Video: Kiribati - A Climate Change Reality

Boobu Tioram, a resident of the Pacific island of Kirabati, took time out from reinforcing a seawall in front of his newly built house to speak with UNDP about what climate change has meant to his way of life. 

Study: Sea level rise causes Texas coastal homeowners to lose millions in potential property value: Houston Chronicle

"Sea level rise has cost Texas homeowners $76.4 million in potential property value, with Galveston hit the hardest, a new study released Tuesday found.

First Street Foundation and Columbia University analysts examined about 3 million coastal properties in Texas. Using a combination of real estate transactions and tidal flooding exposure, they found that from 2005 to 2017, homes in Galveston lost $9.1 million in potential value, followed by Jamaica Beach (which lost $8.6. million) and the Bolivar Peninsula ($8.1 million). It’s not necessarily that these coastal homes decreased in value by these amounts, the authors say, but that they didn’t appreciate as much as similar homes not exposed to tidal flooding. Researchers factored in square footage, proximity to amenities and economic trends like the 2008 housing recession."

The Bank of England lays bare the “very real” trillion-dollar risks of climate change: QUARTZ

My message today is simple. Climate change poses significant risks to the economy and to the financial system, and while these risks may seem abstract and far away, they are in fact very real, fast approaching, and in need of action today.

That’s how Sarah Breeden began her speech titled “Avoiding the storm: Climate change and the financial system” (pdf) yesterday. Breeden is the Bank of England’s executive director of International Banks Supervision and she was speaking at the Official Monetary & Financial Institutions Forum in London.

The urgency in Breeden’s speech was also on display on London’s streets. Earlier in the day, the environmental group Extinction Rebellion blocked traffic in five iconic locations across the city in a peaceful, non-violent protest to bring attention to “inactivity” of governments on fighting climate change.

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns: PHYSORG

A "sleeping giant" hidden in permafrost soils in Canada and other northern regions worldwide will have important consequences for global warming, says a new report led by University of Guelph scientist Merritt Turetsky. 

Scientists have long studied how gradual permafrost thaw occurring over decades in centimetres of surface soils will influence carbon release to the atmosphere. But Turetsky and an international team of researchers are looking at something very different: rapid collapse of permafrost that can transform the landscape in mere months through subsidence, flooding and landslides.


"We are watching this sleeping giant wake up right in front of our eyes," said Turetsky, who holds the Canada Research Chair in Integrative Ecology.

Alaska's in The Middle of a Record-Breaking Spring Melt, And It's Killing People: WP

From Science Alert

Bryan Thomas doesn't want any more "wishy-washy conversations about climate change." For four years, he has served as station chief of the Barrow Atmospheric Baseline Observatory, America's northernmost scientific outpost in its fastest-warming state.

Each morning, after digging through snow to his office's front door, Thomas checks the preliminary number on the observatory's carbon dioxide monitor. On a recent Thursday it was almost 420 parts per million - nearly twice as high as the global preindustrial average.

It's just one number, he said. But there's no question in his mind about what it means.

Alaska is in the midst of one of the warmest springs the state has ever experienced - a transformation that has disrupted livelihoods and cost lives.

Large potential reduction in economic damages under UN mitigation targets: Nature IJS

"International climate change agreements typically specify global warming thresholds as policy targets¹, but the relative economic benefits of achieving these temperature targets remain poorly understood^2,3. 

Uncertainties include the spatial pattern of temperature change, how global and regional economic output will respond to these changes in temperature, and the willingness of societies to trade present for future consumption. 

Here we combine historical evidence⁴ with national-level climate⁵ and socioeconomic⁶ projections to quantify the economic damages associated with the United Nations (UN) targets of 1.5 °C and 2 °C global warming, and those associated with current UN national-level mitigation commitments (which together approach 3 °C warming⁷)."
