Climate change, causes and impacts

Unseasonal rain damages cash crops in Maharashtra — Última modificación 07/01/2015 09:50

Climate change could cut West African sorghum yields by a fifth — Última modificación 04/12/2014 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 — Última modificación 04/12/2014 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 — Última modificación 04/12/2014 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.

Climate change impacts countered by stricter fisheries management — Última modificación 08/11/2014 16:53
A new study has found that implementing stricter fisheries management overcame the expected detrimental effects of climate change disturbances in coral reef fisheries badly impacted by the 1997/98 El Niño, according to the Wildlife Conservation Society.
IPCC releases Synthesis Report for fifth assessment — Última modificación 08/11/2014 16:51
The Intergovernmental Panel on Climate Change (IPCC) has released the Synthesis Report for its fifth assessment. The document brings together the findings of the three reports issued during the last 13 months.
Scientists put upper limit on sea-level ris — Última modificación 03/11/2014 16:38
This year’s IPCC fifth assessment report put the “likely” – or 66% probability – sea-level rise by 2100 at between 0.29 and 0.98 m. But there is a one in three chance that sea-level rise could be higher than this. Now researchers have examined this upper limit and found there is a 95% chance that sea-level rise this century will be no more than 1.8 m.

Weather History Time Machine — Última modificación 24/10/2014 12:30
During the 1930s, North America endured the Dust Bowl, a prolonged era of dryness that withered crops and dramatically altered where the population settled. Land-based precipitation records from the years leading up to the Dust Bowl are consistent with the telltale drying-out period associated with a persistent dry weather pattern, but they can’t explain why the drought was so pronounced and long-lasting.
Century of northeast Pacific warming due to changing winds — Última modificación 13/10/2014 10:16
Much of the sea-surface warming seen around the western coasts of North America since 1900 is due to changes in wind patterns, according to scientists from the US. The team used independent records of sea-surface temperature (SST), surface air temperature and sea-level pressure, an indicator of large-scale wind conditions, to carry out the analysis.
Climate change and storm tracks: a tale of two hemispheres — Última modificación 01/10/2014 09:36
Last winter the UK saw exceptional rainfall and flooding, with the wettest December to January period since 1910 and parts of southern England receiving more than 200% of their average monthly rainfall. According to the UK Met Office, the clustering and persistence of the storms that swept in from the Atlantic was highly unusual, carried in on an exceptionally fast and strong jet stream. So is this the kind of winter the UK should come to expect? A new study in Environmental Research Letters (ERL) tries to glimpse the storms of the future.
Global warming slowdown answer lies in depths of Atlantic, study finds — Última modificación 29/09/2014 10:31
Excess heat being stored hundreds of metres down in Atlantic and Southern oceans – not Pacific as previously thought

Extreme weather becoming more common, study says — Última modificación 29/09/2014 10:15
Extreme weather like the drought currently scorching the western US and the devastating floods in Pakistan in 2010 is becoming much more common, according to new scientific research.
Future crop production threatened by extreme heat — Última modificación 29/09/2014 10:14
Uncertainties in the occurrence of heat stress under field conditions, plant responses to heat, and appropriate adaptation measures still need further investigation, say Stefan Siebert and Frank Ewert.

Stanford study shows effects of biomass burning on climate, health — Última modificación 17/08/2014 16:23
Biomass burning – whether accidental wildfires or deliberate burning of forests to create agricultural lands – has long been known to affect both climate change and public health.
The interaction of climate change, fire, and forests in the U.S. — Última modificación 17/08/2014 16:22
A special section of the September issue of Forest Ecology and Management, available online now, assesses the interactions among fire, climate change, and forests for five major regions of the United States.
Water vapour rise is due to man — Última modificación 17/08/2014 16:20
Man-made greenhouse gases have increased the amount of water vapour in the upper troposphere, a team from the US has confirmed. The phenomenon could further amplify the effects of climate change, since water vapour also acts as a greenhouse gas.
