Urban climate change

ScienceDaily - 11. September 2017 - 22:09
Southern cities such as Houston and Tampa -- which faced the wrath of hurricanes Harvey and Irma, respectively -- may not be the only urban environments vulnerable to extreme weather. Northern cities also face the potential for flooding as global temperatures continue to warm.

How openings in Antarctic sea ice affect worldwide climate

ScienceDaily - 11. September 2017 - 19:26
In a new analysis of climate models, researchers reveal the significant global effects that seemingly anomalous polynyas, or openings in sea ice, can have. Their findings indicate that heat escaping from the ocean through these openings impacts sea and atmospheric temperatures and wind patterns around the globe and even rainfall around the tropics.

Extreme weather has limited effect on attitudes toward climate policies

ScienceDaily - 7. September 2017 - 21:46
People who recently experienced severe weather events such as floods, storms and drought are more likely to support policies to adapt to the effects of climate change, according to a new study.

Warmer world may bring more local, less global, temperature variability

ScienceDaily - 5. September 2017 - 19:32
Many tropical or subtropical regions could see increases in naturally occurring temperature variability as Earth warms over coming decades, a new study suggests. These local changes could occur even though Earth's global mean surface temperature variability will likely decrease because of less solar reflection from icecaps at high latitudes.

Record-low 2016 Antarctic sea ice due to 'perfect storm' of tropical, polar conditions

ScienceDaily - 31. August 2017 - 16:26
The sudden, unexpected nosedive in Antarctic sea ice last year was due to a unique one-two punch from atmospheric conditions both in the tropical Pacific Ocean and around the South Pole.

Research in ancient forests show link between climate change and wildfires

ScienceDaily - 29. August 2017 - 16:10
Researchers studying centuries-old trees in South America have found a tight correlation between wildfires and a warm weather fluctuation that has become more frequent in recent decades -- and will continue to be more frequent as the climate warms.

Genetic map reveals heat tolerance traits in peas

ScienceDaily - 23. August 2017 - 16:10
As the global climate changes and temperatures continue to rise, heat stress is becoming a major limiting factor for pea cultivation. A new study indicates that pea plants with some specific traits -- such as longer flowering time and higher pod numbers -- may be more resistant to heat stress. The researchers also gained new insights into the genetics of heat tolerance in pea.

Wood frogs research clarifies risks posed to animals by warming climate

ScienceDaily - 19. August 2017 - 17:37
As conditions warm, fish and wildlife living at the southern edge of their species' ranges are most at risk, according to researchers who led a major collaborative study of how wood frogs are being affected by climate change.

Spoiler alert: Computer simulations provide preview of upcoming eclipse

ScienceDaily - 18. August 2017 - 16:21
Scientists have forecast the corona of the sun during the upcoming eclipse. The findings shed light on what the eclipse of the sun might look like Aug. 21 when it will be visible across much of the US, tracing a 70-mile-wide band across 14 states.

Urban floods intensifying, countryside drying up

ScienceDaily - 14. August 2017 - 16:29
Drier soils and reduced water flow in rural areas -- but more intense rainfall that overwhelms infrastructure and causes flooding and stormwater overflow in urban centers. That's the finding of an exhaustive study of the world's river systems, based on data collected from more than 43,000 rainfall stations and 5,300 river monitoring sites across 160 countries.

Human-caused warming likely led to recent streak of record-breaking temperatures

It is 'extremely unlikely' 2014, 2015 and 2016 would have been the warmest consecutive years on record without the influence of human-caused climate change, according to the authors of a new study.

Intense rainfall in the Alps of NW Italy, SE France and S Switzerland – August 8, 2017

Severe Weather Europe - 8. August 2017 - 11:31
Intense rainfall is expected over the western Alps in northwestern Italy, southeastern France and southern Switzerland today. Rainfall totals will locally exceed 100 mm / 24h. There will be a significant risk for locally intense flash flooding. A very strong mid-level southwesterly jetstream is present ahead of the advancing trough, currently located over France. Strong upslope flow, orographic lift and synoptic scale lift over the left exit region of the jetstreak will provide a favourable environment for formation of training cells. Various high-resolution models indicate widespread totals of 40-100 mm / 24h, while locally totals may exceed 150 mm / 24 h. Expect enhanced threat of (locally intense) flash flooding. In addition, these thunderstorms will also pose a threat for

By the end of the century extreme weather events may affect two in three Europeans every year

ScienceDaily - 7. August 2017 - 4:27
By 2100, two in three people living in Europe may be affected by weather-related disasters, according to a new study which sheds light on the expected burden of climate change on societies across Europe. The projected increases were calculated on the assumption of there being no reduction in greenhouse gas emissions and no improvements to policies helping to reduce the impact of extreme weather events (such as medical technology, air conditioning, and thermal insulation in houses).

Adriatic sea temperature peaking: 28-30 °C

Severe Weather Europe - 6. August 2017 - 6:58
The temperature of the Adriatic sea is peaking today, ahead of the Tramontana and Bora/Bura winds expected late today and tomorrow. Much of the sea is now at 28-30 °C. In particular, the warmest areas are in the northern Adriatic, around the Venice lagoon and the coasts of Emilia Romagna, Veneto, Friuli, the Slovenian coast and northern Istra (Croatia). Sea surface temperature in the Adriatic sea forecast for Sunday, August 6. Map: Adriatic Forecasting System. Sea surface temperature anomaly in the Adriatic sea forecast for Sunday, August 6. Map: Adriatic Forecasting System. Slightly less warm waters, with temperatures mostly between 26 and 28 °C are present in the Kvarner region in Croatia and in the southern Adriatic along the coast

Severe Tramontana winds over the northern Adriatic region later today – August 6, 2017

Severe Weather Europe - 6. August 2017 - 6:01
Severe Tramontana winds are expected later today across the northern Adriatic region with the cold front passage. Most models agree on a strong push of Tramontana winds across the Friuli and Veneto plains in Italy into the northern Adriatic. Peak wind gusts may reach 100-135 km/h! There is significant damage potential with this event. Affected areas will also include the eastern coast of the Adriatic in Italy (Trieste gulf), Slovenia and Croatia (Istra) and the western coast of the Adriatic (eastern Emilia Romagna). The timing of the event will be in the late afternoon. All holidaymakers in the northern Adriatic need to be aware of this event, as the Tramontana wind will have significant damage potential – precautions to avoid

Extremely warm Adriatic sea – an update

Severe Weather Europe - 4. August 2017 - 23:32
The Adriatic sea has further warmed over the past several days under the extreme heat wave that is affecting the entire N-CNTRL Mediterranean region. 7-day sea surface temperature average over the northern Adriatic: very high temperatures in the 28-30 °C range over the past week. Note the 30+ °C average in the Venice Lagoon, along the coast of eastern Veneto and around the Po delta. Note, however, that temperatures have also peaked at 29-30 °C in the NE corner (Gulf of Trieste) over the past few days! Map: Consorzio LaMMA. Zarja buoy data (Gulf of Trieste): water temperature at 2 m depth (!) reached 29.5 °C today (August 4). Data: Slovenian Environmental Agency (ARSO). Temperatures along the northern coast (Friuli,
