Climate Science:  An Update

Al Hammond • June 27, 2019

Some impacts of a changing climate are increasingly evident: more severe storms (as in hurricanes and tornados), more intense rainfall and flooding (as in the Mid-West this spring), more drought and forest fires (as in California). Others are more subtle: gradually warmer temperatures, rising sea levels, changing fisheries, starving polar bears (as polar ice melts).

The underlying causes of these changes are well known and well documented—if also frequently denied by, among others, the President of the United States. What warms the Earth is radiation from the sun. Much of that radiation is re-radiated from Earth’s surface to space, but as longer wavelength, infra-red radiation. So-called greenhouse gases in the atmosphere—especially carbon dioxide and methane—absorb that radiation, trapping the resulting heat and warming the atmosphere. As concentrations of these gases increase, principally from combustion of coal, oil, and natural gas, but also from growing livestock herds (who emit methane) raised for meat, so will the warming. For more than 60 years, scientists have documented a steady growth in greenhouse gas concentrations in the atmosphere and rising atmospheric temperatures.

The atmospheric warming is most pronounced in the polar regions, hastening the melting of the Arctic sea ice, the Greenland ice cap, and the massive south polar ice cap—all of which drive sea level rise. The warmer atmosphere affects weather patterns, leading to more frequent intense storms such as hurricanes and to increased rain and flooding in some regions and increased drought in others. A serious, persistent drought in parts of Central America that has made it impossible for many small farmers to feed their families is a major cause of increased migration from that region to the U.S. Likewise, sustained drought has dried out the forests of the western U.S., leading to more numerous and intense forest fires—which in turn release more carbon dioxide to the atmosphere.

The warmer atmosphere also leads to warming of the upper layers of the ocean and to higher concentrations of carbon dioxide in the seawater, making the marine environment more acidic. Warmer ocean water both expands (adding to sea level rise) and impacts marine life, since warmer water contains less oxygen. (Yes, fish and other marine animals need oxygen to survive, just like people). Warmer water also evaporates more rapidly, adding to the moisture in the atmosphere and hence to the likelihood of intense rainfall and flooding. A more acidic ocean may impair the photosynthetic ability of algae and microbes to produce oxygen (half of atmospheric oxygen we breathe comes from the oceans).

Natural processes such as the growth of trees can remove carbon dioxide from the atmosphere, but only slowly; at present the average life of a carbon dioxide molecule in the atmosphere is at least 100 years, and we are adding carbon dioxide much faster than it can be removed. That means we (and our descendants) are already committed to some significant amount of additional warming and sea level rise. Already, the costs for protecting coastal urban areas against rising seas are estimated at $5-$10 billion per city, just for sea walls (not counting the costs of redoing water and sewer systems or re-locating whole neighborhoods). Experts think most smaller coastal communities, and perhaps those along flood-prone rivers, will have to be abandoned.

Climate skeptics point out that models can’t yet predict the timing and impacts of climate change in specific areas with any accuracy. That’s not surprising; even daily weather predictions are often wrong, let alone predictions months or years in advance. At the level of the entire Earth, however, there is virtually no doubt that human activities have set in motion significant—and for the most part unwelcome—changes to the climate. Moreover, the scientific consensus is that we have only a couple of decades to take major steps—such as shifting the majority of our energy needs to renewable energy sources—before we are committed to changes that will significantly alter life on earth for generations to come.

Common Sense for the Eastern Shore

By Friends of Megan Outten July 29, 2025
Megan Outten, a lifelong Wicomico County resident and former Salisbury City Councilwoman, officially announced her candidacy recently for Wicomico County Council, District 7. At 33, Outten brings the energy of a new generation combined with a proven record of public service and results-driven leadership. “I’m running because Wicomico deserves better,” Outten said. “Too often, our communities are expected to do more with less. We’re facing underfunded schools, limited economic opportunities, and years of neglected infrastructure. I believe Wicomico deserves leadership that listens, plans ahead, and delivers real, measurable results.” A Record of Action and A Vision for the Future On Salisbury’s City Council, Outten earned a reputation for her proactive, hands-on approach — working directly with residents to close infrastructure gaps, support first responders, and ensure everyday voices were heard. Now she’s bringing that same focus to the County Council, with priorities centered on affordability, public safety, and stronger, more resilient communities. Key Priorities for District 7: Fully fund public schools so every child has the opportunity to succeed. Fix aging infrastructure and county services through proactive investment. Keep Wicomico affordable with smarter planning and pathways to homeownership. Support first responders and safer neighborhoods through better tools, training, and prevention. Expand resources for seniors, youth, and underserved communities. Outten’s platform is rooted in real data and shaped by direct community engagement. With Wicomico now the fastest-growing school system on Maryland’s Eastern Shore — and 85% of students relying on extra resources — she points to the county’s lagging investment as a key area for action. “Strong schools lead to strong jobs, thriving industries, and healthier communities,” Outten said. “Our schools and infrastructure are at a tipping point. We need leadership that stops reacting after things break — and starts investing before they do.” A Commitment to Home and Service Born and raised in Wicomico, Megan Outten sees this campaign as a continuation of her lifelong service to her community. Her vision reflects what she’s hearing from neighbors across the county: a demand for fairness, opportunity, and accountability in local government. “Wicomico is my home; it’s where I grew up, built my life, and where I want to raise my family,” Outten said. “Our county is full of potential. We just need leaders who will listen, work hard, and get things done. That’s what I’ve always done, and that’s exactly what I’ll continue to do on the County Council.” Outten will be meeting with residents across District 7 in the months ahead and unveiling more details of her platform.

