A newly released climate assessment from the Antigua and Barbuda Meteorological Service has confirmed that 2026 will go down in the archipelago’s weather history books, after Antigua logged its third driest May since systematic rainfall tracking began nearly a century ago in 1928. The official Monthly Climate Summary, published in June to review May’s conditions, paints a stark picture of sustained dry conditions that have rapidly intensified drought across both islands of the Caribbean nation.

Across the entire island of Antigua, the average rainfall recorded for May amounted to just 17.5 millimeters, or 0.69 inches. At the V.C. Bird International Airport monitoring site, one of the archipelago’s longest-running weather stations, only 14.2 millimeters (0.56 inches) of rain fell throughout the entire month, placing this May as the fifth driest on record for that location since 1928.

Meteorologists analyzing the data note that drought conditions have grown steadily more severe across the country over recent months. The Standardized Precipitation Index, a widely used global metric for measuring dryness relative to long-term averages, classified northern Antigua as facing severe drought, while the rest of the island fell into the moderate drought category for May. This dry pattern did not emerge suddenly: the three-month period from March through May 2026 was also categorized as severely dry across the entirety of Antigua, and the dry spell stretches back even further. For the six-month window from December 2025 through May 2026, northern Antigua remains in severe drought, with the rest of the island still classified as moderately dry.

Notably, temperatures across the archipelago remained close to the long-term seasonal average for May, despite the near-complete lack of rainfall. At V.C. Bird International Airport, the average daily mean temperature clocked in at 26.9 degrees Celsius (80.4 degrees Fahrenheit), with an average daily high of 29.9 degrees Celsius (85.8 degrees Fahrenheit). The hottest temperature recorded at the airport for the month hit 30.4 degrees Celsius (86.7 degrees Fahrenheit) on May 31. Island-wide, the average temperature for Antigua settled at 27.4 degrees Celsius (81.3 degrees Fahrenheit), and the highest temperature recorded anywhere on the island reached 34.7 degrees Celsius (94.5 degrees Fahrenheit) at the Five Islands coastal location, also measured on May 31.

Rainfall, when it did occur, was extremely unevenly distributed across Antigua, with the southern and southwestern regions recording the bulk of the limited precipitation. The Donkey Sanctuary monitoring site in St. Paul recorded the highest total monthly rainfall across the island at 83.8 millimeters (3.30 inches), while Cobbs Cross saw the single wettest 24-hour period, when 30.7 millimeters (1.21 inches) fell on May 25.

For the neighboring island of Barbuda, official monitoring recorded just 15.8 millimeters (0.62 inches) of total rainfall throughout May. The island saw only five days with measurable precipitation, and endured a continuous 14-day dry stretch during the month. At the Sir McChesney George Secondary School monitoring station, the average daily mean temperature for May was 27.5 degrees Celsius (81.5 degrees Fahrenheit). While limited on-the-ground monitoring data prevents meteorologists from issuing a definitive drought classification for Barbuda, satellite-based precipitation estimates indicate the island is facing dry conditions nearly identical to those impacting Antigua, the report confirmed.

As humanity stands at the threshold of a new era of lunar exploration, two ambitious global initiatives – NASA’s Artemis Program and the collaborative International Lunar Research Station (ILRS) – are reshaping what we once thought possible for off-Earth scientific discovery and long-term space habitation. This second installment of the commentary series delves deeper into how these parallel projects, far from being purely competing efforts, are creating complementary pathways that could accelerate progress toward humanity’s next giant leap: sending the first crewed missions to Mars.

Decades after the final Apollo mission returned to Earth, the Artemis Program reignited global public interest in lunar exploration, with a core mission to land the first woman and first person of color on the lunar south pole. This region, permanently shadowed craters hold vast reserves of water ice – a resource that could be broken down into oxygen for breathing and hydrogen for rocket fuel, transforming the Moon from a dead rock we only visit into a viable refueling stop for deeper space missions. Beyond symbolic milestones, Artemis has already laid critical groundwork: developing the Space Launch System (SLS) rocket, the Orion crew capsule, and partnering with private aerospace companies like SpaceX to build the lunar lander that will carry humans back to the surface by 2025 or 2026, delayed only slightly by technical and budgetary hurdles. In parallel, the ILRS, a collaborative project led by the China National Space Administration (CNSA) and Roscosmos with open invitations to global space agencies and scientific institutions, is focused on building a permanent, continuously crewed research outpost on the lunar surface by the 2030s. Its core goals align closely with many of Artemis’ long-term objectives: studying lunar geology, testing in-situ resource utilization technologies, and preparing for the extreme conditions of deep space travel.

