One-in-30-year heat-related mortality that is avoidable by stabilizing future warming at the 1.5° and 2°C Paris Agreement thresholds rather than 3°C. The point estimates show the mean 1-in-30-year mortality level across 101 plausible exposure-response relationships, whereas the error bars show the 95% eCI accounting for uncertainties from internal climate variability and the exposure-response relationship. All estimates assume constant population. Confidence intervals that do not include 0 (dotted line on each panel) indicate a statistically significant number of avoidable deaths. The size of each bubble on the central map is proportional to the square root of the city’s population in July 2016. The color of each bubble indicates the city’s projected population change between 2015 and 2040. Graphic: Lo, et al., 2019 / Science Advances

Adjusting carbon emissions to the Paris climate commitments would prevent thousands of heat-related deaths per city – “Compelling evidence for the heat-related health benefits of limiting global warming to 1.5°C”

5 June 2019 (University of Bristol) – Thousands of annual heat-related deaths could be potentially avoided in major US cities if global temperatures are limited to the Paris Climate Goals compared with current climate commitments, a new study led by the University of Bristol has found. The research, published today in the journal Science Advances, is […]

Spatial patterns of projected biomass changes. Shown are global ensemble projections at a 1 × 1 degree resolution for (A, C, and E) RCP2.6 and (B, D, and F) RCP8.5. (A and B) Multimodel mean change (percent, n = 10) in total marine animal biomass in 2090–2099 relative to 1990–1999 without fishing. (C and D) Variability among different ecosystem model and ESM combinations expressed as 1 SD. (E and F) Model agreement (percent) on the direction of change. Graphic: Lotze, et al., 2019 / PNAS

Study projects substantial declines in large fish and marine species with warming oceans – “There are substantial consequences for marine ecosystems on a global scale”

By Alison Auld 11 June 2019 (Dal News) – Populations of large fish and other marine species will decline steadily if little is done to stem the effects of climate change, according to a study led by Dalhousie University researchers that shows how greenhouse gas emissions could cause widespread global stock losses and habitat shifts. […]

Almost 600 plant species have already gone extinct – “Plant extinction is bad news for all species”

By Amanda Gonzalez Bengtsson 11 June 2019 (Stockholm University) – For the first time ever, scientists at the Royal Botanic Gardens, Kew and Stockholm University, have compiled a global analysis of all plant extinction records documented from across the world. This unique dataset published today in leading journal, Nature Ecology & Evolution, brings together data […]

Brazil guts environmental agencies, clears way for unchecked deforestation – “If before, staff were already being attacked by loggers, imagine what it is like with the president’s endorsement of the criminals”

By Sue Branford and Thais Borges 10 June 2019 (Mongabay) – The Brazilian government’s environmental agency, IBAMA, has so far this year imposed the lowest number of fines for illegal deforestation in at least 11 years, while the country’s other leading environmental agency and its federal parks’ protector, ICMBio (the Chico Mendes Institute), did not […]

BP Statistical Review of World Energy 2019: “A growing mismatch between hopes and reality”

By Spencer Dale 11 June 2019 (BP) – The Statistical Review of World Energy has been providing timely and objective energy data for the past 68 years. In addition to the raw data, the Statistical Review also provides a record of key energy developments and events through time. My guess is that when our successors […]

“Day Zero” in India looming for millions

By Dr. Jeff Masters 6 June 2019 (Weather Underground) – In early 2018, a three-year drought pushed Cape Town, South Africa, within weeks of experiencing “Day Zero”—the day when the city would run out of water and the taps be shut off. Fortunately, extreme water conservation efforts and the arrival of timely rains pushed “Day […]

Graph of the Day: Carbon emissions and human population, 1751-2018

9 June 2019 (Desdemona Despair) – It’s time to update one of Desdemona’s favorite graphs: human carbon emissions per capita. In the last update, four years ago, we had carbon emissions data through the year 2013, and it was clear that per-person emissions growth followed a nearly perfect exponential curve. The curve passed through one ton […]

It’s not your imagination: Allergy season gets worse every year – Pollen allergy seasons continue to get longer and more intense as temperatures rise

By Umair Irfan 21 May 2019 (Vox) – The weather is warming. The flowers are blooming. Noses are running. Eyes are watering. It’s allergy season, and this year it’s been severe in states like Georgia, and cities like Chicago, where the frigid winter delayed the onset. Now that it’s late May, we’re moving away from peak tree […]

Wettest 12 months in U.S. history, again – “The last twelve months beat the previous record, set just a month ago, by a full 1.48 inches”

By Bob Henson 6 June 2019 (Weather Underground) – Propelled by a two-week siege of widespread severe weather and heavy rain in late May, the contiguous U.S. has once again broken its record for the wettest year-long span in data going back to 1895. According to the monthly U.S. climate summary released Thursday from the […]

Abnormal high temperatures in Alaska disrupt isolated communities, upset subsistence hunting patterns, and cause deaths – “It’s hard to characterize this anomaly, it’s just pretty darn remarkable for that part of the world”

By Tim Lydon 29 May 2019 (Hakai Magazine) – Alaska in March is supposed to be cold. Along the north and west coasts, the ocean should be frozen farther than the eye can see. In the state’s interior, rivers should be locked in ice so thick that they double as roads for snowmobiles and trucks. […]
