The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. The Sea Level Rise Technical Report provides the most up-to-date sea level rise projections for all U.S. states and territories by decade for the next 100 years and beyond, based on a combination of tide gauge and satellite observations and all the model ensembles from the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

“Thwaites glacier, the widest in the world at 80 miles wide, is held back by a floating platform of ice called an ice shelf, which makes it flow less quickly. But scientists have just confirmed that this ice shelf is becoming rapidly destabilised. The eastern ice shelf now has cracks criss-crossing its surface, and could collapse within ten years. If Thwaites’ ice shelf did collapse, it would spell the beginning of the end for the glacier. Without its ice shelf, Thwaites glacier would discharge all its ice into the ocean over the following decades to centuries.” stated Dr. Ella Gilbert.

“A new study provides a glimpse into the future of Western U.S. snow and the picture is far from rosy. Due to rising temperatures, the region has already lost 20 percent of its snowpack since the 1950s. That’s enough water to fill Lake Mead, the nation’s largest human-made reservoir. It stands to lose another half, and possibly more, later this century, from the Rockies to the Sierra Nevada and into the Cascades of the Pacific Northwest, according to a literature synthesis conducted in the study leveraging dozens of peer-reviewed climate model projections,” stated Diana Leonard.

“In the last few years I have also worked on the environmental benefits of trees in urban areas, and their role in climate-proofing our cities. We have been investigating how the cooling, shading and flood-prevention benefits they provide are affected by the species of tree and the growing conditions. All this will help us appreciate the importance of man’s long relationship with trees and with the wood they produce,” stated Roland Ennos. “To determine whether the humble tree really can provide such robust defences, we first need to understand the role they play in soaking up excess rain water,”

“Singapore is one of most densely populated countries in the world. It faces the twin challenges of ensuring sustainable water supply during droughts as well as effective drainage during intense rain seasons amid climate change. For over two decades, Singapore’s National Water Agency, PUB, has successfully added large-scale nationwide rainwater harvesting, used water collection, treatment and reuse, and seawater desalination to its portfolio of conventional water sources, so the nation-state can achieve long-term water sustainability,” stated Peter Joo Hee Ng.

According to Marty Ralph, despite being relatively small compared to the rest of the atmosphere, these rivers in the sky can carry up to 95 per cent of the water vapour that travels around the Earth’s surface, and can bring anywhere between 30 and 50 per cent of a given region’s yearly water supply.The warmer the air is, the more water vapour it can carry. As the atmosphere’s average temperature rises, then, an atmospheric river can grow — and when it makes landfall, it can release more rain or snow than in years past.

A sponge city is a new urban construction model for flood management, strengthening ecological infrastructure and drainage systems, proposed by Chinese researchers in 2014. “Extreme weather, a changing climate, and impervious streets and roads have combined to create an urban disaster. All of this has seen cities begin to re-imagine their relationship with water. Rather than just designing systems that allow the water to drain away slowly and stably, they want to harvest and reuse it,” stated Laurie Winkless.

“In our highly connected world, climate risks and our responses to them can be transmitted from one system or sector to another, creating new risks and making existing ones more or less severe. In many cases risks cannot be understood without considering these interactions. Recent evidence indicates how some of the most severe climate change impacts, such as those from deadly heat or sudden ecosystem collapse, are strongly influenced by interactions across sectors and regions,” stated Nicholas Simpson.

“Mother Nature has had it with her brood. If you can’t see that, you haven’t been paying attention. The defining struggle of our time, and our future, will be the tension between Mother Nature and human nature. So, more of us need to think differently about who and what we are dealing with here. That seems to have finally begun. In a season of catastrophic, deadly and too-common extreme weather events, there are signs that even people who were hesitant to embrace the science behind climate change are waking up to the threat,” stated Michele Norris.

“I have re-evaluated how I discuss my own research. I was taking some of the terminology for granted as it is repeated in the literature time and time again but words like ‘stormwater’, ‘rainwater’ and ‘drainage’ can have such powerful unconscious effects on how you interpret the discussions and they can mean different things to different stakeholders in the system. These terminology choices ultimately have a large effect in science communication and the message you intend to convey,” stated Charles Axelsson.