Way back in 1935, the Supreme Court determined that independent agencies like the Consumer Product Safety Commission (CPSC), the National Labor Relations Board (NLRB) and the Merit Systems Protection Board (MSPB) do not violate the Constitution’s separation of powers. Humphrey’s Executor v. United States (1935). Congress provided that the CPSC, like the NLRB and MSPB, would operate as an independent agency — a multi-member, bipartisan commission whose members serve staggered terms and could be removed only “for neglect of duty or malfeasance in office but for no other cause.” Rejecting a claim that the removal restriction interferes with the “executive power,” the Humphrey’s Court held that Congress has the authority to “forbid their [members’] removal except for cause” when creating such “quasi-legislative or quasi-judicial” bodies. As a result, these agencies have operated as independent agencies for many decades under many different presidencies. Shortly after assuming office in his second term, Donald Trump began to fire, without cause, the Democratic members of several of these agencies. The lower courts determined to reinstate the discharged members pending the ultimate outcome of the litigation, relying on Humphrey’s , resulting in yet another emergency appeal to the Supreme Court by the administration. In the first such case, a majority of the Court allowed President Trump to discharge the Democratic members of the NLRB and the MSPB while the litigation over the legality of the discharges continued. Trump v. Wilcox (May 22, 2025). The majority claimed that they do not now decide whether Humphrey’s should be overruled because “that question is better left for resolution after full briefing and argument.” However, hinting that these agency members have “considerable” executive power and suggesting that “the Government” faces greater “risk of harm” from an order allowing a removed officer to continue exercising the executive power than a wrongfully removed officer faces from being unable to perform her statutory duty,” the majority gave the President the green light to proceed. Justice Kagan, joined by Justices Sotomayor and Jackson, dissented, asserting that Humphrey’s remains good law until overturned and forecloses both the President’s firings and the Court’s decision to award emergency relief.” Our emergency docket, while fit for some things, should not be used to “overrule or revise existing law.” Moreover, the dissenters contend that the majority’s effort to explain their decision “hardly rises to the occasion.” Maybe by saying that the Commissioners exercise “considerable” executive power, the majority is suggesting that Humphrey’s is no longer good law but if that is what the majority means, then it has foretold a “massive change” in the law and done so on the emergency docket, “with little time, scant briefing, and no argument.” And, the “greater risk of harm” in fact is that Congress provided for these discharged members to serve their full terms, protected from a President’s desire to substitute his political allies. More recently, in the latest shadow docket ruling in the administration’s favor, the same majority of the Court again permitted President Trump to fire, without cause, the Democratic members of another independent agency, this time the Consumer Product Safety Commission (CPSC). Trump v. Boyle (July 23, 2025). The same three justices dissented, once more objecting to the use of the Court’s emergency docket to destroy the independence of an independent agency as established by Congress. The CPSC, like the NLRB and MSPB, was designed to operate as “a classic independent agency.” In Congress’s view, that structure would better enable the CPSC to achieve its mission — ensuring the safety of consumer products, from toys to appliances — than would a single-party agency under the full control of a single President. “By allowing the President to remove Commissioners for no reason other than their party affiliation, the majority has negated Congress’s choice of agency bipartisanship and independence.” The dissenters also assert that the majority’s sole professed basis for the more recent order in Boyle was its prior order in Wilcox . But in their opinion, Wilcox itself was minimally explained. So, the dissenters claim, the majority rejects the design of Congress for a whole class of agencies by “layering nothing on nothing.” “Next time, though, the majority will have two (if still under-reasoned) orders to cite. Truly, this is ‘turtles all the way down.’” Rapanos v. United States (2006). * ***** *In Rapanos , in a footnote to his plurality opinion, former Supreme Court Justice Scalia explained that this allusion is to a classic story told in different forms and attributed to various authors. His favorite version: An Eastern guru affirms that the earth is supported on the back of a tiger. When asked what supports the tiger, he says it stands upon an elephant; and when asked what supports the elephant, he says it is a giant turtle. When asked, finally, what supports the giant turtle, he is briefly taken aback, but quickly replies "Ah, after that it is turtles all the way down." John Christie was for many years a senior partner in a large Washington, D.C. law firm. He specialized in anti-trust litigation and developed a keen interest in the U.S. Supreme Court about which he lectures and writes.

Right now, Congress is working on a fast-track bill that would make historic cuts to basic needs programs in order to finance another round of tax breaks for the wealthy and big corporations.

The House Agriculture Committee recently voted, along party lines, to advance legislation that would cut as much as $300 million from the Supplemental Nutrition Assistance Program. SNAP is the nation’s most important anti-hunger program, helping more than 41 million people in the U.S. pay for food. With potential cuts this large, it helps to know who benefits from this program in Maryland, and who would lose this assistance. The Center on Budget and Policy Priorities compiled data on SNAP beneficiaries by congressional district, cited below, and produced the Maryland state datasheet , shown below. In Maryland, in 2023-24, 1 in 9 people lived in a household with SNAP benefits. In Maryland’s First Congressional District, in 2023-24: Almost 34,000 households used SNAP benefits. Of those households, 43% had at least one senior (over age 60). 29% of SNAP recipients were people of color. 15% were Black, non-Hispanic, higher than 11.8% nationally. 6% were Hispanic (19.4% nationally). There were 24,700 total veterans (ages 18-64). Of those, 2,200 lived in households that used SNAP benefits (9%). The CBPP SNAP datasheet for Maryland is below.
