The four warmest Januarys documented in the climate record have all occurred since 2016, while the 10 warmest have occurred since 2002.
January 2020 also marked the 44th consecutive January and the 421st consecutive month overall with temperatures above the 20th century average, according to the release.

RE: Last month was the hottest January in 141 years of recorded climate histor
so let me get this straight...lefty's always talk about how they believe in science, not superstition. And the earth has been around how many years (A: The age of the Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%)...and these records have been kept for how many comparative seconds? Not even the blink of an eye...and news flash, earth has been a LOT hotter in the past than it will ever get again. Drivin' my gasoline-powered classic without no more emissions exams or cad converter, and luvin' it.
RE: Last month was the hottest January in 141 years of recorded climate histor
Yep... 141 years. Not even a moment in time compared to the 'climate'.
I'm not saying this proves anything else, but it certainly (by itself) doesn't prove nor even strongly suggest that man is the cause. It's possible, but only one of dozens of equally likely possibilities.
If we are indeed warming as suggested, then we need to take measures to adapt, at least as much as we're taking measures to correct.... mostly because it's far easier (and globally safer) to predict and adapt to (as an example) a 2 inch rise in sea levels than it is to simply count on our plans to 'save the planet' which have thousands of unknown variables and no reasonable predictive models to anticipate, much less adjust to along the way... Said differently, it is foolish to spend trillions on unproven and frankly, undiscovered technology that MUST work within a specified timeframe in order to avoid a predected tragedy when currently existing and predictable technology can mitigate many of the issues, should the 'solution' fail in any way.

1. Burning fossil fuels causes an increase in the CO2 concentration in the atmosphere.
Over the last 400,000 years, the CO2 concentration in the atmosphere oscillated between 180 and 300 ppm. We're at 416 ppm as of today.
2. When atmospheric CO2 and methane concentrations rise, so do temperatures.
Visible light from the sun travels through the atmosphere and refracts off the surface as infrared light (heat). Thanks to the atmosphere, a lot of this heat is retained before it can escape back out into space. Which is good. We'd freeze otherwise. The problem arises when there's too much greenhouse gasses in the atmosphere, as too much heat is retained, raising the average global temperature.
Our current average temperature has risen by about 1 degree Celsius compared to the pre-industrial average.
3. The global temperature doesn't have to change by that much to make everything go to hell.
A 5 degree Celsius decrease puts large portions of North America and Europe under a half a mile thick sheet of ice. A 6-10 degree increase turns the whole world into a giant tropical forest with sea levels 200 meters higher than present day. Also, it would make areas near the equator virtually uninhabitable.
Just a 2 degree increase is enough to make things very bad for us living on this pale blue dot of ours.
Quote:Most land regions will see more hot days, especially in the tropics. At 1.5 degrees Celsius warming, about 14 percent of Earth’s population will be exposed to severe heatwaves at least once every five years, while at 2 degrees warming that number jumps to 37 percent. Extreme heatwaves will become widespread at 1.5 degrees Celsius warming.
Limiting warming to 1.5 degrees Celsius would reduce the number of people frequently exposed to extreme heatwaves by about 420 million, with about 65 million fewer people exposed to exceptional heatwaves.
At Earth’s mid-latitudes, the hottest days will be up to 3 degrees Celsius (5.4 degrees Fahrenheit) hotter at 1.5 degrees Celsius warming and up to 4 degrees Celsius (7.2 degrees Fahrenheit) warmer at 2 degrees Celsius warming. The warmest extreme temperatures will be in Central and Eastern North America, Central and Southern Europe, the Mediterranean (including Southern Europe, Northern Africa and the near-East), Western and Central Asia and Southern Africa. Longer warm spells will affect many densely populated regions. At warming above 1.5 degrees Celsius, twice as many megacities as today are likely to become heat stressed, potentially exposing 350 million more people by 2050.
At 2 degrees Celsius warming, the deadly heatwaves India and Pakistan saw in 2015 may occur annually.

It's very interesting seeing you be so interested and invested in NASA and space exploration only to turn around and **** on the data and science NASA puts out.
Guess they're smart enough to send a space probe to the extents of our solar system but they're ******* clueless when it comes to climate change.

RE: Last month was the hottest January in 141 years of recorded climate history
Of course the temperatures are rising. What do you think happens when we constantly adjust historical temperatures lower and current temperatures higher? How else are we going to show warming if the data doesn't support our conclusion? *End of snark*

And exactly who was around 100s of thousands of years ago measuring CO2 and the temperature? Hogwash. Im still waiting for that Ice Age these same people were talking about in the 70s.

Here. Educate yourself.
Quote:Ice cores are cylinders of ice drilled from ice sheets and glaciers. They are essentially frozen time capsules that allow scientists to reconstruct climate far into the past. Layers in ice cores correspond to years and seasons, with the youngest ice at the top and the oldest ice at the bottom of the core. By drilling down into the ice sheet or glacier and recovering ice from ancient times, scientists are able to determine the past composition and behavior of the atmosphere, what the climate was like when the snow fell, and how the size of ice sheets and glaciers have changed in the past in response to different climate conditions. Ice cores have provided climate and ice dynamics information over many hundred thousand years in very high, sometimes seasonal, resolution. This information allows scientists to determine how and why climate changed in the past. By understanding how and why climate changed in the past, scientists are able to improve predictions of how climate will change in the future.
Because of their high time-resolution, the physical nature of their proxy records, and their ability to archive actual greenhouse (and non-greenhouse) gas concentrations from the past, ice cores have become one of the golden standards in paleoclimate research.
Quote:What can the ice tell us about past climates?
Each layer of ice tells a story about what Earth was like when that layer of snow fell. For example, LeGrande says, as snow deposits onto a growing glacier, the temperature of the air imprints onto the water molecules.
The icy layers also hold particles—aerosols such as dust, ash, pollen, trace elements and sea salts—that were in the atmosphere at that time. These particles remain in the ice thousands of years later, providing physical evidence of past global events, such as major volcanic eruptions.
Additionally, as the ice compacts over time, tiny bubbles of the atmosphere—including greenhouse gases like carbon dioxide and methane—press inside the ice. These air pocket “fossils” provide samples of what the atmosphere was like when that layer of ice formed, LeGrande said. “Scientists can directly measure the amount of greenhouse gases that were in the atmosphere at that time by sampling these bubbles,” she added.
RE: Last month was the hottest January in 141 years of recorded climate history
There was an ice age with very little environmental impact from humans, then something caused "global warming" and ended the ice age again with little to no impact from humans. Climate change is a normal cycle for the planet with or without 8billion humans.

Anytime I see someone trying to show a marked increase by adjusting the graph to a non-zero base, it usually means they need the graph to look as horrific as they can because their point needs it.
Your base graph showing 180ppm of CO2 is actually the lowest amount recorded in earths history. In other words, it could be a good thing that CO2 is rising because it was at a dangerously low level.
Plant life requires CO2. CO2 is not a bad thing.
In the past, CO2 levels have DOUBLED due to volcanic activity. When a volcano erupts and sends ash and CO2 into the atmosphere, its not a localized event. It sends it everywhere. Even to the poles.
