A team of researchers from the National Centers for Environmental Information (NCEI) of National Oceanic and Atmospheric Administration (NOAA) and LMI has performed a study which revealed that the speed of global warming over the last 15 years of this century has been as fast or faster when compared to the rate seen over the last half of the 20th century. The study, which has been published online in the journal Science, contradicts the idea that there has been a hiatus or slowdown in the rate of global warming over the past few years. The researchers used the new global surface temperature data to arrive at this conclusion.
A research team from Oregon State University has discovered that reservoirs on the Klamath River contain harmful algal blooms that are capable of travelling over 180 miles along the lower parts of the river in just a matter of days. These blooms are unaffected while travelling via hydroelectric turbines and ultimately lead to unsafe water conditions downriver in northern California.
For decades, scientists have relied on an established formula to measure the impact of greenhouse gas emissions on climate change.
How light of different colours is absorbed by carbon dioxide (CO2) can now be accurately predicted using new calculations developed by a UCL-led team of scientists. This will help climate scientists studying Earth's greenhouse gas emissions to better interpret data collected from satellites and ground stations measuring CO2.
The cement industry is one of the largest sources worldwide of carbon emissions, accounting for around five per cent of global emissions. New technologies being developed by the Norwegian University of Science and Technology may help substantially lower these emissions.
With warming summer temperatures across Alaska, white spruce tree growth in Interior Alaska has declined to record low levels, while the same species in Western Alaska is growing better than ever measured before.
Variations in the amount of oxygen in Earth’s atmosphere significantly altered global climate throughout the planet’s history. Efforts to reconstruct past climates must include this previously overlooked factor, a new University of Michigan-led study concludes.
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It's the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest challenges for mountaineers.
Many species are migrating toward Earth's poles in response to climate change, and their habitats are shrinking in the process, researchers say. Two new reports focusing on marine organisms, which have been moving pole-ward at higher rates than terrestrial creatures, show how factors, including those not directly related to climate change, are limiting the ranges of corals and fish.
A new record of past climate change shows that a warm climate in northern Europe can be hit by a sudden cooling associated with an interruption of the North Atlantic Ocean circulation and the Gulf Stream. This is shown in a new study published in Quaternary Science Reviews, investigating the development of northern European climate about 120 thousand years ago.
