Rocks Could Have A Role In Combatting Climate Change

They might seem solid, but rocks gradually erode. Wind, rain, ice and snow all contribute to weathering; nibbling away at mountains, sea cliffs, limestone pavements and even solid granite tors.
Freshly exposed rock surfaces react with carbon dioxide in the atmosphere to make bicarbonate ions, which flow down to the ocean (hitching a ride on rivulets of rainwater) and are used by ocean critters to make limestone. This natural process helps to keep the Earth cool by removing carbon dioxide from the atmosphere and locking it up in rocks underground for a few million years.
So could we speed up this cooling process by smashing up more rocks? German scientists have been investigating the cooling potential of two types of rock: dunite and basalt. Their results, published in Environmental Research Letters, show that, if done on a large scale (comparable with today’s coal industry), crushed basalt could mop up nearly 10% of mankind’s carbon dioxide emissions every year, while dunite could absorb double that. Basalt could also have the co-benefit of adding nutrients to soil in tropical regions.
Pricewise, the technique would cost about 10 times as much as afforestation and about two to four times as much as carbon capture and storage.

California, 17 Other States Sue Trump Administration To Defend Obama-Era Climate Rules For Vehicles

Eighteen states on Tuesday sued President Trump’s administration over its push to “reconsider” greenhouse gas emission rules for the nation’s auto fleet, launching a legal battle over one of President Barack Obama’s most significant efforts to address climate change.
Environmental Protection Agency Administrator Scott Pruitt in April said he would revisit the Obama-era rules, which aim to raise efficiency requirements to about 50 miles per gallon by 2025. Pruitt’s agency said that the standards are “based on outdated information” and that new data suggests “the current standards may be too stringent.”
But in the lawsuit, the states contend that the EPA acted “arbitrarily and capriciously” in changing course on the greenhouse gas regulations.
“This phalanx of states will defend the nation’s clean car standards to boost gas mileage and curb toxic air pollution,” California Gov. Jerry Brown (D) said in a statement announcing the suit, which was filed in the U.S. Court of Appeals for the District of Columbia Circuit.
The lawsuit comes amid a larger struggle over climate policy regarding U.S. cars and light trucks. The Trump administration has drafted a proposal that would freeze the federal standards at 2021 levels, leaving them well below levels targeted under Obama.

The Trump administration plan, which is not final, would also challenge California’s ability to set its own fuel-efficiency rules.
California has a separate set of standards that, because of the state’s huge car market, have pushed automakers to produce more fuel-efficient vehicles. According to figures from the California New Car Dealers Association, California’s 2,048,000 new car sales in 2017 represented about 12 percent of the 17 million-plus cars sold in the United States last year.
Twelve other states participating in the lawsuit — including New York — have followed California in setting more stringent emission standards. The total market involved is 36 percent of sales in the United States, according to Margo Oge, a former EPA official who helped the agency set auto regulations during the Obama years.
“If you are a car company, that is a pretty big deal. You have uncertainty how this thing is going to work out, and today you have to be investing in cars you’re going to build five years from now,” she said.
The current standards were created under a 2011 agreement reached among the Obama administration, California officials and automakers. If enacted, they would avert 6 billion tons of carbon dioxide emissions from vehicles sold between 2012 and 2025, according to the EPA.
Since the rules were issued, the transportation sector has outstripped electric power to become the top source of greenhouse gas emissions in the United States.
Congressional Democrats are mobilizing against the administration’s draft plan to weaken the rules.
“I urge you in the strongest possible terms to abandon this extreme and reckless approach, and to put the administration on a more responsible path,” wrote Sen. Thomas R. Carper (D-Del.) in a letter to Pruitt and Transportation Secretary Elaine Chao.
California has been given multiple waivers to set its own, more strict auto emissions standards, including one in 1967.
But the Trump administration is poised to argue that the state’s current efforts conflict with a 1975 law setting up federal fuel-economy standards — a contention California has vowed to fight in court.
Automakers could wind up caught in the middle of a massive legal battle, and they are divided over the Trump administration’s latest actions.
The Auto Alliance, an industry consortium, has said it backs the EPA’s moves, but executives at major automakers have balked at the plans.
“We support increasing clean car standards through 2025 and are not asking for a rollback,” Ford’s executive chairman, Bill Ford, and president and chief executive Jim Hackett, wrote last week. A top executive at Honda has also voiced concerns about where EPA is heading.
The auto industry is itself shifting toward selling cars that generate far less emissions. A report last year by Moody’s listed 18 planned or actual battery electric vehicle launches, by 11 manufacturers, between 2016 and 2020.
GM, the nation’s largest automaker, said last October that it planned to launch two new electric vehicles in the coming year and a half and 20 different models by the year 2023.
“General Motors believes in an all-electric future,” said Mark Reuss, an executive vice president with the company.
But even as the industry begins to electrify and sales for other types of green cars, like hybrids, have grown, there’s another current. Passenger cars as a whole are losing out to bigger luxury SUVs in sales trends, according to Edmunds, which collects information on automobile markets.

