Warmer weather conditions changed the snowpack at exactly the wrong times.<\/p>\n

What extremely rare phenomenon is causing this snow drought<\/strong>?<\/p>\n

How low can you go: A Colorado mystery that has now been explained<\/h2>\n

NASA researchers were tracking the Upper Colorado Basin when they noticed something alarming.<\/p>\n

Snowpack levels crashed 30% below historical averages<\/strong> in weeks.<\/p>\n

Peak runoff arrived 30 days early, effectively ‘stealing’ summer’s water.<\/p>\n

Especially in the western part of the nation<\/strong>.<\/p>\n

The snow didn’t just melt; it vanished via sublimation and record-fast runoff.<\/p>\n

Satellite observation revealed a startling truth<\/strong>.<\/p>\n

Snow cover shrank to record lows across the western United States.<\/p>\n

Researchers discovered a ‘warm snow drought’<\/strong>. This is where it rains instead of snows even at high elevations.<\/p>\n

They were melting differently. This raised a profoundly important question.<\/p>\n

What was causing this new and unexpected reality<\/strong> in Colorado?<\/p>\n

Drop it like it’s hot: Extreme warmth transformed winter storms in Colorado<\/h2>\n

NASA researchers quickly realized much of the West was experiencing a “warm snow drought”.<\/p>\n

Which can happen when precipitation temperatures stay warm for too long<\/strong>.<\/p>\n

This reduced the timeframe for lasting snow accumulation on the mountains.<\/p>\n

In some Western states, the snowpacks were disappearing months earlier than normal.<\/a><\/p>\n

The issue in Colorado became especially worse during March<\/strong> of this year.<\/p>\n

A significant heatwave in the Colorado Basin shattered temperature records.<\/p>\n

According to NASA experts, the basin experienced its warmest March on record<\/strong>.<\/p>\n

Snow cover rapidly melted as the heat arrived.<\/p>\n

But was this climate change<\/strong>? Or something else entirely?<\/p>\n

Climate change is affecting every part of the world.<\/p>\n

From the oceans warming at an alarming rate<\/a>, to the Colorado snowpacks simply vanishing<\/strong>.<\/p>\n

Fresh snow has an albedo of 0.9, reflecting 90% of solar energy. But fewer rainstorms meant that the snow was aging.<\/p>\n

Dust-on-snow events and ‘old’ snow grains absorb solar radiation, accelerating melt by 50%<\/strong>.<\/p>\n

Which accelerates melting even further. Faster melting exposed open ground far earlier than normal.<\/p>\n

But rising temperatures alone could not explain<\/strong> what was happening in Colorado.<\/p>\n

Something else was at play.<\/p>\n

What it was has been explained by environmental experts at NASA<\/a>.<\/p>\n

A forecast that calls for chaos: a rare phenomenon that only happens every 1,000 years<\/h2>\n

NASA<\/a> identified a climate dipole: a seesaw of extreme atmospheric pressure<\/strong>.<\/p>\n

The agency has the technology to study the Earth far more extensively<\/a> than ever before.<\/p>\n

NASA’s technology pointed in one direction: an extremely rare atmospheric pattern<\/strong> called a western U.S. dipole.<\/p>\n

This phenomenon only takes place around every 1,000 years or so. It traps intense heat over the western parts of the nation.<\/p>\n

The East is experiencing something else<\/strong> completely as arctic air plunges into those parts of the country.<\/p>\n

A rare pattern that disrupts storm tracks for months at a time<\/h3>\n

This dipole merged with ‘The Blob’\u2014a massive Pacific marine heatwave<\/strong>.<\/p>\n

sudden stratospheric warming (SSW) disrupted the polar vortex, locking the heat in place. <\/p>\n

That combination would have a profound impact on the West<\/strong> of the nation.<\/p>\n

Climatologists believe this unique and rare overlap of conditions led to the snowpack melting early.<\/p>\n

This 1,000-year event isn’t just a fluke; it’s a preview of the ‘new normal’ for 2050<\/strong>.<\/p>\n

Colorado has astonishing natural beauty that defies the norms<\/a>. <\/p>\n

But its snow system is feeling the effects of a rare combination of extreme events<\/strong>.<\/p>\n

If 1,000-year events are now happening in a single decade, are we witnessing a rare anomaly?<\/p>\n
