The Arctic is one of the fastest-warming places on the planet —and scientists still aren’t completely sure why. This is an emerging area of research, with the exact magnitude of the effects still unclear. As a result, the effect is not well-represented —if at all —in most climate models. “There’s a chance that some model projections could be underestimating future climate change, particularly in the Arctic. More research may clarify whether that’s actually the case and exactly how much plants are contributing to the warming that’s happening all over the globe,” stated Jin-Soo Kim.

“In many ways, what we’re seeing now is a rapid and unplanned version of economic ‘degrowth’ – the transition some academics and activists have for decades said is necessary to address climate change, and leave a habitable planet for future generations. Degrowth is a proposed slowing of growth in sectors that damage the environment, such as fossil fuel industries, until the economy operates within Earth’s limits,” stated Dr. Natasha Chassagne.

‘For the Dutch, consulting with cities about their response to relative sea-level rise has become a growth industry. They’re the Silicon Valley of water management, a laboratory testing strategies that have evolved over the centuries. No wonder. Water has been both a daily threat and a national identity for a country about the size of Maryland. More than half the nation’s 17 million people live on land below sea level,” wrote Jim Morrison. “Rising seas threaten 10 percent of the world’s urban population so there’s never-ending demand.”

“Despite being invisible to the naked eye, black carbon particles affect the ability of the snow to reflect incoming sunlight, a phenomenon known as “albedo”. Similar to how a dark-coloured car will heat up more quickly in direct sunlight when compared with a light-coloured one, glaciers covered by black carbon particles will absorb more heat, and thus melt faster,” stated Matthew Harris. “With communities reliant on glaciers for water, work examining complex forces like black carbon is needed more now than ever before.”

“What is striking about the last interglacial record is how high and quickly sea level rose above present levels. Temperatures during the last interglacial were similar to those projected for the near future, which means melting polar ice sheets will likely affect future sea levels far more dramatically than anticipated to date,” stated Fiona Hibbert. “This means that if climate change continues unabated, Earth’s past dramatic sea level rise could be a small taste of what’s to come.”

Large fires have happened before. But this latest extraordinary situation raises many questions. It is as if many of the major fires in the past are now being rerun concurrently. What is unprecedented is the size and number of fires rather than the seasonal timing. Typically wet parts of the landscape have literally evaporated, allowing fire to spread unimpeded. It is no coincidence current fires correspond directly with hotspots of record low rainfall and above-average temperatures.

“The word ‘upended’ does not do justice to the revolution in climate science wrought by the discovery of sudden climate change. The realization that the global climate can swing between warm and cold periods in a matter of decades or even less came as a profound shock to scientists who thought those shifts took hundreds if not thousands of years,” wrote Eugene Linden. “Even if scientists end up having lowballed their latest assessments….climate change is already here. And it is going to get worse. A lot worse.”

The Crowther Lab at ETH Zurich investigates nature-based solutions to climate change. In their latest study the researchers showed for the first time where in the world new trees could grow and how much carbon they would store. Dr. Jean-Francois Bastin, also suggests that there is further potential to regrow trees in croplands and urban areas, highlighting the scope for agroforestry and city trees to play a significant role in tackling climate change.

“Empathy evolved as one of humans’ vital survival skills. It is only through our foray into the modern world that we have lost touch with our evolutionary empathy. Deeply empathic people tend to be environmentally responsible, but our caring instincts are short-sighted and dissolve across space and time, making it harder for us to deal with things that haven’t happened yet. Touching the past can connect us to the future, especially when we look back fondly,” wrote Jamil Zaki.

“If we’re going to see more heavy rainfall events and we’re going to see them especially in areas that are not designed for those floods, that means that we need to think about how to adapt our infrastructure and rethink the way we’ve designed some of our bridges and drainage systems,” said Christa Peters-Lidard, Deputy Director for Hydrology, Biospheres, and Geophysics at NASA’s Goddard Space Flight Center, Maryland. But while some areas are projected to get wetter, others will become much drier. Warming temperatures and changing precipitation patterns can lead to droughts.
