Hottest Year on Record In India:
They are 2016, 2023, 2009, 2017 and 2010 (in descending order). New Delhi: The year 2023 ended as the second warmest on record for India since 1901, the India Meteorological Department said on Monday, noting that months of August and February were the warmest in the last 123 years.
March: The average maximum temperature of 33.10 degrees Celsius recorded in March 2022 is the highest ever in last 122 years, according a statement on Saturday by the India Meteorological Department. In March 2010, the country had recorded a maximum temperature of 33.09 degrees Celsius.
The IMD said the average maximum, minimum and mean temperatures for the country as a whole last month were 33.10 degrees C, 20.24 degrees C and 26.67 degrees C respectively, against the normal of 31.24 degrees C, 18.87 degrees C and 25.06 degrees C, respectively, based on the period 1981-2010. The country’s average mean temperature of 26.67 degrees C in March was the second highest after 26.671 degrees C recorded in March 2010.
The weather office attributed the unusually hot month to the absence of active western disturbance over north India and of any major easterly system over south India, causing subdued rainfall and very less thunderstorm activities over most parts of the country.
The rainfall recorded last month in the country as a whole was 8.9 mm, which was 71 per cent less than its long period average rainfall of 30.4 mm.
The countrywide average minimum temperature of 20.24 degrees Celsius in March this year was the third highest in 122 years.
Climate Change and Warning Models and Observations...By Roy Spencer PhD...Climatologist, Former NASA Scientist
The most important thing to remember about climate models which are used to project future global warming is that they were “tuned” with the assumption I started this article with: that the climate system is in a natural state of energy balance, and that there is no long-term climate change unless humans cause it.
This is an arbitrary and illogical assumption. The climate system is an example of a “nonlinear dynamical system”, which means it can change all by itself. For example, slow changes in the rate of vertical overturning of the world’s oceans can cause global warming (or global cooling) with no “external forcing” of the climate system whatsoever.
Instead, the climate models are “tuned” to not produce natural climate change. If a 100-year run of the model produces change, the model is adjusted to removed the “drift”. The models do not produce global energy balance from “first physical principles”, because none of the processes controlling that balance are known to sufficient accuracy. Instead, the models are “fudged” to produce energy balance, based upon the modelers’ assumption of no natural climate change. Then, the models are used as “proof” that only increasing CO2 has caused recent warming.
This is circular reasoning.
I am not against modeling; models are necessary to understand complex processes in the climate system. But, while the models are useful and necessary tools for studying climate change, I do not think they can yet be relied upon for major changes in energy policy.
Believe it or not, very little research has ever been funded to search for natural mechanisms of warming…it has simply been assumed that global warming is manmade. This assumption is rather easy for scientists since we do not have enough accurate global data for a long enough period of time to see whether there are natural warming mechanisms at work.
It is simply what the climate system does. This is actually quite easy for meteorologists to believe, since we understand how complex weather processes are.

all this teeth gnashing over what models should be included just shows now unready for primetime the state of the models are.
projections need to be keyed to observations and far from it is that recommendation only coming from roy. dr curry and others have been calling for that for years.
its obvious that our policies should follow from real observations and not projections that nobody is in agreement with.
U.S.A. Temperature Trends, 1979-2023: Models vs. Observations
February 2nd, 2024 by Roy W. Spencer, Ph. D.
Updated through 2023, here is a comparison of the “USA48” annual surface air temperature trend as computed by NOAA (+0.27 deg. C/decade, blue bar) to those in the CMIP6 climate models for the same time period and region (red bars). Following Gavin Schmidt’s concern that not all CMIP6 models should be included in such comparisons, I am only including those models having equilibrium climate sensitivities in the IPCC’s “highly likely” range of 2 to 5 deg. C for a doubling of atmospheric CO2.
Approximately 6 times as many models (23) have more warming than the NOAA observations than those having cooler trends (4). The model trends average 42% warmer than the observed temperature trends. As I allude to in the graph, there is evidence that the NOAA thermometer-based observations have a warm bias due to little-to-no adjustment for the Urban Heat Island effect, but our latest estimate of that bias (now in review at Journal of Applied Meteorology and Climatology) suggests the UHI effect in the U.S. has been rather small since about 1960.
