Boring: Global Warming Is A Global Issue

I thoroughly enjoy writing, especially about environmental issues and how to make the environment we live in a better place. What is causing global warming and what indicates humans are the primary cause of the warming we have been witnessing? These are important questions since understanding the causes can help us come up with viable solutions.

Scientists Global Warming Is A Global Issue studied a number of climate indicators that point to human activities being the cause of recent global warming. Understanding these indicators is the key to understanding why the vast majority of scientists have concluded that our activities are the primary cause of the recently observed global warming and the changes in climate that the warming has been linked to.

A depiction of the greenhouse effect and how it affects Earth. Carbon exists click three isotopes different weights based on Iw number of neutrons in a carbon atom. Carbon, which has 8 neutrons, accounts for an infinitesimal amount of approximately 1 in 1 trillion carbon atoms.

Fossil fuels primarily come from plants that decomposed while buried underground under immense pressure for millions of years.

As fossil fuels are burned, they increase the ratio of carbon versus carbon in the atmosphere. This increase of carbon in the carbon ratio has been documented in recent decades via direct measurements by scientists that research the composition of the atmosphere. Past carbon ratio data is derived from tree rings and ice cores. The data indicate the carbon versus carbon ratio in the atmosphere has increased by approximately 0. While this sounds like a rather small and insignificant increase, it is approximately five times greater than the documented carbon versus carbon ratio increase of 0.

This rapid increase in carbon clearly points to a human cause rather than a natural cause for the observed increase in carbon in the atmosphere since and the associated atmospheric warming. Scientists have collected data of the Earth's global average temperature going back 12, years. Inter-glacial warm periods, which occur between glaciations, typically last between 10, and 12, years. The current interglacial warm period that human civilization has developed in started approximately 11, years ago. The temperature trends in the preceding graph click that global temperatures peaked about 7, years ago, then made a sustained move lower.

Scientific Evidence That Links Mankind’s Activities to Global Warming

The geologic record indicates we were heading into a new ice age right on schedule. This slide to a cooler regime was interrupted in recent decades, as global temperatures quickly moved well above the high mark set 7, years ago. This sudden spike in global temperatures which interrupted a sustained natural downtrend is another indication that the sudden Global Warming Is A Global Issue we have been experiencing is not just natural variation. The geologic record indicates that the Earth is currently warming far faster than it has in the past. So fast that a natural explanation makes no sense. For the global average temperature to rise by one degree Celsius in only a matter of approximately years is quite unusual in comparison to natural warming observed in the geologic record. An indication that the recent warming is not likely due to natural variability.

The various climate drivers that have affected global temperatures in recent decades are depicted above.

A climate driver is something that causes the climate to warm or cool over time. Other climate drivers have either had a negative or minimally positive impact on global temperatures. The Tropopause is between the Troposphere and Stratosphere.

The recent movement outward of the Troposphere Atmospheric Transition Zone Tropopausewhich is the boundary between the Troposphere and the Stratosphere, is yet another indicator of human-caused global warming. Once released, these gases would cause additional warming, leading to additional melting and releases of gases, and on and on until the Earth is substantially warmer than it is today.

To address global warming, it is imperative that we take measures to ween human civilization off of fossil fuels and transition our societies to run off Global Warming Is A Global Issue non-carbon dioxide emitting renewable energy, and to take these measures as more info as possible. In light of the fact that we either might not have the will to change over to renewable energy or it might already be too late to do so, as future runaway global warming may already be inevitable, we should also start planning on implementing geoengineering solutions to stop and reverse global warming.
