Climate change: Can 12 billion tonnes of carbon be sucked from the air?

Every year. For decades to come. That's the challenge posed by the latest conclusions of the UN's climate science panel. It says that only by pulling this heat-trapping gas out of the atmosphere can we avoid dangerous climate change. But according to one leading researcher, there's a bit of a hitch: "We haven't a clue how to do it". The problem is that scientists reckon that even if the world manages to cut emissions of the gas, it will no longer be enough to avoid the worst impacts. We've got to go a step further, they say, and find ways of doing something never attempted before: get rid of the gas that's already out there.

What ideas are around? The most headline-grabbing solution is for giant machines to filter the air and strip out the gas, as my colleague Matt McGrath has reported. This happens all the time naturally but took off in spectacular fashion more than 400 million years ago. Twitter. A metaphor for humanity’s attitude towards the ecological crisis. Twitter.

The most effective individual steps to tackle climate change aren't being discussed

Published today in the journal Environmental Research Letters, the study from Lund University, found that the incremental changes advocated by governments may represent a missed opportunity to reduce greenhouse gas emissions beneath the levels needed to prevent 2°C of climate warming. The four actions that most substantially decrease an individual's carbon footprint are: eating a plant-based diet, avoiding air travel, living car-free, and having smaller families. The research analysed 39 peer reviewed papers, carbon calculators, and government reports to calculate the potential of a range of individual lifestyle choices to reduce greenhouse gas emissions. This comprehensive analysis identifies the actions individuals could take that will have the greatest impact on reducing their greenhouse gas emissions. Twitter. This heatwave is just the start.

Britain is so hot and dry that we have Indonesia-style peat fires raging across our moorlands. Montreal posted its highest temperature ever, with the deaths of 33 people in Quebec attributed to the scorching heat. And if you think that’s hot and dangerous, the town of Quriyat in Oman never went below a frightening 42.6C for a full 24 hours in June, almost certainly a global record. While many people love a bit of sun, extreme heat is deadly. Climate change: Michael Bloomberg pledges $4.5m for Paris deal.

He said he had a responsibility to help improve the environment because of President Donald Trump's decision to pull out of the deal. The withdrawal was announced last June and sparked international condemnation. It will make the US in effect the only country not to be part of the Paris accord. The Paris agreement commits the US and 187 other countries to keeping rising global temperatures "well below" 2C above pre-industrial levels.

Zambian farmers benefit from millions in insurance pay-outs thanks to Reading data. Release Date 30 January 2018 Millions of dollars are due to be paid out to small-scale farmers in Zambia affected by a recent severe dry spell, following the introduction of a new government insurance scheme powered by University of Reading science.

Zambian farmers benefit from millions in insurance pay-outs thanks to Reading data

Satellite-based rainfall estimates for Africa produced by the University’s TAMSAT research group have allowed around US$2.8m to be triggered for farmers in 370 locations in Zambia between December 1 2017 and 20 January 2018. More than a million farmers are benefiting from the new mandatory insurance scheme, introduced by the government last year to protect farmers against poor harvests due to extreme weather events. The weather index insurance scheme – the largest of its type ever run in Africa – is run by Risk Shield, which uses TAMSAT data. The scheme is integrated in the Government of Zambia’s Farmer Input Support Program (FISP).

*****Carbon capture: Climate's magic rabbit: Pulling CO2 out of thin air

Our environment correspondent Matt McGrath has travelled to Switzerland to see if technology to remove CO2 from the air could be the answer to this ongoing carbon conundrum. While CO2 concentrations are now higher than they have been in at least 800,000 years, the gas still only accounts for a tiny 0.04% of our atmosphere. However, extracting carbon dioxide from well mixed air is not just technically difficult, it's expensive as well.

*****Adaptation: This architect is trying to save our cities from rising sea levels

By 2100, there is a 90% chance that global mean sea levels will rise anywhere from eight inches to 6.6 feet, according to a recent National Oceanic and Atmospheric Administration report. As the world becomes more urbanized, cities can lose wetlands (which protect against flooding), trees (which fight CO2), and native flora and fauna. Landscape architect Kate Orff, founder of the urban design firm Scape Studio, aims to address those issues in her work. She is a 2017 recipient of the MacArthur fellowship, also known as the "genius grant," announced on October 11.

