In a Landmark Study, #Scientists Discover Just How Much #Earth’s Temperature Has Changed Over Nearly 500 Million Years

Researchers show the average #surfacetemperature on our #planet has shifted between 51.8 to 96.8 degrees Fahrenheit

Does anyone know if there is historical temperature comparison data anywhere for the Greek islands?

Climate stripes exist for "all of Greece" and "Athens", but not for any of the larger islands. Everything else I can find is just "this is what the climate is like there" info for tourists, without a temporal axis.

I would ideally like to compare Rhodes in the 80s to today, or the last decade.

graphic - stylised schematic - atmospheric river from space

maps and charts - (a) Atmospheric river (AR) characteristics, including duration, interval, area, and intensity during the DJF globally. The central plot displays the increase in AR frequency between the far-future (SSP585; 2070–2099) and the historical (1980–2009) periods, with the climatological AR frequency in the historical period represented by the contours. Black dots indicate unanimous frequency changes among CMIP6 models. The red rectangles are the boundaries of the target regions and the black hatches are the selected land regions. The surrounding plots show 2D Kernel Density Estimation (KDE) maps for AR characteristics over the historical period and far-future under different scenarios displayed in the bottom right corner for eight regions. The univariate distributions of the characteristics are shown on the outer axes of each subplot. (b) The comparison of the KDE maps for three selected regions with ARs detected with GuanWaliser_v2 and Mundhenk_v3 AR detection tools (ARDTs). Note that only the SSP585 scenario is available for the far-future period in these two data sets. The legend is the same as in Panel (a). Note that the figures of PanLu ARDT are presented based on daily scale data sets, while the figures of GuanWaliser_v2 and Mundhenk_v3 ARDTs are presented on 6-hourly scale data sets due to data accessibility.

"Record shattering: #Earth had its #hottest #July in 174 years -
Global sea surface temperature hit record high for 4th-consecutive month

Earth just roasted under its hottest July on record, according to scientists from NOAA’s National Centers for Environmental Information (NCEI). For the fourth-consecutive month, the global ocean surface temperature also hit a record high.

#Climate by the numbers - July 2023 - The average global surface temperature in July was 2.02 degrees F (1.12 degrees C) above average, ranking it as the warmest July in NOAA’s 174-year record. Because July is the globe’s warmest month of the year from a climatological perspective, July 2023 was also likely Earth’s warmest month on record.

July 2023 was the first time an average July temperature exceeded 1.8 degrees F (1.0 degree C) above the long-term average. Also of note, last month was 0.36 of a degree F (0.20 of a degree C) warmer than the previous July record from 2021. July 2023 marked the 47th-consecutive July and the 533rd-consecutive month with temperatures above the 20th-century average.

For the fourth-consecutive month, the global ocean surface temperature hit a record high as El Niño conditions that emerged in June continued into July. Globally, July 2023 set a record for the highest monthly sea surface temperature anomaly — which indicates how much warmer or cooler temperatures are from the long-term average — of any month in NOAA’s climate record, with an anomaly of 1.78 degrees F or 0.99 of a degree C. On July 13, NOAA’s Climate Prediction Center issued a statement announcing a greater than 95% chance that El Nino will continue through winter in the Northern Hemisphere.
