2018’s Extreme Weather Harmed UK Bumblebees
A new report from the Bumblebee Conservation Trust found that, while some rare species did well in 2018, most of the country's species of bumblebee suffered in 2018 due to both freezing weather in February and March and a summer heat wave, The Press Association reported.
How did UK #bumblebees react to the extreme weather in 2018? It was a tough year for many species, although some ra… https://t.co/2LEpkYztRZ— BBCT (@BBCT)1559113238.0
The data was based on a "BeeWalk" project in which citizen scientists walk through certain flower-rich habitats at least once a month from March to October and record the number of bees they see. In 2018, 482 people submitted data from 559 sites.
"Whilst it is great to see the four 'biggest species winners' from our latest BeeWalk data are rare bumblebees, it's concerning to see four of our seven commonest bumblebees have declined over the last nine years," Bumblebee Conservation Trust Science Manager Richard Comont said.
The bees were first harmed by the "Beast from the East" winter storm in late February and early March, which delayed the 2018 bumblebee season. Some scientists believe there is a link between the melting of Arctic sea ice due to climate change and the conditions that allow cold weather to sweep down into lower latitudes, as it did during the Beast from the East. A study published in 2018 found that warmer Arctic weather made cold winters in the Eastern U.S. and northern Europe more likely. However, the connection is not yet fully understood, as CarbonBrief explained at the time.
After the cold weather, the Bumblebee Conservation Trust found that most of the UK's 24 species of bumblebee took until July to recover and reach regular numbers. But then a summer heat wave and drought parched flowers, reducing the bees' food supply and causing their numbers to decline. Scientists calculated that climate change more than doubled the likelihood of Europe's 2018 heat wave.
The Early bumblebee (Bombus pratorum) had its worst year since 2012, which was marked by near constant rain, the Bumblebee Conservation Trust said in a press release. Other common garden bees that struggled in 2018 included the Garden bumblebee (Bombus hortorum), the Buff-tailed bumblebee (Bombus terrestris), the Heath bumblebee (Bombus jonellus) and the White-tailed bumblebee (Bombus lucorum aggregate).
On the other hand, some rare species that emerge later in the spring and enjoy hot weather had a good year. They included the Brown-banded carder bee (Bombus humilis), the Shrill carder bee (Bombus sylvarum) and the Large Garden Ruderal bumblebee (Bombus ruderatus).
The Trust worried that the events of 2018 could have implications for the future health of Britain's bumblebees:
The impact of the 2018 heatwave has raised concerns about the number of bumblebee queens that made it into hibernation over the 2018 to 2019 winter. 2018 was the worst year for bumblebee abundance – the number of individuals per species – recorded by BeeWalk since 2012. This could have a potential knock on effect on populations in 2019. The likelihood of long heatwaves like 2018 becoming more frequent could cause problems for Britain's bumblebee populations in the longer term.
Bumblebee Conservation Trust CEO Gill Perkins had advice for what bee lovers could do to give struggling pollinators a hand.
"We all need to make sure our gardens, parks and greenspaces are bumblebee-friendly to stop today's common species becoming tomorrow's rarities," she said.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
