Rising CO2 Levels Are Reflected In Human Blood. Scientists Don't Know What It Means
Our findings are not suggesting people will become suddenly unwell when atmospheric CO reaches a certain level. What the data show is a signal that warrants attention.

Atmospheric CO2 Levels Reach 8,00,000 Year-High In 2023: Report
The World Meteorological Organization's (WMO) State of the Climate report said the past 10 years (2015-2024) were the warmest on record, with each of the last eight years setting new highs for ocean heat content.

Greenhouse Gas is Rising Rapidly in Atmosphere Due to Human Activities, Highlights New Report
Methane levels, which are 80 times more potent than CO2 in the short term, are rising at an unprecedented rate. Human activities, such as agriculture and fossil fuel extraction, contribute significantly to this surge. Despite global efforts, including the 2021 Global Methane Pledge, methane emissions continue to climb. This trend threatens climate ...

Antarctica Was Last Ice-Free 34 Million Years Ago: What Triggered This Climate Shift?
Antarctica, which is nearly four times the size of the United States, was not always covered in ice. The last time it was ice-free was 34 million years ago during the Eocene-Oligocene boundary. At that time, global temperatures were higher, and carbon dioxide levels in the atmosphere were much higher than today. However, a significant drop in CO2 l...

Earth's Atmosphere More Sensitive to CO2 Emissions Than Previously Believed, Study Finds
A new research reassessing the atmosphere’s sensitivity to carbon dioxide (CO2) helps narrow down the range of temperature rise caused by doubling of CO2 levels since pre-industrial times.

Carbon Dioxide Levels Grew At Record Pace In 2016, UN Says
The amount of carbon dioxide in the earth's atmosphere grew at record rate in 2016 to a level not seen for millions of years, potentially fueling a 20-metre rise in sea levels and adding 3 degrees to temperatures, the United Nations said on Monday.

CO2 Levels Hit Record High For 30th Year in a Row: World Meteorological Organization
Greenhouse gas levels in the atmosphere reached a record high in 2014 as the relentless fuelling of climate change makes the planet more dangerous for future generations, the World Meteorological Organization said today.

'Time Running Out' as CO2 Levels Hit New High: UN
Atmospheric carbon dioxide concentrations have crossed a new threshold, the UN's weather agency said Monday, highlighting the urgency of curbing manmade, climate-altering greenhouse gases.
