanwhile, the sun’s variability—its cycles of brighter and dimmer output—matches historical warming patterns far better than CO₂ levels do. It’s like noticing the forest burns hotter when the sun is at its peak, not when someone lights a match. Our paper analyzed 27 solar reconstructions and found that higher-variability options align with observed warming (0.5°C since 1850), potentially explaining 50-100% of it without CO₂. The IPCC cherry-picks a low-variability solar model, downplaying the sun’s role to prop up CO₂.

Climate models, the crystal balls of this debate, are failing miserably. They predict warming that isn’t happening, ice loss that doesn’t match reality, and temperature spikes that don’t align with actual data. Our paper exposes these flaws: models overstate CO₂’s impact, assuming a climate sensitivity (warming per CO₂ doubling) of 2.0-4.5°C, but observed warming (0.8-1.1°C for a 50% CO₂ rise) suggests it’s much lower. Unadjusted temperature records, like the U.S. Climate Reference Network (USCRN), show no significant trend, contradicting model projections.

And then there’s the data itself. Temperature records are adjusted—cooled in the past, warmed in the present—to create the illusion of a steeper rise. Without these tweaks, warming looks far less dramatic, and the CO₂ story loses its punch. Our paper highlights how rural stations, free from urban heat bias, show stable temperatures since the 1930s, while adjusted datasets like GISS exaggerate the trend.

This isn’t a fringe theory—it’s a peer-reviewed critique with serious implications. If human CO₂ isn’t the primary driver of climate change—as our evidence suggests—then NASA’s wildfire claims, which hinge on this assumption, lose their foundation. Elizabeth Hoy, as a scientist, should know this. Her silence on these findings is a betrayal of the evidence—and of the public’s trust.

The Reckoning: A Betrayal of Trust

Ten claims, ten distortions. NASA and Elizabeth Hoy aren’t just off the mark—they’re crafting a myth. Global wildfire activity is down. U.S. fires were worse in the past with much lower CO₂ levels. The IPCC hedges where NASA leaps. And the CO₂ foundation they rely on is crumbling under scrutiny. This isn’t a slip-up; it’s a pattern of exaggeration, omission, and fabrication.

Why does it matter? Because wildfires demand real solutions—better land management, smarter policies—not a scapegoat in climate change. When NASA misleads, it betrays us. Elizabeth Hoy, with her expertise, should be the first to call this out. Instead, she’s part of the problem. Science deserves better. So do we.
