What impacts have climate change mitigation strategies had on the ozone layer? This is what a recent study published in Nature hopes to address as a team of researchers led by the Massachusetts Institute of Technology (MIT) investigated the rate of Antarctic ozone recovery due to a reduction in human-caused ozone-depleting substances (ODSs). This study has the potential to help researchers, climate scientists, legislators, and the public better understand the benefits of climate change mitigation strategies on healing the environment for both the short and long term.

For the study, the researchers used a combination of satellite imagery data and a series of computer models to ascertain the extent of the Antarctic ozone recovery based on seasons and altitude between 2005 and now. The team conducted various models to identify a pattern in Antarctic ozone recovery, which they call a “fingerprint”. After comparing this to the satellite data, the team ascertained that the Antarctic ozone has been healing due to decreased levels of ODSs.

“After 15 years of observational records, we see this signal to noise with 95 percent confidence, suggesting there’s only a very small chance that the observed pattern similarity can be explained by variability noise,” said Peidong Wang, who is a PhD student in MIT’s Department of Earth, Atmospheric and Planetary Sciences and lead author of the study. “This gives us confidence in the fingerprint. It also gives us confidence that we can solve environmental problems. What we can learn from ozone studies is how different countries can swiftly follow these treaties to decrease emissions.”

A recently adopted United Nations treaty could lead to invasive digital surveillance, human rights experts warn.

By Kate Graham-Shaw

NEW YORK CITY —The United Nations approved its first international cybercrime treaty yesterday. The effort succeeded despite opposition from tech companies and human rights groups, who warn that the agreement will permit countries to expand invasive electronic surveillance in the name of criminal investigations. Experts from these organizations say that the treaty undermines the global human rights of freedom of speech and expression because it contains clauses that countries could interpret to internationally prosecute any perceived crime that takes place on a computer system.

WASHINGTON — Russia, as expected, vetoed April 24 a United Nations Security Council resolution crafted in response to reports that the country was developing a nuclear anti-satellite weapon.

Russia cast the only vote against the draft resolution that reaffirmed provisions in the Outer Space Treaty prohibiting the placement of nuclear weapons or other weapons of mass destruction in space. Thirteen other members of the Security Council voted in favor of the resolution while China abstained. As a permanent member of the Security Council, though, Russia’s vote acted as a veto preventing adoption of the resolution.

Japan and the United States drafted the Security Council resolution, which they billed as the first devoted to outer space issues. The resolution directed members to uphold Article 4 of the Outer Space Treaty, which forbids countries from placing nuclear weapons in orbit or on celestial bodies. It also called on countries not to develop nuclear weapons or other weapons of mass destruction specifically designed to be placed in orbit.

Nuclear arms are the most destructive, indiscriminate and monstrous weapons ever produced – but today, we can all celebrate a major milestone in the long march towards peace: the Treaty on the Prohibition of Nuclear Weapons (TPNW) is now part of international law!

The year 2021 also marks the 50th anniversary of Greenpeace, which began life in September 1971 when a small group of activists set sail to the island of Amchitka, off the west coast of Alaska, to try and stop nuclear weapons testing from taking place. Greenpeace could not be more delighted that in the anniversary year of our founding journey, we can join the celebration to mark this historic Treaty coming into force and pay our deepest respects to advocates for this momentous achievement, led by the International Campaign to Abolish Nuclear Weapons (ICAN).

Greenpeace France interviewed Jean-Marie Collin of ICAN France about the challenges and prospects that arise from the Treaty’s entry into force.

Although essentially the United Nations are now making nuclear weapons illegal with new treaties like nuclear disarmament. Russia currently has taken another route for globalization and possibly nuclear escalation. As currently the doomsday clock seems closer to midnight which could mean the end of the world scenarios due to Russias escalation and the possibility of all out nuclear war globally and then nuclear annihilation of the planet. Even with current wars are actually seemingly always going on but this global escalation of nuclear war is a zero sum game as no one would be the winner due to radiation levels circulating the planet. I do think that the us and china are in a treaty but so far Russia is still escalating which now holds the world now ransom.


This is a summary of Policy Brief 139 which is available with full references on the Toda Peace Institute’s website.

In January 2021, a global treaty came into force outlawing the bomb. The Treaty on the Prohibition of Nuclear Weapons (TPNW or Ban Treaty) is the most significant multilateral development in nuclear arms control since the Non-Proliferation Treaty’s (NPT) entry into force in 1970. It establishes a new normative settling point on the ethics, legality and legitimacy of the bomb.

The possession of nuclear weapons by nine countries did not suddenly became illegal with the treaty’s entry into force in January 2021. However, it would be false to claim that a UN-negotiated treaty, following a UN-authorised process and conference, has no implications for the legality and legitimacy of nuclear-weapon possession and practices.

BRUSSELS (AP) — NATO member countries that signed a key Cold War-era security treaty froze their participation in the pact on Tuesday just hours after Russia pulled out, raising fresh questions about the future of arms control agreements in Europe. Many of NATO’s 31 allies are parties to the Treaty of Conventional Armed Forces in Europe, which was aimed at preventing Cold War rivals from massing forces at or near their mutual borders. The CFE…

An international team of scientists has proposed a new remote monitoring method of nuclear stockpiles using mirrors and radio waves.

An international team of scientists has devised an innovative method of using radio waves to monitor a nation’s nuclear stockpile remotely. Conducted by a team of IT security experts from Germany and the United States, it could be used to build trust between nuclear powers to ensure rivals are keeping their promises when it comes to agreed nuclear disarmament treaties. It could also be used to give a “heads up” if one particular nuclear power removes stored nuclear warheads, which could be an indication of intended use.

Dr. Robert Floyd, Ph.D. is Executive Secretary of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO — https://www.ctbto.org/), the organization tasked with building up the verification regime of the Comprehensive Nuclear-Test-Ban Treaty, a multilateral treaty opened for signature in 1996 by which states agree to ban all nuclear explosions in all environments, for military or civilian purposes.

Prior to joining CTBTO, Dr. Floyd was the Director General of the Australian Safeguards and Non-proliferation Office (ASNO), where he was responsible for Australia’s implementation of and compliance with various international treaties and conventions including the Comprehensive Nuclear-Test-Ban Treaty, Nuclear Non-Proliferation Treaty, Convention on the Physical Protection of Nuclear Material (CPPNM) and the Chemical Weapons Convention.

During his time as Director General of ASNO, Dr. Floyd also chaired the advisory group to the Director General of the International Atomic Energy Agency on safeguards implementation (SAGSI), co-chaired the Preparatory Committee for the review of the amended CPPNM, co-chaired one of the working groups of the International Partnership for Nuclear Disarmament Verification, was the lead official for Australia in the Nuclear Security Summit process, and chaired the Asia-Pacific Safeguards Network.

Prior to his appointment with ASNO, Dr. Floyd served for more than seven years in the Department of the Prime Minister and Cabinet where he held a number of senior executive positions providing advice to the Prime Minister on policy issues covering counter-terrorism, counter-proliferation, emergency management, and homeland and border security.