Critics have framed the two programs as a new space race, echoing the geopolitical tensions of the 1960s Apollo era. But many space policy analysts and planetary scientists argue that this framing misses the bigger picture. Across the global space community, there is growing recognition that even separate projects generate shared knowledge that benefits all of humanity. Data on lunar surface conditions, new life support technologies, and lessons learned about long-duration habitation in a reduced-gravity environment will all be openly shared in many scientific forums, lowering the risk and cost of future exploration for every participating nation.

What makes this moment a true turning point for human spaceflight is not just the technology, but the broader participation. Unlike the mid-20th century space race, which was driven by geopolitical rivalry between two superpowers, today’s lunar efforts include contributions from private industry, smaller national space agencies, and academic institutions from every inhabited continent. This collaborative, open model creates a sustainable foundation for expansion that the early Apollo program never had. The long-term vision shared by both initiatives is clear: to turn the Moon into a testing ground for the technologies and systems that will allow humans to survive the 6-month journey to Mars, establish the first human outpost on another planet, and answer one of humanity’s oldest questions: are we alone in the universe?

As both programs move through their development and early mission phases in the coming years, the choices made today – from how we share scientific data to how we structure international cooperation – will define the trajectory of human space exploration for generations. This is not just a race to the Moon; it is humanity’s collective preparation for the next giant leap into the unknown.

On June 8, 2026, World Oceans Day, the United Nations officially unveiled its Third World Ocean Assessment (WOA III), the most comprehensive global audit of Earth’s marine environment ever compiled, with a leading Caribbean climate scientist playing a central role in steering the landmark initiative.

Unlike fragmented regional or single-issue ocean studies, WOA III stands alone in its holistic approach, examining the entire interconnected marine system rather than breaking it into isolated segments. The project drew together more than 580 leading scientists and policy experts from 86 nations across the globe, pooling decades of on-the-ground research, satellite data, and community observations to create an evidence-backed roadmap for global ocean stewardship. Donovan Campbell, a professor of geography at the University of the West Indies (UWI) Mona Campus and director of the university’s Western Jamaica Campus, was tapped as one of just 25 global lead experts for the assessment, guiding its strategic framework and scientific integrity through every stage of development.

For Campbell, a specialist in climate action and social equity who has spent decades collaborating with Caribbean governments and local communities to build climate-resilient development, the opportunity to lead the assessment was a landmark professional honor. “What sets WOA III apart is that it treats the ocean as a single connected system, weighing its environmental health alongside the economies and societies that depend on it. That is the only way to see clearly what is at stake and what must be done,” he explained in remarks following the report’s launch.

The 2026 assessment outlines a stark portrait of growing systemic pressure on the world’s oceans, documenting accelerating trends including rising ocean temperatures, widespread degradation of critical marine ecosystems, shifting fisheries productivity, accelerating sea-level rise, and mounting strain on coastal communities worldwide. To reverse these damaging trajectories, the report emphasizes that urgent, coordinated action is needed: science-backed regulatory policies, large-scale ecosystem protection initiatives, sustainable management of marine natural resources, and far stronger cross-border collaboration between nations and global institutions.

For Jamaica and the broader Caribbean region, the WOA III findings carry particularly urgent weight. The region’s core economic sectors—from traditional industries such as tourism, commercial fisheries, maritime transport, and coastal development to fast-growing emerging blue economy segments—are entirely dependent on healthy, functional marine ecosystems. At the same time, Small Island Developing States (SIDS) across the Caribbean are among the most vulnerable nations on Earth to climate-driven ocean impacts, already facing widespread coral reef die-offs, accelerating coastal erosion, more intense and destructive tropical cyclones, and chronic sea-level rise that threatens coastal communities and infrastructure.

Campbell stressed that ocean sustainability is not an environmental afterthought for Caribbean SIDS, but a core requirement for economic stability, social well-being, and long-term development. “The Caribbean has a profound stake in the future of the ocean. For Jamaica and other Small Island Developing States, ocean sustainability is an economic, social, and developmental imperative,” he said. “The assessment reinforces the need for evidence-based policy, stronger ocean governance, sustainable ocean planning, and sustained investment in resilience, conservation, and sustainable ocean industries.”

