Good morning from Tanzania! Here to look at Kukua's weather station project, helping smallholder farmers to manage climate change. *****Military adaptation: Norfolk/Hampton Roads naval base - our largest - is raising docks ~6 feet because #climate change is raising sea levels. No denial there. Cutting emissions isn't enough, we need to start removing carbon from the atmosphere. #CarbonPrice in #Australia increased #renewables reduced #emissions drove up price. That's what it was designed for. Negative Emissions Key to Meeting 2°C Threshold. Humans will have to not only stop emitting greenhouse gases by 2085, but also develop technology that will result in negative emissions — the removal of 15 billion tons of carbon dioxide from the atmosphere each year by the end of the century — in order to prevent global warming from exceeding 2°C (3.6°F), according to a new study.
Human greenhouse gas emissions, including methane and carbon dioxide, have already warmed the globe more than 1°C (1.8°F) compared to pre-industrial levels. Negative emissions tech: can more trees, carbon capture or biochar solve our CO2 problem? In the 2015 Paris climate agreement, 195 nations committed to limit global warming to two degrees above pre-industrial levels.
But some, like Eelco Rohling, professor of ocean and climate change at the Australian National University’s research school of earth sciences, now argue that this target cannot be achieved unless ways to remove huge amounts of carbon dioxide from the atmosphere are found, and emissions are slashed. This is where negative emissions technologies come in. Climate stabilization: Planting trees cannot replace cutting carbon dioxide emissions. Growing plants and then storing the CO2 they have taken up from the atmosphere is no viable option to counteract unmitigated emissions from fossil fuel burning, a new study shows.
The plantations would need to be so large, they would eliminate most natural ecosystems or reduce food production if implemented as a late-regret option in the case of substantial failure to reduce emissions. However, growing biomass soon in well-selected places with increased irrigation or fertilization could support climate policies of rapid and strong emission cuts to achieve climate stabilization below 2 degrees Celsius. Three scenarios: Business as usual, Paris pledges, or ambitious CO2 reductions. *****Assessing threat from sea level rise: UNEP app helps coastal communities adapt to climate change - Daily Planet. The United Nations Environment Programmme(UNEP) has launched a web app and infographic to support people living and working on coasts in making decisions on how to adapt to a changing climate.
Rising populations and climate change are increasing sea level, storm intensity and rainfall. The Coastal Hazard Wheel can be used to consider how different coastlines should respond. The web app opens up access to scientific background material and coastal classification data, in order to aid decision-making and standardise its communication worldwide.
An infographic assists in areas with less data by helping users classify their location using things like local geology, tides and hazards like flooding and erosion. It gives 24 different options for coastal management, including wetland restoration and cliff stabilisation. *****Adaptation to or mitigation of climate change?: Cats in the shade. *****Cost of climate change / risk register: Leading insurers tell G20 to stop funding fossil fuels by 2020. Three of the world’s biggest insurers have called on G20 leaders to implement a timeframe for ending fossil fuel subsidies when they meet in China this week.
*****Climate change mitigation: UK launches ‘world first’ research programme into negative emissions. The public money will fund projects exploring the real-world potential of “negative emissions” technologies (NETs), including soil carbon management, afforestation, bioenergy with carbon capture and storage (BECCS), enhanced weathering and direct capture of methane from the air.
NETs will “almost certainly be needed” to reach the goals of the Paris Agreement on climate change, one of the researchers tells Carbon Brief. Yet there is huge uncertainty over whether it will be possible to deploy them quickly – and at scale – without causing knock-on environmental and social problems. The new research programme is designed to investigate their potential, as well as the political, social and environmental issues surrounding their deployment.

