NASA is hoping that nations will work together more closely in the future on topics such as climate change, including greenhouse gas emissions, the space agency’s head, Bill Nelson, said on Tuesday.
Solutions to mitigate greenhouse gas emissions that rapidly warm the planet and drive the climate crisis already exist, but require unprecedented changes at a new scale and pace.
“This is something that nations can work on together because the information is there,” Nelson said in Mexico City when asked about how to address greenhouse gas emissions. “It’s important that we act on it.”
Satellites have emerged as powerful tools for scientists around the world to study climate change but also, increasingly, pinpoint the origin of greenhouse gas emissions, such as methane leaks, that would otherwise have gone undetected.
Nelson added that satellites were constantly collecting data about climate and NASA was looking to make this data accessible, and educate people on how to use it.
Methane, the main component of natural gas, is the second-largest contributor to global warming after carbon dioxide. Scientists can now pinpoint the origin of large methane leaks using data gathered by satellites.
It is a much more potent driver of global warming in the short term than carbon dioxide because it traps more heat in the atmosphere, ton for ton.
“The types of concerns that we have are global,” said NASA Deputy Administrator Pam Melroy. “It’s very important to recognize that not any one country can solve that problem alone.”
Earlier in the day, Nelson and Melroy, who are both astronauts, met with Mexican President Andres Manuel Lopez Obrador and lawmakers to discuss how the countries can work together.
Earlier, The UN weather agency is sounding a “red alert” about global warming, citing record-smashing increases last year in greenhouse gases, land and water temperatures and melting of glaciers and sea ice, and warning that the world’s efforts to reverse the trend have been inadequate.
The World Meteorological Organization, in a “State of the Global Climate” report released Tuesday, ratcheted up concerns that a much-vaunted climate goal is increasingly in jeopardy: That the world can unite to limit planetary warming to no more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) from pre-industrial levels.
“Never have we been so close – albeit on a temporary basis at the moment – to the 1.5° C lower limit of the Paris agreement on climate change,” said Celeste Saulo, the agency’s secretary-general. “The WMO community is sounding the red alert to the world.”
The 12-month period from March 2023 to February 2024 pushed beyond that 1.5-degree limit, averaging 1.56 C (2.81 F) higher, according to the European Union’s Copernicus Climate Service. It said the calendar year 2023 was just below 1.5 C at 1.48 C (2.66 F), but a record hot start to this year pushed beyond that level for the 12-month average.
“Earth’s issuing a distress call,” UN Secretary-General Antonio Guterres said. “The latest State of the Global Climate report shows a planet on the brink. Fossil fuel pollution is sending climate chaos off the charts.”
The latest WMO findings are especially stark when compiled in a single report. In 2023, over 90 percent of ocean waters experienced heat wave conditions at least once. Glaciers monitored since 1950 lost the most ice on record. Antarctic sea ice retreated to its lowest level ever.
