Wrong again. This graph is clearly a very crude approximate of past data. When you look at other temperature record graphs, they show just as crazy spikes in the past as we've had now.

BTW, since most of the CO2 has been emitted post 1950, you should be able to show accelerated warming in at least one place on earth since then. Here are three graphs I've posted before. Does that look like acceleration to you?

New heated airport runway concept may sharply bias ‘global warming’ signal in the global climate monitoring network
Anthony Watts / 2 hours ago February 23, 2018


Recent winter-weather related airport delays have become something that airport managers and airline executive want to solve. This story from NBC’s today show back in January 2018 highlights the issue and a potential solution:

Could heated airport runways melt away your winter travel headaches?

There have been thousands of flight delays and cancellations due to winter weather this year, and it’s only January. Not only that: snow and ice at airports can send planes skidding off slippery runways.

What if there were something that could fix all that? At Des Moines International Airport in Iowa, TODAY national investigative correspondent Jeff Rossen got a look at a new technology in action: heated runways and tarmacs.

Global climate is changing and this is apparent across the United States in a wide range of observations. The global warming of the past 50 years is primarily due to human activities, predominantly the burning of fossil fuels.
Some extreme weather and climate events have increased in recent decades, and new and stronger evidence confirms that some of these increases are related to human activities.
Human-induced climate change is projected to continue, and it will accelerate significantly if global emissions of heat-trapping gases continue to increase.
Impacts related to climate change are already evident in many sectors and are expected to become increasingly disruptive across the nation throughout this century and beyond.
Climate change threatens human health and well-being in many ways, including through more extreme weather events and wildfire, decreased air quality, and diseases transmitted by insects, food, and water.
Infrastructure is being damaged by sea level rise, heavy downpours, and extreme heat; damages are projected to increase with continued climate change.
Water quality and water supply reliability are jeopardized by climate change in a variety of ways that affect ecosystems and livelihoods.
Climate disruptions to agriculture have been increasing and are projected to become more severe over this century.
Climate change poses particular threats to Indigenous Peoples’ health, wellbeing, and ways of life.
Ecosystems and the benefits they provide to society are being affected by climate change. The capacity of ecosystems to buffer the impacts of extreme events like fires, floods, and severe storms is being overwhelmed.
Ocean waters are becoming warmer and more acidic, broadly affecting ocean circulation, chemistry, ecosystems, and marine life.
Planning for adaptation (to address and prepare for impacts) and mitigation (to reduce future climate change, for example by cutting emissions) is becoming more widespread, but current implementation efforts are insufficient to avoid increasingly negative social, environmental, and economic consequences.

Both NOAA and NASA stand by the data sets they produce through observation and computer models. Humans are having a hand in the change and it is taking place at a faster rate than otherwise it would left to nature.

Google is your friend. I suggest you use it. How else are you supposed to find temperature graphs? https://en.wikipedia.org/wiki/Global_temperature_record

Yup, and all that apparent extra heat is a good thing...

Visited many airports in Canada I have never seen the AWOS that close to the runway, The picture of the Des Moines airport is strange because different aspects of the reported weather data could also be affected by aircraft taxing by that point.

There are ICAO and WMO standards for where the weather reporting equipment can be located. There is also additional equipment which is located near the runway for aviation purposes, such as RVR and wind speed/direction equipment, but temperature and other reporting equipment are not located near the runway.

I have some experience in this area, and have been part of teams that were responsible for the location of weather reporting equipment on airports.

The Arctic is still mostly in the darkness of winter right now, but you wouldn't know it from the weather, as temperatures have skyrocketed across most of the region, and may go even higher in the days to come.

In a little over a week, temperatures north of Greenland, and towards the North Pole, have jumped by 20 to 30 oC, putting some areas above the freezing mark, even whilehttps://www.theweathernetwork.com/ ... ead/96258/ they're still in the darkest depths of winter.

It's quite normal for arctic temperatures to jump 30 degrees. Heck, even around here it does that in the winter. In fact, two weeks ago it, it did that in one day.

You posted some Noaa graphs out of context to prove a false point and then when confronted with the real data your reply is that?

Both Noaa and Nasa supply peer reviewed data sets . They both say that the rate of warming is happening at a,quicker rate than what should be happening naturaly .


Either post peer reviewed data sets saying otherwise or not .graphs taken out. Of context prove nothing but creative editing

That’s funny. Reminds me of the Bill Nye and Al Gore climate 101 video in which they used photoshop to fake the thermometer reading. In their video, CO2 doesn’t behave as they believe it should, so they fake the results.

This is where the wind and temperature sensors are located at Penticton. Top right corner of image. Not sure about Kelowna but I do know it's on the east side as well, near the control tower. That one is a full AWOS that also has visibility, cloud height and precipitation sensors.

According to NOAA:

“Temperature sensor siting: The sensor should be mounted 5 feet +/- 1 foot above the ground. The ground over which the shelter [radiation] is located should be typical of the surrounding area. A level, open clearing is desirable so the thermometers are freely ventilated by air flow. Do not install the sensor on a steep slope or in a sheltered hollow unless it is typical of the area or unless data from that type of site are desired. When possible, the shelter should be no closer than four times the height of any obstruction (tree, fence, building, etc.). The sensor should be at least 100 feet from any paved or concrete surface.” Not sure, but that didn’t quite look like 100’. Such rules are broken in many sites and do account for temperature rise.

We’ve all seen this photo. It barely scrapes the surface.

Hadn't seen that, so thought others may be interested to know more about it, too. Did an image search to find out where it's located.
This one takes the cake, and I think it is worse than our former worst-case USHCN station (now closed) located in a parking lot in Tucson at the University of Arizona

Found that and quite a lot of interesting stuff on this subject here:
