A study of 2.7 billion-year-old micrometeorites reveals that the early atmosphere likely contained between 25-50% CO2, leading to a cooler climate with evidence of glaciation. This finding suggests lower nitrogen levels in the ancient atmosphere, allowing for a modest greenhouse effect.
A research team from Berkeley Lab tracked a rise in methane's warming effect over 10 years, confirming its importance as a greenhouse gas. The study used highly calibrated measurements to isolate the changing greenhouse effect of methane and found it began to rise in sync with concentrations in 2007.
A NASA-funded study reveals that higher northern latitudes are getting warmer, leading to a shift in the growing season and changes in vegetation growth. Temperatures at northern latitudes now resemble those found 250-430 miles south, with large patches of vigorously productive vegetation spanning over 3.5 million square miles.
A recent study published in Natural Climate Change reveals a significant reduction in temperature and vegetation seasonality over northern latitudes. As snow and ice cover diminished, temperatures increased at different rates during the four seasons, causing this region to resemble areas farther south in terms of vegetation patterns.
A NASA study reveals that carbon dioxide plays a crucial role in regulating Earth's temperature, accounting for 25% of the greenhouse effect. The research demonstrates that without non-condensing greenhouse gases like carbon dioxide, water vapor and clouds cannot sustain the planet's greenhouse effect.
West-Siberian peatlands have counteracted the greenhouse effect by storing more CO2 than releasing methane over the past 10,000 years. A new calculation method reveals non-drained peatlands will become crucial net storage areas for atmospheric greenhouse gases even under global warming.
A new theoretical model helps explore the fate of CO2 injected into oceans under various temperature and pressure conditions. Liquid CO2 would need to be injected to a depth of at least 800 meters to keep it from escaping, according to Zhang's model.
Researchers led by Graham Bell discovered that increased carbon dioxide concentrations negatively impact algae growth, disproving the notion that plants absorb extra CO2. The study's findings have implications for all plant species, including agricultural ones, as fossil fuel emissions continue to rise.
A PhD student developed a method to filter water vapor information from satellite data, enabling accurate predictions of the greenhouse effect. The research is important for understanding the complex influence of water vapor in the atmosphere and its impact on global temperatures.
Scientists have combined satellite measurements with model calculations to demonstrate that atmospheric aerosols increase cloud brightness, leading to greater reflection of sunlight and potential cooling of the climate. This effect should be accounted for in assessing global climate change.
