They decided to provide public monthly climate updates after NOAA, citing Trump administration budget cuts, canceled its briefings last year. Climate Central\u2019s monthly briefings are part of <a href=\"https:\/\/insideclimatenews.org\/news\/01102025\/climate-science-available-online\/\" rel=\"nofollow noopener\" target=\"_blank\">a larger effort<\/a> to ensure useful climate information remains available to the public as the current administration tries to erase the topic from government records.<\/p>\n<p class=\"wp-block-paragraph\">Several other research groups, including <a href=\"https:\/\/berkeleyearth.org\/\" rel=\"nofollow noopener\" target=\"_blank\">Berkeley Earth<\/a> and <a href=\"https:\/\/climate.copernicus.eu\/surging-tropical-pacific-ocean-surface-temperatures-and-early-european-heatwave-may\" rel=\"nofollow noopener\" target=\"_blank\">Copernicus<\/a>, the European Union\u2019s climate change service, also provide monthly public climate updates with data collected from global climate monitoring networks.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">\u201cWe heard from a lot of folks that they missed the NOAA briefings and being able to talk with experts,\u201d said Climate Central\u2019s Tom Di Liberto. \u201cWe were happy to tap into Climate Central\u2019s expertise and combine it with our NOAA experience to bring this to fruition.\u201d He added that Labe leads the monthly briefing and aims to establish the links between human-caused warming and climate extremes.<\/p>\n<p class=\"wp-block-paragraph\">\u201cAs someone who used to be the climate scientist and meteorologist for climate.gov, and an expert guest on the old NOAA monthly climate briefings,\u201d Di Liberto said, \u201cthere certainly is more flexibility and freedom to make those connections front and center.\u201d<\/p>\n<p class=\"wp-block-paragraph\">During the briefing, Labe explained that atmospheric CO2 levels reach a seasonal peak each May, just before forests across the vast Northern Hemisphere landmasses go into full growth mode when they suck CO2 out of the air for several months.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">But human emissions are overwhelming forests, as well as the oceans, the other major natural carbon sponge, leading to continued buildup in the atmosphere and more heating. About two-thirds of the excess CO2 has accumulated just in the past 50 years.<\/p>\n<p class=\"wp-block-paragraph\">Separately from the Climate Central briefing, former NASA climate scientist <a href=\"https:\/\/bsky.app\/profile\/drjamesehansen.bsky.social\" rel=\"nofollow noopener\" target=\"_blank\">James Hansen<\/a> also reinforced his warning about a short-term temperature spike. In an <a href=\"https:\/\/www.columbia.edu\/~jeh1\/mailings\/2026\/2026GlobalTemperature.2026.06.12.pdf\" rel=\"nofollow noopener\" target=\"_blank\">update on his website<\/a> on Friday, Hansen wrote that many scientists are still underestimating how sensitive Earth\u2019s climate system is to greenhouse gases, and that 2026 is likely to be the planet\u2019s warmest year on record, despite starting out cooler than 2024, the previous record-warm year.<\/p>\n<p class=\"wp-block-paragraph\">Hansen wrote that he is concerned that the public does not understand the current dangerous acceleration of warming because \u201cthe media are gobbling up and regurgitating an interpretation of global climate change that we believe is fundamentally flawed,\u201d referring to what he says is the still-widely misunderstood overall sensitivity of the climate system, based on the estimates by the Intergovernmental Panel on Climate Change.<\/p>\n<p class=\"wp-block-paragraph\">On June 11, Copernicus also issued a dire warning about warming, with data showing that Earth\u2019s climate system is accumulating heat faster than at any time in the known record. The finding came in a major <a href=\"https:\/\/essd.copernicus.org\/articles\/18\/3889\/2026\/\" rel=\"nofollow noopener\" target=\"_blank\">report<\/a> written by 70 scientists from 56 institutions across 17 countries.<\/p>\n<p class=\"wp-block-paragraph\">The study shows \u201cnearly all of the warming over the last decade is driven by human activities,\u201d said <a href=\"https:\/\/www.ecmwf.int\/en\/about\/who-we-are\/staff-profiles\/samantha-burgess\" rel=\"nofollow noopener\" target=\"_blank\">Samantha Burgess<\/a>, the Copernicus strategic lead for climate.<\/p>\n<p class=\"wp-block-paragraph\">That \u201cenergy imbalance\u201d is a key indicator of the climate system, said climate scientist and lead author <a href=\"https:\/\/scholar.google.com\/citations?user=5uvTUloAAAAJ&amp;hl=en\" rel=\"nofollow noopener\" target=\"_blank\">Piers Forster<\/a>, director of the Priestley Centre for Climate Futures at the University of Leeds in the United Kingdom.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">\u201cIt provides a crucial measure of the pace of climate change,\u201d he said. \u201cWithout human influence, it should be close to zero \u2026 but it has doubled in recent decades.\u201d\u00a0<\/p>\n<p>\t\t\t\t\tAbout This Story<\/p>\n<p>Perhaps you noticed: This story, like all the news we publish, is free to read.