April 2018 Australia’s Hottest On Record Courtesy Of “Exceptional Heat”

Australia has just sweated through its hottest April (for mean temperatures) since climate records began, with top temps shattered around the nation, particularly in South Australia, New South Wales and Victoria.
The Bureau of Meteorology (BOM) earlier today released a ‘Special Climate Statement’ on the “unseasonal hot conditions which affected large parts of Australia during April 2018”.
“The hot spell impacted mainly northwest Australia in the first week of the month. It then moved southeast to affect the states of South Australia, New South Wales and Victoria – which all set April temperature records,” BOM reported.
These included:
  • 42.2°C at Nullarbor, South Australia on April 9
  • 40.5°C at Pooncarie, New South Wales on April 10
  • 39.9°C at Mildura and Hopetoun, Victoria on April 10 and April 11 respectively
BOM reports that numerous individual locations also experienced their hottest or equal-hottest April day on record, including Sydney and Adelaide. Records were also set for prolonged heat in Adelaide (three consecutive days above 35°C) and Mildura (four consecutive days above 35°C)
BOM’s Climatologist Dr Blair Trewin said the extent of the heat was exceptional, with above-average maximum temperatures extending almost nationwide.
“The heat had been building up in north western Australia since monsoon rains ended in mid-March. North westerly winds then brought the hot air mass southeast at the start of this week, which is when we saw the impacts on South Australia, Victoria and New South Wales” Dr Trewin said.
Professor Will Steffen from the Climate Council Of Australia said the ‘abnormal April’ records highlights the impact climate change is having across the country, driving more severe and more frequent heatwave events that are lasting longer than ever before.

“April 2018 alone has broken a series of climate records, and follows off the back of an already extreme summer, plagued by extreme heat, heavy rainfall, bushfires and tropical cyclones,” Professor Steffen said.
“April 9 was also named as the hottest Australian April day on record, with a national average temperature of 34.97 °C.”
Professor Steffen said the window of opportunity for Australia to tackle climate change was rapidly closing, as climate change driven extreme weather events continued across the nation.
“Australia must urgently slash its rising greenhouse gas pollution levels through continuing the transition to clean, affordable and reliable renewable energy and storage technology,” he said.
“Unfortunately, our Federal Government is lagging behind, with its proposed National Energy Guarantee (NEG) threatening to slam the brakes on Australia’s renewables and storage boom, while failing to tackle climate change through woefully inadequate emissions targets.”
“When it comes to tackling climate change, Australia cannot sit on its hands while we suffer through increasingly frequent and severe extreme weather such as the record-breaking temperatures in April.
“Many of the solutions we need to tackle climate change are already here and they are economically competitive. We’ve got to get over the political and ideological roadblocks that are stopping effective action on climate change.”

Where Women Lead On Climate Change

Christian Science Monitor - *

Women often bear the brunt of climate change's impact. In Guatemala, they also have become some of the country's most visible environmental activists.
The site of devastating landslides, fierce winds, and volcanic peaks, the hills in Guatemala's Sierra Madre can be inhospitable. But the women are just the opposite.
Last summer, dozens of women from across the country gathered to share strategies about water and forest conservation and improving crop yields, and they got a crash course in social auditing, a way for them to understand their rights and get involved in decisionmaking.
“We welcome our companions with happiness whenever they visit,” says Diega Rodriguez, one of the organizers of the Ut’z Che’ network of community forestry groups. “We have to keep working and we have to keep fighting.”
The relationships forged on those wind-whipped hills have become a kind of scaffolding for an increasingly connected network of community leaders, activists, and groups throughout the country that are working to empower women to fight for their land and their environment.
Increasingly forced to bear the brunt of more extreme weather and environmental degradation, these women are gaining the tools and the support to act on it.
The same is happening globally, as environmental justice increasingly intersects with women’s rights.
Women are urging those in power to address problems they feel most acutely, such as drought and deforestation. They’re also finding their own solutions, drawing on traditional knowledge about seeds or conservation, and leading efforts to put this knowledge to use.
As women become more empowered, they’re better able to take on leadership roles and know they have the right to do so, say advocates who support these efforts.
At the meeting in Guatemala, where much of the population depends on subsistence farming, the women spoke different languages and came from different ethnic groups, but all could share stories of how the soil was less fertile, the seasons increasingly unpredictable, and the rainfall more erratic.
“In Santa Eulalia there used to be an order of time: a month for the frost, a month for rain, a knowledge of where to farm so the frost won’t ruin the crop. Now there isn’t,” says Eulia de Leon Juarez, who helped found a women’s rights advocacy group in her town in Guatemala’s western highlands.
As in many places, problems here often revolve around water scarcity and soil degradation, conditions that increase the workload for women responsible for providing water, food, and fuel for their homes. When those resources are scarce, they must travel farther, sometimes walking for hours to reach the nearest water source.
Because women’s work is often connected to the land, women have long fought to protect their natural environments, often from extractive industries and agribusinesses that compete for access to resources. Now, some are linking this activism to the impacts they feel from a changing climate.

