Arctic warming is splitting Siberia into two climate zones, risking methane release

Leave a Comment / Climatology, Earth Science /

New research suggests that Arctic warming is creating two different climate patterns in Siberia that could lead to rapid increases in methane emissions. Western Siberia is becoming wetter because of rising temperatures and moisture from the North Atlantic, while eastern Siberia is becoming drier and more vulnerable to wildfires. The Yenisei River separates these two […]

Global warming is disrupting the connection between two major oceans

Leave a Comment / Climatology, Earth Science /

Changes in one ocean can have effects far beyond its own waters. For centuries, climate shifts in the tropical Pacific have been carried through the atmosphere, affecting temperatures in the Indian Ocean thousands of kilometers away. It is like a long-distance climate exchange between two vast ocean systems. The Indian Ocean’s Influence on Global Weather

Earth’s oceans hit record-high temperatures, and it’s getting worse

Leave a Comment / Climatology, Earth Science /

Average ocean temperatures reached a record 21.10°C (69.98°F) on August 22, according to the European Union’s Copernicus Climate Change Service (C3S). While that temperature is far below that of a warm bath, it marks the highest global ocean temperature recorded since C3S began collecting data in 1979.

The world’s fastest-warming continent bakes beneath a record-breaking heat dome

Leave a Comment / Climatology, Earth Science /

Europe, gripped by a record-breaking heatwave, is warming faster than any other continent and extends into the rapidly heating Arctic. Britain, Ireland, and France have already set new May temperature records, with even more extreme heat expected in the days ahead. A heat dome is driving the scorching conditions, trapping a mass of hot air

As Antarctic Ice Melts, Mercury Is Released Into the Ocean

Climatology, Earth Science, Uncategorized /

Over the past two centuries, Antarctica has accumulated significant amounts of mercury pollution, despite efforts to preserve the continent’s largely untouched environment. Mercury occurs naturally through volcanic activity and the weathering of rocks. However, human activities such as fossil fuel combustion and mining have greatly increased mercury levels in the environment. Antarctica’s Ice Has Trapped

Arctic Ocean crosses a tipping point with little chance of recovery

Climatology, Earth Science /

A new study suggests that the rapid loss of Arctic sea ice is causing a significant decline in nitrate, a vital nutrient for plankton and the wider marine ecosystem. Scientists warn that this could affect fish, seabirds, and marine mammals while reducing the Arctic Ocean’s ability to absorb atmospheric carbon. Melting sea ice exposes shallow

Scientists warn that oxygen levels in Earth’s waters are quietly declining

Climatology, Earth Science /

Scientists from UC San Diego’s Scripps Institution of Oceanography warn that declining oxygen levels in oceans and freshwater systems could push Earth beyond a safe ecological limit, with some impacts lasting centuries. The review examines aquatic deoxygenation, the decline of oxygen in oceans and freshwater systems, and its effects on the nine Earth system processes

Scientists Create Artificial Cloud to Advance Rain Research

Climatology, Earth Science /

Dutch scientists created an artificial cloud in a glass chamber to study rain formation and explore uses in climatology and drought prevention. Miniature Cloud Experiment Replicates the Water Cycle Researchers simulated condensation conditions on a small scale until droplets combined and fell as raindrops. This scaled-down version of a natural process successfully replicated part of

Air Pollution Cuts in East Asia May Have Sped Up Global Warming

Climatology, Earth Science, Environmental Science /

A new study published Monday (July 14) in Communications Earth and Environment reveals that efforts to reduce air pollution in East Asia have contributed to a faster pace of global warming. Global warming—primarily driven by greenhouse gas emissions—has been accelerating over the past 15 years, causing record-high surface temperatures. During this same period, East Asian
