Twenty years of blogging in hindsight

Real Climate

It shows the atmospheric concentrations of carbon dioxide (CO 2 ) and tells a story about the carbon cycle, involving Earth’s crust, the atmosphere, land surface, the biosphere, and the oceans. In a nutshell, they are responsible for climate change, mainly due to an increased greenhouse effect.

The Court Has Spoken: A Healthy Climate is a Human Right

Union of Concerned Scientists

The opinion included the key fact that 71% of greenhouse gas emissions between 1988 and 2017 could be traced to just 90 companies, the Carbon Majors. Along these same lines, the Court specified that certain business have greater responsibilities due to their cumulative, historical contributions.

A Framework for Equitable Climate Infrastructure Investments

Legal Planet

Achieving climate goals requires significant investments in clean energy, transportation, and other climate technologies to reduce greenhouse gas emissions and remove carbon from the atmosphere.

The most recent climate status

Real Climate

Thawing permafrost may release methane into the atmosphere, which subsequently increases the greenhouse effect and leads to further global warming. The overall Arctic ice loss has contributed far more to global sea-level rise than any other region on Earth.

WMO: Update on 2023/4 Anomalies

Real Climate

As well as the (now) standard set of graphs related to increasing greenhouse gas concentrations , rising temperatures , reducing glacier mass, etc., since the 1850-1900 baseline is very clearly associated with the increases in greenhouse gases, slightly (and decreasingly) modulated by the changes in atmospheric pollution.

How Major Carbon Producers Drive Sea Level Rise and Climate Injustice

Union of Concerned Scientists

Previous attribution research published by my Union of Concerned Scientists colleagues have allowed us to draw causal connections between sources of heat-trapping emissions and resulting impacts, like present day increases in atmospheric greenhouse gas concentrations, air temperatures, sea levels , ocean acidification , and wildfire burned area.

We also know what is needed to stop global warming: the atmospheric concentrations of greenhouse gases such as CO2 and methane must stabilise, and the forests must be protected.
