Climate change, causes and impacts

Space technology investigates large-scale changes to Africa's climate — Last modified May 22, 2015 08:22
University of Leicester researchers map climate and human impacts on Africa's land resources using satellite mapping technology
The green lungs of our planet are changing — Last modified May 20, 2015 08:48
Are leaves and buds developing earlier in the spring? And do leaves stay on the trees longer in autumn? Do steppe ecosystems remaining green longer and are the savannas becoming drier and drier? In fact, over recent decades, the growing seasons have changed everywhere around the world. This was determined by a doctoral candidate at the Goethe University as part of an international collaboration based on satellite data.
Interaction of ocean oscillations caused 'false pause' in global warming — Last modified May 18, 2015 09:25
The recent slowdown in climate warming is due, at least in part, to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate system. They do not signal any slowdown in human-caused global warming.

Climate scientists tackle ‘unfinished business’ — Last modified March 02, 2015 07:56
The so-called “global warming hiatus” since 1998, which has seen global mean surface temperatures fail to match the rise projected by most climate models, has attracted attention from both climate scientists and climate sceptics alike. Now, scientists from Germany and the UK have investigated why the models haven’t replicated real life over this timeframe.
UF/IFAS study: Wheat yield to decline as temperatures increase — Last modified March 02, 2015 07:50
For every degree Celsius that the temperature increases, the world stands to lose 6 percent of its wheat crop, according to a new global study led by a University of Florida scientist. That's one fourth of the annual global wheat trade, which reached 147 million tons in 2013.
Small volcanic eruptions are key to warming hiatus — Last modified March 02, 2015 07:49
Sulphur dioxide hurled in vast amounts from volcanoes is known to cool the atmosphere, but now scientists have identified how even small eruptions have a big effect on climate.

New research outlines global threat of smoldering peat fires — Last modified January 19, 2015 08:52
The natural disaster plays out like a movie script - ash falling from the sky, thick smoke shutting down airports and businesses across the globe, and uncontrollable fires burning for days and weeks.

More trees and more vigorous vegetation growth may not soak up atmospheric carbon, according to new research.
Looking at El Niño's past to predict its future — Last modified January 12, 2015 09:03
The El Niño Southern Oscillation is Earth's main source of year-to-year climate variability, but its response to global warming remains highly uncertain.
New study explains the role of oceans in global 'warming hiatus' — Last modified January 12, 2015 09:01
New research shows that ocean heat uptake across three oceans is the likely cause of the 'warming hiatus' – the current decade-long slowdown in global surface warming.

Climate change could cut West African sorghum yields by a fifth — Last modified December 04, 2014 11:43
In recent decades the Sahel region of West Africa has turned from dusty brown to lush and leafy green. It’s a far cry from the drought conditions that brought famine and crippled the region from the late 1960s to the early 1980s. But the current green and plentiful landscape does not look set to last. A study in Environmental Research Letters (ERL) indicates that by 2060 climate change is likely to cause the Sahel to revert to its dusty state, with droughts equivalent to those experienced in the 1970s.
Climate change set to boost Sumatran wildfires — Last modified December 04, 2014 11:41
October is a worrying month for firefighters on the Indonesian island of Sumatra. As the dry season draws to a close, wildfires spring up all too easily, often resulting in the destruction of vast tracts of rainforest. Now, a study has revealed that climate change is making the problem significantly worse.
Mixed outlook for primary production in warmed climate — Last modified December 04, 2014 10:21
Scientists in the US have predicted that gross primary production – the synthesis of organic compounds, mainly in plant matter, from carbon dioxide – will become limited in a warmed climate, despite having also found that the optimal temperature for the process will rise. According to the researchers, the results highlight the importance of accounting for temperature extremes in climate modelling.