Could small islands threatened by sea level rise find a new future afloat?
By Sebastien Malo NEW YORK, March 20 (Thomson Reuters Foundation) - When former Google software engineer Patri Friedman came up with the idea of building floating islands, he had in mind an unusual buyer: Libertarians, seeking freedom to live beyond the reach of governments. But his futuristic plan has now found a new, motivated and very different audience - small islands halfway around the world that are slowly being submerged by sea level rise. Benefits far outweigh costs of tackling climate change - say economists. Atlantic City and Miami Beach: two takes on tackling the rising waters. The Irish Pub near Atlantic City’s famed boardwalk doesn’t have any locks on the doors as it is open 24 hours a day.
So when Hurricane Sandy crunched into what was once known as the Las Vegas of the east coast in 2012, some improvisation was needed. Regular drinkers helped slot a cork board through the frame of the door, wedging it shut and keeping out the surging seawater. The wild night, which severely damaged more than 320 homes and caused a week-long power blackout, was seen out by those taking shelter with the help of several bottles of Jameson. But Sandy was just the headline act among increasingly common flooding events that are gnawing away at the thin island upon which the city sits.
“Sandy, as devastating as it was, isn’t the greatest barometer because we have flash floods,” said Cathy Burke, who has run the Irish Pub since 1973. “We can have floods at the drop of a hat,” Burke said. *****Future - Miami’s fight against rising seas (climate change adaptation) The first time my father’s basement flooded, it was shortly after he moved in.
The building was an ocean-front high-rise in a small city north of Miami called Sunny Isles Beach. *****Climate mitigation: Don't upgrade, update.

US scientists are set to send aerosol injections 20km up into the earth’s stratosphere in the world’s biggest solar geoengineering programme to date, to study the potential of a future tech-fix for global warming.
The $20m (£16m) Harvard University project will launch within weeks and aims to establish whether the technology can safely simulate the atmospheric cooling effects of a volcanic eruption, if a last ditch bid to halt climate change is one day needed. Scientists hope to complete two small-scale dispersals of first water and then calcium carbonate particles by 2022. Future tests could involve seeding the sky with aluminium oxide – or even diamonds.

Ireland passes law to become world's first country to fully divest from fossil fuels. Ireland has voted to be the world’s first country to fully divest public money from fossil fuels. The Irish Parliament passed the historic legislation in a 90 to 53 vote in favour of dropping coal, oil and gas investments from the €8bn (£6.8bn) Ireland Strategic Investment Fund, part of the Republic’s National Treasury Management Agency.
The Factory as Forest – The Dirt. “Our goal is to achieve zero negative environmental impacts by 2020,” said Erin Meezan, vice president at Interface, an innovative producer of carpets and textiles, at Greenbuild in Los Angeles. But as the firm nears its goal, it’s now pursuing an even more ambitious vision — the “factory as forest,” in which their manufacturing facilities become positive contributors to the environment, providing as much ecosystem service benefits as their surrounding landscape. This astonishing vision comes from Interface’s deceased founder Ray Anderson and Janine Benyus, whose firm, Biomimicry 3.8, is advising them. Benyus’ guiding idea: “When the forest and the city are functionally indistinguishable, then we know we’ve embedded sustainability.” To achieve this, she calls for using biomimetic design strategies that “consciously emulate nature’s designs.”

After the climate talks in Marrakech, our climate mission remains the same as what was set out in the 2015 Paris Agreeement: to eliminate all carbon dioxide emissions by the middle of this century. While the long-term focus is on 2050 or 2100, what matters now is the next ten years. If we miss bending the rising emissions curve downward by around 2020, we may well miss the chance to avoid the worst climate damage. We looked at all the major emitting sectors and the most recent scientific analyses of what can be done – and how fast – to come up with a list of the most important things to do in the next five to ten years to bend the emissions curve downwards.
Here’s the good news: for all areas, we show signs that a transition of this magnitude is possible. In many cases, it’s already happening. ***Scientists are building a system that could turn atmospheric CO2 into fuel. Scientists in Canada are developing an industrial carbon dioxide recycling plant that could one day suck CO2 out of the atmosphere and convert it into a zero-carbon e-diesel fuel. Developed by tech start-up Carbon Engineering and partly funded by Bill Gates, the system will essentially do the job of trees, but in places unable to host them, such as icy plains and deserts.

Our newest Climate Action Tracker report spells out important, short-term steps over the next ten years that key sectors need to take to help the world achieve the Paris Agreement’s 1.5°C limit.
All key sectors – energy generation, road transport, buildings, industry, forestry and land use, and commercial agriculture – have to begin major efforts to cut emissions by, latest, 2020. By 2025 they should have accelerated these efforts in order to reach a globally aggregated zero carbon dioxide emissions by mid-century. Plants appear to be trying to rescue us from climate change. For decades, we’ve been pumping billions of tons of harmful greenhouse gases into the air, and for decades plants have been obligingly sucking it back out again.
