Abstract

Proponents of the hypothesis of anthropogenic global warming assert that the increase in carbon dioxide concentration in the atmosphere is the major contributor to the increase in surface temperature, due to the “greenhouse effect”. Climate forcing by CO2 is the largest forcing among all other anthropogenic greenhouse gases. The concentration of CO2 and other greenhouse gases have risen significantly. This paper attempts to the similarity/dissimilarity between CO2 emissions per person for most of the EU countries to segment EU nations. Idea is identify cluster of countries with high, medium and low growth similarity pattern of CO2 emission. Time series clustering is used to partition time series data into groups based on similarity, so that emission time series in the same cluster are close. Proponents of the hypothesis of anthropogenic global warming assert that there in surface temperature, due to the “greenhouse effect”. Global average temperature has raised .15⁰C per decade from 1976 to 2001 (IPCC). This paper analyzes the temperature data for EU nations from 1991 onwards. We tend to understand the average, minimum and maximum temperature change for the economies in the clusters. We build time series models to project the new forecast of temperature change for EU nations on an average, other than the given by existing models by IPCC. We forecasted temperature using time series forecasting models for five years.
