IPCC Climate Change Report Finds That Major Climate Changes Are Inevitable and Irreversible

The United Nations formed the Intergovernmental Panel on Climate Change (IPCC) to inform national governments about the science and potential impacts of climate change. Humans have heated the planet by roughly 1.1°C since the 19th century, mainly from burning coal, oil, and gas for energy. 

The consequences of global warming can be seen this summer alone, with heatwaves across the US and Canada, floods devastating Germany and China, and wildfires are raging out of control across the world. Unless immediate, rapid, and large-scale action is taken to reduce emissions, the report says, the average global temperature is likely to reach or cross the 1.5°C warming threshold within 20 years. 

Some key points from the IPCC report:

• Global surface temperature was 1.09C higher in the decade between 2011-2020 than between 1850-1900.

• The past five years have been the hottest on record since 1850

• The recent rate of sea level rise has nearly tripled compared with 1901-1971

• Human influence is "very likely" (90%) the main driver of the global retreat of glaciers since the 1990s and the decrease in Arctic sea-ice

• It is "virtually certain" that hot extremes including heat waves have become more frequent and more intense since the 1950s, while cold events have become less frequent and less severe

While this report is more clear and confident about the downsides to warming, the scientists are more hopeful that if we can cut global emissions in half by 2030 and reach net zero by the middle of this century, we can halt and possibly reverse the rise in temperatures. 

Reaching net-zero involves reducing greenhouse gas emissions as much as possible using clean technology, then burying any remaining releases using carbon capture and storage or absorbing them by planting trees.

According to a draft of an upcoming IPCC scientific report, some lifestyle changes could also cut emissions twice the size of Brazil’s current emissions by 2030. Changes include heating and cooling set-point adjustments, reducing appliance use, shifting to human-centered mobility and public transit, reduced air travel, and improved recycling. The draft IPCC found that individual behavior change in isolation cannot reduce greenhouse gas emissions significantly, but individuals can contribute to overcoming barriers and enable climate change mitigations. 

The full second report, set to be released in 2022, will detail how climate change might affect human society, such as coastal cities, farms, or health care systems. A third report, also expected next year, will explore more fully strategies to reduce greenhouse gas emissions and halt global warming.

Canadian Public Health Experts Discuss Pros and Cons of Disclosing COVID Outbreaks at Businesses

An article by the Canadian Medical Association Journal (CMAJ) discussed the ethics and concerns of disclosing the names of businesses where COVID-19 outbreaks have occurred. When an outbreak of infection at a workplace is identified, standard public health practice is to publicly reveal the name of the workplace only if all contacts cannot be traced and a risk to the public is identified. 

In Canada, many larger cities such as Toronto and Hamilton have a reporting policy. In contrast, Ontario has no approach to reporting since the decision is left up to administrators of local health units. The authors of the article talk about the pros and cons of providing information to the public that could be seen as essential in letting a person make an informed decision on whether they want to visit a particular business. 

However, there are also many reasons that businesses may not publicly state that their workplace had an outbreak, the most prominent being people’s right to privacy. The article believes that it is vital to protect workers from stigma, public shaming, and harassment that could be associated with COVID-19. "Moreover, businesses that are outed as having an outbreak of infectious disease may face serious consequences that in turn may lead to loss of employment for workers and downstream effects for local economies," said the article.

An argument for letting employers know about outbreaks is that people are more likely to cooperate with efforts of the public health agencies to control an outbreak by allowing rapid access and intervention to protect workers. Ontario’s stay-at-home order expired on June 2nd, but existing restrictions on gathering, businesses, services, and activities will remain in effect for the time being. This includes limiting outdoor gatherings to up to five people, limiting essential retail capacity to 25%, restricting non-essential retail to do curbside pick-up and delivery, and prohibiting indoor gatherings. 

In the US, there are 28 OSHA-approved State Plans that set standards and enforcement programs and must be at least as effective as OSHA in protecting workers and in preventing work-related injuries, illnesses, and death. 

In conclusion, the article in the CMAJ states that more collaboration is needed between public health agencies and workplaces to ensure that such things as paid sick leave and better infection controls come into play. 

Identifying Counterfeit and Fake N95 Masks

Approximately 10 million fake 3M N95 masks have been distributed in at least five states, and federal, and state authorities are managing to seize and cease the counterfeit ring. The masks are designed to mimic 3M N95 masks, with details including raised marking and printed logos. As a response, 3M has issued a warning describing the model and lot numbers to look out for when purchasing masks. 

The National Institute of Occupational Safety and Health (NIOSH) has also released a guide on how to spot masks that are falsely claimed to be approved by the NIOSH. NIOSH-approved masks will have an official approval label on or within the packaging, and the filtering facepiece respirator (FFR) of the N95 masks should also have an abbreviated approval. 

