The concentration of carbon dioxide in Earth’s atmosphere has been steadily rising, largely due to human activities and climate change. However, scientists have also observed an increasing difference between seasonal peaks and dips in atmospheric carbon dioxide levels. Previously, researchers believed that these carbon dioxide fluctuations were primarily caused by warming temperatures and rising CO₂ …

After more than five decades since it was first proposed, scientists have finally detected the polar wind, an invisible force influencing how Earth’s atmosphere escapes from the poles. This significant breakthrough was achieved by NASA’s Goddard Space Flight Center’s principal investigator Glyn Collinson and his team, validating a phenomenon as fundamental to our planet as …

A recent analysis of cloud data from the California coast, along with global satellite observations, highlights the significant role of aerosol particles as small as 25–30 nanometers in cloud formation. This challenges previous assumptions and suggests that the climate impact of tiny aerosols may have been underestimated.

The escalating concerns about methane emissions are driving significant attention toward their major sources of methane. A new methane-monitoring satellite has recently been deployed to observe rogue emissions, particularly from the oil and gas sectors, indicating a step forward in tracking this potent greenhouse gas. However, the complexity of methane’s impact on climate extends far …

A comprehensive study recently published in the journal Science reveals that Earth’s current carbon dioxide (CO2) levels, driven by human activity, match those last seen 14 to 16 million years ago, a significant shift from the previously estimated 3 to 5 million years.

The weight of Earth’s atmosphere is a fascinating concept that plays a vital role in sustaining life on our planet. It’s essential to understand atmospheric pressure, which is the force exerted by the atmosphere due to the weight of air molecules pressing down because of gravity. At sea level, this pressure is approximately 101,325 pascals …
