Temperature data from four international science institutions. All show rapid warming in the past few decades and that the last decade has been the hottest on record.

Temperature data showing rapid warming in the past few decades, the latest data going up to 2021. According to NASA data, 2016 and 2020 tied for the warmest year since 1880, continuing a long-term trend of rising global temperatures. The 15 warmest years on record have occurred since 2005, with the eight most recent years being the warmest. Credit: NASA's Goddard Institute for Space Studies
 
It’s important to remember that scientists always focus on the evidence, not on opinions. Scientific evidence continues to show that human activities (primarily the human burning of fossil fuels) have warmed Earth’s surface and its ocean basins, which in turn have continued to impact Earth’s climate. This is based on over a century of scientific evidence forming the structural backbone of today's civilization.

NASA Global Climate Change presents the state of scientific knowledge about climate change while highlighting the role NASA plays in better understanding our home planet. This effort includes citing multiple peer-reviewed studies from research groups across the world,1 illustrating the accuracy and consensus of research results (in this case, the scientific consensus on climate change) consistent with NASA’s scientific research portfolio.

With that said, multiple studies published in peer-reviewed scientific journals1show that climate-warming trends over the past century are extremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.

 

International Academies: Joint Statement​

"Climate change is real. There will always be uncertainty in understanding a system as complex as the world’s climate. However there is now strong evidence that significant global warming is occurring. The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and from phenomena such as increases in average global sea levels, retreating glaciers, and changes to many physical and biological systems. It is likely that most of the warming in recent decades can be attributed to human activities (IPCC 2001)." (2005, 11 international science academies)10

Statement on Climate Change from 18 Scientific Associations​

"Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver." (2009)2

Yes, observed temperature reading will continue to rise for decades more, as long as the global meteorological network is withing range of the urban heat island effect. We have no way of accurately removing the urban heat island effect from the observed reading, so we really have no accurate idea what the temperatures really are.

This is no surprise what so ever.

Repetitive talking point.

“Scientists have been very careful to ensure that UHI is not influencing the temperature trends. To address this concern, they have compared the data from remote stations (sites that are nowhere near human activity) to more urban sites. Likewise, investigators have also looked at sites across rural and urban China, which has experienced rapid growth in urbanisation over the past 30 years and is therefore very likely to show UHI. The difference between ideal rural sites compared to urban sites in temperature trends has been very small:

Li et al (solid green and brown) is an adjusted dataset of 42 rural and 40 urban sites. Li (blue) is a non-adjusted set of 728 stations, urban and rural. CRUTEM3v (red) is a land-only data set (Brohan et al., 2006). This plot uses the 1954–83 base period.”

Nobody disagrees with this. Only the quantification of this effect.

How many times a year are you going to post this?

The first "naysayer" shows up...
 
What's your problem with scientific facts?

None at all. Exactly what “scientific fact” did you post. Not your biased opinion, actual scientific fact.

“Jacobson and Ten Hoeve are authors of a paper describing the research that will be published in Journal of Climate. The paper is available online now. The study modeled climate response from 2005 to 2025.

Some global warming skeptics have claimed that the urban heat island effect is so strong that it has been skewing temperature measurements that show that global warming is happening. They have argued that urban areas are a larger contributor to global warming than the greenhouse gases produced by human activity, and thus drastic measures to reduce greenhouse gases are not needed.

"This study shows that the urban heat island effect is a relatively minor contributor to warming, contrary to what climate skeptics have claimed," Jacobson said. "Greenhouse gases and particulate black carbon cause far more warming."

“The U.S. Historical Climatology Network (USHCN) data are used to quantify national- and regional-scale temperature changes in the contiguous United States (CONUS). The USHCN is a designated subset of the NOAA Cooperative Observer Program (COOP) Network with sites selected according to their spatial coverage, record length, data completeness, and historical stability.
Hausfather and colleagues found that "urbanization accounts for 14% to 21% of the rise in unadjusted minimum temperatures since 1895 and 6% to 9% since 1960." However, the paper goes on to say that correction procedures have effectively removed the urban heat signal such that it has not caused a bias in temperature assessment over the past 50-80 years.”

 
Did you ignore this part of my post?

You don’t know that.
We have discussed this before, and nobody has shown the methodology/model is accurate. It's just one huge SWAG (scientific wild ass guess.) Comparing urban and rural stations is a joke. It in no way accurately shows a correct adjustment to use.

Can you supply us with a paper that shows it's accurate?

Your post is every bit as much garbage as those of flogger and Queen Margo. They ask questions, not for discussion, but for the sole purpose of criticizing the answer, no matter what it is, and neither of them know squat about the issue. Your first paragraph is what is SWAG. It’s just a claim without merit. And your use of the word “accurate” is garbage because no matter what anyone would say about it, you would simply repeat your first paragraph, just like flogger and Queen Margo repeat their garbage questions. Garbage in, garbage out, should be your motto.

Maybe if you guys would stop calling us names, we would be a little more gentle towards your feeling.

You flat our deserve to be critisizes. The truth of these sciences is they have been politically corrupted. Notice how attempting to understand every variable that diminishes the role CO2 can play is taboo. This is not science to talk about real variables that need further study.

What if it is garbage in garbage out?

See, your problem is you are 100% anti-science. Science demands that allow your hypothesis to be tested not only in manners to support it, but try to look at every thing that can nullify your hypothesis to claim the hypothesis has merit.

Why do you think climate papers are never explicit? The scientists know their work has a very wide margin of error for the real world. The scientists present the papers are results of the input variables, in a model. They know the models are insufficient. I say time and time again, I trust the science. I understand the science. But what you guys believe is what the pundits are saying. Not the actual research scientist who actually perform the work. And it is their actual work that I read. Not the pundits.

Repetitive standard talking points. I’ve heard it all from you dozens, and even hundreds of times. There never anything new, just plowing the same trite fields over and over.

Are you saying this is a negative? Of course they know there is margin for error. That is why they continue to do research and gather data while you sit around in an online chat room whining about it.
And they also know that the climate is steadily warming because of the human-produced CO2 that has been increasingly pouring into it since the dawn of the Industrial Revolution. Of that, according to the climate scientists, there is simply no doubt.

I'm just curious. If these climate change studies being done by these scientists came back and said there is no negligible climate rise in temperature, wouldn't their funding be cut off? So what do you think they are doing, a legitimate study, or a search for information to support their pre decided outcome?

Conspiracy theory/standard denier talking point.

It does not really work like that! For example say someone runs an experiment that finds that
the idea of centuries of warming are already in the pipeline, is largely a myth.
Ricke and Caldeira Maximum warming occurs about one decade after a carbon dioxide emission
They phrase their words in such a way as to say they found the same as earlier results.
This range is in keeping with contemporary estimates of transient climate response to cumulative carbon emission obtained in a number of studies (Collins et al 2013), though our metric is time-dependent so the values are not directly comparable.
Thus paying homage to the idea that everyone is finding similar results.
The actual findings were significant enough that a second study tested their findings.
The time lag between a carbon dioxide emission and maximum warming increases with the size of the emission
And while they could not contradict, the findings, they deflected them by saying that the
time lag was tied to the size of the emissions, bypassing the idea that even Ricke and Caldeira's
test pulse was ten times larger than the average Human emission.
