What's Real Evidence of Climate Change? | Let's Talk | NPR

The climate has always changed – so why all of the focus on it now? It has a lot to do with predictability. NPR’s Christopher Joyce explains.

Sorry but 140 year sample of temperature out of what 7 billion years. Thats not a very reliable data set. The climate is complicated and I think its a very easy answer to just say we are causing it.

[mammothoff-roadersofcentra]

If they were truly concerned about our environment we would be using Hydrogen power in all our vehicles. Not EV’s that are charged by electricity that’s made with Coal burning…

I want the truth!! Where is the evidence it does or doesn’t exist?

I love how they misrepresented the graph. It only shows a 2 degree range and is super bunched up and not further spread out.
They made the graph look more intimidating than it is. Gotta love that bullshit lol

[victorgrauer]

The graph he displays at :14 does NOT show a "clear upward trend" as he claims. Nor does it illustrate a correlation between CO2 levels and either warming or sea level rise. In fact it does the opposite. But to understand this one actually has to KNOW something about the history of 20th century climate. From the beginnings of the industrial revolution until roughly 1950, CO2 levels were not high enough to have much of an effect on global temperatures. This FACT is acknowledged by most if not all climate scientists, who ascribe warming during this period to natural variation. From ca. 1940 to roughly1979, as clearly illustrated on the graph, there was no warming at all. Yet from 1950 on CO2 emissions were beginning to soar -- a clear example of counter-correlation. And from 1998 through ca. 2015 there was only a very slight increase, if any, in warming. And again, CO2 emissions were continuing to soar -- another anti-correlation.

This graph has been used to mislead people into believing that there's been a steady upward trend in temperatures since the beginning of the 20th century due to CO2 emissions, but as is clearly the case, that is not at all true. As for sea levels, they rose at a relatively steady rate throughout this entire period, despite the mid-century cooling and despite the fact that temperature rise due to CO2 emissions could not have have any effect on sea level during the 1st 80 years of the 20th century, nor during almost all of the 21st, as I've just explained.

He stated many “facts” supported by what??? Not a convincing video.

August 12, 1936 and June 28, 1994 – 120 degrees

As crazy as it sounds, there are two dates that tie for the hottest day in Texas history. The heatwave of 1994 earned the most spots on this list, but the summer of 1936 is the earliest super-hot day in history. On August 12, 1936,  Fort Worth and Seymour clocked in intimidating temperatures reaching 120 degrees.

I remember as a child, in the early 1980's being totally alarmed by global warming, i was told that by year 2000, the Maldives would be gone, anyone living near coasts would need to move inland. Here in 2024, none of this came to pass. The icebergs are melting, yet last year Antarctica had it's coldest winter on record. Who's telling the truth here? Nobody talks about the polar shift, which is so evident and has happened many times before.

[TRAW]

All these flat earth christian republicans trolling up the comments. #GND

[MrJudgementday]

Misleading title. It didn’t show any evidence

[maccasclips]

Why didn’t you show evidence on how you said that the temperatures are rising quicker that before?

[johndavid]

Nils-Axel Morner was a professor at the university of Stockholm where he was the head of paleogeophysics. He published a book called "the greatest lie ever told" the title giving away his position on climate change. It shouldn't take you long to read it.

"we live in a society"
with lots of (purposeful) errors in its reporting.

[ashdoodge]

I remember in the 70s global cooling was a thing. I remember acid rain being a huge thing. And there was even a hole in our ozone at one point that was a huge deal. Hacked is we don't pollute our are anywhere close to how we used to. one volcano puts off more toxic gas in the atmosphere then all of the cars on the planet combined throughout the history of the automobile.

[maureennorman]

haven't the ocean levels been rising for thousands of years? since the last ice age, haven't there been many citiies swallowed up by the ocean before the invention of the gas engine?

[Ryan-usjf]

He just said that water expands when it gets hotter. Doesn’t waters volume increase as it freezes?

[JustinsGarage]

So the Earth’s temp has been fluctuating since the beginning of time. How is the upward trend any different?

[MisterFusion]

This is a very, very bad job. I see charts with well known artificial adjustments and anecdotal evidence in the form of particular events. Please do a better job if you would like to make an argument for trillions of dollars of economic changes. - and don't include any lies if you want to build credibility. Why is that so hard to do for something that's absolutely certain?

[stevedoetsch]

0:17 "...oceans are rising." Instead of telling by how much they have risen, he fear mongers with a story about a localized flood from a hurricane that has nothing to do with rising oceans, but will trigger the fear of a large portion of the audience who he knows lives in the country. Floods from hurricanes are not the same as rising oceans, and he expects the audience not to realize that.

[John-liqi]

The problem I have with using the "recorded temperature increase" as "evidence" is because we only have 142 years of recorded temperature, and while some may think that's a lot; in comparison to the age of the Earth we are talking about determining a factor based on of data compared to the full age of the Earth. Is the Climate increasing? I think yes. Have Humans contributed to this? I think yes. But I do not believe human action has contributed even close to the scale that is being represented today.
