Jan 29, 2021 · According to the study, ice melt over the past three decades has steadily increased — in the 1990s, there was an average global ice melt of 0.8 trillion tonnes per year; by 2017, there was an average of 1.3 trillion tonnes per year. In total, the rate of ice loss has increased by 65 percent between 1994 and 2017.
Sep 21, 2021 · The energy-storing capabilities of ice could provide a more efficient, climate-friendly approach to cooling. Ice thermal energy storage like this can also address the need for storing surplus renewable energy to balance out the grid at times of peak demand. Applications range from district heating and cooling to power generation.
Feb 24, 2020 · In some places, the ice reaches the coast and floats on the ocean surface, forming an ice shelf. The boundary between ice resting on the land surface (or the sea floor in the case of a marine ice sheet) is called the “grounding line”. The grounding line is where water stored in the ice sheet returns to the ocean.
Oct 7, 2021 · Ice loss from the Antarctic and Greenland ice sheets was the largest contributor to sea level rise in recent decades. Even if all greenhouse gas emissions ceased today, the heat already in the ocean and atmosphere would cause substantial ice loss and a corresponding rise in sea levels. But exactly how much, and how fast, remains unclear.
Dec 1, 2021 · The Greenland ice sheet lost around 166bn tonnes of ice over the 12-month period ending in August 2021. It's the 25th year in a row where Greenland has lost more ice than it gained. A cool and wet early summer delayed the onset of the main melt season, but a heatwave in late July subsequently brought higher ice loss.
Jan 23, 2020 · Since the 1970s, we have lost 75% of the volume of Arctic summer sea ice. The Arctic affects the jet stream, causing extreme weather all over the world. The Arctic used to be white but now it's turning blue, and absorbing more heat in a feedback loop.
May 11, 2017 · And rather than diseases being released by melting ice, some argue that as Earth warms northern countries will become more susceptible to outbreaks of "southern" diseases like malaria, cholera and dengue fever, as these pathogens thrive at warmer temperatures.
Nov 18, 2019 · Researchers from the National Oceanic and Atmospheric Administration (NOAA) recorded a significant decrease over time in both the extent of ice cover and its thickness. In the 1980s, the average March sea ice was more than 15.5 million square kilometres, but in recent years the average is closer to 14 million square kilometres.
May 4, 2021 · The study finds that, between 2000 and 2019, mass loss from glaciers was 47% higher than from the Greenland ice sheet (GIS) and more than twice that of the Antarctic ice sheet (AIS) The authors also note that, while glacier mass loss “distinctly accelerated” over the entire 2000-19 period, the mass loss from ice sheets decelerated since a peak in the mid-2010s.
Dec 22, 2021 · Sea ice continues to decline; the post-winter sea ice volume in April 2021 was the lowest since record-keeping began. The Arctic Report demonstrates “consistent, alarming and undeniable” alterations, including greening tundra and rising surface temperatures.
