Since this post was originally published, the heat wave has continued. As of Thursday morning, it appears that average temperatures across the Northern Hemisphere have breached the 2 degrees Celsius above “normal” mark for the first time in recorded history, and likely the first time since human civilization began thousands of years ago. That mark has long been held (somewhat arbitrarily) as the point above which climate change may begin to become "dangerous" to humanity. It's now arrived—though very briefly—much more quickly than anticipated. This is a milestone moment for our species. Climate change deserves our greatest possible attention.

wow, but I guess it is all a fraud and bs, right?

Based on how many data points? Over what period of time?

"Recorded history"....

A hiccup in the grand scheme of things.

You don't understand, there is no alternative. There is only one Earth, if this one becomes uninhabitable for humans that's it. It will cost whatever it costs and take whatever it takes.

There's a few ways to stop the warming if we wanted to spend trillions of dollars.
1. Sulfur into the stratosphere would deflect a lot of the energy back into space.
2. A solar shade at the right distance from our planet to case a large "reduced" or block solar energy out during certain times.
etc


It is true that a few degrees wouldn't make this planet inhabitable but lets say for a second it started down the path to what happened to venus???(Super unlikely!!!!!!!!!!!!!!!!!!!!!!!!!!!) Well, I think it would be worth 10 trillion bucks if that was occurring.

We can do that without wasting trillions on windmills.

but lets say for a second it started down the path to what happened to venus

Yes, many impossible hypotheticals could waste trillions.

Well, I think it would be worth 10 trillion bucks if that was occurring.

I don't think wasting 10 trillion to prevent the impossible is a good idea.

Then when you figure you fisked up the planet you'd be screaming for 50 Trillion to fix what you screwed up. Your stupidity is that you think man is even remotely capable of controlling something as complex as the ecosystem.

Let me see.. The last bump of over 0.8 deg C was induced by El Niño and will fade fast over the next few months... Yet Mathew claims that it was all caused by man...

Get a fucking life man.. You alarmist-socialists are in this for two things.. MONEY AND POWER.. it has never been about mother earth.

So a 120PPM increase of CO2 raises temperature 2C? Is that what you're saying?

Here's the actual planetary temperature history for the last ten thousand years, from the experts at NOAA.m

What’s the hottest Earth has been “lately”?
NOAA
Author: Michon Scott
September 17, 2014

Difference from historic average temperature since last ice age. NOAA Climate.gov cartoon by Emily Greenhalgh. Inspired by Figure 1(b) in Marcott et al., 2014.

This article is the second of two articles describing the hottest time periods in Earth’s history.

Throughout its 4.54-billion-year history, Earth has experienced multiple periods of temperatures hotter than today’s. But as far as the “recent” past, a study published in March 2013 concluded that global average temperature is now higher than it has been for most of the last 11,300 years.

The scientists assembled dozens of temperature records from multiple studies, including data from sediment cores drilled in lake bottoms and sea floors, and from ice cores. Assembling data from 73 records that overlap in time, the scientists pieced together global average temperatures since the end of the last ice age.

The 11,000-year temperature reconstruction shows global average temperature increasing after the end of the last ice age and leveling off about 7550 and 3550 BC. After that time, global temperatures dropped until the "Little Ice Age," bottoming out somewhere between AD 1450 and 1850. Afterwards temperatures rose again, first slowly then very rapidly. (The estimated temperatures for the past 1,500 years correlated with previous research that covered the same time period.)

Global temperature anomalies over the past 11,300 years compared to historic average (1961-1990). The purple line shows the annual anomaly, and the light blue band shows the statistical uncertainty (one standard deviation). The gray line shows temperature from a separate analysis spanning the past 1,500 years. Image adapted from Figure 1(b) in Marcott et al.

Natural variability can explain much of the temperature variation since the end of the last ice age, resulting from factors such as changes in the tilt of the Earth's axis. Over the past century, though, global average temperatures have "risen from near the coldest to the warmest levels" in the past 11,300 years, the 2013 study authors explain. Over this same period, emissions of heat-trapping gases from human activities have increased.

Given the uncertainty inherent in estimating ancient temperatures, the scientists conservatively concluded that the last decade has brought global average temperatures higher than they have been for at least 75 percent of the last 11,300 years. The recent increase in global average temperature is so abrupt compared to the rest of the time period that when the scientists make a graph of the data, the end of the line is nearly vertical.

What about the future? To project future temperatures, the research team used greenhouse gas emission scenarios outlined in the Intergovernmental Panel on Climate Change (IPCC) Climate Change 2007: The Physical Science Basis report, and the authors expect the steep increase to continue through the year 2100 regardless of which one of the emission scenarios from the 2007 report is considered.

Most of what we consider modern civilization fits within the last 11,000 years—a period of remarkable climatic stability in which people have been able to continuously inhabit in the same regions for millennia. The United Nations Educational, Scientific, and Cultural Organization describes Tell es-Sultan (ancient Jericho) as "the oldest town on earth." Photo courtesy Seetheholyland.net (some rights reserved).

For most of the past 10,000 years, global average temperature has remained relatively stable and low compared to earlier hothouse conditions in our planet's history. Now, temperature is among the highest experienced not only in the “recent” past—the past 11,000 years or so, during which modern human civilization developed—but also probably for a much longer period.

Carrie Morrill of the National Climatic Data Center explains, "You'd have to go back to the last interglacial [warm period between ice ages] about 125,000 years ago to find temperatures significantly higher than temperatures of today."