It's counterintuitive to imagine that any event spewing molten rock more than 1,000 degrees Fahrenheit could make anything cooler, yet that's precisely what volcanic eruptions do.

*****Volcanic Eruptions Can Cool the Planet, But They Won't Save Us From Climate Change

But because volcanoes are unpredictable, that impact isn't accounted for in the models of climate change we use to make decisions about carbon emissions and to set goals for mitigation—in fact, this omission is one of the biggest gaps in those models. A new paper in the journal Nature Climate Change attempts to solve the puzzle by modeling 60 different volcano scenarios and how they will impact climate. The results suggest that eruptions will likely play a role in modulating climate change over the next hundred years. Alarm as study reveals world’s tropical forests are huge carbon emission source. The world’s tropical forests are so degraded they have become a source rather than a sink of carbon emissions, according to a new study that highlights the urgent need to protect and restore the Amazon and similar regions.

Alarm as study reveals world’s tropical forests are huge carbon emission source

Researchers found that forest areas in South America, Africa and Asia – which have until recently played a key role in absorbing greenhouse gases – are now releasing 425 teragrams of carbon annually, which is more than all the traffic in the United States. This is a far greater loss than previously thought and carries extra force because the data emerges from the most detailed examination of the topic ever undertaken. The authors say their findings – published in the journal Science on Thursday – should galvanise policymakers to take remedial action. “This shows that we can’t just sit back.

The low-lying Caribbean islands inhabited by Panama's indigenous Guna people are threatened by rising sea levels and increasingly unpredictable weather.

But unlike many island communities facing such problems, the Guna have an escape plan. The tiny port of Carti on the mainland of Panama is the jumping-off place for day trippers who come to swim, splash and snorkel around the idyllic-looking islands that dot the horizon. Motor boats buzz in and out carrying smiling visitors wearing life jackets and sun hats. It's one of Panama's premier tourist destinations. The islands - almost one for every day of the year - make up the Guna Yala autonomous region, together with a strip of territory on the mainland.

Most Guna communities live on the archipelago, and have done for centuries, after they were driven offshore by disease and venomous snakes. It is the people of Gardi Sugdub - Crab Island - who are in the vanguard of the relocation project. This smart ‘tree’ has the environmental benefits of a small forest. Urban planners have a balancing act to perform.

On the one hand, green spaces in cities provide an obvious low-tech way to help remedy the growing problem of air pollution. But on the other, they are costly to maintain and space-intensive when inner-city land is at a premium. *****Adaptation: Painting roads white lowers surface temperatures by 10 degrees Celsius. Is geoengineering a bad idea? In 2010, science writer Eli Kintisch called geoengineering “a bad idea whose time has come”. It is considered by many to be the ultimate admission of our failure to curb carbon emissions – a tech-fix that excuses continued carbon gluttony in the industrialised world. A report released on Tuesday by the US National Academies of Sciences (NAS) said tinkering with the global climate now would be “irrational and irresponsible” and climate change can only be avoided by cutting emissions.

But the influential group of 16 scientists who authored the report urged policy makers to commit to further research into some geoengineering techniques. Should there come a time when the world must consider more extreme interventions in the climate, asked Marcia McNutt, the chair of the committee: “Do we want those decisions to be kneejerk reactions? Scientists are pushing wild climate hacking scenarios to save the planet.

While the planet is working on cutting emissions to curb climate change, some scientists are saying we can also help our planet out by directly messing with our atmosphere. Collectively known as geoengineering, these technology-based climate hacks could be our ticket to actively cooling down the planet, but they are untested and potentially dangerous, and therefore have remained controversial for decades. And yet scientists keep bringing them up. Now an international team of researchers has run the numbers on how we might stabilise global temperatures by using a 'cocktail' of solar geoengineering tools intended for deflecting solar radiation away from the planet.

The scientists modelled what would happen if we used sulphate particles to scatter the sun's rays in the atmosphere and simultaneously thinned out sunlight-reflecting clouds to reduce warming.

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? 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. *****Assessing threat from sea level rise: UNEP app helps coastal communities adapt to climate change - Daily Planet.
