#idw Study: “Hidden” #contrails in #cirrus clouds contribute to #climatewarming

Researchers at the Institute for #Meteorology at Leipzig University have, for the first time, determined the climatic impact of contrails that form within natural cirrus clouds. Contrails account for the largest share of aviation’s climate impact beyond carbon dioxide emissions. https://idw-online.de/en/news863338

Study: “Hidden” contrails in cirrus clouds contribute to climate warming

#UN #climate talks are getting weird. One of the most consequential rounds of global climate negotiations has kicked off in Belém, Brazil. Leaders from nearly every country in the world - but notably, not the US - are gathering (...)

UN climate talks are getting weird

World leaders will try to make progress on climate change at UN negotiations despite uncertainties driven in part by Trump, rising energy demands, and AI.

"Forecasting #bryozoan assemblage dynamics under simulated #ClimateChange" by Mira Baer et al.

We use an #IndividualBasedModel to explore potential future bryozoan assemblage dynamics. We show that successional patterns strongly depend on the duration of the growing season as well as on the spatial distribution of predation events - which are both likely to change due to #ClimateWarming...

Chao Wang et al. investigated the effects of simulated nighttime warming and atmospheric #NitrogenDeposition on the temperatures of shallow water, deep water, and sediment, and also explored the potential influence of #Microclimate on wetland carbon cycles.

From the original article in The Age in 2021:

Should Australia warm by 3 degrees, the number of days hotter than 35 degrees in Sydney would jump from an average of 3.1 to 11 each year, while in Melbourne the jump would be from 11 to 24. In Darwin, the average number of days hotter than 35 degrees would go from 11 to 265 — every day would be designated a heat stress day.

Altered Water Cycles:
Changes in vegetation can affect local precipitation patterns, impacting agriculture and natural water sources.

Increased Carbon Release:
Deforestation and degradation can release stored carbon, further exacerbating climate change.

That was the output on the assumption of 3 degrees warming.

We are on track of 3.1C warming.

5/
Changes in Ecosystems:
Coral reefs may face extensive bleaching, negatively affecting marine biodiversity and fishing communities.

Reduced Recreational Spaces:
As beaches erode and water quality declines, recreational water activities may diminish, impacting local businesses.

Ecosystem Changes: From Jungle to Savannah

Biodiversity Loss:
Tropical forests may be replaced by savannah ecosystems, resulting in the loss of species diversity.

Greater incidence of vector-borne diseases as habitat extends for carriers such as mosquitoes.

Economic Consequences:
Rising costs for cooling, healthcare, and disaster recovery impacting local economies.

Specific Impacts on Beaches

Beach Erosion and Loss:
Many beaches will disappear due to sea level rise, leading to economic loss in tourism sectors.

Specific Impacts on Cities

Infrastructure Stress:
Heat-related Failures: Transportation systems and energy grids may struggle due to higher temperatures.

Water Supply Risk: Reduced freshwater availability due to changes in precipitation patterns.

Public Health Risks:
Increased respiratory and cardiovascular conditions from heat and air quality deterioration.

Increased Heatwaves: Urban areas, often referred to as "heat islands," will experience intensified heat, causing health issues and increased energy demands.

Sea Level Rise: Coastal cities may face significant flooding due to melting ice caps and glaciers, as well as thermal expansion of seawater.

Extreme Weather: Increased frequency of storms, hurricanes, and heavy rainfall can lead to infrastructure damage in cities and coastal areas.
