There Is No Climate Slowdown: Earth’s Oceans Are Heating Up Faster Than Previously Reported
The ocean is heating up faster than previously thought, according to new research out this week, and that might help explain the recent spate of historic hurricanes and decline in a number of marine species.

Climate Change Is Already Helping To Drive Up Homelessness
We already can reasonably expect that climate change will increase gentrification in the future, as people with money who get pushed by rising seas on the coasts seek replacement housing further inland.
But climate change is already causing housing problems. It helps increase homelessness.

A Wyoming Reservation Shows the New Face of Drought
A climate-driven warping of the water cycle is forcing a re-think of water management practices
The traditional measure of drought has been an absence of rainfall. Much later, [Mike] Hobbins stumbled across a way to measure the early stages of droughts by calculating what he calls the “evaporative demand,” or the “growing thirst of the atmosphere.” He found a set of weather data, spanning 38 years, giving him the basic creators of dryness: the wind, air temperature, humidity and incoming solar radiation. That allowed him to identify developing droughts on weather maps without needing to know local soil moisture conditions.

Trump White House quietly cancels NASA research verifying greenhouse gas cuts
You can’t manage what you don’t measure. The adage is especially relevant for climate-warming greenhouse gases, which are crucial to manage—and challenging to measure. In recent years, though, satellite and aircraft instruments have begun monitoring carbon dioxide and methane remotely, and NASA’s Carbon Monitoring System (CMS), a $10-million-a-year research line, has helped stitch together observations of sources and sinks into high-resolution models of the planet’s flows of carbon. Now, President Donald Trump’s administration has quietly killed the CMS, Science has learned.

Freshwater feedback loops accelerating Antarctic glacial melt
In a study released April 18 in the journal, Science Advances, “Freshening by glacial meltwater enhances melting of ice shelves and reduces formation of Antarctic Bottom Water,” climate scientists Alessandro Silvano et al. reveal that the melting of Antarctic glaciers is creating a feedback loop that is driving ice loss faster, much faster, than originally thought possible.
Our results suggest that increased glacial meltwater input in a warming climate will both reduce Antarctic Bottom Water formation and trigger increased mass loss from the Antarctic Ice Sheet, with consequences for the global overturning circulation and sea level rise.
A good summation of the issue can be found at Common Dreams. In 2016, former NASA climate scientist James Hansen, on the potential for such feedback loops, noted “These feedbacks raise questions about how soon we will pass points of no return in which we lock in consequences that cannot be reversed on any time scale that people care about. Consequences include sea level rise of several meters, which we estimate could occur this century or at latest next century if fossil fuel emissions continue at a high level. That would mean loss of all coastal cities, most of the world’s large cities and all their history.”
