Increasing Public Knowledge about Energy Issues May Help Improve Energy-Saving Behaviours

Increasing public knowledge and understanding about energy issues is vital if improved energy-saving behaviours are to be encouraged among individuals and organisations, a study suggests.

Deeper Emissions Cuts Can Limit Climate Change to Less Than 1.5°C, Say Researchers

Limiting temperature rise by 2100 to less than 1.5°C is feasible, at least from a purely technological standpoint, according to the study published in the journal Nature Climate Change by researchers at the International Institute for Applied Systems Analysis (IIASA), the Potsdam Institute for Climate Impact Research (PIK), and others. The new study examines scenarios for the energy, economy, and environment that are consistent with limiting climate change to 1.5°C above pre-industrial levels, and compares them to scenarios for limiting climate change to 2°C.

Savannahs, Shrublands Play Extremely Important Role in Controlling Carbon Levels

Tropical rainforests have long been considered the Earth's lungs, sequestering large amounts of carbon dioxide from the atmosphere and thereby slowing down the increasing greenhouse effect and associated human-made climate change. Scientists in a global research project now show that the vast extensions of semi-arid landscapes occupying the transition zone between rainforest and desert dominate the ongoing increase in carbon sequestration by ecosystems globally, as well as large fluctuations between wet and dry years. This is a major rearrangement of planetary functions.

Arctic Warming Linked with Severe Weather in Other Countries

Professor Edward Hanna and PhD student Richard Hall, from the University of Sheffield’s Department of Geography, are part of a select group of international climate scientists investigating links between Arctic climate change and extreme weather in the northern mid-latitudes.

Better Understanding of Relationship Between Stratosphere-Troposphere Layers Could Boost Climate Change Projections

Long range weather forecasts and climate change projections could be significantly boosted by advances in our understanding of the relationship between layers of the Earth's atmosphere -- the stratosphere and troposphere.

Climate Change Impacts on Water Cycle of Midwestern US Remain Uncertain

Will climate change make the U.S. Midwest drier or wetter during the summer growing season? A new Dartmouth-led study finds that the answer remains uncertain.

Ocean Microbes Could Influence Cloud Properties and Impact Climate

A factor that determines the properties of clouds that help moderate the planet’s temperature may be decided in the oceans.

Researchers Find Clear Indications of Warming in the Upper Troposphere

Researchers have published results in Environmental Research Letters confirming strong warming in the upper troposphere, known colloquially as the tropospheric hotspot. The hot has been long expected as part of global warming theory and appears in many global climate models.

Climate Change Contributes to Drop in Ozone Levels

Researchers at the University of Houston have determined that climate change - in the form of a stronger sea breeze, the result of warmer soil temperatures - contributed to the drop in high-ozone days in the Houston area.

Study Estimates Quantity and Form of Organic Carbon Exported by Rivers to the Ocean

Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the removal and long-term storage of carbon, including the world's river systems, which transport decaying organic material and eroded rock from land to the ocean.
