How confident are scientists that Earth will warm further over the coming century?

In a short guide explaining the science behind climate change, the Royal Society describes scientists as being “very confident” that the earth will continue to warm over the coming century. How confident are scientists that Earth will warm further over the coming century? Very confident. If emissions continue on...

How does climate change affect the strength and frequency of floods, droughts, hurricanes, and tornadoes?

Climate change will have substantial impact on the frequency of extreme weather events, from droughts to floods, according to the Royal Society. How does climate change affect the strength and frequency of floods, droughts, hurricanes, and tornadoes? Earth’s lower atmosphere is becoming warmer and moister as a result of...

If the world is warming, why are some winters and summers still very cold?

Weather variations and how this links to climate change has been addressed by the Royal Society in a short guide. If the world is warming, why are some winters and summers still very cold? Global warming is a long-term trend, but that does not mean that every year will...

Does the recent slowdown of warming mean that climate change is no longer happening?

The fact that rising temperatures have recently slowed down has been used as a reason by climate sceptics to claim manmade climate change is not occurring. However, in a short guide explaining climate science, the Royal Society shows why the figures do not disprove manmade climate change. Does the...

Does the rate of warming vary from one decade to another?

The pace of global warming varies from decade to decade and the Royal Society has explained why this is the case and what the differences mean. Does the rate of warming vary from one decade to another? Yes. The observed warming rate has varied from year to year, decade...

Is there a point at which adding more CO2 will not cause further warming?

‘Is there a point at which adding more CO2 will not cause for further warming?’ is one of the questions that Royal Society has answered in a guide that explains the science behind climate change. Is there a point at which adding more CO2 will not cause further warming?...

Is the current level of atmospheric CO2 concentration unprecedented in Earth’s history?

Atmospheric CO2 has almost certainly reached unprecedented levels, according to the Royal Society. Over the last 200 years the level of CO2 has increased rapidly. Is the current level of atmospheric CO2 concentration unprecedented in Earth’s history? The present level of atmospheric CO2 concentration is almost certainly unprecedented in the past...

Climate is always changing. Why is climate change of concern now?

Manmade climate change sceptics often argue that the climate is always changing and as a result human activities, such as burning fossil fuels, is not having a large impact. The Royal Society explains why the changes are now important. Climate is always changing. Why is climate change of concern...

What do changes in the vertical structure of atmospheric temperature — from the surface up to the stratosphere — tell us about the causes of recent climate change?

The Royal Society has produced a short guide to climate science that seeks to create informed conversations. It covers a range of topics, including what changes in the vertical structure of atmospheric temperature can tell us about climate change. What do changes in the vertical structure of atmospheric temperature...

CO2 is already in the atmosphere naturally, so why are emissions from human activity significant?

If CO2 is already part of the atmosphere, why is it important to limit emissions? is one of the questions the Royal Society seeks to explain.  CO2 is already in the atmosphere naturally, so why are emissions from human activity significant? Human activities have significantly disturbed the natural carbon cycle by extracting long-buried fossil fuels...
