“But Data”

It’s all about data.

Examples

All the climate scientists are faking their data for funding.

Objections and Replies

Adjustments. All data are adjusted, therefore they’re crap—
☞ Welcome to reality. Embrace crappiness or you’ll remain unhappy {1}.

Better. If only we could have a better resolution of—
☞ A pixel-by-pixel representation of the Earth with absolutely exact temps at each point of the time continuum would indeed be great. Until then what we got will have to do {2}

Buckets.

Error. If your data is corrupt or inaccurate then your result will be erroneous—
☞ According to thy Wiki, random errors “can be estimated by comparing multiple measurements, and reduced by averaging multiple measurements.” Systematic errors only affect absolute measurements. Anomalies will be fine.

Global Temperature. A single temperature for Earth isn’t poss—
☞ Zero-dimensional models do that.

Greenland. Don’s graph of Greenland shows that—
☞ Don surely can be economical with the truth.

Metrics.

No. There is no data set to complete your claim —
☞ Where have you checked?

Satellites. Satellites

Sea level. There has not been a long-term distinctive change in sea level—
There has. You’re not listening to Tony, Pierre or Kenneth, are you?

Stations.

Theory. When theory and data clash, its the theory that has to be modified—
☞ Only if you have adamant data, which is seldom the case and an invincible model, which never is.

Troposphere.

Urban Heat.

Notes

{} Crappiness. Databases are crap. Let’s embrace crappiness instead of channeling impossible demands of perfection.
