Climate change, causes and impacts

Where has climate change altered Europe's rainfall? — Last modified January 15, 2016 15:19
Limited datasets make it difficult to establish whether local changes in rainfall are due to human-induced climate change or natural variation, according to scientists in the UK.
No substantive evidence for ‘pause’ in global warming — Last modified January 11, 2016 08:35
There is no substantive evidence for a ‘pause’ or ‘hiatus’ in global warming and the use of those terms is therefore inaccurate, new research from the University of Bristol has found.
Climate change is driving water cycle speed-up — Last modified December 21, 2015 14:28
The global water cycle is getting faster. Over the last few decades rainfall has become heavier whilst evapotranspiration from terrestrial ecosystems has sped up. Now research reveals that climatic changes are the predominant driver of this accelerating hydrological cycle, and that rising carbon dioxide also plays an important role.
Perfect temperature for economic success – 13C — Last modified December 14, 2015 08:22
From the Guardian. The perfect average temperature for national economic success is 13C (55.4F), academics have discovered. But the fundamental link they have revealed between a country’s economy and its temperature has led them to warn that the costs of unchecked climate change will be many times worse than previously thought.
Scientists identify climate ‘tipping points’ — Last modified December 14, 2015 08:20
An international team of scientists have identified potential ‘tipping points’ where abrupt regional climate shifts could occur due to global warming.

Warming of oceans due to climate change is unstoppable, say US scientists — Last modified December 02, 2015 09:08
From the Guardian. The warming of the oceans due to climate change is now unstoppable after record temperatures last year, bringing additional sea-level rise, and raising the risks of severe storms, US government climate scientists said on Thursday.
Focus on extreme events and the carbon cycle — Last modified November 26, 2015 09:07

Atmospheric changes boost temperature extremes — Last modified November 26, 2015 09:01
In 2010, a heatwave in Russia caused around 55,000 premature deaths, while seven years ealier, extreme high temperatures in Europe led to roughly 70,000 fatalities. Now, a team from the US has assessed how much changes in atmospheric circulation, as opposed to greenhouse-gas concentrations, have contributed to such extreme temperature trends.
One century of climate change equates to 300 years of land-use change — Last modified November 25, 2015 09:55
Humans are having a huge impact on the ecosystems of our planet, either directly – by land-use change – or indirectly, through climate change. Researchers in Germany have found that the area of Earth's ecosystems exposed to at least moderate climate-change impacts in just one century is comparable in size to all of the land transformed by human societies for cropping and pastures.
Drought-induced tree mortality accelerating in forests — Last modified October 21, 2015 09:10
Researchers at Los Alamos National Laboratory have found that drought and heat-induced tree mortality is accelerating in many forest biomes as a consequence of a warming climate in their paper "Darcy's law predicts widespread forest mortality under climate warming," published in the journal Nature Climate Change.
What would it take to limit climate change to 1.5°C? — Last modified September 16, 2015 10:21
A new study analyzes the required climate policy actions and targets in order to limit future global temperature rise to less than 1.5°C by 2100. This level is supported by more than 100 countries worldwide, including those most vulnerable to climate change, as a safer goal than the currently agreed international aim of 2°C.
Dryland plants drive variability of terrestrial carbon sink — Last modified September 16, 2015 10:20
Each year, vegetation on land takes up around one-quarter of the carbon dioxide that man spews out into our atmosphere. And each year the size of that carbon sink varies. Now an international research team has found that semi-arid ecosystems have a big influence on this inter-annual variation.
Love your Mother Earth: As carbon emissions climb, so too has the Earth's capacity to remove CO2 from the atmosphere — Last modified June 08, 2015 16:12
A new paper, co-authored by Woods Hole Research Center Senior Scientist Richard A. Houghton, entitled, "Audit of the global carbon budget: estimate errors and their impact on uptake uncertainty", was published in the journal Biogeosciences.
Simulating seasons — Last modified June 03, 2015 11:15
UT Austin researchers use supercomputing to assess the impact of climate change on the country's growing season.
Earlier flowering could offset heat stress in winter wheat — Last modified June 03, 2015 11:14
Climate change looks set to increase heat stress on crops and reduce yields for crops such as winter wheat. But winter wheat now flowers two weeks earlier than it did in the 1970s. And researchers in Germany have found that this change in phenology almost compensates for the increasing frequency and magnitude of heat stress.
2°C climate change target 'utterly inadequate' — Last modified May 29, 2015 09:56
The official global target of a 2°C temperature rise is 'utterly inadequate' for protecting those at most risk from climate change, says a lead author on the Intergovernmental Panel on Climate Change (IPCC), writing a commentary in the open access journal Climate Change Responses.
Good luck reverses global forest loss — Last modified May 29, 2015 09:52
Analysis of 20 years of satellite data has revealed the total amount of vegetation globally has increased by almost the equivalent of 4 billion tonnes of carbon since 2003. This is despite ongoing large-scale deforestation in the tropics.
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.
