The climate fight is global (.hindu)

The Paris accord requires vigilance by all global actors in view of the U.S.’s changed stance on climate change

Farmers from Tamil Nadu were gathered in Delhi recently, carrying skulls, apparently belonging to those among them who had committed suicide. They were seeking government assistance following the worst drought in the State in recent times. Concurrently, there are several droughts in many other parts of the world, including Bolivia and several regions of Sub-Saharan Africa. Scorched lands have led to dying livestock, withering crops, and parched communities.

Several recent extreme events such as wildfires, droughts, severe heatwaves and cyclones in other places have a clear signature of a changing climate, but in many cases these are exacerbated by other institutional failures. None of this has, however, persuaded the present U.S. government that anthropogenic greenhouse gases (GHGs) are responsible for climate change. The U.S. is still the world’s second largest annual emitter of GHGs and has generated more than a quarter of the total anthropogenic GHGs in the atmosphere since 1850.

Even though the U.S. has not technically withdrawn from the Paris Agreement from last December, when countries came together and set climate-related targets for themselves, President Donald Trump’s recent decisions are a sweeping repudiation of former U.S. President Barack Obama’s policies to reduce and limit pollution and GHGs.

The curbs on power plant emissions by the Obama administration — the Clean Power Plan (CPP) — were aimed at reducing the power sector’s carbon dioxide emissions by about a third below the 2005 levels by 2030. The regulations would require states and electric utilities to reduce emissions either by deploying renewables, reducing demand or increasing power plant efficiencies.

Effect of Trump’s actions

Mr. Trump’s orders not only directed federal agencies to cancel or amend policies that might interfere with domestic energy production, but also slashed research budgets for climate change.

In any case, the Environmental Protection Agency’s (EPA) CPP has been in the courts for more than a year due to a legal challenge mounted by over half the U.S. states and a number of companies that opposed the rule. Nevertheless, even if Mr. Trump’s order to eliminate the CPP were to go into effect, his administration is required by a 2007 U.S. Supreme Court ruling to regulate carbon dioxide. Moreover, the EPA’s rules are themselves not easy to reverse by a stroke of the presidential pen, especially given another 2009 EPA finding that GHGs “threaten the public health and welfare of current and future generations”.

How far Mr. Trump will continue to push for curbs on climate change reduction in the U.S. and any possible ripple effects from these remain to be seen. Under the circumstances, most commentators believe that his actions will have a limited impact.

Still, the recent moves by its President are a clear signal that the U.S. is no longer interested in curbing GHGs to stabilise the climate and neither is it keen to meet its Paris commitments.

Mr. Trump’s actions also demonstrate that allowing countries to write their own Nationally Determined Contributions, seen as an improvement to a global top-down approach, still has to confront the same political problem — continued implementation of the agreement by successive governments within each country. That a major emitter is retreating from its former commitments is of course a danger to the world’s climate, but this may not be a big step back if other countries persist with their efforts and if renewables continue to get more affordable as they have recently. This move also provides elbow room for renewable energy businesses elsewhere to pick up the slack in interest within the U.S.

Nonetheless, it does make one wonder how the U.S. or Europe would have responded if another country, say, India, had undertaken similar actions. There may have been little time lost before name-calling and shaming began, following which global trade sanctions would likely have been imposed, or perhaps other kinds of bans or penalties. The chance that any of this will happen now towards the U.S., still a superpower, appears to be slim.

Role of sub-national actors

Nation states are the proper agencies responsible for curbing emissions to the shared global commons. Nevertheless, Mr. Trump’s recalcitrance shows that a change in political leadership could lead to the backing out of an international treaty by any signatory. Global agreements are often tenuous and need support and pressure from other actors within and across countries who function at many levels: states, territories or provinces within a country, cities, policy think tanks, scientists, philanthropists, local communities, civil society organisations, investors, transnational groups and multinational industries.

For example, the now global movement created by 350.org and other climate protection advocacy groups in Europe and elsewhere has made impressive progress on many fronts. The regional commitments to reducing GHGs by states in large parts of the U.S., the philanthropies that are supporting improvements in efficiencies and innovations in the climate and energy sector, and cities such as New York and Seattle, which are committed to building a low-carbon future, are all examples of sub-national entities that have a powerful influence. Thus, whether it is Mr. Trump or a Democrat in the White House, the work for these players is quite important. Climate change, like democracy itself, requires vigilance and participation by both state and non-state actors.

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i...

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo...

"ISRO has capabilities to build geostationary satellites for air quality monitoring” (downtoearth)

Pawan Gupta's findings on trans-boundary movement of pollution (Punjab to Delhi) from biomass burning in 2015 spurred debates. He participated in discussions with Indian regulators early September at the Better Air Quality Conference in Busan on the advantages of using satellite data for air quality monitoring. He explains to Down to Earth how air quality monitoring is done using satellite data. How is satellite data used to measure air pollution? Satellites that provide information on atmospheric pollutants are normally (not always) in the low earth orbits (400-1000 km above the Earth’s surface). A single satellite can carry one or more remote sensing instruments onboard that look down to earth and obtain information about the object in the field of view of satellite sensor. The Earth receives electromagnetic radiation from the sun, which travels through space and reaches the earth-atmosphere system. The radiation then interacts with the Earth’s atmosphere and the surface...
