On May 16 James Hansen and his colleagues said the following: "Global temperature is likely to continue to rise a bit for at least a month, peak this summer, and then decline as the El Nino fades toward La Nina. "Present extreme planetary energy imbalance will limit La Nina-driven temperature...

May temperature projection
With half the month of data in, its very likely (>95% chance) that May 2024 will be the warmest May on record, extending the streak of record breaking months to 12 in a row: [image or embed] — Zeke Hausfather (@hausfath.bsky.social) May 15, 2024 at 20:32 Reminder from January 12, 2024 by...
April data
The Climate Change Services team have just published the ERA5 April analysis. High level: The team that manages the ERA5 climate dataset have just released their April analysis. High level: April was the hottest April in recorded history at +1.58°C above the 1850-1900 average The 12-month running...
Another milestone passed
On January 12, 2024 Hansen et al made this prediction: We expect record monthly temperatures to continue into mid-2024 due to the present large planetary energy imbalance, with the 12-month running-mean global temperature reaching +1.6-1.7°C relative to 1880-1920 and falling to only +1.4 ± 0.1°C...
We can’t avoid the 1.5°C reality anymore
Mainstream climate scientists are finally joining what was considered a fringe group not so long ago and admitting that we have lost the ability to keep warming below 1.5°C The rapidly shrinking carbon budget As mentioned before on this blog we must now prepare to live in a 1.5°C world. There has...
The ocean – Jan 2024
Pay attention to the instrument data this tells us exactly what’s coming. Remember there is generally a delay between observed data readings and the impacts thereof. 2024 starts with sea surface temperatures *above* where they were at the start of 2023 (orange line) and above the record set in...
The instruments are all flashing red
The instruments are all flashing red: Carbon atmospheric concentrations currently at 424 ppm Methane atmospheric concentrations currently at 1919.97 ppb Heating above preindustrial average currently at +1.27°C Ocean temperatures currently +20.9°C (60S-60N) Our response to all these records? >...
Record keeping
These 291 weather stations have been collecting a wide range of weather data, including temperature, precipitation, humidity, wind speed and direction, and solar radiation for at least 100 years. The commitment to keep these running form the backbone of our monitoring climate change. This data was...
Trust the instruments
Our instruments are getting smarter and smarter and their data more and more accurate. We ignore their data at our own peril. For example here are what satellites can tell us about our changing climate: Greenhouse Gases Satellites measure the global concentrations of atmospheric CO2 and methane,...
We are edging closer
Copernicus ECMWF data for March 2023. One month does not a trend make however we are moving ever closer to being permanently above the 1.5° mark. March 2023, now joins the Marches of 2016 (hottest year on record), 2017, 2019 and 2020 all of which were above 1.5° The projection for the year is that...
