Global heating likely to hit world food supply before 1.5°C, says UN expert – “Climate change is a pandemic that we need to fight quickly. See how fast the degradation of the climate is going – I think it’s going even faster than we predicted.”

By Fiona Harvey 12 August 2023 (The Guardian) – The world is likely to face major disruption to food supplies well before temperatures rise by the 1.5C target, the president of the UN’s desertification conference has warned, as the impacts of the climate crisis combine with water scarcity and poor farming practices to threaten global […]

Climate collapse could happen fast – “Many scientists knew these things would happen, but we’re taken aback by the severity of the major changes we’re seeing”

By Lois Parshley 20 July 2023 (The Atlantic) – Ever since some of the earliest projections of climate change were made back in the 1970s, they have been remarkably accurate at predicting the rate at which global temperatures would rise. For decades, climate change has proceeded at roughly the expected pace, says David Armstrong McKay, a […]

Meridional winds in m/s (contours; purple: southerly, orange: northerly winds, in (a–c, e–g) contours start at an absolute value of 3 m/s and increase/decrease by 3 respectively, in (d, h) contours start an absolute value of 0.5 and increase/decrease by steps of one) and near surface temperature anomalies filled contours during (a–c) wave-7 and (e–g) wave- 5 events relative to the respective climatology in the northern hemisphere summer (JJA) based on (a, e) ERA5 reanalysis (1960–2014), (b, f) historical (1960–2014) and (c, g) future (SSP5-8.5, 2045–2099) bias-adjusted output from CMIP6 simulations (four models). d, h) Difference in meridional winds and temperature response during wave events comparing historical and future patterns in four bias-adjusted CMIP6 models (for twelve non adjusted models see Fig. S6). Hatching shows statistical significance on a 95% confidence level (a, d, e, h) or 100% model agreement in sign (4 out of 4 models, b, c, f, g) While the phase positions and intensity of the wave patterns (line contour) are well represented in the models their surface imprint are considerably underestimated in historical simulations. Changes in the temperature response are identified over North America, Eurasia and East Asia (d, h). Graphic: Kornhuber, et al., 2023 / Nature Communications

Study finds climate risk to crops greater than thought – Simultaneous harvest failures across major crop-producing regions threaten global food security – “These types of concurring events are really largely underestimated”

By Kelly Macnamara 4 July 2023 (AFP) – The risks of harvest failures in multiple global breadbaskets have been underestimated, according to a study Tuesday that researchers said should be a “wake up call” about the threat climate change poses to our food systems. Food production is both a key source of planet-warming emissions and […]

Drowned 16th-century church emerges from bottom of Mexico reservoir after drought – “What do I support my family with? Right now, I have nothing.”

By Aristos Georgiou 19 June 23 (Newsweek) – A 16th-century church has emerged from the waters of a reservoir in Mexico amid a drought. The colonial-era Dominican church is located in Quechula in the southern Mexican state of Chiapas. The building had been almost entirely submerged since 1966 when a dam was built on a […]

The human Ecological Footprint measured as “Overshoot Day”, 1971-2023. The Ecological Footprint is the most comprehensive biological resource accounting metric available. Based on 15,000 data points per country per year, it adds up all of people’s competing demands for biologically productive areas – food, timber, fibers, carbon sequestration, and accommodation of infrastructure. Currently, the carbon footprint, i.e., the carbon emissions from burning fossil fuel, make up 61 percent of humanity’s Ecological Footprint. For the last 5 years, the trend has flattened. How much of this is driven by economic slow-down or deliberate decarbonization efforts is difficult to discern. Still, overshoot reduction is far too slow. To reach the UN’s IPCC target of reducing carbon emissions by 43 percent worldwide by 2030 compared to 2010 would require moving Earth Overshoot Day 19 days annually for the next seven years.

The 2023 Earth Overshoot Day lands on August 2 – Trend is flattening but still far from reversing – “Persistent overshoot leads to ever more prominent symptoms including unusual heat waves, forest fires, droughts, and floods, with the risk of compromising food production”

GENEVA, SWITZERLAND, 5 June 2023 – August 2nd marks this year’s Earth Overshoot Day, according to the latest National Footprint and Biocapacity Accounts. They now track countries’ performance up to 2022, reducing reporting lag by three years. However, Earth Overshoot Day’s apparent delay by five days compared to last year’s isn’t all good news, as genuine advancements amount […]

Europe is struggling with a precarious water situation ahead of another drought-riven summer in 2023 – “A few years ago, I would never have imagined that water would be a problem here in Europe, especially in Germany or Austria”

By Sam Meredith 5 June 2023 (CNBC) – European policymakers are battling to get to grips with a growing water crisis ahead of what researchers fear could be yet another climate crisis-fueled summer of drought. Water resources in Europe are growing increasingly scarce because of the deepening climate emergency, with record-breaking temperatures through spring and a historic winter […]

Kansas wheat harvest in 2023 expected to be historically small due to two-year drought

By Morgan Mobley 5 June 2023 (KCTV) – Kansas has been called the country’s breadbasket. Now, wheat farmers in the state will reap their smallest harvest in more than 60 years. This will go directly down the chain, from farmers to consumers at the grocery store. Kansas flour mills will likely have to buy wheat […]

Southern China swelters, power grids struggle under “relentless” heatwaves – Pigs, rabbits, and fish dying from searing temperatures – “It’s just been week on week on week of these records being shattered”

By David Kirton 2 June 2023 BEIJING (Reuters) – Heatwaves tormenting parts of southern and eastern China are set to persist through June, putting power grids under strain as air conditioners are turned on full blast at homes, offices and factories in mega-cities like Shanghai and Shenzhen. In the next three days, most of southern […]

Satellite view of the Iberian Peninsula on 11 May 2023 and 11 May 2023. These images, acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, show where green vegetation in May 2022 turned brown by May 2023. The sparse rainfall further parched soils that were already unusually dry in 2022. According to a recent report by Copernicus Climate Change Services, soil moisture across all of Europe in 2022 was the second lowest in the past 50 years. Unseasonable heat exacerbated the prolonged drought. On 26 April 2023, hot air from North Africa swept over southern Spain and pushed the temperature at the Córdoba airport to 38.8°C (101.8°F), the highest April temperature recorded in continental Spain.

Drought in Spain spurs largest-ever claim for agricultural insurance – 2023 sees the highest number of fires and the most extensive burned area since 2006

By Akankshita Mukhopadhyay 26 May 2023 (Reinsurance News) – The drought in Spain would be the largest claim ever paid by the Spanish agricultural insurance, according to professional services firm Aon. Agroseguro, the leading agricultural insurance provider in Spain, is bracing for an unprecedented payout of over €300 million ($325 million) in compensations due to […]
