High temperatures persist The image below, created with NASA data while using a 1903-1924 custom base, illustrates that the temperature anomaly through July 2024 has been more than 1.5°C above this base for each of the past consecutive 13 months, and even more when compared to a pre-industrial base. The red line shows the trend (one-year Lowess … Read more
Temperatures are forecast to reach 46.5°C or 115.8°F in Saudi Arabia (green circle left) and to reach 36.1°C or 96.9°F in China (green circle right) on August 4, 2024 06 UTC. As illustrated by the image below, ‘feels like’ temperatures are forecast to reach 42.1°C or 107.9°F in Saudi Arabia (green circle left) and 53.6°C … Read more
Large pieces of sea ice are breaking away from the northern tip of Greenland, to be carried by ocean currents to the Fram Strait east of Greenland. On their way they will melt away, illustrating how ocean heat can make even the thickest parts of the sea ice disappear in a matter of days. The … Read more
Wet Bulb Globe Temperature (WBGT) takes into account the effect of temperature, RH (relative humidity), wind speed, and solar radiation. WBGT is used by weather.gov to warn about extreme heat stress when in direct sunlight, as is forecast to occur in grey areas on July 26, 2024 at 21 UTC. [ click on images to … Read more
Temperatures are rising The NASA temperature anomaly vs. 1904-1924 shows that the temperature has been above 1.5°C for the past twelve months, as illustrated by the image below. The red line shows the trend (one-year Lowess Smoothing) associated with the rapid recent rise. Note that the 1904-1924 base is not pre-industrial. When using a genuinely … Read more
by Andrew Glikson Figure 1. 2023 was the Earth’s warmest year since modern record-keeping began in 1880. As temperatures in large parts of the Earth are soaring (cf. 52.3°C in Delhi, flames engulf large regions in California, tornadoes ravage the Gulf of Mexico states, severe drought starve populations in southern Africa and climate extremes continue … Read more
Global temperature [ from earlier post ] The above image, from an earlier post, shows that the February 2024 temperature was 1.76°C above 1885-1915, potentially 2.75°C above pre-industrial (bright yellow inset right). The image was created by Sam Carana for Arctic-news.blogspot.com with an April 2024 data.giss.nasa.gov screenshot. The red line (6 months Lowess smoothing) highlights … Read more
The above image shows a trend (magenta), based on NOAA August 2008 through June 2024 data (black) and added on a canvas that is 31.42-year wide. If this trend continues, the clouds tipping point could get crossed in early 2036 due to the rise in carbon dioxide (CO₂) alone. [ from earlier post ] Rising CO₂ emissions … Read more
Water vapor feedback There are numerous self-amplifying feedbacks that accelerate the temperature rise. One of them is the water vapor feedback. Just the temperature rise itself will cause more water vapor to be in the atmosphere. [ from Moistening Atmosphere ] The February 2024 temperature was 1.76°C above 1885-1915, which could be as much as 2.75°C above … Read more
This story was originally published by Yale Environment 360. After a decade of declining to finance large hydroelectric dams, the World Bank is getting back into the business in a big way. Throughout the last half of the 20th century, the bank was the world’s leading supporter of big hydro. But over the last two decades, it followed a zigzag pattern … Read more