As the global community works toward meeting the United Nations Sustainable Development Goals by 2030, WOA III is expected to serve as a foundational reference tool for policymakers, academic researchers, international development agencies, and intergovernmental organizations for the next decade. Campbell’s leadership role in the initiative also underscores the UWI’s longstanding standing as a global leader in scientific research and policy development focused on climate action, ocean sustainability, and equitable sustainable development, particularly for small island and coastal developing nations.

After more than two years since the last total solar eclipse crossed North America, sky enthusiasts across the Northern Hemisphere are gearing up for a rare celestial display on August 12, when the moon will align perfectly between the sun and Earth to block out all direct sunlight for observers along a narrow, transcontinental path.

Defined by NASA as a phenomenon where the moon’s full shadow falls across Earth, completely obscuring the sun from view in select regions, a total solar eclipse splits audiences into two experience groups this year. Those positioned along the 5,157-mile (8,300-kilometer) path of totality will get to witness the breathtaking moment of totality, when midday skies darken abruptly and the sun’s faint outer corona becomes visible to the naked eye. This path kicks off near the Arctic coastline around 1 p.m. ET, sweeps past the North Pole, and then moves through parts of Greenland, Iceland, northeastern Portugal, and northern Spain before ending near sunset.

Observers outside this narrow corridor will still get to see a partial eclipse, where only a portion of the sun is blocked by the moon. The partial event will be visible across large swathes of Europe, Africa, and North America.

For mainland Spain, this August eclipse marks an unprecedented milestone: it is the first total solar eclipse visible from the Spanish mainland since 1905, per data from the European Space Agency (ESA). It is also the opening act of three total solar eclipses that will pass over Spain between 2026 and 2028. The last total solar eclipse visible from mainland Europe dates all the way back to 2005, making this year’s event a once-in-a-generation opportunity for many European sky-gazers.

“A total solar eclipse is one of those rare moments when millions of people can look up together and feel both wonder and curiosity,” Carole Mundell, ESA’s director of science, said in an official statement. “It is a shared moment that connects us to the Universe and reminds us that the desire to explore and understand is one of humanity’s greatest strengths.”

The length of totality varies greatly across the path this year. Greenland observers can expect just over two minutes of complete darkness, while viewers in northern Spain will only see roughly 20 seconds of totality, assuming clear weather. Unfavorable cloudy conditions remain the most common barrier to successful eclipse viewing, and the event will reach Spanish Galicia and the Balearic Islands as sunset approaches, which will amplify the already dramatic shift from daylight to darkness.

For astronomy fans unable to travel to the path of totality, ESA will host a free public livestream of the event from Spain’s Astrophysical Observatory of Javalambre in Teruel, bringing the celestial spectacle directly to viewers around the globe.

Looking ahead, the next total solar eclipse will cross southern Spain, North Africa, Saudi Arabia, and Yemen on August 2, 2027. For the contiguous United States, the next chance to see a total solar eclipse will not come until August 22, 2044, when totality will sweep across North Dakota and Montana. A coast-to-coast total solar eclipse crossing 11 of the Lower 48 states, from California to Florida, is scheduled for August 12, 2045.

Along with the public excitement, this year’s eclipse also presents major scientific opportunities. Spanish researchers plan to repeat the famous 1919 solar eclipse experiment that first confirmed Albert Einstein’s groundbreaking theory of general relativity by measuring how the sun’s gravity bends light from distant stars. High-altitude balloons will be launched to capture images of the eclipse and the moon’s shadow across Earth’s surface to replicate the historic experiment. Citizen scientists are also invited to participate by building their own simple measurement tools to track atmospheric changes that occur during the sudden darkening of the sky.

Beyond fundamental research, ESA sees the eclipse as a powerful outreach tool. “We use moments like this to bring space science and technology closer to society, to inspire future generations and bring people across Europe together through the excitement of discovery,” Mundell noted.

NASA reminds all viewers to follow critical safety guidelines to avoid permanent eye damage. Looking directly at the sun is only safe during the brief period of full totality; as soon as the first sliver of sunlight reappears, observers must use certified eclipse glasses or handheld solar filters to view the event. Regular sunglasses are not sufficient, as they are thousands of times lighter than the international safety standard required for solar viewing. Observers should also never use unfiltered optical devices such as cameras, telescopes, or binoculars even while wearing eclipse glasses, as concentrated solar rays can burn through protective filters and cause severe eye injury. Damaged, scratched, or torn eclipse gear should be discarded immediately to avoid risk.
