How do you find historical climate data?

First, find the location you need climate data for on the following map: https://www.weather.gov/ and click on that region. The Web site of the local WFO will then appear. On the left side of the page there will be a section called Climate in yellow-colored text. You may have to scroll down the page.

What is Cait data?

The Climate Analysis Indicators Tool (CAIT) is an information and analysis tool on global climate change developed by the World Resources Institute. CAIT provides a comprehensive and comparable database of greenhouse gas emissions data (including all major sources and sinks) and other climate-relevant indicators.

How far back does climate data go?

Here’s what’s going on: Scientists mark the start of modern global record-keeping at roughly 137 years ago, in 1880. That’s because earlier available climate data doesn’t cover enough of the planet to get an accurate reading, according to NASA.

Which country is the highest emitter of greenhouse gases?

The biggest culprit of CO2 emissions for these countries is electricity—notably, burning coal.

China. China is the largest emitter of carbon dioxide gas in the world, with 9.9 billion metric tons in 2019, the year for which the most recent data is available.
The United States.
India.
The Russian Federation.
Japan.

What is MTCO2e?

Metric tons of carbon dioxide equivalent or MTCO2e is the unit of measurement in this tool. The unit “CO2e” represents an amount of a GHG whose atmospheric impact has been standardized to that of one unit mass of carbon dioxide (CO2), based on the global warming potential (GWP) of the gas.

Why is it still important to reconstruct past climates?

Reconstruction of past climate provides clues about future climate change. — Greenhouse gases were the main driver of climate throughout the warmest period of the past 66 million years, providing insight into the drivers behind long-term climate change.
