Climate monitoring and research could fall victim
to coronavirus, scientists fear
Health restrictions have already hit some long-term
projects but routine monitoring could be affected if the pandemic drags on

The
coronavirus pandemic has stalled scientific fieldwork and may even start to
affect the monitoring of the climate, scientists have warned.
Major
projects to gather environmental data have been postponed or canceled over
concerns that teams of researchers working together will spread the Covid-19
virus.
The crisis
has so far mainly stymied long-term studies, but concerns have been raised that
routine monitoring of weather and the climate crisis may be affected if the
pandemic drags on for an extended period.
Petteri
Taalas, secretary general of World Meteorological Organization, said: “The
impacts of climate change and growing amount of weather-related disasters
continue.
“The
Covid-19 pandemic poses an additional challenge, and may exacerbate
multi-hazard risks at a single-country level. Therefore it is essential that
governments pay attention to their national early warning and weather-observing
capacities despite the Covid-19 crisis.”
Wealthy
countries that have deployed land- and ocean-based instruments, as well as
satellites, to gauge temperature changes and other readings mostly have done so
with fully or partly automated systems.
This means
that data will continue to flow without much hands-on human input but should
the pandemic stretch out for many more weeks then missed repairs and
replacements of instruments will become an “increasing concern”, according to
the WMO.
Furthermore,
in many developing countries measurements are routinely taken manually by scientists
in the field and there are indications this work has dropped off.
A huge
slump in air travel since the start of the pandemic has dented the collection
of ambient temperature and wind speed taken in-flight by sensors fitted to
commercial airliners through an initiative called the Aircraft Meteorological
Data Relay program. A coalition of national weather services across Europe are
discussing how to compensate for the decrease in the 700,000 climate
observations normally provided per day by aircraft.
In the US,
a swath of climate research work has been called off or delayed. Nasa-led
missions to survey the loss of land in the Mississippi River delta and
hurricane recovery in Puerto Rico have been suspended. With all flights to and
from Greenland suspended, a project to collect cores from the country’s vast
ice sheet has been voided for the year.
Nasa has
asked staff to work remotely where possible, with a spokesman telling the
Guardian that the agency has a continuity plan to ensure that there is “no
interruption of climate-relevant data”.
A five-year
Nasa project to study the impact of severe thunderstorms that enter the
stratosphere is now mired in uncertainty. Researchers from several universities
have partnered with Nasa to use its high-altitude ER-2 aircraft to take
measurements this summer but this work is now on hold.
“Because of
the delays we haven’t started tests yet and it’s not clear if we are going to
be able to do that,” said Kenneth Bowman, a climate scientist at Texas A&M
University, who is working on the project. “We don’t really know the timings,
we are taking it week to week. It’s always frustrating having all of your plans
disrupted, not knowing when we will do what we want to do.”
Bowman said
routine climate monitoring is “robust” and that he would be surprised if the
pandemic disrupted this work unless it spooled out for many months or years.
Gabriel
Vecchi, a climate modeler at Princeton University, said while he was concerned
about the impact of the pandemic on data collection he was “quite heartened”
that observations of the Earth’s surface have continued unabated so far.
“We should
all be grateful for the people and organizations that are continuing these
essential forecast and monitoring operations, in spite of the severe challenges
they are facing,” he said.
If the
pandemic lingers then climate scientists will face challenges shared by some
other professions – meetings of teams will have to be reorientated, the
maintenance of equipment will somehow have to be done and trips to research
sites will be curtailed.
This is
occurring at a time when air pollution, as well as planet-heating gases, has
declined considerably in China and Europe due to a reduction in human activity.
“For the
most part these polluted areas have snuck up on people and they have become the
norm and when the public realize it doesn’t have to be that way, I can imagine
considerable pressures to not let it go back to how it was,” said Kevin
Trenberth, a veteran climate scientist.
“I can
imagine that commuting from home may become a lot more common as we move ahead,
to the advantage of the climate system and fossil fuel use, and to everyone.”
