00:00Welcome back. There has been little good news for glaciers so far in 2025.
00:05A series of reports all reached the same conclusion.
00:09Climate change is melting these bodies of ice at alarming rates. Let's see.
00:15The year got off to a bad start for the world's glaciers.
00:19A major report published in early February showed climate change was melting the world's mountain glaciers faster than ever.
00:25They are now shrinking at more than twice the speed of the early 2000s, according to the study.
00:31Researchers said the world has lost more than 7 trillion tons of ice from mountain glaciers since 2000.
00:38In 2023, the world's glaciers lost more than 600 billion tons of ice.
00:44Some of the fastest melts are in Alaska, and the smaller glaciers in Central Europe, such as the Alps, have shrunk the most proportionally.
00:52What are they doing at the moment, and what does that tell us about them?
00:58And as they say, they're losing 400 billion tons of ice.
01:01New research showed that even limiting global temperatures to 1.5 degrees Celsius under the Paris Climate Agreement won't protect many heavily populated coastlines.
01:13The study by an international group of researchers says the target should instead be closer to 1 degree to avoid losses from the polar ice sheets.
01:22According to Durham University's Chris Stokes, the lead author of the report, the mass of ice lost from these ice sheets has quadrupled since the 1990s.
01:35He says that with current warming levels of 1.2 degrees above pre-industrial levels, the planet is losing around 370 billion tons of ice per year.
01:44The figures from the report are taken from the latest Intergovernmental Panel on Climate Change Assessment.
01:50With migration already a thorny issue around the globe, scientists say sea level rise will in the future make the mass movement of people inevitable.
01:58A healthy glacier is considered dynamic, generating new ice as snow falls on it at higher elevations while melting at lower altitudes.
02:09The losses in mass at lower levels are compensated by gains above.
02:14As a warming climate pushes melting to higher altitudes, this process stalls.
02:20This lack of dynamic regeneration is the most likely cause behind the emergence and persistence of holes, seemingly caused by water turbulence at the bottom of the glacier, or by air flowing through gaps that appear inside the blocks of ice.
02:33As 2025 comes to a close, the alarming rate at which glaciers are melting serves as a stark reminder of the intensifying impacts of climate change.
02:46Reports reveal that mountain glaciers are shrinking faster than ever, and the loss of ice from polar regions continues to accelerate.
02:54Despite efforts to limit global warming to 1.5 degrees Celsius, the reality is that even this target may not protect vulnerable coastlines from rising sea levels.
03:05With mass ice loss projected to increase, migration due to environmental changes will become an unavoidable challenge.
03:12As we approach 2026, urgent action to curb global warming remains critical to mitigate further irreversible damage to our planet's ice reserves.