The NIOSH Certified Equipment List (CEL) or the NIOSH Trusted-Source page can be used as a resource to verify and determine whether NIOSH has approved the respirator. The approved FFRs include N95, N99, N100, R95, R99, R100, P95, P99, and P100.  

Signs that a respirator may be counterfeit:

• No markings at all on the filtering facepiece respirator (FFR).

• No approval (TC) number on FFR or headband.

• No NIOSH markings.

• NIOSH spelled incorrectly.

• Presence of decorative fabric or other decorative add-ons (e.g., sequins).

• Claims of approval for children (NIOSH does not approve any type of respiratory protection for children).

• FFR has ear loops instead of headbands.

NIOSH also offers additional tips on how to identify counterfeit masks, including third-party marketplaces. Some things to consider include: 

• If a listing claims to be “legitimate” and “genuine,” it likely is not.

• Examine transactions history and feedback if possible

• Look for fluctuations of items traded over time (high or low transaction periods)

• Look for price deviations and fluctuations (Is it too good to be true?)

• Look at the quantity a buyer has in stock.

• During a time of shortage, advertising “unlimited stock” could indicate that the respirator is not approved.

• Does the seller break marketplace policy and hide their contact information within images to circumvent filters.

OSHA Proposes Updates to Hazard Communication Standard

The Occupational Safety and Health Administration (OSHA) is scheduled to publish a notice of proposed rule update to its Hazard Communication (“Haz Com”) Standard on February 16th, 2021. This proposed change will align its rules with those in the seventh version of the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS).

OSHA’s Haz Com was initially established in 1983, and it provides a systematized approach to communicating workplace hazards associated with exposure to hazardous chemicals. The Haz Com Standard is currently linked to the third version of GHS, which was created in 2012. In the Haz Com Standard, chemical manufacturers are required to classify the hazards of chemical which they produce or import into the US, and employers need to provide information to their employees about the hazardous chemicals to which they are exposed. This includes providing a hazard communication program, labeling and other forms of warning, safety data sheets, and training. The notice of proposed rulemaking will enhance worker protections by updating the Haz Com Standard, which should support more extensive efforts to address workplace hazards such as aggregate exposures and cumulative risk models. 

Some other key modifications included in the proposed rule include:

• New flexibility for labeling bulk shipments of hazardous chemicals, including allowing labels to be placed on the immediate container or transmitted with shipping papers, bills of loading, or by other technological or electronic means that are immediately available to workers in printed form on the receiving end of the shipment;

• New alternative labeling options where a manufacturer or importer can demonstrate that it is not feasible to use traditional pull-out labels, fold-back labels, or tags containing the full label information generally required under the Haz Com Standard, including specific alternative requirements for containers less than or equal to 100ml capacity and for containers less than or equal to 3ml capacity; and

• New requirements to update the labels on individual containers that have been released for shipment but are awaiting future distribution where the manufacturer, importer, or distributor become aware of new significant information regarding the chemical’s hazards.

OSHA will be accepting comments on the proposed rule until April 19th, 2021. Comments can be submitted at https://www.regulations.gov/. 

New COVID Testing Guidance Requiring Employers To Obtain Informed Consent

The Centers for Disease Control and Prevention (CDC) recently issued new guidance that will require employers to get informed consent from employees before testing them for COVID-19. In October, the CDC released guidance on employer testing, but it did not issue revised guidance containing the informed consent requirement until January 21. The new guidance states that “informed consent required disclosure, understanding, and free choice and is necessary for an employee to act independently and make choices according to their values, goals, and preferences.”

Earlier guidance issued by the Equal Employment Opportunity Commission (EEOC) also directed employers to obtain informed consent before testing. The CDC recommends employers to provide the workers who will be tested with “complete and understandable information about how the employer’s testing program may impact employee’ lives, such as if a positive test result or declination to participate in testing may mean exclusion from work.” 

According to the CDC, a few things for an employer to consider when developing a COVID testing program should be:

• Why is the employer offering the test to begin with?

• How frequently will employees be tested?

• How to effectively obtain employee consent.

• What to do if an employee declines to be tested.

The CDC also offers a list of key measures an employer should implement when developing a testing program to ensure that informed consent is obtained, including:

• Ensure safeguards are in place to protect an employee’s privacy and confidentiality.

• Provide complete and understandable information about how the employer’s testing program may impact employees’ lives, such as if a positive test result or declination to participate in testing may mean exclusion from work.

• Explain any parts of the testing program an employee would consider especially important when deciding whether to participate. This involves explaining the key reasons that may guide their decision.

• Provide information about the testing program in the employee’s preferred language using non-technical terms. Consider obtaining employee input on the readability of the information. Employers can use this tool to create clear messages.

• Encourage supervisors and co-workers to avoid pressuring employees to participate in testing.

• Encourage and answer questions during the consent process. The consent process is active information sharing between an employer or their representative and an employee, in which the employer discloses the information, answers questions to facilitate understanding, and promotes the employee’s free choice.
