Global Weather Patterns and Coastlines

Coasts are sensitive to sea level rise, changes in the frequency and intensity of storms, increases in precipitation, and warmer ocean temperatures. In addition, rising atmospheric concentrations of carbon dioxide (CO2) are causing the oceans to absorb more of the gas and become more acidic. This rising acidity can have significant impacts on coastal and marine ecosystems.

The impacts of climate change are likely to worsen problems that coastal areas already face. Confronting existing challenges that affect man-made infrastructure and coastal ecosystems, such as shoreline erosion, coastal flooding, and water pollution, is already a concern in many areas. Addressing the additional stress of climate change may require new approaches to managing land, water, waste, and ecosystems…

Rivers in the Sky

Atmospheric rivers are relatively long, narrow regions in the atmosphere – like rivers in the sky – that transport most of the water vapor outside of the tropics. These columns of vapor move with the weather, carrying an amount of water vapor roughly equivalent to the average flow of water at the mouth of the Mississippi River. When the atmospheric rivers make landfall, they often release this water vapor in the form of rain or snow…

Coastal erosion and landfill exposure: Future impacts of climate change – Legal Futures

The UK’s historic coastline is a ticking pollution time bomb that is being rapidly accelerated by the impacts of climate change and landfill exposure…

As an island nation the UK has the largest coastline in Europe of 17,381km and is surrounded by four water bodies (Atlantic ocean, North Sea, Irish Sea and English Channel). For this reason, 28% of the UK’s coastline is vulnerable to coastal erosion as climate change has accelerated rising sea levels and increasingly hazardous weather…

California cleans up from one storm as it prepares for another – CNN

Days after California was hit by “the most impressive storm in nearly 20 years,” the state – fully saturated in many places – is gearing up this weekend for yet another series of atmospheric river events, with flooding, hail, powerful wind gusts and even funnel clouds possible in spots…