Building bridges
“What we’re seeing more and more now is the urgency to address these issues and really support these women so they can lead in these struggles,” says Maite Smet, a program coordinator with Global Alliance for Green and Gender Action (GAGGA), a nonprofit that brings together women's rights and environmental justice movements.
The issue has also gained traction as the number of women-led households in rural areas has grown.
“This is due to migration – men are migrating to cities – but also to conflict,” says Solange Bandiaky-Badji, Africa program director for Rights and Resources Initiative, where she focuses on land tenure rights and gender. Women “are then assuming greater responsibilities for the management and governance of the resources in their communities.”
“It’s not that it’s new,” she adds. “But these factors have helped people see that women are really working around managing their forests and resources.”
Pressures from climate change have worsened poverty, food insecurity, human trafficking, and child marriage, activists argue. For a long time, says Ms. Bandiaky-Badji, people have focused on rural and indigenous women “as victims.”
“But what we’re seeing actually,” she says, “is how these women are organizing themselves to really overcome those challenges.”
They’re doing so by challenging political and social barriers but also finding their own way forward, particularly in places like Guatemala, where political instability can often worsen environmental problems.
“In many cases, as women become involved in environmental activism, they get in touch with others and so it builds their capacity to engage with local governments and even then, to figure out how to make their stories visible on the international stage,” says Eleanor Blomstrom, co-director of the Women’s Environment and Development Organization (WEDO), a women’s advocacy group.
WEDO works to get women’s rights and gender justice included in climate change negotiations at the national and international levels. In 2015, it helped launch a program to train female climate-justice advocates to share their stories with international policymakers during climate negotiations. The organization has also created an app that tracks how often and in what way gender or women are mentioned in policies, research, and other action related to climate change.
“Women have always been leaders at all levels, it’s just not been recognized in the same way,” Ms. Blomstrom says. Part of that is a broader recognition that the effects of climate change are so varied and widespread, as well as stronger efforts to recognize women as human rights defenders.
“Even without scientists saying it, women are feeling it, so there are a lot of young feminists and activists who may be more engaged than young people were in the past or more empowered but definitely more vocal.”
Among the groups supporting those efforts is international women’s rights organization MADRE, which helps create networks where different communities around the world can share strategies for addressing climate-related problems. In late April it brought indigenous women from countries such as Nepal and Nicaragua to Arizona to hear how indigenous communities along the US-Mexico border were impacted by Trump administration policies on migration and climate change.
Women still face discrimination and resistance for taking on leadership roles, particularly in more unequal societies. Another challenge is making sure goals and plans to recognize women are put into action.

No longer invisible
Since the meeting in Guatemala in August, several women have come together to audit state-supported forestry programs that help small landowners earn money from reforestation and natural forest management. Women often face challenges participating in such programs because they lack land titles.
The group hopes to create a database of projects in a northern part of the highlands, so they can show how land tenure is distributed by gender and talk with officials about strengthening the roles that women play in environmental projects.
“We are invisible to a lot of people,” says Ms. Rodriguez.
But bringing women together to share their struggles helps improve their visibility. Since gatherings like the one last August started, topics have gone from building self-esteem to getting women more politically involved in their communities, says Dina Juc Suc, a former coordinator with Ut’z Che’, a network of dozens of community forestry organizations that helped organize the meeting.
Before the women talked about lack of education or violence they faced, says Ms. Juc Suc, who has been leading programs like these since 2010.
“Nowadays, women dare to talk about questioning a government official,” and share tips on how to adapt crops to changing weather and improve their livelihoods. “Now they are looking to create strategies,” she adds.