Note I have also included our UAH lower tropospheric trend, even though I do not expect as good agreement between tropospheric and surface temperature trends in a regional area like the U.S. as for global, hemispheric, or tropical average trends. Theoretically, the tropospheric warming should be a little stronger than surface warming, but that depends upon how much positive water vapor feedback actually exists in nature (It is certainly positive in the atmospheric boundary layer where surface evaporation dominates, but it’s not obviously positive in the free-troposphere where precipitation efficiency changes with warming are largely unknown. I believe this is why there is little to no observational evidence of a tropical “hot spot” as predicted by models).
now switch to a comparison for just the summer months (June, July, August), the discrepancy between climate model and observed warming trends is larger, with the model trends averaging 59% warmer than the observations:
Now switch to a comparison for just the summer months (June, July, August), the discrepancy between climate model and observed warming trends is larger, with the model trends averaging 59% warmer than the observations:
For the summer season, there are 26 models exhibiting warmer trends than the observations, and only 1 model with a weaker warming trend. The satellite tropospheric temperature trend is weakest of all.
Given that “global warming” is a greater concern in the summer, these results further demonstrate that the climate models depended upon for public policy should not be believed when it comes to their global warming projections.

From ToI
1892 year, a year which will be remembered as very dry and hot winters, very dry and hot summers but good monsoon especially in last 2 months of monsoon. Temperature in all winter and summer months were excessively above normal just opposite of its last year 1891 when temperatures were excessively below normal in its winter and summer months. Below image shown are temperature data of various parts of India of January and Feb month (All data is in Fahrenheit. To convert it into Celsius just divide it by 1.8)
Below attached image shows temperature data of March,April,May month of various parts of India. You can see how high the temperature were in 1st 5 months of the year especially in upper and western parts of India. (All data in Fahrenheit to convert it into Celsius just divide it by 1.8)
Temperature in March month itself become so high that it already touched to 43-46c range in most parts of N, W and central parts of India shattering many past records.
Deesa(Gujarat) 46c shattering 43c record of March 1880
Pachpadra (Rajputana) 45c shattering 44c record of March 1880
Sirsa (Rajasthan) 44c shattering 39c record of March 1880
Nagpur 45c shattering 43c record of March 1880
Rajkot 44c shattering 43c record of March 1880
Indore 41c shattering 40c record of March 1880.
Jacodabad 44c shattering 43c record of March 1880
Same record breaking heat continues even in April shattering many past records
Deesa 46c shattering 44c record of April 1880
Dera Ismail khan 45c shattering 44c record of April 1880
Nagpur 46c shattering 45c record of April 1879
Sholapur 44c shattering 43.7c record of April 1881
Rajamundhry(Madras) 44.5c shattering 43c record of April 1888
Jacodabad 47c shattering 46c record of April 1880.
In last week of April a small cyclonic storm of considerable intensity formed in Arabian sea and has made landfall over kathiawar (Sauarshtra) just to the west of Mandvi on May 1. The average velocity of wind between 10 am to 1:30 pm in Bhuj almost exceeded 100 miles per hour (161 km/h) causing the massive damage. In whole of Kutch 38 persons were killed while 141 people were wounded. About 98,000 houses were damaged, 30 boats were destroyed. About 1,26,000 trees were uprooted and 5,00,000 trees were much injured.
After first week of May temperature started rising considerably with some stations again breaking the past records while many other stations near to breaking its past records
Rajamundhry (Madras) 47c on 14th May shattering 46c record of May 1887
Cuddapah (Deccan) 45c on 14th and 16th May shattering 44c record of May 1886
Jacodabad 49.4c. Earlier record 50.5c of May 1888
Lahore 48c. Earlier record 49c of May 1879
Bikaner 45c on 21st and 31st May
Jeypore(Rajputana) 45c on 21st
Deesa 43c. Earlier record 47.4c of May 1881
In June month monsoon remained very poor especially the Arabian sea branch and so temperature remained above normal in most parts of upper and western India
(Data given here is in Fahrenheit. To convert it into Celsius just divide it by 1.8.) So straight 6th month temperature remained above normal for upper and western India. Except deccan plateau and Madras whole India received scanty rain
It seems summers is in no mood to leave India as straight 7th month India was under the grip of deadly heat shattering many past records due to massive failure of monsoon.
Dera Ismail khan 49c (10c above normal) shattering 47.5c record of July 1888
Lahore 47.3c.(9c above normal) Record not broken (47.5c in July 1878)
Peshawar 47c shattering 46c record of July 1887
Jacodabad 47c. Record not broken (48.6c in July 1878)
Agra 46c(12.5c above normal) shattering 44c record of July 1868
From the last week of July finally monsoon currents became strong and gave bountiful rain in almost all parts of India which continued even in August month
Rainfall was largely in excess in all parts of India in August month as can be seen in above image giving much relief from prolonged heat waves. Many flood events occurred in Punjab and Sindh in August month. Nothing remarkable happened in September and October month.
North East monsoon which gives rainfall to South east coast in November and December month completely failed.
As you can see whole SE coast of India were largely in deficit. Even in December month north east monsoon failed considerably.
Here is the list below for decade avg:
